AB  - The occurrence of late spring frosts due to climate change causes great damage to plantation production worldwide. The main objective of the paper is to provide a comprehensive overview of the problem and to outline effective protective measures against late spring frosts. The nature of frost depends on regional, altitudinal, and geographic differences, but they all share a common problem: they remove heat, resulting in the freezing of new plant growth and flowers. Tissue freezing is affected by critical temperatures and the frost type, intensity, and duration. Protection against late spring frosts can be broadly divided into three categories: active, passive, and chemical measures. In the field of agricultural engineering, various techniques have been thoroughly researched, and their effectiveness has been confirmed by research. These include various sprinkler systems, different heating devices, and large-diameter fans. Conclusive findings are being made on the performance of these systems in sub-zero temperatures and their cost-effectiveness. Climate change increases the importance of protecting permanent crops from late spring frosts and requires advances in agricultural technology to meet changing production demands and challenges

AB  - Increased demand for food production, influenced by the constant growth of population, resulted in the agricultural production systems that are more energy and economy intensive. The aim of this study was to evaluate the energetic and economic efficiency of sugar beet and wheat production. Attention was given to the fertilizer usage and its share in energy consumption since it can amount to 50%. Data show that energy input in wheat production was 5.84 MJ.kg(-1) and in sugar beet it was 0.93 MJ.kg(-1). The highest share of energy input both in wheat and sugar beet was observed for fertilizers, 52.45% and 46.70%, respectively. Economic analysis has shown that wheat production is a low profitable production with a net return of only 20.69 USD.ha(-1), in comparison with sugar beet production with a net return of 513.53 USD.ha(-1). Costs related to the fertilizer use prevailed in total variable and total production costs. Economic analysis has also shown that the benefit-to-cost ratio was higher in sugar beet production (1.33) compared to wheat production (1.03). Furthermore, it was determined that these economic indicators were less sensitive in sugar beet production than in wheat production regarding the variation of fertilizer.

AB  - The efficiency of primary agricultural production is under constant analysis relative to energy, economy and ecology. Notwithstanding technological innovations in agricultural production, engineers and researchers are still seeking to create a production system that would render the primary agricultural production more energy efficient and ecologically sustainable. The purpose of this paper is to examine the energy consumption and efficiency of crop production with an emphasis on the importance of mineral fertilizers and their influence on the overall energy consumption. The results obtained indicate that mineral fertilizers claim a share of the total energy consumption in crop production ranging from 40.53 % in sunflowers to 55.19 % in maize. A statistically significant correlation was found between the energy inputs for fertilizers and crop yields. The regression analysis performed showed a positive correlation between the energy inputs for fertilizers and yields in all the crops considered, with the exception of wheat.
AB  - Efikasnost primarne poljoprivredne proizvodnje je predmet konstantnih analiza, kako energetskih tako i ekonomskih i ekoloških. Bez obzira na tehničko unapređenje proizvodnje, i dalje se traže proizvodni i tehnološko-tehnički sistemi koji će dati energetski efikasniju i ekološki održivu primarnu biljnu proizvodnju. U radu je prikazan bilans potrošnje energije u proizvodnji ratarskih kultura i skrenuta je pažnja na mineralna đubriva. Potrošnja energije je praćena u proizvodnji pšenice, kukuruza, semenskog suncokreta, šećerne repe i soje, tokom tri proizvodne sezone. Data je analiza potrošnje energije kroz sve postupke manipulacije mineralnim đubrivima do i od imanja pa do same aplikacije na parceli. Analizirana je zavisnost ukupnih energetskih inputa i prinosa i korelacija utroška mineralnog đubriva i outputa. Rezultati istraživanja pokazuju da mineralna đubriva, u energeskom bilansu ratarske proizvodnje, učestvuju sa 40,52% (semenski suncokret) pa do 55,19% (kukuruz). Najintenzivniji utrošak energije po jedinici površine zabeležen je u proizvodnji šećerne repe, 27848,9 MJ ha-1 dok je najmanje energije utrošeno kod soje, 11371,28 MJ ha-1. Proizvodnja šećerne repe je energetski najproduktivnija (1,58 kg MJ-1). Najviše energije, kod manipulacije i aplikacije đubriva, je utrošeno u proizvodnji pšenice, 14,54 MJ ha-1, a najmanje u proizvodnji soje, 3,23 MJ ha-1. Statistička analiza je pokazala da postoji korelacija između energije utrošene preko đubriva i samog prinosa ratarskih kultura. Funcionalna veza između inputa putem đubriva i prinosa je jaka u svim slučajevima osim kod soje. Regresione jednačine pokazuju pozitivnu zavisnost između prinosa i uložene energije preko đubriva, osim u slučaju pšenice i semenskog kukuruza.

