AB  - For the establishment and exploitation of alfalfa, the seed must be of high purity, germination, and high genetic value. Most of these requirements is realized through processing or removal of foreign matter and seeds of lower quality. Alfalfa seed processing comprises a number of operations from which the most significant are: cleaning, packaging into ambalage, labeling, storage, disinfection and disinsection. In combine harvesting of alfalfa seeds, the obtained material is a mixture of seed of grown plant, seeds of other plants-cultivated and weed, and various impurities of organic and inorganic origin. The task is to remove all foreign matter and various impurities from the natural seed and extract pure grain of primary culture. The importance of processed seed is reflected in the fact that the seed must be prepared for sowing in the most favorable condition, quality and germination. In this study natural alfalfa seed was processed on three different equipment. The aim of this research was to determine relevant parameters of all tested equipment for alfalfa seed processing. Relevant parameters that define the characteristics of equipment for seed processing were: pure seed (%), weed seeds and seeds of other crops (%), inert matter (%), the quantity of processed seed (kg), seed processing time (h), consumption of active energy (kWh) and reactive energy (kVArh), seed losses (%) and output (%). Testing was conducted at the processing center of the Institute of Forage Crops in Globoder-Kruševac, with three replications. Natural alfalfa seed with purity of 78.0%, with an extremely high content of quarantine dodder weed (Cuscuta spp.), was processed. Based on these results it is possible to select an appropriate equipment and optimize and rationalize the alfalfa seed processing.
AB  - Za zasnivanje i eksploataciju lucerke, seme mora biti visoke čistoće, klijavosti, kao i visoke genetske vrednosti. Veći deo ovih zahteva se ostvaruje kroz doradu, odnosno odstranjivanjem nečistoća i semena lošijeg kvaliteta. Dorada semena lucerke obuhvata veći broj operacija od kojih su najznačajnije: prečišćavanje, pakovanje u ambalažu, deklarisanje, skladištenje, dezinfekcija i dezinsekcija. Pri kombajniranju semenske lucerke materijal koji se dobija predstavlja mešavinu semena gajene biljke, semena drugih biljaka- kulturnih i korovskih, kao i razne nečistoće organskog i neorganskog porekla. Zadatak čišćenja je da se iz ovako dobijenog naturalnog semena sa primesama uklone sva zrna stranih primesa i razne nečistoće i izdvoji čisto zrno osnovne kulture. Značaj dorađenog semena se ogleda u tome da se seme blagovremeno pripremi u što povoljnije stanje za sejalicu i kvalitetnu setvu, klijanje i nicanje. U radu su prikazani rezultati ispitivanja naturalnog semena lucerke pri doradi na tri različita sistema mašina. Cilj ispitivanja bio je da se pri doradi semena lucerke odrede relevantni parametri za svaki sistem mašina. Relevantni parametri koji definišu karakteristike svakog sistema mašina za doradu semena bili su: čisto seme (%), seme korova i seme drugih kultura (%), inertne materije (%), količina dorađenog semena (kg), vreme dorade semena (h), utrošak aktivne električne energije (kWh) i reaktivne električne energije (kVArh), gubici semena (%) i randman dorade (%). Ispitivanje je obavljeno u doradnom centru Instituta za krmno bilje u Globoderu-Kruševcu, pri čemu je u tri ponavljanja dorađivano naturalno seme obične lucerke čistoće 78.0% sa ekstremno visokim sadržajem karantinskog korova viline kosice (Cuscuta spp.). Na osnovu dobijenih rezultata moguće je izvršiti izbor odgovarajućeg sistema mašina za doradu semena lucerke, odnosno optimizaciju i racionalizaciju u procesu njene dorade.

