AB  - Increasing the production efficiency of family farms is one of the main drivers of economic growth and a prerequisite for their further development. Family farms that use productive resources more efficiently over time are in a position to invest more in the family farm and to grow regardless of their initial size and the challenges they face. Consequently, there is a need to find economically efficient models of crop production on family farms, which was the main goal of this research.  Data collected by detailed surveying of 100 holders of selected family farms were used as the basic source for conducting this research. The collected data refer to the production years of 2011/2012, 2012/2013, 2013/2014, 2014/2015 and 2015/2016.  The choice of methods used in the research was determined by the defined subject of research and set goals, on the one hand, and by the volume and quality of the available data, on the other hand. In this regard, in order to measure the efficiency of crop production on surveyed family farms, in practice, it is often necessary to consider multiple outputs and inputs that are by their nature heterogeneous and expressed in different units of measure. Therefore, it was necessary to define such an efficiency measure that would take into account all the significant results of crop production and all productive resources used for their realisation. This implies an analysis of the efficiency using the method of mathematical programming such as Data Envelopment Analysis (DEA). The obtained solutions have special economic interpretations and based on them the information important for managing the further business of both efficient and inefficient surveyed family farms was obtained.  Finally, a comparative analysis of the economic efficiency of different models of crop production on family farms was carried out, aimed at determining whether there were any statistically significant differences between the average economic efficiencies of different models. To examine the existence of differences in the economic efficiency among different models, the Kruskal-Wallis test was conducted...

AB  - The paper deals with the subsequently effect of ameliorative tillage on the dynamics of some important physical soil properties in winter wheat. The trial was carried-out at the experimental fields of Maize Research Institute 'Zemun Polje' Krnjesevci near Belgrade on meadows chernozem soil type. The folowing ameliorative and conventional tillage systems were included in ivestigations: 1. Ameliorative tillage system - (ATS) - includes new types machines for field systematization-scrapers (USM 5) in autumn, drainage plow on the depth 60-80 cm, and subsoil with heavy vibratory subsoiler VR 5. on 30-35cm depth. After basic tillage we prepared soil for seeding with preparation by disking and harrowing 2. Control variant - conventional tillage without ameliorative measures In 2008.yr previous crop were maize and sunflower after that ameliorative measures. Second crop in 2009/2010 were winter wheat. The following soil properties were studied: bulk density, total porosity, moisture weight and volume percent, and total water content in different layers in m3, in tillering and heading stage of winter wheat on the different depth 0-10; 10-10; 20-30. Ameliorative tillage systems had subsequently effects for all investigated soil properties on this heavy soil type compared with control.

U ispitivanju smo imali dve varijante: 1. Sistem meliorativne obrade zemljišta (ravnanje + rad krtičnog pluga + podrivanje + predsetvena obrada zemljišta). 2. - Kontrolu sa konvencionalnom obradom zemljišta (oranje raonični plugom + predsetvena obrada zemljišta). U drugoj godini posle izvedenih mera u zasejanom usevu ozime pšenice pratili smo dinamiku fizičkih osobina zemljišta u fazi bokorenja i klasanju. Dobijeni rezultati obrađeni su statistički analizom varijanse i pokazali su da postoje brojne statistički signifikantne razlike u sa povoljnijim fizičkim osobina na meliorisanom zemljištu u poređenju sa kontrolnom varijantom. Gornji delovi orničnog sloja su rastresitiji na meliorisanoj varijanti tako da su u stanju da prihvate lakše veće količine vode i što je važno da je brže sprovedu u dublje slojeve. Ove činjenice pokazuju da meliorativne mere imaju produžno dejstvo koje se oseća i u narednim godinama.

AB  - In this paper influence of two tillage systems for soils of heavy mechanical composition (conventional with bottom plough and ameliorative tillage system) is analyzed. The emphasis of research, in addition to other secondary effects, is focused on the yield and the cost of production of main field crops as relevant indicators of efficiency of plant production. Production of field crops with conventional tillage system gave satisfactory yields, characteristic for a given agro-climatic conditions (quantity and distribution of rainfall, soils of heavy mechanical composition). Ameliorative tillage system of soils of heavy mechanical composition in comparison to conventional system achieved significantly higher yields of crops in dry years (8.6% sunflower, 9.9% corn), and even more in years with a lot of rainfall (21% wheat ). The research is necessary to continue in order to see the effects of ameliorative tillage system on other breeding plants, and also for observing the effects of continuous usage of this tillage system (in second, third and fourth year of production).

