AB  - Basic soil tillage in perennial plantations is still present in agro-ecological conditions of R.Serbia despite the tendency for grassing the inter-row space. The reasons for this include arid climatic conditions, as well as the lack of an irrigation system requiring great investments. Mechanical soil tillage provides some advantages over the procedures of soil grassing. These advantages primarily relate to the rational distribution of moisture in the soil, prevention of the development of harmful rodents, better aeration of soil as well as an effective application of organic fertilizers. The paper presents comparative exploitation surveys in soil tillage with a conventional plough, subsoilers and rotary hoes in perennial plantations. The exploitation testing covered determination of working depth, working speed, pulling resistance, front and rear wheel load, performance and fuel consumption. The results of the survey show that apart of having better tractor static load distribution when it is in aggregate with the rotary hoe, this combination has a potential of lowering the fuel consumption. This aggregate has 17% lower fuel consumption compared to the subsoiler usage and 29% lower consumption compared to the plough usage. The main conclusion is that the performance indicators of the working methods described should be analysed in further research. To-date experience shows that the operation of the rotary hoe compared to the standard plough results in lower intensity of the soli mixing and lower intensity of plant residues incorporation in the soil.
AB  - Osnovna obrada zemljišta u višegodišnjim zasadima i pored tendencija zatravljivanja međurednog prostora još uvek je prisutna u agroekološkim Republike Srbije. Razlog za to su aridni klimatski uslovi kao i nedostatak tehničkih sistema za navodnjavanje za čije korišćenje su potrebne velike investicije. Mehaničkom obradom zemljišta ostvaruju se određene prednosti u odnosu na postupke zatravljivanja. Te prednosti pre svega se odnose na racionalnim raspolaganjem sa vlagom u zemljištu, sprečavanje razvoja štetnih glodara, bolja aeracija zemljišta, kao i efikasno unošenje organskih đubriva. U radu su prikazana uporedna eksploataciona istraživanja pri obradi zemljišta klasičnim plugom, razrivačem i rotacionim ašovom u višegodišnjim zasadima. Ispitivanjima su obuhvaćeni parametri: dubina obrade, vučni otpor, oterećenje prednjih i zadnjih točkova, brzina kretanja, učinak i potrošnja goriva. Rezultati istraživanja u ovom radu pokazuju da pored bolje statičke raspoređenosti opterećenja traktora u radu agregata traktor - rotacioni ašov u odnosu na obradu oranjem i razrivanjem, značajne su i uštede u potrošnji goriva po jedinici površine. Potrošnja goriva kod obrade rotacionim ašovom je manja za oko 17 % u odnosu na podrivanje i do 29 % u odnosu na oranje klasičnim plugom.

AB  - A good spatial distribution and adequate choice of the orchard establishment system will enable the application of mechanisation decreasing thereby the share of manpower in major labour processes and increasing simultaneously productivity in fruit growing. The results of fruit tree planting were analysed showing productivity of technical equipment used. The study focused on single drill tractor, hydroborer and automatic planter output. Based on the results obtained the output achieved was the highest in using planter, followed by hydroborer and drill. Holedrilling output depended mostly on terraine, soil preparation and training of those in charge of aggregates.
AB  - Dobra organizacija teritorije i adekvatan izbor sistema uzgoja zasada, omogućuje primenu mehanizacije tako da se udeo ljudskog rada u obavljanju radnih operacija znatno smanjuje i time povećava produktivnost pri gajenju višegodišnjih zasada.

abstract = "A good spatial distribution and adequate choice of the orchard establishment system will enable the application of mechanisation decreasing thereby the share of manpower in major labour processes and increasing simultaneously productivity in fruit growing. The results of fruit tree planting were analysed showing productivity of technical equipment used. The study focused on single drill tractor, hydroborer and automatic planter output. Based on the results obtained the output achieved was the highest in using planter, followed by hydroborer and drill. Holedrilling output depended mostly on terraine, soil preparation and training of those in charge of aggregates., Dobra organizacija teritorije i adekvatan izbor sistema uzgoja zasada, omogućuje primenu mehanizacije tako da se udeo ljudskog rada u obavljanju radnih operacija znatno smanjuje i time povećava produktivnost pri gajenju višegodišnjih zasada.

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.

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. .

Obzirom da se poslednjih godina zbog deficita energije, velika pažnja poklanja primeni racionalnih tehnologija kojima će se postići smanjenje utroška energije pri obavljanju operacija u obradi. Kao najzahtevnija operacija u pripremi zemljišta predstavlja duboka obrada-rigolovanje zemljišta na dubini preko 40 cm, a za neke zasade čak i do 120 cm.

