AB  - Maintaining modern intensive plantations requires the latest practical and theoretical
knowledge, the application of which achieves top-quality production results. In recent years, more
and more attention has been paid to both energy efficiency and environmental aspects as the
ultimate goal of the sustainability of each production. The sustainability of a process can limit
reaching the maximum of said process. In the technologies of soil maintenance in perennial
plantations in recent years, it becomes imperative that the chemical treatment of the soil,
immediately adjacent to the plant and within the row, be replaced by mechanical processing. This
need is primarily aimed at minimizing the use of pesticides in order to respond to the
environmental requirements. Regular land cultivation is a technically complex problem. The given
area is made up of up to 25% of the total land area of the plantation. The paper presents the
results of testing a rotary harrows with a deflection, which in one pass achieves the processing of a
part of the inter-row surface and half of the protective zone. The results of the research show that
the optimal speed of movement of the aggregate carried out in the plantation of the orchard is 1,56
m/s, and in the plantation of the vineyard 1,23 m/s. Productivity of aggregates in the orchard 0,24
ha/h, in the vineyard 0,19 ha/h. Fuel consumption in the vineyard 7,2 l/ha, and in the orchard 6,8
l/ha. Productivity of the aggregate is largely conditioned by the technical solution of the aggregate
and the technology of plantation cultivation.

AB  - The paper presents the results of three different ways of storing the dried mass of hay: bulk, small bales
and large roll bales, as well as the impact of three drying methods: natural in the field, artificial drying with cold
air and drying with dehumidification (warm air). In the tested meadow in the first swath, the results of chemical
analyses showed differences in the method of drying hay. Regarding the tested drying method, the content of
dry matter (DM) had significant differences between the storage methods as well as all variants with pre-heated
air drying, where the average value of DM was in the interval of 86.18-93.01%. The content of mineral
substances for certain methods of preparation and drying ranged from 5.77% to 7.72% on average. The highest
content of crude proteins was in all variants of artificial drying and it ranged from 98.6 to 165.7 g/kg DM and
had a statistically significant difference. Both methods of artificial post-drying had a significant impact on the
cellulose content (33.76% to 28.86%) compared to drying in the traditional way because postponing the
mowing time increases the cellulose content. The drying method had a statistically high significant difference
on the content of neutral detergent fibres (NDF) and acidic detergent fibres (ADF), while the method of
storage had no major impact. Knowledge of changes in the quality of hay during the growing season is of
particular importance form the aspect of ruminant nutrition and balanced rations. The amount and quality of
obtained hay is significantly affected by the time of mowing, height of mowing, swath, fertilization, floristic
composition and weather conditions during drying of the green mass.

AB  - The technical accuracy of the machine is a prerequisite for the effective
implementation of chemical protection in fruit and grapevine production. The paper
presents the results obtained during the control testing of 50 different models of
orchard sprayers, with different period of exploitation in growers throughout Serbia
that are used in intensive fruit and grapevine production. During the control testing, a
large number of parameters were monitored, using standardized methods and test
procedures. Comparison of the obtained data was applied to four groups of orchard
sprayers (defined by the period of the exploitation). The technical accuracy of the
individual orchard sprayer is expressed by the coefficient of the technical correctness
(Cta) according to individual marks of the tested parameters of orchard sprayers.
Out of the total number of investigated orchard sprayers, 12% of the orchard sprayers
are in exploitation for less than three years, while the largest number of orchard
sprayers, and 42% is in exploitation for seven years or more. The technical accuracy of
Group 1 orchard sprayers was sufficiently high, except for the parameters related to
the Measuring regulatory system (Cta = 0.80) and the Nozzles (Cta = 0.86). In Group 2,
a decrease in the coefficient of technical accuracy in all parameters was observed with
respect to the sprayers from Group 1, which was particularly pronounced for Agitators
(Cta = 0.50) and Nozzles (Cta = 0.68). The orchard sprayers from Group 3 are
characterized by a low coefficient of technical accuracy for the Nozzles (Cta = 0.37),
while Group 4 orchard sprayers have a very low coefficient of technical accuracy in all
tested parameters. The level of technical accuracy of the orchard sprayers used in
intensive fruit and grapevine production is directly dependent on the period of their
exploitation.