AB  - In this paper the influence of greenhouse construction type on energy efficiency of tomato and lettuce production was analysed. Influence of greenhouse construction on energy consumption was estimated for four different double plastic covered greenhouses. Specific energy input, energy output-input ratio and energy productivity were estimated in the tomato and lettuce production. Results show that there are differences in energy efficiency regarding the production as well as regarding the type of construction. The average energy input in greenhouse tomato production was 24.13 MJ m(-2) while in lettuce it was 3.19 MJ m(-2). Results also showed that the type of greenhouse construction has a significant influence on the energy efficiency of the greenhouse tomato and lettuce production. Greenhouses with the higher specific volume, in both cases had the higher energy output, higher energy efficiency, higher energy ratios and higher energy productivity.

AB  - In this paper, two different approaches in analyzing the tractor lifetime assessment are presented. The first one is based on reliability theory and the other one is based on the relevant experience that was implemented in the ASABE standards. In this way, the dependence of tractor reliability and lifetime on working conditions is presented through two models verified in the paper. Tractors from two different producers were analyzed. Experimental data were collected during the tractor working engagement at the fields of Agricultural Corporation Belgrade (ACB). Analyzing the obtained data it is possible to find the mismanagement in the tractor usage. Removing them it is possible to extend the period of tractor utilization. In this way the overall organization of tractor- machinery system on a farm can significantly be improved.

AB  - Soya (Glycine) is one of the most important crop plant. It produces products for human and domestic animals and processing industry. It is an important protein and oil plant. The soybean seeds contain more proteins (35-50%) and fats (17-24%) and fewer carbohydrates than others leguminous plants. Research of the Claas Lexion 430 combine harvester in a mercantile soybeans harvest shown that losses in uncut pods were in all measurements above tolerant 2% and ranged from 2.46% to 2.94%. Losses on the thresher in the free grain were ranged from 0.18% to 0.34% on average to 0.26%, which is satisfactory in relation to the given 0.3%. The average losses in the unthreshedpods are 0.35%, which is more than the projected level, but for the conditions of harvesting it can be accepted as satisfactory, due to the large percentage of weeds in the field.

AB  - The aim of this study was to analyze the impact of various systems of soil tillage and nitrogen doses on the mineral composition of the grain of the common winter wheat cultivar (Triticum aestivum ssp. vulgare), cv. Azra selected for the conventional intensive production. The field experiment was conducted on luvic chernozem in completely randomized blocks. Wheat was grown under three soil tillage systems: conventional tillage, mulch tillage and no -tillage, and the experiment included two doses of N fertilization (60 and 120 kg ha(-1)). Concentrations of eighteen elements (As, Al, Ba, Ca, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Ni, S, Sr, P, V and Zn) in wheat grain samples were determined by means of inductively coupled plasma with optical emission spectrometry (ICP OES). The results indicated that concentrations of the studied elements in the wheat grain were significantly affected by the tillage systems and fertilization rates (p  lt  0.001), as well as by the interaction of these two factors. A smaller dose of nitrogen fertilizer (60 kg ha(-1)) had a significantly better impact on the concentration of macro- and microelements in the wheat grain than the dose of 120 kg N ha(-1). The reduced tillage systems and lower nitrogen rates in nutrition had a better effect on the increase of the content of the studied elements in the wheat grain than the conventional cultivation which applied higher nitrogen rates.