AB  - This paper presents the results of the application of the machines and tools for new technologies in plant production for two years of research. The comparative analysis of the influence of new technologies and new types of machines was done, and also the effect of conventional tillage systems on several agricultural crops (sunflower, commercial maize and wheat). During the experiment, we analyzed the effects of application of new line of machines to: physical properties of soil, morphological features of crops, use of energy and yield, and we also analyzed the economic aspects of the application. On the control plots, a conventional tillage system was simultaneously applied for comparative analysis of the previously mentioned factors. Trials were conducted on production plots of Maize Research Institute 'Zemun Polje' in Krnješevci from October 2008 until July 2010.
AB  - U ovom radu su prikazani dvogodišnji rezultati primene mašina i oruđa za nove tehnologije u biljnoj proizvodnji. Izvršena je uporedna analiza uticaja primene nove tehnologije i nove linije mašina, kao i uticaj konvencionalnog sistema obrade na nekoliko ratarskih kultura (suncokret, merkantilni kukuruz i pšenica). U toku ispitivanja, analizirani su uticaji primene nove linije mašina na: fizičke osobine zemljišta, morfološke osobine gajenih biljaka, utrošak energije i prinos, a takođe su analizirani i ekonomski aspekti primene. Na kontrolnim parcelama je istovremeno bio primenjen konvencionalni sistem obrade, radi uporedne analize prethodno pomenutih faktora. Ogledi su izvedeni na proizvodnim parcelama Instituta za kukuruz 'Zemun Polje' u Krnješevcima u periodu od oktobra 2008. godine do jula 2010. godine.

Trials were conducted on production plots of Maize Research Institute 'Zemun Polje' in Krnješevci from October 2008 until July 2010., U ovom radu su prikazani dvogodišnji rezultati primene mašina i oruđa za nove tehnologije u biljnoj proizvodnji. Izvršena je uporedna analiza uticaja primene nove tehnologije i nove linije mašina, kao i uticaj konvencionalnog sistema obrade na nekoliko ratarskih kultura (suncokret, merkantilni kukuruz i pšenica). U toku ispitivanja, analizirani su uticaji primene nove linije mašina na: fizičke osobine zemljišta, morfološke osobine gajenih biljaka, utrošak energije i prinos, a takođe su analizirani i ekonomski aspekti primene. Na kontrolnim parcelama je istovremeno bio primenjen konvencionalni sistem obrade, radi uporedne analize prethodno pomenutih faktora. Ogledi su izvedeni na proizvodnim parcelama Instituta za kukuruz 'Zemun Polje' u Krnješevcima u periodu od oktobra 2008. godine do jula 2010. godine.",

AB  - Mole drainage, on the right soil type and done properly can help reduce water logging problems. While surface drainage can improve the situation by removing excess surface water, in most cases the soil profile itself needs to be drained, so that crops can reach their potential, while damage by treading and compaction can be reduced. Mole drains do not drain ground water but remove water as it enters from the ground surface. Soils should have clay content in the range of 30 to 35 % to ensure long lasting mole channels. Heavy soils, with low rates of soil-water movement, require closely spaced (2-6 m apart) subsoil drain systems to provide sufficient water movement to control the effects of saltwater logging on an alfalfa field. Water management is critical for optimal production of alfalfa, with drought stress typically resulting in loss of production, and excess water leading to yield drops as well as stand losses.
AB  - Krtična drenaža, na odgovarajućem zemljištu i ispravno izvedena može da pomogne u smanjenju problema prevlaživanja. Iako površinska drenaža može da poboljša situaciju uklanjanjem suvišne površinske vode, u većini slučajeva zemljišni profil treba da bude dreniran, tako da usevi mogu da ostvare svoje potencijale i da se, smanje štete od gaženja i sabijanja. Krtični drenovi ne uklanjaju podzemnu vodu, ali uklanjaju vodu koja dolazi sa površine zemljišta. Zemljište bi trebalo da ima sadržaj od 30 do 35% gline da bi se osigurala dugotrajnost krtičnih kanala. Teška zemljišta, sa niskim stopama premeštanja zemljišne vode, zahtevaju manja rastojanja (2-6 m) sistema drenova za obezbeđivanje dovoljnog kretanja vode za kontrolu efekta zaslanjivanja - prevlaživanja na lucerištima. Uređenje voda je kritično za optimalnu proizvodnju lucerke, gde stres suše najčešće dovodi do gubitaka proizvodnje, kao što i višak vode dovodi do smanjenja prinosa, odnosno gubitaka.

AB  - The need of preservation and rational use of natural resources such is land requires the elimination of the usual practice of production and application of new technologies and new types of machines and tools. However, massive acceptation and successful application of new technologies and new types of machines and tools in practice requires certificates of manifestation the positive technical, technological and economic effects obtained through appropriate research. Bearing this in mind, the aim of this paper is to examine the economic effects of applying new technology and new types of machines and tools for the arrangement of soil's surface and depth in sunflower production. In this sense, conducted economic analysis shows that a change in technology and application of new types of machines and tools in sunflower production is economically justified, given that there is a reduction of variable costs per kilogram of produced sunflower by 4.77%. The research and results obtained in this analysis represent only the first phase of research of the economic effects of application of new types of machines and tools in crop production (in this case in sunflower production). The results indicate the need to expand research to other important crops.