AB  - Importance of the irrigation does not to be explained much since water is one of the crucial parameter of life development and preservation on Earth. Development of irrigation technology and technique and their introduction in to practice represents a very important investment for every farmer. In this paper a part of mobile raining irrigation systems testing in crop and vegetable production is presented. The aim of the paper was to analyze the distribution uniformity and energy parameters of the mobile wheel line sprinkler system. Based on these parameters it is possible to optimize the system in sense of energy, ecology and economy. The system was tested in conditions of vegetable and crop production. The results show that energy consumption was 62.02 kWh/ha and productivity 0.55 ha/h. The system also showed uneven distribution and high difference compared to nominal rate. The nominal value of the irrigation rate was 15 mm but system achieved, in average, 13.12 mm.

AB  - Greenhouse production is still among the most energy-consuming branches of agriculture. Producers are faced with high cost of the operations involved in greenhouse production processes (climate control, fertilizing, irrigation). This is the reason why an optimal combination of energy inputs that will make this production more energy efficient, needs to be found. In this paper the influence of the production technology and greenhouse construction on energy efficiency in winter lettuce production was estimated for different double plastic covered greenhouses in Serbia region. In order to see whether the greenhouse structure influences energy consumption, energy inputs were estimated for lettuce production in the open filed and in four different greenhouse structures (a tunnel and gutter connected structure and two multi-span greenhouses). On the basis of lettuce production output and the energy input, specific energy input, energy output-input ratio and energy productivity were estimated. Results show that the lowest energy consumption was obtained for gutter connected greenhouse with two bays, 3.11 MJ/m2. The highest energy consumption was measured for the open filed lettuce production, 7.99 MJ/m2. The lowest lettuce yield was measured in the open filed production (1.89 kg/m2) and the highest in the multi-span greenhouse, GH4, (6.08 kg/m2). The highest value for output-input ratio was calculated for the multi-span greenhouse with thirteen bays, 0.85 and the lowest for the open filed production, 0.11. Regression equations show the nature of the greenhouse structure influence on these parameters.
AB  - Biljna proizvodnja u zaštićenom prostoru predstavlja granu poljoprivrede sa najvećom potrošnjom energije. Proizvođači su suočeni sa visokim troškovima pojedinih proizvodnih procesa, što predstavlja jedan od razloga potrebe pronalaženja optimalne kombinacije energetskih inputa koja bi ovu proizvodnju učinila energetski efikasnijom. U ovom radu analiziran je energetski bilans proizvodnje salate na otvorenom polju i u objektima zaštićenog prostora različite konstrukcije. Utrošak energije praćen je u proizvodnji na otvorenom i u četiri tipa objekata zaštićenog prostora. Na bazi direktnih i indirektnih energetskih inputa i energetskog outputa određeni su specifični energetski input, energetski odnos i energetska produktivnost. Rezultati pokazuju da je najniža potrošnja energije po jedinici površine ostvarena u blok objektu sa dva bloka, 3,11 MJ/m2, dok je najviša vrednost utrošene energije zabeležena u proizvodnji na otvorenom polju, 7,99 MJ/m2. Najniži prinos ostvaren je u proizvodnji salate na otvorenom polju, 1,89 kg/m2, dok je najviši prinos ostvaren u blok objektu GH4, od 6,08 kg/m2.

AB  - In this paper the influence of greenhouse construction on energy efficiency in winter lettuce production was estimated fir different double plastic covered greenhouses in Serbia region. In order to see whether the greenhouse structure influences energy consumption, energy inputs were estimated for lettuce production in four different greenhouse structures (a tunnel and gutter connected structure and three multi-span greenhouses). On the basis of lettuce production output and the energy input specific energy input, energy output-input ratio and energy productivity were estimated. Results show that the lowest energy consumption was obtained for gutter connected greenhouse with two bays, 3.11 MJ/m(2). The highest energy consumption was multi-span greenhouse with thirteen bays, 3.30 MJ/m(2). The highest value for output-input ratio was calculated for the multi-span greenhouse with thirteen bap, 0.85 and the lowest for the tunnel structure, 0.47. Regression equations show the nature of the greenhouse structure influence on these parameters.