AB  - The paper analyzes the possibility and the needs for the use of specific types of robots (mini unmanned aircraft with different designs and the designation of UAVs) and the possibility of using in agriculture (agrodrone). The year 2015 was proclaimed (Fortune Magazine, 2016) as the year of increasing and widespread use of UAVs in various areas of human activity, especially in agriculture and forestry (75% of use). This is important for large farm areas, where UAV has many useful functions and a very cost-effective commercial application. Today, the needs for UAVs have increased sharply with various opportunities for both civilian and military needs. There is also a significant interest in the development of new drones that can autonomously fly in different environments and locations and can perform various missions and tasks. Over the past decade, a wide range of applications for drones has gained the significance that led to the discovery of various types of unmanned UAVs of different sizes and weights. In this review, the classification of UAVs ranging based on a detailed overview of the development of the drone industry in recent years, this paper demonstrates the evolution of drones and differents application technologies. Of course, this development is very advanced and revolutionary, as well as the development of mobile and smart phones and the Internet, which will open the way for many users to participate in defining the future of UAV implementation.

AB  - U radu su analizirane mogućnosti i potrebe upotrebe specifičnih vrsta robota (mini bespilotnih letelica sa različitim dizajnom, o značane kao UAV) i način korištenja u poljoprivredi (agrodron). Časopis Fortune je 2015.godinu proglasio kao godinu sve većeg i široko rasprostranjene upotrbe UAV letelica, u različitim oblastima ljudske delatnosti, posebno u poljoprivredi i šumarstvu (75% upotrebe). Ovo je naročito važno za velike farme i oblasti pod šumama, gde UAV ima mnogo korisnih funkcija i veoma isplative komercijalne aplikacije. Danas, potrebe za UAV imaju nagli porast sa različitim mogućnostima kako za civilne tako i za vojne potrebe. Takođe postoji značajan interes za razvoj novih bespilotnih letelica koji mogu autonomno leteti u različitim okruženjima i lokacijama i obaviti različite misije i zadatke. Tokom protekle decenije XXI veka, širok spektar aplikacija za bespilotne letelice je dobio značaj koji je doveo do konstrukcija različitih tipova bespilotnih UAV, različitih veličina i težina i svakako namene. Naravno , tehnološki razvoj kod dron sistema je veoma tehničko -tehnološki napredan i revolucionaran, uz razvoj mobilnih i pametnih (android) telefona i interneta, brzo otvora puteve i mogućnosti za mnoge korisnike u definisanju nove budućnosti implementacije UAV različitim oblastima primene. Kompanija Livona d.o.o., Beograd i Institut za poljoprivrednu tehniku, Poljoprivredni fakultet u Beogradu, u tehničkoj saradnji imaju planove o implementaciji modela mikro drona EBee SK Livona RTK u narednim generalnim planovima za inspekciju, zaštitu i korišćenje poljoprivrednih zemljišta Republike Srbije, i posebno teritorije Opštine Stara Pazova (351 km2), gde je posebno mesto poljoprivrednog preduzeća Napredak a.d. VekomGeo d.o.o, Beograd u saradnji sa Institutom za poljoprivrednu tehniku Poljoprivrednog fakulteta u Beogradu ima planove o budućoj upotrebi drona model Aibot X6, za nadzor na površinama od 600 km2 (i poljoprivredna zemljišta) otvorenog kopa R.B. Kolubara ili drugih objekata. Institut za poljoprivrednu tehniku, Poljoprivredni fakultet u Beogradu, ima planove o saradnji sa opštino m Ub, zbog upotrebe modela mikro drona Hubsan H109S Ks4 PRO u inspekciji oko zaštite i načina korišćenja zemljišta i vo da na ovoj teritoriji (456 km2).

Časopis Fortune je 2015.godinu proglasio kao godinu sve većeg i široko rasprostranjene upotrbe UAV letelica, u različitim oblastima ljudske delatnosti, posebno u poljoprivredi i šumarstvu (75% upotrebe). Ovo je naročito važno za velike farme i oblasti pod šumama, gde UAV ima mnogo korisnih funkcija i veoma isplative komercijalne aplikacije. Danas, potrebe za UAV imaju nagli porast sa različitim mogućnostima kako za civilne tako i za vojne potrebe. Takođe postoji značajan interes za razvoj novih bespilotnih letelica koji mogu autonomno leteti u različitim okruženjima i lokacijama i obaviti različite misije i zadatke. Tokom protekle decenije XXI veka, širok spektar aplikacija za bespilotne letelice je dobio značaj koji je doveo do konstrukcija različitih tipova bespilotnih UAV, različitih veličina i težina i svakako namene. Naravno , tehnološki razvoj kod dron sistema je veoma tehničko -tehnološki napredan i revolucionaran, uz razvoj mobilnih i pametnih (android) telefona i interneta, brzo otvora puteve i mogućnosti za mnoge korisnike u definisanju nove budućnosti implementacije UAV različitim oblastima primene. Kompanija Livona d.o.o., Beograd i Institut za poljoprivrednu tehniku, Poljoprivredni fakultet u Beogradu, u tehničkoj saradnji imaju planove o implementaciji modela mikro drona EBee SK Livona RTK u narednim generalnim planovima za inspekciju, zaštitu i korišćenje poljoprivrednih zemljišta Republike Srbije, i posebno teritorije Opštine Stara Pazova (351 km2), gde je posebno mesto poljoprivrednog preduzeća Napredak a.d. VekomGeo d.o.o, Beograd u saradnji sa Institutom za poljoprivrednu tehniku Poljoprivrednog fakulteta u Beogradu ima planove o budućoj upotrebi drona model Aibot X6, za nadzor na površinama od 600 km2 (i poljoprivredna zemljišta) otvorenog kopa R.B.