AB  - In this study, drying kinetics of autochthonous variety Požegača plum was examined in a laboratory dryer at three temperatures. The whole plum fruits, together with the kernels were subjected to the drying process. The effect of drying has been examined at temperatures of 55, 60 and 75°C, with a constant air velocity of 1.1 m s-1. The corresponding experimental results were tested using six nonlinear regression models. Coefficient of determination (R2), standard regression error (SSE), model correlation coeficient (Vy), as well as the maximum absolute error (ΔY) showed that the logaritmic model was in good agreement with the experimental data obtained. During drying of plums, the effective diffusivity was found to be between 5.6×10-9 for 55°C and 8.9×10-9 m2 s-1 at 75°C, respectively. The physical characteristics of fresh (length 39.64 mm and width 29.15 mm) and dried (length 37.52 mm and width 22.85 mm) plum fruit were determined. Finally, by chemical analysis, the contents of micro- and macro-elements (Fe, Mn, Cu, B and N, F, K, Ca, Mg and S) in the skin and flesh of the dried product, prunes, has been established.

AB  - The presented study is to develop a mathematical model of convective drying of plums in the prototype dryer, in order to apply the developed model to other similar types of fruit. Since the dried plums are one of the traditional dried products of many regions in Serbia, this is the main reason for selecting the analysis. A mathematical model of drying plums is based on the fundamental laws of mass and heat transfer. Along with the development of mathematical models, experimental measurements were carried out during drying plum in the prototype dryer and then the results were compared for validation. Three models were carried out, in the range of drying temperatures of 45ºC to 73ºC. Two drying models were divided in several phases (heating, hypothermia and drying), and one model had only one phase of drying. By comparing the data obtained by numerical simulation and experimental data, it can be concluded that the mathematical model is successfully developed.

S obzirom da je sušenja šljiva jedan od tradicionalnih sušenih proizvoda ovog regiona, to je bio glavni razlog odabira za analizu. Matematički model sušenja šljive bazira se na osnovnim zakonima prenosa mase i toplote. Uporedo sa razvojem matematičkog modela, vršena su eksperimentalna merenja tokom sušenja šljive u prototipskoj sušari, a zatim su poređeni rezultati u cilju validacije. Vršena su tri testa sušenja u opsegu temperatura od 45ºC do 73ºC. Eksperimentalni deo ispitavanja podeljen je u tri režima sušenja sa po više faza (zagrevanje, pothlađivanje i sušenje). Poređenjem podataka dobijenih numeričkom simulacijom i podataka dobijenih iz eksperimenta, može se zaključiti da je matematički model uspešno razvijen.

Matematički model sušenja šljive bazira se na osnovnim zakonima prenosa mase i toplote. Uporedo sa razvojem matematičkog modela, vršena su eksperimentalna merenja tokom sušenja šljive u prototipskoj sušari, a zatim su poređeni rezultati u cilju validacije. Vršena su tri testa sušenja u opsegu temperatura od 45ºC do 73ºC. Eksperimentalni deo ispitavanja podeljen je u tri režima sušenja sa po više faza (zagrevanje, pothlađivanje i sušenje). Poređenjem podataka dobijenih numeričkom simulacijom i podataka dobijenih iz eksperimenta, može se zaključiti da je matematički model uspešno razvijen.",

