AB  - The work investigated the equipment of tractors, attachments and combines
in a medium-sized family farm. The research was conducted on the registered family
farm "Đurković" in the village of Čestin in the municipality of Knić. The farm cultivates
arable and forage crops for feeding dairy cows and fattening oxen on an area of 44 ha.
In the sowing structure, meadows are the most represented with 20 ha (45.45%),
alfalfa 5 ha (11.36%), silage maize 3 ha (6.83%) and perko 0.4 ha (0.91%). The farm
also grows barley on 2 ha, wheat on 1.5 ha, soybeans on 0.7 ha, oats on 0.4 ha, and
peppers for processing on 40 ares. The production process is carried out with three
tractors, 22 implements, a self-propelled combine for small grains and a combine for
silage. One tractor with an average engine power of 41.4 kV works 14.67 ha of
available land with 7.33 attachments. The total available power of the tractor engine is
129.43 kW, and the energy equipment of the farm is 2.94 kW/ha, which is the average
of family farms in Serbia. If the combine engine power for small grain and silage were
added, the energy equipment would increase to 7.85 kV/ha. Combines are underutilized
because they are used only for subsistence. The average age of mechanization is over
40 years, so replacement and purchase of new agricultural machinery is not possible.

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  - 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.

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.

AB  - The productivity traits of rye, khorasan wheat and quinoa on degraded soil were investigated in a three-year research (2010-2012). The research was carried out in two localities: Stanari (ST) (Bosnia-Herzegovina) and at "TENT 2" in Obrenovac (OB) (Serbia). A significant interdependence between grain yield and aboveground biomass yield was observed in the investigated genotypes and localities. The resulting average grain yields in these localities ranged between 1,166-1,702 kg ha-1 (rye), 1,826-1,943 kg ha-1 (khorasan wheat) and 520-966 kg ha-1 (quinoa). Fluctuations in grain yields were due to different soil conditions different nutrient contents and the distribution of precipitation at initial stages of crop development. This research confirmed that rye is a crop with minimum soil requirements and it can be successfully grown in poor soil. The second best biomass yield was obtained by khorasan wheat, while the lowest biomass yield was obtained by quinoa.

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.