AB  - Tillage exposes the soil to different mechanisms of mechanical decomposition, which crucially change its structure. Possible approach in controlling the quality of each specified operation and complete tillage process assumes establishing the functional relations between the operational parameters of applied mechanization and resulting mass probability density function of soil particle sizes. Based on experimental data from three independent experiments, the appropriate nonlinear relationships between the mass probability density functions of different soil fractions and particle diameters of these fractions. Calculations are based on the least squares fitting method. These expressions can facilitate modeling and prediction of soil fractions distribution and tillage quality control.
AB  - Mehanizovana obrada izlaže zemljište uticaju različitih mehanizama mehaničke dekompozicije, suštinski menjajući njegovu strukturu.

AB  - In the process of alfalfa seed processing, all relevant parameters are directly dependant on presence of weed species and other impurities in natural seed, as well as on the equipment used. The higher amount of weed in natural alfalfa seed lowers the total amount of processed seed, making the processing harder and more expensive. In alfalfa crop, quarantine weeds are especially harmful, such as dodder (Cuscuta spp.) and curly dock (Rumex spp.). One of the greatest problems in alfalfa planting is the presence of harmful parasitic flowering plant dodder (Cuscuta spp.) which is typical weed - alfalfa parasite that lowers hay and seed production. The paper shows the results of the analysis of influence different weed content from two lots of natural alfalfa seed (I, II) of different purity, on the relevant processing parameters. Processing of the both lots of seed was done on the same equipment. The relevant parameters that define alfalfa seed processing effects were: pure seed (%), weed seeds and seeds of other cultures (%), inert matters (%), seed processing time (h), consumption of active (kWh) and reactive power (kVArh), processed seed quantity (kg), metal powder (kg) and water (l) consumption, processing output (%) and seed losses (%).
AB  - U procesu dorade semena lucerke svi relevantni parametri dorade direktno zavise od zastupljenosti korovskih vrsta i ostalih primesa u naturalnom semenu, kao i od sistema mašina koji se koristi za doradu. Veći sadržaj štetnih korova u naturalnom semenu lucerke smanjuje ukupnu količinu dorađenog semena, otežava i poskupljuje doradu. U usevu lucerke posebno su štetni karantinski korovi, vilina kosica (Cuscuta spp.) i štavelj (Rumex spp.). Jedan od najvećih problema u gajenju lucerke je prisustvo štetne parazitske cvetnice viline kosice (Cuscuta spp.) koja je tipičan korov - parazit lucerke koji smanjuje proizvodnju sena i semena.

Dorada obe partije semena obavljala se na istom sistemu mašina. Relevantni parametri koji definišu efekte dorade semena lucerke bili su: čisto seme (%), seme korova i seme drugih kultura (%), inertne materije (%), vreme dorade semena (h), utrošak aktivne (kWh) i reaktivne električne energije (kVArh), količina dorađenog semena (kg), utrošak metalnog praha (kg) i vode (l), randman dorade (%) i gubici semena (%).

AB  - In order to save and rationally use energy, the usage of heat pumps is getting ever more attention. Producers and distributors of heat pump systems have accumulated certain experience when it comes to using them for individual house heat supply, mainly in the form of floor heating. However, it is possible to use the heat energy obtained by a heat pump for different processes within agricultural production, including the heating of protected spaces for piglets (sucklings and weaned). Research results have established that different exploitation conditions in dwelling houses and live-stock premises demand careful estimation of heat pump type to be used in the pigsty. The more essential factor effecting the heat pump operation is the temperature of the heating surface, which for the floor heating in general, ranges between 25-30°C, but in the case of piglets and concrete floor panels, this temperature should range between 35-40°C. To increase the efficiency rate of heat pump, of particular interest is the microclimate control in livestock husbandry buildings. For that purpose, specially important is the usage of wet scrubber systems for air purification with low pressure drop. Besides the possibility of reducing the risk of microorganisms, organic and mineral dust, in interaction with heat pump, it is also possible to significantly increase energy saving, and improve the technological process output by increasing the quality of basic product and environment protection.