AB  - Fruit production under arid conditions without irrigation implies the need to employ soil cultivation in the entire orchard with the aim of regulating the water-air regime of the soil, contributing to a favorable soil structure, breaking down the soil crust and successful weeds destruction. Contemporary fruit cultivation practices are compulsory in order to achieve high yields and profitability. Additional soil tillage in orchards has a major impact on the growth and development of plants, yield and fruit quality. Optimal parameters need to be determined when employing mechanization equipment in orchard cultivation in order to make the right choice. The objective of the study was to determine energetic and exploitation parameters of different tractor/machinery tools used in additional soil cultivation. Based on the analysis of the data obtained showing both advantages and disadvantages of some soil cultivation types, it was possible the choose the optimal tool for additional soil tillage. Field trials were carried out in apple (cv. Jonagold, Idared and Melrose) orchards using the two-row Pilar cultural practice at a planting distance 3.80-1.25 x 140-1.80 m. The following tools for additional soil cultivation were used: pseudo plow PP-220, plate cultivator VVT - 223, cultivator IMT-642 and vineyard plow VP-189. The following exploitation indices were monitored: traction force, labor speed, fuel consumption and traction resistance. Based on the results obtained the smallest fuel consumption was registered using pseudo plow (3.78 l/ha) whereby cultivation depth, speed and output registered were 6.31 cm, 7.29 km/ha and 9.07 ha/day respectively.
AB  - Proizvodnja voća u aridnim uslovima bez navodnjavanja zahteva obradu zemljišta na čitavoj površini u cilju regulisanja vodno-vazdušnih osobina zemljišta, stvaranja pogodne strukture, razbijanja pokorice i uništavanja korovske vegetacije. Primena takve tehnologije gajenja voća je neophodna za ostvarenje visokih prinosa i ekonomične proizvodnje. Zbog toga dopunska obrada zemljišta u višegodišnjim zasadima ima značajan uticaj na rast i razviće biljaka, prinos i kvalitet plodova. Pravilan izbor i korišćenje sredstava mehanizacije ima presudan uticaj na intenzivnost voćarske proizvodnje. Napredak u tehnologiji gajenja voća podrazumeva korišćenje najsavremenijih tehničkih sredstava za obavljanje agrotehničkih mera. Za pravilan izbor pojedinih sredstava mehanizacije značajno je utvrditi optimalne parametre njihove primene u obradi zemljišta.

AB  - In intensive fruit production, especially in fruit farms, high yields are achieved. Large number of fruits makes organization of picking and further manipulation very challenging. Transport issue in fruit production was always attendant, but in extensive technologies was solved by engaging larger number of labor. Because of the specific production, transport in this section represents complex and combining problem depending on a large number of factors. From previous reasons the objective of this study was to investigate four different ways of apple fruits manipulation from between row distance. Experiment was done in 6-year-old apple orchard, with planting distance 5 x 3 m, with modified spindle bush training system. Results from this study made possible to define the method that demanded the least labor for the nearest time period. Time consumption of apple transport from orchard was recorded over number of cycles and fruit quality. The pallets-system during apple harvest time represented positive trend in decreasing of time necessary for transport up to three times. This fact refers to the necessity of more often pallet-system transport applying.
AB  - Intenzivnom voćarskom proizvodnjom naročito u plantažnim zasadima ostvaruju se visoki prinosi po jedinici površine. Velika količina plodova usložnjava organizaciju ubiranja i dalje manipulacije. Problem transporta u voćarskoj proizvodnji oduvek je bio prisutan a kod ekstenzivnih tehnologija se rešava većim angažovanjem radne snage. Transport u ovoj oblasti zbog specifičnosti, predstavlja složen i kompleksan problem a čine ga veći broj faktora. Iz prethodno navedenih razloga predmet istraživanja u ovom radu su bila četiri različita načina iznošenja plodova jabuka iz međureda zasada.

Rezultati istraživanja su omogućili definisanje postupka koji angažuje najmanje ljudskog rada i ostvaruje se za najkraći vremenski period. Vreme utrošeno na proces izvoženja plodova iz voćnjaka je praćeno preko broja ciklusa i kvaliteta plodova. Primena sistema paletizacije u procesu berbe jabuka, pokazuje pozitivan trend u smanjenju vremena transporta po jedinici prinosa i do tri puta.