AB  - The paper presents and analyzes the results of the exhaust emission measurement, depending on the tractor operating regime. The goal of this paper was to analyze the influence of the operating regime, that is, two different values of the engine crankshaft rotation speed and two different levels of transmission, to the exhaust emission level. In addition, the paper presents a brief overview of the technical solutions for the subsequent treatment of exhaust gases. The results shown allow comparison of the working regimes of the tested tractor models YTO X1204 and Foton 904. The research also shows how many operators with technical limitations on the tractor, knowledge and techniques of using the machine can contribute to a lower level of exhaust emissions (CO2, NO, NO2, NOX, SO2, O2) of built-in engines in tractors.

AB  - Spinach is very common in the human nutrition due to its high nutritive value. It is commonly grown in the greenhouses. In region of Serbia, spinach is commonly grown in the tunnel structure greenhouses, covered with single or double PE folia without additional heating. The aim of the research was to see if different greenhouse construction types influence the microclimatic parameters in the spinach production and to see if choosing the certain greenhouse construction type can improve an overall production conditions resulting in higher spinach yield, lower energy consumption and higher energy productivity. Spinach production was tracked in the three different types of greenhouses. The round-shaped greenhouse has its base diameter of 7 m while tunnel type greenhouse was 5.5 m wide and 24 m long. Single span greenhouse was 10 m wide and 50 m long. All greenhouses were covered with PE UV IR 180 mu m folia. Results show that production conditions are dependent on type of greenhouse construction. During the winter spinach production solar radiation energy losses in the tunnel structure were 29.38% while the round-shaped greenhouse was losing 19.51% of the solar radiation energy. Losses in the single-span greenhouse were 12% in the morning hours and 43% during the day. During the day air temperatures in the greenhouses were higher. In the round-shaped and tunnel structure greenhouse this temperature difference lower than 1 degrees C and are not considered important for the plants. In the case of single-span greenhouse inside-outside differences were 2.52 degrees C up to 16.26 degrees C.