AB  - The aim of this paper is to analyze energy patterns in open and greenhouse tomato production, since tomato is very important vegetable in human nutrition with tendency to be used whole year. The greenhouses used were one tunnel structure, covered with double PE folia, 5 x 20 m and one gutter-connected double PE covered structure 21m wide and 250m long. The results obtained lead to the conclusion that lower specific energy per production surface can be expected in conditions of the open filed and that, regarding the greenhouses lower value for energy consumption can be expected in case of multi-span greenhouses. The results show that there are differences in yield as well as in energy consumption between the open and the greenhouse tomato production. The highest yield was measured in the gutter-connected greenhouse, 23.78 kg/m2 and lowest in the open filed, 17 kg/m2. The direct and the indirect energy input measured show that the lower specific energy consumption per production surface can be expected in the open filed compared to the greenhouse tomato production. The lowest energy input per kilogram of product was measured for the gutter-connected greenhouse, of 0.89 MJ/kg, and the highest for the tunnel structure, 1.21 MJ/kg. The highest energy productivity was measured for the gutterconnected structure, 1.12 kg/MJ and the lowest for the tunnel structure, 0.83 MJ/kg. Based on the energy consumption and the energy output it can be seen that the tomato production in the open filed is less energy demanding compared to the tomato production in the greenhouses. The structure of energy inputs shows that 80 up to 90% of the total energy consumption is based on indirect energy inputs, mostly fertilizers, human labor and water for irrigation. Results also show that energy consumption must be analyzed together with the energy output. Greenhouse structures had better ratio between yield and energy consumption compared to the open filed production system. This has also led to the higher energy productivity in the greenhouse tomato production systems.
AB  - S obzirom na intenzivnost korišćenja paradajza u ljudskoj ishrani, za proizvođače je od izuzetnog značaja energetska, ekonomska i ekološka efikasnost proizvodnje.S obzirom na to da se paradajz gaji kako na otvorenom tako i u objektima zaštićenog prostora cilj istraživanja je bio analiza proizvodnje na otvorenom polju i u objektima zaštićenog prostora tunel i blok tipa s aspekta potrošnje energije i energetske efikasnosti. Objekat tunel tipa dimenzija je 5 x 20 m i pokriven je dvostrukom 180 μm PE UV IR folijom. Blok objekat je sa dva broda, dimenzija 21 x 250 m pokriven dvostrukom PE UV IR folijom. Rezultati ukazuju na razlike kako u prinosu tako i u potrošnji energije i energetskoj efikasnosti u proizvodnji na otvorenom i u objektima zaštićenog prostora. Najviši prinos ostvaren je u blok objektu od 23,78 kg/m2 a najniži na otvorenom polju od 17 kg/m2. Izmereni utrošak materijala i ljudskog rada u vidu direktnih i indirektnih inputa ukazuje da se niža potrošnja energije po jedinici površine može očekivati na otvorenom, a da se, kada su objekti zaštićenog prostora u pitanju niža potrošnja energije može očekivati kod objekata veće specifične zapremine, tj. objekata blok tipa. Najniži energetski input po kilogramu proizvoda ostvaren je u blok plasteniku, 0,89 MJ/kg, a najviši u objektu tunel tipa, 1,21 MJ/kg. Kada se govori o energetskoj produktivnosti u blok objektu je utvrđena najviša vrednost od 1,12 kg/MJ, dok je u objektu tunel tipa bila najniža i iznosila je 0,83 kg/MJ.