AB  - Harvesting represents one of the most challenging problems in managing vineyards. 'Quality picking' is considered when it is done in the period when the grapes are suitable for its purposes, especially related with the soluble solid content, and the appropriate sugar/acids relation. Hand picking costs represent around 45% of total labor per hectare, which is equivalent of 30-50 working days for one laborer. Study of the mechanical picking of grapevine cultivars intended for winemaking by applying dragged combine 'Volentieri' ensemble with tractor 'New Holland Tn 95 F' are shown in this paper. Experiment was done in the Ćemovsko Field's production vineyards, with cultivars Vranac and Župljanka. Grapevine planting was done on the planting distance 2.6 x 0.7 m and 2.6 x 1 m, respectively. Row length was 168 m, with training system modified horizontal bilateral cordon with green strip width in grape area 50-60 cm. Aggregate's working results of the investigation are showing that average running speed was 4.8 km/h, and output 0.62 ha/h, i.e. 4.98 ha/day in cultivar Vranac. In cultivar Župljanka following values were achieved: running speed was 4.1 km/h, output 0.53 ha/h i.e. 4.24 ha/day. Turning time in headlands of examined harvester was 30 - 32 s. It was necessary to reduce green leaves just before harvesting, especially in the zone bunches, in order to decrease slowdowns and losses. Dragged combines, except in larger plantations, have commercial adequacy both in smaller households.
AB  - Jedan od najsloženijih problema u obavljanju radnih operacija u vinogradarstvu predstavlja proces berbe grožđa. Kvalitetna berba se smatra ona koja se obavi u periodu kada sastav grožđa odgovara njegovoj nameni, što se pre svega odnosi na suvu materiju i odgovarajući odnos šećera i kiselina. Troškovi ručne berbe grožđa čine oko 45% od ukupnog utroška ljudskog rada po hektaru što odgovara 30-50 radnih dana jednog radnika. U radu su prikazani rezultati ispitivanja mehanizovane berbe vinskih sorti grožđa, primjenom vučenog kombajna 'Volentieri' u agregatu s traktorom 'New Holland Tn 95 F'. Ispitivanja su obavljena na proizvodnim površinama Ćemovskog polja, sorte Vranac i Župljanka. Sadnja loze je obavljena na međurednom i rednom rastojanju 2,6 x 0,7 m i 2,6 x 1 m. Dužina redova je iznosila 168 m a zastupljen uzgojni sistem je modifikovana horizontalna dvokraka kordunica sa širinom zelenog pojasa u zoni grožđa 50-60 cm. Rezultati ispitivanja agregata u radu pokazuju da je ostvarena prosječna radna brzina od 4,8 km/h, a učinak 0,62 ha/h tj. 4,98 ha/dan - sorta Vranac. Kod sorte Župljanka ostvarene su vrednosti: brzina rada 4,1 km/h, učinak 0,53 ha/h tj. 4,24 ha/dan. Pri radu kombajna javljaju se gubici od 36 kg/ha kod sorte Vranac, a 70 kg/ha kod sorte Župljanka. Vreme okretanja na uvratinama ispitivanog kombajna je iznosilo 30 -32 s. Neposredno pred berbu neophodno je zelenom rezidbom smanjiti lisnu masu posebno u zoni grožđa kako bi se smanjili zastoji u berbi i gubici. Vučeni kombajni, osim u većim plantažnim zasadima imaju ekonomsku opravdanost i na manjim posjedima.

AB  - More and more rigorous ecologic EU regulations are placing the users of the equipment for pesticides applying in front of the large challenges. Legislation frame for pesticides and machines applying are changing continually. Because of the legal codes effects, it is necessary that mechanization used in plant protection dose precise, without any losses and with equal dispose in order to achieve the optimum success in plant protection with the minimal amount of pesticide and simultaneously protect the environment.

AB  - Basic land cultivation in orchards with the aim of loosening the soil is of major importance affecting both growth and development of plants, yield and quality of fruits. The right choice of agricultural machinery presents the precondition in intensive production. Determination of optimal parameters in the employment of agricultural machinery and its appropriate choice are of principal interest for the improvement of fruit growing and cultivation. The aim of the research was to determine both energetic and exploitation parameters of different tractors and machinery aggregates in basic soil cultivation. The analysis of the data obtained was used to choose the optimal system and pointed to the advantages and disadvantages of different types of cultivation. The results obtained from the investigation of basic soil cultivation in inter-rows showed the most rational cultivation using plough pseudo because the depth achieved was 14.27 cm, speed 6.47 km/h, consumption 7.28 l/ha and output 8.23 ha/day. Under arid conditions without irrigation it is necessary to employ soil cultivation on the whole area in order to regulate the water-air properties of the soil, contribute to an appropriate structure by breaking the crust and controlling weeds and in that way achieve high yields and profitability.