AB  - Mineral fertilizers have a pivotal role in contemporary agricultural production, especially when seeking to exploit the full biological potential of crops. This paper presents the results of a three-year experiment on the distribution uniformity of different mineral fertilizer application systems. One of the objectives in this study was to define the physical and mechanical properties of four different types of mineral fertilizers and examine their changes during storage, transportation and application. A total of four fertilizers were taken into account: UREA, CAN, MAP and NP. The main physical properties, i.e. particle size, particle size distribution, friction coefficient, angle of repose and particle resistance, were analyzed on samples collected from the storage, the trailer (prior to application) and the field (after application). The results obtained show that fertilizers with a particle size distribution of 3.3 to 4.75 mm exhibit higher values of the angle of repose, friction and resistance. The lowest value of the angle of friction (17.53 0) was observed in the UREA fertilizer after application, whereas the highest angle of friction (24.37 0) was measured in the MAP fertilizer obtained from the storage. The values of the static repose angle varied depending on the fertilizer type and the place of sampling (storage, trailer or field). The lowest value of the static repose angle (30.34 0) was measured in the MAP fertilizer after application, whereas the highest static repose angle (36.91 0) was measured in the NP fertilizer from the storage. The NP fertilizer exhibited the highest value of the dynamic friction angle, whereas the lowest value of the dynamic friction angle was calculated for the UREA fertilizer. The NP fertilizer particles showed the highest resistance, whereas the UREA fertilizer particles were most susceptible to breakage.
AB  - Savremena poljoprivredna proizvodnja se ne može zamisliti bez primene đubriva, posebno sa aspekta boljeg korišćenja biološkog potencijala rodnosti gajenih biljaka. U radu je prikazan deo rezultata trogodišnjih ispitivanja tehničko-tehnološkog sistema aplikacije mineralnih đubriva različitim tipovima centrifugalnih rasipača. Jedan od ciljeva istraživanja bio je i određivanje fizičko-mehaničkih osobina različitih tipova mineralnih đubriva, njihovih promena tokom samog procesa aplikacije i njihovog uticaja na kvalitet same aplikacije. U istraživanje su uključena četiri tipa mineralnih đubriva i to UREA, KAN, MAP i NP. Dobijeni rezultati tokom ispitivanja fizičko-mehaničkih osobina primenjivanih mineralnih đubriva pokazuju da đubriva koja imaju najveći procenat granula prečnika između 3,3 mm i 4,75 mm imaju najveće uglove trenja i nasipanja, kao i dobru otpornost prema lomu granule. Vrednosti ugla trenja su značajno varirale u zavisnosti od tipa đubriva i mesta uzorkovanja. Najniža vrednost, 17,53o je zabeležena kod UREE nakon aplikacije a najviša, 24,37o kod đubriva MAP iz skladišta na imanju. Vrednosti statičkog ugla nasipanja su takođe statistički značajno varirale u zavisnosti od tipa đubriva i mesta uzorkovanja. Najniža vrednost, 30,34o, je zabeležena kod đubriva MAP nakon aplikacije a najviša, 36,91o, je zabeležena kod NP đubirva iz skladišta. NP đubrivo je pokazalo i najviše vrednosti dinamičkog ulga trenja. Najniže vrednosti ovog parametra, 23,35o, imalo je đubrivo UREA. Čvrstoća granula je varirala u zavisnosti od tipa đubriva i od mesta uzorkovanja. Najviše vrednosti su zabeležene kod đubriva NP u svim fazama manipulacije dok su najniže vrednosti zabeležene kod đubriva UREA.

AB  - This research aimed to determine the effects of different cover crops and application of bio-fertilizer on dynamic of nitrogen in the soil and sweet maize yield. Also, we evaluated the effect of fall-winter species (common vetch, field pea, winter oats, fodder kale) and a mixture of vetch and field pea with oats used as cover crops, as such as dead organic mulch and traditional variant, without coverage on biomass, chlorophyll and protein content in leaves and grain of main crop. Biomass production and N uptake by cover crops ranged from 4.25 to 90.20 kg ha(-1) and from 0.34 to 133.80 kg ha(-1) N, respectively, depending on cover crop type. At harvest soil nitrate content in treatments with cover crops was 50-90% lower than in the control, reducing spring N leaching risk. Residual mineral N significantly increased with application of microbiological fertilizer. The chlorophyll content of the main crop was significantly lower in treatments without cover crops. Consequently, sweet maize yield was the highest in fodder kale and field pea (7263.83 and 7177.27 kg ha(-1)) treatments, but the smallest in winter oat and common vetch (6802.47 and 6184.14 kg ha(-1)). In terms of all investigated traits, particularly grain yield, cover crops and microbiological fertilizer expressed more efficiency in the dry year. It could be concluded that N content should be controlled effectively by sowing main crops after planting of cover crops in biological farming systems in a semiarid region.

AB  - Agricultural production in greenhouse represents the most intensive form of agricultural production. This is a very complex production system that needs to be well maintained and with great attention. The aim of this paper is to present preliminary research results on raspberry production in greenhouse and in the open field regarding the microclimatic production conditions. In this paper, results on microclimatic production conditions in the tunnel structure greenhouse and in the open filed are presented. The raspberry variety Heritage (Rubus Heritage) was grown in the 7 x 24 m tunnel greenhouse covered with the single PE folia and in the open filed. Results show that production conditions in the greenhouse enable prolonged harvesting (September, October) till the first frosts. Air temperature, air relative humidity and solar radiation were measured and analyzed. Temperature inside the greenhouse varied along the greenhouse and during the day but the variations were not significant enabling the uniform production conditions during the day. Air relative humidity did not show significant variation concerning the open field and greenhouse production. Solar radiation showed high losses in the morning hours. Only 25.82 % of solar energy was available to the plants.