AB  - In this paper the influence of greenhouse construction on energy efficiency in winter lettuce production was estimated for different double plastic covered greenhouses in Serbia region. In order to see whether the greenhouse structure influences energy consumption, energy inputs were estimated for lettuce production in four different greenhouse structures (a tunnel and gutter connected structure and three multi-span greenhouses). On the basis of lettuce production output and the energy input, specific energy input, energy output-input ratio and energy productivity were estimated. Results show that the lowest energy consumption was obtained for gutter connected greenhouse with two bays, 3.11 MJ/m2. The highest energy consumption was multi-span greenhouse with thirteen bays, 3.30 MJ/m2. The highest value for output-input ratio was calculated for the multi-span greenhouse with thirteen bays, 0.85 and the lowest for the tunnel structure, 0.47. Regression equations show the nature of the greenhouse structure influence on these parameters.

AB  - The aim of this paper is to analyze energy patterns in open and greenhouse tomato production, since tomato is very important vegetable in human nutrition with tendency to be used whole year. Concerning the high energy consumption in greenhouse production a comparison with open filed tomato production was found to be interesting. Data used in the study were obtained from the experiment carried out on a private property 140 km south from Belgrade. In the study, energy values were calculated by multiplying the amount of inputs and outputs by the related energy conversion factors. The same tomato varieties were planted in open filed and in the greenhouse at the same time. The greenhouse used was gutter-connected double PE covered structure 21 m wide and 250 m long. According to energy output (yield per m2) parameters for estimating tomato production energy efficiency were calculated (energy input per kg of product, energy out/in ratio and energy productivity).

Paradajz je gajen na otvorenom polju i u dvobrodnom plasteniku pokrivenom dvostrukom PE folijom, dužine 250 m i širine 21 m. Na osnovu energetskih inputa i ostvarenog energetskog outputa utvrđene su energetska efikasnost, specifični energetski input i energetska produktivnost za oba tehnološko-tehnička sistema proizvodnje.

AB  - Proper choice and efficient utilization of various technological-technical application systems still has a significant importance concerning ecology, energy and economy in agriculture. Due to the predominant practice of using granulated mineral fertilizers an analysis of mineral fertilizer processing including its production, manipulation and application was made. Physical and mechanical characteristics of mineral fertilizers and fertilizer reaction with the application systems are of outmost importance in fertilizer application system choice. Successful utilization of mineral fertilizers predominantly depends upon the interaction between mineral fertilizers physical-mechanical characteristics and the appropriate type of spreader.

AB  - This research has included two different raining irrigation systems, both rain gun and mobile linear system. According to the calculations, can be concluded that those two systems work with different pressures, which causes different losses in the pipe line. Reason for significantly higher losses (1,7 bar) and consequently higher energy consumption (131 kW/ha) at self propelled rain gun is that water energy in this case is used for rolling the hose and movement of the sprinkler. At mobile linear system, the movement is propelled by electro motors and, at the same time, this system works with significantly lower pressures, which means lower energy consumption, as well (45,28 kW/ha).
AB  - Istraživanjima su obuhvaćena dva različita sistema navodnjavanja kišenjem i to samohodni kišni top i mobilni linearni sistem. Na osnovu proračuna može se zaključiti da ova dva sistema rade sa različitim pritiscima, a samim time i gubitci u cevovodu su različiti. Razlog znatno većim gubicima (1,7 bar), a time i većoj potrošnji energije (131 kW/ha) kod samohodnog kišnog topa leži u činjenici da se energija vode u ovom slučaju koristi za namotavanje creva odnosno za kretanje prskača. Kod mobilnog linearnog sistema za kretanje se koriste elektro motori, a sem toga ovaj sistem radi sa znatno nižim pritiscima pa je samim time i potrošnja energije manja (45,28 kW/ha).

abstract = "This research has included two different raining irrigation systems, both rain gun and mobile linear system. According to the calculations, can be concluded that those two systems work with different pressures, which causes different losses in the pipe line. Reason for significantly higher losses (1,7 bar) and consequently higher energy consumption (131 kW/ha) at self propelled rain gun is that water energy in this case is used for rolling the hose and movement of the sprinkler.