AB  - Sprinklers with plane jet have excellent quality of distribution, and are equally suitable for protection from weeds, illnesses and pests. Known multiphase (universal) and anti- drift sprinklers are replaced with injector sprinklers. The most significant advantage of injector sprinklers is minimization of drift which, according to the results of the research, may be up to 75 %.

AB  - The experiment conducted in the vineyard using sprayers was aimed at analyzing the effect of air flow rate and sprayer movement rate on pesticide droplets deposition on leaf surface. The concentration used was 350 l/ha. Ventilator capacity was changed obtaining the following air flow rates in front of vineyard rows: 5.2; 7.5; 9.8 and 13.5 m/s. Air flow rates were combined with different sprayer movement rates (5.8 and 8.5 km/ha) in order to obtain eight variants. Increasing sprayer movement rate from 5.8 to 8.5 kg/h tended to raise pesticide droplets deposition by 25% in the row facing the sprayer, or 10% on the opposite side of the row. It can be concluded that droplets deposition on the leaf surface was the greatest at the sprayer movement rate of 5.8 kg/ha and air flow rate ranging from 8 to 10 m/s.

AB  - Previous investigations have proved the fact that Serbia has a substantial renewable energy potential amounting to more than 3 million tons petrol equivalents annually. The share of biomass accounts for approx. 80% of the potential. At the same time, total consumption of fossil fuel is 12 million tons petrol equivalents. If Serbia, spending about 2.5 million tons petrol equivalents per year, were to use only 10% of its biomass potential, i.e. 2.6 million tons petrol equivalents in order to meet household heat energy needs, about 60 million Euros would be saved as a result of import decrease. Optimal technological and technical solutions should be defined with regard to collecting, loading, transporting and preparing pruning remains in orchards and vineyards with the aim of obtaining energy. This is expected to have a significant influence on the energetic efficiency of fruit growing and is an issue of major concern. In our country collecting, preparing and using pruning remains is not widely used due to the irrational disposal of energy and extensive production. Pruning remains have their advantage as sustainable energy source being at the site of consumption or its vicinity. The simplest and oldest way of using pruning remains as energents in the process of burning and producing heat energy is to burn the unchanged remains. Considering the bulk of it which is characterized by the irrational transport, impeded loading, unloading, storing and use in combustion equipments.

AB  - Lasting several years of experiences in process of mechanical plum and sour cherry harvesting, together with technical solutions of foreign production, made us develop domestic technical solution. By technical advancing of machine prototype, satisfactory functionality and working capacity was reached. Based on our past experiences, we considered that three years period is necessary to perfect shaker prototype by improving its functionality and working capacity. This paper contains short technical description of the machine and two-year exploitation results obtained on different localities in plum and sour cherry orchards. Vibration type machine is consists of two main devices: for tree swinging and for collecting knocked fruits. Principles of machine work are based on reciprocal impact of two masses that result occurrence of inertial forces of fruit in tree fruit canopy. During exploitation period, the shaker was part of a jointed mechanism together with tractor IMT-539, and four workers served it. Obtained results were based on following aggregate work in two years period, and are showing that averagely it takes around 1.5 minutes per tree in first six vegetations of plum orchards. In plum orchard where trees are above seven years old, average time spent per tree was around 2 minutes. Shaking process in both groups was 9-12 seconds. Investigation results of the shaker in sour cherry orchards, no matter of the age was between 1.0-1.5 minutes per tree. The amount of the unshaken fruits in both fruit species was up to 3%, and the amount of the fruit that fell out of the collector was around 1% considering gathered fruits.
AB  - Višegodišnja iskustva u ranijem vremenskom periodu u procesu mehanizovane berbe šljiva i višanja, tehničkim rešenjima inostrane proizvodnje, navela su nas da pristupimo razvoju domaćeg tehničkog rešenja. Tehničkim usavršavanjem prototipa mašine dostignuta je zadovoljavajuća funkcionalnost i radni kapacitet. Period od tri godine smatrali smo neophodnim, da na osnovu prethodnih iskustava, usavršimo prototip tresača, poboljšavajući mu fukcionalnost i kapacitet rada. Rad sadrži kratak tehnički opis mašine i rezultate dvogodišnje eksploatacije koja je realizovana na različitim lokalitetima u zasadima šljive i višnje. Mašina vibracionog tipa sastoji se od dva glavna uređaja: za njihanje voćke i za prihvatanje otrešenih plodova. Princip rada mašine se zasniva na međusobnom dejstvu dveju masa koje prouzrokuju pojavu inercijalnih sila plodova u krošnji voćke. Tokom eksploatacionog ispitivanja tresač je bio agregatiran s traktorom IMT-539 a opsluživalo ga je četiri radnika. Rezultati dobijeni na osnovu dvogodišnjeg praćenja rada navedenog agregata pokazuju da je u proseku potrebno oko 1,5 min vremena po stablu u zasadima šljive starosti do 6 godina. U zasadima šljive starosti iznad 7 godina prosečno utrošeno vreme po stablu je iznosilo oko 2 min. Sam proces trešenja i jednih i drugih stabala je iznosio od 9-12 s. Rezultati ispitivanja tresača u zasadima višnje, bez obzira na starost, se kretala između 1,0-1,5 min/stablu. Količina neotrešenih plodova kod obe vrste voća se kretala do 3% a količina plodova koja je pala van uređaja za prihvatanje je iznosila oko 1% u odnosu na prikupljene plodove.