AB  - Contemporary agricultural production has high demands in sense of high productivity technical and production systems and thus imposes construction of new highly sophisticated technical solutions. One of these new solutions for the energy and economy efficient agricultural production is CASE STEIGER 400 tractor. The aim of the research was to determine the overall tractor working parameters and their optimization in tillage using a chisel plough. Obtained results show that the average fuel consumption during the field experiments was 38.8 l/ha, productivity 2.4 ha/h and energy consumption 68.6 kWh/ha. In the case of non-conventional tillage overall energy consumption was 250 MJ/ha, indicating that energy savings are feasible if adequate production technology is applied and technical systems used.

AB  - The biggest problem in seed birdsfoot trefoil harvest is pod cracking before and during harvest. At full maturity, birdsfoot trefoil pods crack easily, resulting in seed spillage and hence seed losses. The cracking pod problem significantly limits the successful production of seeds. Exploitation indices, operational performance and reliability of a used general-purpose Claas Mercator 50 combine harvester in harvesting birdsfoot trefoil seed were studied. The testing was carried out in field conditions in Western Serbia area. The losses of grain over the cutter bar and over the threshing machine were found out.Total header and thresher losses ranged from 21.28% to 23.86% at an operating speed of 2.04 km/h and 2.63 km/h, respectively. This is an expected result for the crop under increased crop moisture conditions. There was loss of operating time i.e. congestion of unharvested grain due to increased operating rate, seed moisture and straw. Time consumption for elimination of harvesting delay at a rate of 2.63 km/h was higher than at a rate of 2.04 km/h and accounted for 13.48% of the total operating time. The research also involved monitoring of intensity pod cracking during the day depending on air temperature. Birdsfoot trefoil pod opening intensity increased of starts after 11 a.m. at air temperatures over 30 0 C when 80-90% of pods crack at 17- 20% moisture.
AB  - U žetvi semena žutog zvezdana najveći problem predstavlja otvaranje mahuna pre i toku žetve. U punoj zrelosti mahune žutog zvezdana lako se otvaraju i seme se prosipa što dovodi do gubitaka. Problem otvaranja mahuna u značajnoj meri limitira uspešnu proizvodnju semena. Istraživani su eksplatacioni pokazatelji, kvalitet rada i pouzdanost starog univerzalnog žitnog kombajna 'Claas Mercator 50' u žetvi semena žutog zvezdana. Ispitivanje je obavljeno u poljskim uslovima Zapadne Sbije. Ustanovljeni su gubici na hederu i vršalici kombajna. Ukupni gubici hedera i vršalice na ispitivanom kombajnu iznosili su od 21,28% do 23,86% pri radnim brzinama 2,04 km/h i 2,63 km/h, što se moglo i očekivati za pomenuti kombajn i ovu kulturu u uslovima povećane vlažnosti useva. Tokom rada kombajna dolazilo je do zastoja tj. zagušenja vršidbene mase, usled povećane radna brzina, vlažnosti semena i slame. Utrošeno vreme za otklanjanje tehnoloških zastoja kod radne brzine od 2,63 km/h bilo je veće nego kod brzine od 2,04 km/h i iznosilo je 13,48% od ukupnog radnog vremena. Intenzitet pucanja u toku dana zavisno od temperature je takođe bio predmet ispitivanja ovog rada. Povećani intenzitet otvaranja mahuna počinje posle 11 sati, pri temperaturi vaduha preko 30 0 C kada se otvori 80-90% mahuna vlažnosti od 17- 20%.

AB  - Greenhouse plant production is one of the most intensive parts of the agricultural production. In order to reduce the costs and save the energy, various greenhouse constructions and different coverings are offered to the farmers. One of the biggest problems is in winter production when additional heating and light are needed as well as in summer when intensive cooling is needed. During these period construction and coverings fully show their qualities. The aim of this research was to investigate the temperature and air relative humidity distribution in the different greenhouse constructions in the different production systems in order to see if the choice of the greenhouse construction can improve the production conditions inside the greenhouse enabling the better energy efficiency and lower energy input for heating / cooling. Results show that temperature pattern and its values during the night and day depends on the greenhouse construction, plant specie that is grown and production season. Temperature differences of 6.91 degrees C in the tunnel construction during winter were found to be very significant while in the gutter-connected greenhouse these differences were not significant. In the summer period temperature differences were not significant in neither of the greenhouses. In the winter production gutter-connected greenhouse had significantly, 5.09 degrees C, higher temperatures compared to the outside during the day and during the night. In the tunnel greenhouse these temperatures were significantly higher only during the day. Air relative humidity showed significantly higher values for the summer and winter period. In the gutter-connected greenhouse these differences were higher only in the summer period.