Zatim, obezbeđenje povoljnih uslova za razvoj korenovog sistema, pogotovu ako se ima u vidu da višegodišnji zasadi ostaju i nekoliko desetina godina na jednom mestu. 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  - The paper presents the results of the two-year long experiments with mechanized plum pruning of cv Stanley with hydraulic pruner HR-85 powered by tractors Rakovica 65 and Torpedo TD 75A. The results suggest that mechanized pruning is more widely applied in plum production and processing. Index of productivity of mechanized pruning with manual correction and mechanized pruning in comparison with manual pruning ranges from 1,50 to 87,94, depending on the condition of the orchard, average for two years investigation from 1,90 to 58,5.
AB  - Rad predstavlja rezultate istraživanja mehanizovane rezidbe šljive sorte stenley. Rezidba je obavljena hidrauličnim rezačem HR-85 u agregatu sa traktorima Rakovica 65 i Torpedo TD 75A. Rezultati ispitivanja pokazuju da se mehanizovana rezidba može koristiti u proizvodnji šljive za industrijsku preradu. Indeks proizvodnosti mehanizovane rezidbe sa ručnom korekcijom u odnosu na ručnu rezidbu je 1,50 i mehanizovane rezidbe u odnosu na ručnu je 87,94 što je zavisilo od stanja zasada, odnosno prosečno za dve godine ispitivanja 1,90 odnosno 58,5.

abstract = "The paper presents the results of the two-year long experiments with mechanized plum pruning of cv Stanley with hydraulic pruner HR-85 powered by tractors Rakovica 65 and Torpedo TD 75A. The results suggest that mechanized pruning is more widely applied in plum production and processing. Index of productivity of mechanized pruning with manual correction and mechanized pruning in comparison with manual pruning ranges from 1,50 to 87,94, depending on the condition of the orchard, average for two years investigation from 1,90 to 58,5., Rad predstavlja rezultate istraživanja mehanizovane rezidbe šljive sorte stenley. Rezidba je obavljena hidrauličnim rezačem HR-85 u agregatu sa traktorima Rakovica 65 i Torpedo TD 75A. Rezultati ispitivanja pokazuju da se mehanizovana rezidba može koristiti u proizvodnji šljive za industrijsku preradu. Indeks proizvodnosti mehanizovane rezidbe sa ručnom korekcijom u odnosu na ručnu rezidbu je 1,50 i mehanizovane rezidbe u odnosu na ručnu je 87,94 što je zavisilo od stanja zasada, odnosno prosečno za dve godine ispitivanja 1,90 odnosno 58,5.",

AB  - The goal our investigation was to investigated several the scissors for pruning, to show which models have less operation force at pruning of twigs apple, plum, peach and sour cherry. Investigation in show to investigated scissors cut easily twigs the sour cherry, peach, plum and apple. At the apple, for diameter of twigs 6,9 mm the best shows scissors Platinium 11/23 for diameter of twigs higher 7,00 mm the best was scissors Kuker. At the sour cherry was like, but for diameter twigs higher 8 mm was better the scissors kuker. At the plum and the peach the best showed the scissors Kuker.
AB  - Istraživanje je pokazalo da se ispitivanim makazama najlakše režu grančice višnje, breskve, šljive i jabuke. Kod jabuke, za prečnike grančica do 6,9 mm najbolje su se pokazale makaze platinium 11/23, a za prečnike grančica veće od 7,00 mm najbolje su bile makaze kuker. Slično je bilo i kod višnje s tim što su makaze kuker bile bolje za dijametar grančica većih od 8,00 mm. Kod šljive i breskve najbolje su se pokazale makaze kuker.

AB  - The advancement of technical and technological systems of the process of drying of stone fruits and constant improvement in the specific field do not diminish ongoing problems. Both practical and theoretic discoveries in the field of drying of stone fruits have been recently predominantly directed both towards the aspect of energy and the quality of the obtained products. The paper includes electric technical measurements of technological parameters relevant for the consumption of thermal energy within the process of drying of stone fruits. Temperature and air humidity at drying, drying speed and specific consumption of energy were primarily measured. Soluble solids content, the total and direct invert, sucrose and the total acids were recorded as quality parameters. Obtained results suggest that technical parameters of the system, primarily energetically part of the system, play key role in the energy consumption, besides the drying regime, type and method of preparation of the material.