abstract = "Lasting several years of experiences in process of mechanical plum and sour cherry harvesting, together with technical solutions of foreign production, made us develop domestic technical solution. By technical advancing of machine prototype, satisfactory functionality and working capacity was reached. Based on our past experiences, we considered that three years period is necessary to perfect shaker prototype by improving its functionality and working capacity. This paper contains short technical description of the machine and two-year exploitation results obtained on different localities in plum and sour cherry orchards. Vibration type machine is consists of two main devices: for tree swinging and for collecting knocked fruits. Principles of machine work are based on reciprocal impact of two masses that result occurrence of inertial forces of fruit in tree fruit canopy. During exploitation period, the shaker was part of a jointed mechanism together with tractor IMT-539, and four workers served it. Obtained results were based on following aggregate work in two years period, and are showing that averagely it takes around 1.5 minutes per tree in first six vegetations of plum orchards. In plum orchard where trees are above seven years old, average time spent per tree was around 2 minutes. Shaking process in both groups was 9-12 seconds. Investigation results of the shaker in sour cherry orchards, no matter of the age was between 1.0-1.5 minutes per tree. The amount of the unshaken fruits in both fruit species was up to 3%, and the amount of the fruit that fell out of the collector was around 1% considering gathered fruits., Višegodišnja iskustva u ranijem vremenskom periodu u procesu mehanizovane berbe šljiva i višanja, tehničkim rešenjima inostrane proizvodnje, navela su nas da pristupimo razvoju domaćeg tehničkog rešenja. Tehničkim usavršavanjem prototipa mašine dostignuta je zadovoljavajuća funkcionalnost i radni kapacitet. Period od tri godine smatrali smo neophodnim, da na osnovu prethodnih iskustava, usavršimo prototip tresača, poboljšavajući mu fukcionalnost i kapacitet rada. Rad sadrži kratak tehnički opis mašine i rezultate dvogodišnje eksploatacije koja je realizovana na različitim lokalitetima u zasadima šljive i višnje. Mašina vibracionog tipa sastoji se od dva glavna uređaja: za njihanje voćke i za prihvatanje otrešenih plodova. Princip rada mašine se zasniva na međusobnom dejstvu dveju masa koje prouzrokuju pojavu inercijalnih sila plodova u krošnji voćke. Tokom eksploatacionog ispitivanja tresač je bio agregatiran s traktorom IMT-539 a opsluživalo ga je četiri radnika. Rezultati dobijeni na osnovu dvogodišnjeg praćenja rada navedenog agregata pokazuju da je u proseku potrebno oko 1,5 min vremena po stablu u zasadima šljive starosti do 6 godina. U zasadima šljive starosti iznad 7 godina prosečno utrošeno vreme po stablu je iznosilo oko 2 min. Sam proces trešenja i jednih i drugih stabala je iznosio od 9-12 s. Rezultati ispitivanja tresača u zasadima višnje, bez obzira na starost, se kretala između 1,0-1,5 min/stablu. Količina neotrešenih plodova kod obe vrste voća se kretala do 3% a količina plodova koja je pala van uređaja za prihvatanje je iznosila oko 1% u odnosu na prikupljene plodove.",