Energy consumption in irrigation and energy output through yield were analyzes for three different irrigation systems (self-propelled rain wing, self-propelled rain gun and linear system) in order to establish the optimal exploitation and energy parameters of the given irrigation systems. Results show that, concerning the depth of irrigation, good results can be obtained with the lower depths (0-30 cm). Concerning the irrigation application rate it was concluded that with the lower application rate and higher number of irrigation cycles better water usage can be obtained. Energy consumption of the mobile irrigation systems shows that the optimal relation of the energy output (yield energy) and energy input through the irrigation process in case of mobile rain wing is the lowest (12.29) and that with mobile linear device highest (288.19). Energy consumption in tillage and sowing in the system of conventional tillage was 2519.31 MJ/ha. Energy of irrigation varied depending on type of irrigation system. With the mobile linear system energy consumption was 814.35 MJ/ha, with mobile irrigation wing 1338.54 MJ/ha and with the self-propelled rain gun 8041.17 MJ/ha.

AB  - The main purpose of man's activities in crop production is to provide such a final product which will, by its quality and quantity, meet the basic principles of cost-effective and cost-efficient production. High yields are leaving soli with the lower productivity and with much worse physical and mechanical properties. In this sense, application of fertilizers is of a great importance. The aim of this study was to demonstrate how much the uniformity of distribution depends of the applied fertilizers physical-mechanical properties and technical system of application. The paper gives the results of two centrifugal spreaders working quality in relation to physical and mechanical properties of applied fertilizers. Variation coefficients showed that no good uniformity was achieved. Real application varied significantly along the swath having the oscillations from 82% lower to 56% higher than the nominal application rate.

AB  - Computer assisted image analysis offers many important (pseudo) man-independent procedures, which can be used in combination with classical evaluation methods. This paper presents a novel approach in fruit surface quality analysis. It includes a computer program, based on contour recognition and decomposition of digital image objects according to their color scale intensity. This analysis has been performed by digital pattern recognition method (DPR), which is based on automatic color scale and object analysis of isohels contours for isolated and separated objects. As a result of this analysis, a more precise grading of the fruit surface quality can be achieved.

AB  - The quality of service of agricultural machinery represents one of the basic factors for successful agricultural production. In this sense, there is a clear need for defining the exact indicator of the quality of these machines, according to which it could be possible to determine which machine is optimal for different working conditions. The concept of effectiveness represents one of synthesis indicators of the quality of service of the technical systems. In this paper the effectiveness is defined using the fuzzy set theory, and reliability, maintainability and functionality are used as influence indicators of the effectiveness. In that sense the model for assessing the effectiveness of tractor as a typical representative of agro machinery has been formed. The model is based on integration of linguistic description of the above mentioned influence indicators using fuzzy set theory and max-min composition. The model was tested on the example of three tractors of the same category, which are exploited in climatic and soil conditions in the wider Belgrade (Serbia) area. Even if the conditions in this experiment were approximately equal, the difference of the achieved effects was attained and very significant, compared to other operation parameters.

AB  - In order to have a good visual inspection of the foliage surface coverage quality after the use of filed sprayer, water-sensible papers can be used. Surface coverage, droplet distribution and solution incorporation into the plant canopy beside the sprayer itself depend on the plant canopy characteristics (number of trees, their development stage, shape of the foliage), weather conditions during the application etc. The aim of this paper was to give the results of testing the three nozzle types (standard, anti-drift and injection) in the different working regimes of the filed sprayer in order to obtain the optimal foliage surface coverage. With the use of currently available filed sprayers, the application rate can't be lower than 200 l/ha. Sprayers with the air induction nozzles have a significant advantage concerning the fact that they can operate in windy conditions (8 m/s) with the operating pressure of 8 bar but they are still not universal for all working conditions.