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  - In Serbia classical sprayers with axial low-spray ventilators are still used in pest and disease control in fruit growing. These sprayers are characterized by huge amounts of air discharged into uncontrollable directions. However, the amount of energy utilized is enormous, the quality of control very poor which eventually contributes to environmental pollution. Currently there are various technical solutions for solving the issue in practice. These solutions however have not been tested on scientifically proved grounds in order to enable the right choice of machinery for the use in fruit growing. Considering the above said the need arises to conduct a comparative study of a few technical solutions from the standpoint of exploitation and constructive use in fruit growing. The classical sprayer with low axial spraying ventilars was the control. The investigation also included: a sprayer pointing its air current backward at askance and a sprayer with flexible tubes (OFC) pointing upward at an angle of 20 and 40°. Treatments were conducted in two types of orchards differing in leaf density. The conclusion which emerges is a 20% better quality of the control conducted with sprayers having axial ventilators and flexible tubes and a 30% gain of the preparation used in comparison with the classical sprayer. There were no differences in less dense fruit trees planted at a 3 m distance. The effect of the treatments on the uniformity of the distribution was insignificant. Sprayers with flexible tubes at an angle of 40° tended to increase the variation of the deposited preparation in less dense trees in comparison with dense tree crowns. The amount deposited by sprayers with air currents pointed backward at askance and OFC at an amble of 20° were by 1.3-1.7-fold smaller in less dense trees in comparison with more dense tree crowns.
AB  - Pri zaštiti voćnjaka u Srbiji se još uvek najviše koriste klasični orošivači sa aksijalnim niskovodenim ventilatorima. Karakteristika tih orošivača je velika količina vazdušne mase neadekvatnog usmerenja, što za posledicu ima angažovanje velike količine energije, loš kvalitet zaštite kao i znatno zagađenje životne sredine. Prisutna je i činjenica da se našoj voćarskoj praksi poslednjih godina nudi veoma veliki broj različitih tehničkih rešenja za zaštitu višegodišnjih zasada. Pojavljivanje velikog broja tehničkih rešenja nije propraćen odgovarajućim ispitivanjima naučnih institucija na osnovu kojih bi se izvršio odabir adekvatnih mašina proizvodnim uslovima u voćarstvu. Imajući na umu navedeno, nametnula se potreba da se obavi konstruktivno i eksploataciono upoređivanje više tehničkih rešenja orošivača koji se nude našoj voćarskoj praksi. Kao baza za poređenje uzet je klasični orošivač sa niskovodenim aksijalnim ventilatorom. Proces ispitivanja je još obuhvatio: orošivač sa usmerenjem vazdušne struje koso unazad i orošivač sa fleksibilnim cevima (OFC) usmerenim pod uglom od 20o i 40o na gore. Tretmani su obavljeni u dva tipa zasada koji se razlikuju po bujnosti. Zaključak je da orošivači sa aksijalnim ventilatorom i fleksibilnim cevima za usmerenje vazdušne struje ostvaruju bolji kvalitet zaštite do 20%, dok se ušteda zaštitnog sredstva kreće i do 30% u odnosu na klasični orošivač. Kod manje bujnih voćaka sa razmakom sadnje od 3 m nisu primećene nikakve razlike. Tretmani su imali neznatan uticaj na uniformnost distribucije izraženu koeficijentom varijacije. Kod orošivača sa fleksibilnim cevima promena ugla mlaza sa 20o na 40o za manje bujne voćke uslovila je povećanje varijacije depozita za razliku od bujnijih gde je primećeno određeno smanjenje varijacije. Količina depozita kod primene orošivači sa usmerenjem vazdušne struje koso unazad i OFC sa uglom usmerenja 20o za manje bujni zasad su bile 1,3-1,7 puta veći nego kod bujnijih stabala.

AB  - Electronic systems in modern plant protection equipment and machinery were introduced with the objective of achieving optimal efficacy of pesticide application but also contributing to cost decrease and environmental protection. In developed countries pesticide application expenses account for 30-40% of the production costs. On the other hand in underdeveloped countries with inappropriate control measures significant losses have been registered in the production of fruits. In conventional plant protection equipment irrespective of the size of the target area the amount of pesticides discharged by sprayers remains the same. Pesticides are unevenly sprayed on fruit trees with large crowns. Substantial amounts of pesticides are lost between crowns but also on the margins of crowns due to the lack of the vegetative mass. In practice there are pesticide rates which eventually contribute to efficient fruit crown treatment. These are however too high when it concerns its marginal parts. In developed European countries with enhanced agricultural production electronic control systems are used with the objective of adapting the application rate to the amount of leaves, the vegetative mass. The system enables a higher application rate for the crown parts of the fruit tree especially its central part. Crown margins receive lower application rates and eventually the inter row spacing is left untreated. A comparison study of the conventional and adapted sprayer showed that 37% of the pesticide used was saved using the adapted sprayer whereby the efficacy of the treatments was identical. Pesticide residues on the soil between the fruit trees were negligible pointing to efficient environmental protection.