AB  - Intensive soil preparation including both mechanical and human labor is required prior to the planting and establishment of orchards. Due to energy deficiency during the past years attention was focused on rational technology with the aim of decreasing energy input in the cultivation stage. Trenching up to 40 cm (in some cases up to 120 cm) is considered the most demanding operation in the soil cultivation stage. Attempts were made to substitute the trenching operation, however it is still the most important stage on some soil types in practice. In our practice tenching is the traditional technology of soil cultivation for orchard establishment. It is of major importance for loosening the B glay horizon in heavy soil types. It also contributes to favorable conditions for the development of the root system. The aim was to analyze the energetic aspect of trenching by determining fuel consumption per unit of time and cultivated area prior to orchard establishment. In addition, the structure of working hours was monitored as well. Also, technical features of the trenching aggregate were given. The conclusion emerges that energy requirements in the trenching stage may amount to 250 kWh/ha at 72 cm cultivation depths. Therefore, attention should be focused on rational soil cultivation prior to orchard establishment. .

U radu je obrađen energetski aspekt duboke obrade rigolovanjem utvrđivanjem potrošnje goriva po jedinici vremena i obrađenoj površini koja se obavlja pre podizanja višegodišnjih zasada. Ispitivanjima su bili obuhvaćeni sledeći pokazatelji: brzina kretanja, vučni otpor, klizanje gusenica, vučna snaga, radni zahvat, specifični otpor zemljišta i učinak. Pored ispitivanja eksploatacionih parametara obavljeno je snimanje strukture radnog vremena. Pored toga date su tehničke karakteristike ispitivanog agregata u rigolovanju. Osnovni zaključak je da rigolovanje angažuje veliku energiju koja se kreće i do 250 kWh/ha za dubine obrade od 72 cm tako da je neophodno posvetiti značajniju pažnju racionalnijim načinima obrade zemljišta pre podizanja višegodišnjih zasada.

AB  - Huge amounts of plant remains are obtained following pruning, an essential agricultural practice measure during the exploitation of orchards and vineyards. Different pruning modes are employed depending on the size of the orchard and the available machinery. The remains tend to hinder other activities in the orchard but on the other hand they represent an essential energetic source. The energy can be transformed or returned into soil by mulching. Collecting and burning of the remains but also further cutting into small pieces and plowing itself were elimination modes of former technologies. However, these procedures contributed to the loss of a useful and important source of heat energy. Optimal technological and technical solutions should be defined with regard to collecting, loading, transporting and preparing pruning remains in orchards and vineyards with the aim of obtaining energy. This is expected to have a significant influence on the energetic efficiency of fruit growing and is an issue of major concern. In our country collecting, preparing and using pruning remains is not widely used due to the irrational disposal of energy and extensive production. Pruning remains have their advantage as sustainable energy source being at the site of consumption or its vicinity. The simplest and oldest way of using pruning remains as energents in the process of burning and producing heat energy is to burn the unchanged remains. Considering the bulk of it which is characterized by the irrational transport, impeded loading, unloading, storing and use in combustion equipments. Ecological issues and fossil energy deficiency impose the need to focus on the preparation and use of pruning remains as energetic fuel in orchards. The issue has gained in importance following the regulations imposed by the EU whereby renewable energy sources should be used in the production of electrical energy.