AB  - Mechanized processes of raspberry and blackberry harvesting evolved to a great part from the fact that the share of manual harvesting accounts for about 70% of the total production costs. The rising trends of raspberry and blackberry production in some European countries (primarily Poland and Hungary), i.e. EU member countries, has greatly increased competitiveness on the domestic market. In our country raspberry and blackberry were produced on smaller farms using manual harvesting. In the EU member countries the enhanced development of raspberry and blackberry production is characterized by large raspberry and blackberry fields with mechanized labor processes including harvesting. This type of production has decreased production costs and exploitation of orchards including the price of raspberry and blackberry on the world market. The aim of the study was to define exploitation and technical parameters effecting the possibility of mechanized harvesting achieving high profitability and ensuring high quality of the fruits harvested. In addition the experience of mechanized harvesting of raspberry under the conditions of our country is described. Tractor aggregates or self propelled machines are considered acceptable from the standpoint of our knowledge and experience in the harvesting of small fruits depending however on the growing system and size of the orchard.

abstract = "Mechanized processes of raspberry and blackberry harvesting evolved to a great part from the fact that the share of manual harvesting accounts for about 70% of the total production costs. The rising trends of raspberry and blackberry production in some European countries (primarily Poland and Hungary), i.e. EU member countries, has greatly increased competitiveness on the domestic market. In our country raspberry and blackberry were produced on smaller farms using manual harvesting. In the EU member countries the enhanced development of raspberry and blackberry production is characterized by large raspberry and blackberry fields with mechanized labor processes including harvesting. This type of production has decreased production costs and exploitation of orchards including the price of raspberry and blackberry on the world market. The aim of the study was to define exploitation and technical parameters effecting the possibility of mechanized harvesting achieving high profitability and ensuring high quality of the fruits harvested. In addition the experience of mechanized harvesting of raspberry under the conditions of our country is described. Tractor aggregates or self propelled machines are considered acceptable from the standpoint of our knowledge and experience in the harvesting of small fruits depending however on the growing system and size of the orchard. Taking into consideration the high price of the machines and the sensitivity of small fruits the improvement of the machine can be achieved by adding the parts required thus contributing to a rational and profitable use., Činjenica da ručna berba maline i kupine učestvuje i do 70 % ukupnih troškova proizvodnje, upućuje na nužnost mehanizovanja procesa berbe.

AB  - In both controlled spaces and plastic greenhouses it is essential to maintain the optimum conditions for undisturbed development of growing plants. Energy of the sun radiation reaching plastic greenhouses changes considerably in the course of the day. This energy is basically smaller than potential radiation energy because of: ionization and absorption of gas in atmosphere appearance of clouds and atmosphere pollution, changes in air density caused by atmosphere pressure, changes in angle of light rays fall on transparent part of plastic greenhouse and so on. All these changes bring about substantial variations on climate conditions in plastic greenhouses and cause negative conditions for plants development. Thereby it is very important to regulate automatically the energy entering into and emitting out of plastic greenhouses. One way of automatic or manual regulation of both entering and emitting energy is the transmission through Polaroid foils. Here are considered two possibilities of entering solar energy regulation into plastic greenhouse as well as prevention of energy emission out of plastic greenhouses. The first possibility is by Polaroid foils, and the second one is by liquid crystals. The quantity of transmitted energy into plastic greenhouse depend on Polaroid foils position in the first case and on potential (voltage) discrepancy in the second case.
AB  - U kontrolisanim prostorima kao i u plastenicima je veoma bitno održavati optimalne uslove za nesmetani razvoj gajenih biljaka. Energija zračenja Sunca koja dopire do plastenika znatno se menja u toku dana. Ona je znatno manja od potencijalne energije zračenja zbog jonizacije i apsorpcije gasova u atmosferi, te pojave oblaka i zagađenosti u atmosferi, zatim promene gustine vazduha zbog delovanja atmosferskog pritiska, promene ugla padanja svetlosnih zraka na prozirni deo plastenika i td. Sve ove promene uslovljavaju znatna variranja klimatskih uslove u plastenicima čime se stvaraju nepovoljni uslovi za razvoj biljke. Zbog toga je veoma važno da se ulazna i emitovana energija iz plastenika automatski reguliše. Jedan od načina automatske ili ručne regulacije kako dozračne, tako i emitovane energije je transmisija energije kroz polaroidne folije. Razmatrane su dve mogućnosti regulacije ulazne solarne energije u plastenik, kao i sprečavanje isijavanja energije iz plastenika. Prvi način je pomoću polaroidnih folija a drugi način je pomoću tečnih kristala. Količina transmitovane energije u plastenik kao i količina isijane energije iz plastenika zavisila bi od položaja polaroid folija u prvom slučaju, a od razlike potencijala (napona) u drugom slučaju.