abstract = "Huge amounts of plant remains are obtained following pruning, an essential agricultural practice measure during the exploitation of orchards and vineyards. Different pruning modes are employed depending on the size of the orchard and the available machinery. The remains tend to hinder other activities in the orchard but on the other hand they represent an essential energetic source. The energy can be transformed or returned into soil by mulching. Collecting and burning of the remains but also further cutting into small pieces and plowing itself were elimination modes of former technologies. However, these procedures contributed to the loss of a useful and important source of heat energy. Optimal technological and technical solutions should be defined with regard to collecting, loading, transporting and preparing pruning remains in orchards and vineyards with the aim of obtaining energy. This is expected to have a significant influence on the energetic efficiency of fruit growing and is an issue of major concern. In our country collecting, preparing and using pruning remains is not widely used due to the irrational disposal of energy and extensive production. Pruning remains have their advantage as sustainable energy source being at the site of consumption or its vicinity. The simplest and oldest way of using pruning remains as energents in the process of burning and producing heat energy is to burn the unchanged remains. Considering the bulk of it which is characterized by the irrational transport, impeded loading, unloading, storing and use in combustion equipments. Ecological issues and fossil energy deficiency impose the need to focus on the preparation and use of pruning remains as energetic fuel in orchards. The issue has gained in importance following the regulations imposed by the EU whereby renewable energy sources should be used in the production of electrical energy. The aim is to solve the lack of eco energy and contribute to environmental protection., Tokom eksploatacije višegodišnjih zasada pored ostalih kao obavezna agrotehnička mera sprovodi se i rezidba kojom se dobija velika količina biljne mase u obliku ostataka rezidbe.

AB  - One of the most important pomotechnical action for fruit and vine care is pruning. One of the problems which occur as a result of pruning is how to remove biomass from field. In extensive technology this problem is solved by pickup and combustion biomass or chopping and plowing. In both cases biomass is lost as energetically valuable and quantitatively important source of the thermal energy. There for, in order to enhance energetic efficacy, obtaining the optimal technology and technical solutions for the use of fruit and vine pruning residues is a very important task. In our region as a result of extensive production and non rational energy management, collection processing, preparation and using vegetable residues is not in use. The advantage of the use of energy obtained from biomass relies in the fact that the residues obtain on the place of consumption, or in their surrounding. One of the oldest usage of the biomass is the use of it as an energent for heating. In order to obtain better result it is important to prepare biomass. Nowadays the interest to use biomass for obtaining electrical energy or other more valuable fuels increase.

AB  - The paper shows the results of the three year long experiments with hidraulic pruner HR-85 for pruning apple kinds (Starking Delicious, Jonathan, Golden Delicious) on stock seedling. The increase of height band width of crown during the period of investigation was different and was dependent of kind way of pruning and years of investigation. Necessary time for pruning ranged with: mechanized pruning from 14,47 (Jonathan) to 17,59 s/tree(Starking Delicious); mechanized pruning with hand correction from 569,46 (Golden Delicious) to 585,79 s/tree (Starking Delicious); with hand pruning from 832,53 (Jonathan) to 976,60 s/tree (Golden Delicious). Average working speed was 2,18 (Starking Delicious) to 2,64 km/h (Golden Delicious). The efficiency of the pruner is 52,24 (Starking Delicious) to 64,82 (Golden Delicious) times higher than manual pruning. On the basis of investigation it was established that with: Starking Delicious kind there is the influence of way of pruning to the yield; Jonathan and Golden Delicious kinds there is no the influence of way of pruning to the yield.
AB  - U radu su dati trogodišnji rezultati ispitivanja hidrauličnog rezača HR-85 u rezidbi jabuke (starking, jonatan, zlatni delišes) na podlozi sejanac. Prirast visine i širine krune u ispitivanom periodu bio je različit i zavisio je od sorte, načina rezidbe i godine ispitivanja. Vreme za rezidbu kretalo se kod mehanizovane rezidbe od 14,47 (jonatan) do 17,59 (starking) s/stablo mehanizovane rezidbe sa ručnom korekcijom od 569,46 (zlatni delišes) do 585,79 (starking) s/stablo; kod ručne rezidbe od 832,53 (jonatan) do 976,60 (zlatni delišes) s/stablo. Kod jabuke starking postoji, a kod jabuka jonatan i zlatni delišes ne postoji uticaj različitih načina rezidbe na prinos.