AB  - Mechanized harvesting processes of table pome fruits are an issue of major concern. Although there has been substantial enhancement in the mechanization used in pome fruit orchards, manual harvesting is known to be primarly employed. Modern technical solutions focused on platforms are used in order to increase output and eventually productivity. The objective of the study was to obtain data with regard to the application of self propelled platform, a modern technical solution used in apple harvesting. Investigations were conducted in 9-year old orchards using cultivars Idared, Jonagold, Golden Delicious and Granny Smith. Spindle bush growing orchards with interrow and row spacing 3,6x1.5 -1,7m was employed. The platform was investigated on a plot size of 3,66ha with 53 rows and an average number of 120 trees yielding 19,5hg/tree. Manual harvesting only was used as the control. Based on the results obtained harvesting time amounted to 520 minutes or 86,7%, aggregate turning time at the end of the row was 464 minutes or 77,4%. The total time for palette box change amounted to 41 minutes or 6,8% and halting time needed to take down palette boxes was 15 minutes or 2,5%. The number of harvested trees per shift was 600, i.e. the average time needed to harvest a tree was 0,45min. Output per apple picker was determined to be about 100kg at average fertility of 20kg/tree and engaging 8 apple pickers. Harvest output using the platform was found to be affected by orchard conditions, personnel training, harvest organization (delivering empty and loading full palette boxes). Orchard conditions are primarily characterized by the growing method, plant distribution, crown height, row length, fertility per tree, fruit size, variety, interrow area etc. Technical parameters of the platform need permanent improvement in order to raise harvest output.
AB  - U radu su prikazani rezultati eksploatacionih ispitivanja samohodne platforme savremenog tehničkog rešenja primenjene u procesu berbe jabuka. Ispitivanja su obavljena u zasadu starosti devet godina na sortama: Ajdared, Jonagold Zlatni delišes i Greni Smit. Zasad je međurednog i rednog rastojanja 3,6 x 1,5-1,7m, uzgojnog oblika vretenasti žbun. Rezultati istraživanja pokazuju da je prinos plodova po stablu u znatnoj meri varirao po pojedinim sortama a u proseku iznosio je 19,5kg/stablu. U toku dana optimalno vreme za berbu je bilo 10h od koga proizvodno vreme je iznosilo 520min što čini 86,7%. Sam proces berbe u toku dana je trajao 464min odnosno 77,4%. Za date uslove zasada uz pomoć ispitivane platforme koju su opsluživali osam radnika postignut je učinak po jednom beraču u proseku 300kg/h, obzirom da je učinak pri ručnoj berbi bez pomoćnih sredstava iznosi u proseku 100kg, predstavlja odnos 3:1.

Orchard conditions are primarily characterized by the growing method, plant distribution, crown height, row length, fertility per tree, fruit size, variety, interrow area etc. Technical parameters of the platform need permanent improvement in order to raise harvest output., U radu su prikazani rezultati eksploatacionih ispitivanja samohodne platforme savremenog tehničkog rešenja primenjene u procesu berbe jabuka. Ispitivanja su obavljena u zasadu starosti devet godina na sortama: Ajdared, Jonagold Zlatni delišes i Greni Smit. Zasad je međurednog i rednog rastojanja 3,6 x 1,5-1,7m, uzgojnog oblika vretenasti žbun. Rezultati istraživanja pokazuju da je prinos plodova po stablu u znatnoj meri varirao po pojedinim sortama a u proseku iznosio je 19,5kg/stablu. U toku dana optimalno vreme za berbu je bilo 10h od koga proizvodno vreme je iznosilo 520min što čini 86,7%. Sam proces berbe u toku dana je trajao 464min odnosno 77,4%. Za date uslove zasada uz pomoć ispitivane platforme koju su opsluživali osam radnika postignut je učinak po jednom beraču u proseku 300kg/h, obzirom da je učinak pri ručnoj berbi bez pomoćnih sredstava iznosi u proseku 100kg, predstavlja odnos 3:1.",