Međutim, da bi nove tehnologije obrade i nove mašine i oruđa bili masovno prihvaćeni i uspešno primenjeni u praksi, potrebna je potvrda ispoljavanja pozitivnih tehničko-tehnoloških i ekonomskih efekata dobijena kroz odgovarajuća naučna istraživanja. Imajući to u vidu, cilj ovog rada je da se sagledaju ekonomski efekti primene nove tehnologije obrade i novih mašina i oruđa za uređenje zemljišta po površini i dubini u proizvodnji suncokreta. U tom smislu sprovedena ekonomska analiza pokazuje da je promena tehnologije obrade i primena novih mašina i oruđa u proizvodnji suncokreta ekonomski opravdana, s obzirom da dolazi do smanjenja varijabilnih troškova po kilogramu proizvedenog suncokreta za 4,77%.

AB  - In market conditions of business operations the main criterion of successful agricultural production is achieved economic results.

The need of preservation and rational use of natural resources, such as soil, requires the elimination of the usual practice of production and application of new technologies as well as new types of machines and tools.

Bearing this in mind, the aim of this paper is to examine the economic effects of prolonged effect of new technology and new types of machines and tools for the arrangement of soil's surface and depth in wheat production. In this sense, it is determined that a change in cultivation technology and application of new machines and tools in the first year of conducting the experiment has a positive prolonged effect in the second year of conducting the experiment as well, which is reflected in a reduction of variable costs per kilogram of produced wheat by 23.57%. The conducted research and results obtained in this analysis represent a continuation of research of economic effects of the application of new machines and tools for the arrangement of soil's surface and depth in individual crop production (a previous study included corn and sunflower).

AB  - The paper deals with subsequently effect of ameliorative tillage on the dynamics of some important productive morphology and productive characteristic in winter wheat. The trial was carried-out at the Maize Research Institute 'Zemun Polje' experimental fields in Krnjesevci near Belgrade on meadows chernozem soil type during 2009/10. The following ameliorative and conventional tillage systems were included in investigation: 1. Ameliorative tillage system includes new types machines for field systematization-scrapers (USM 5) in autumn, drainage plow on the depth 60-80cm, and sub-soiling with heavy vibratory sub-soiler VR 5 on 30-35cm depth. After basic tillage we prepared soil for seeding with preparation by disking and harrowing 2. Control variant without ameliorative measures. The following morphological and productive properties of winter wheat were studied: root biomass, stalk height, head, ear number, and grain yield. Ameliorative tillage systems had subsequently effects for all investigated morphology properties on this heavy soil type. Many of them are important for productive properties were statistically significant compared with control. Ameliorative tillage system increase significantly grain yield of winter wheat kg/ha compared with control.
AB  - Ispitivanje uticaja sistema meliorativne obrade zemljišta zasnovanog na novim konstrukcionim rešenjima i tehnologiji (ravnanje zemljišta+podrivanje krtičnim plugom+vibraciono razrivačko oruđe) tokom 2008/09, odnosno njegovog produžnog dejstva na morfološke i produktivne osobine ozime pšenice obavljeno je na imanju Instituta za kukuruz 'Zemun Polje' u Krnješevcima u 2009/10. godini. Pratili smo uticaj produžnog dejstva meliorativnog sistema obrade zemljišta na važnije morfološke osobine ozime pšenice u dva roka, u bokorenju i u klasanju.

abstract = "The paper deals with subsequently effect of ameliorative tillage on the dynamics of some important productive morphology and productive characteristic in winter wheat. The trial was carried-out at the Maize Research Institute 'Zemun Polje' experimental fields in Krnjesevci near Belgrade on meadows chernozem soil type during 2009/10. The following ameliorative and conventional tillage systems were included in investigation: 1. Ameliorative tillage system includes new types machines for field systematization-scrapers (USM 5) in autumn, drainage plow on the depth 60-80cm, and sub-soiling with heavy vibratory sub-soiler VR 5 on 30-35cm depth. After basic tillage we prepared soil for seeding with preparation by disking and harrowing 2. Control variant without ameliorative measures. The following morphological and productive properties of winter wheat were studied: root biomass, stalk height, head, ear number, and grain yield. Ameliorative tillage systems had subsequently effects for all investigated morphology properties on this heavy soil type. Many of them are important for productive properties were statistically significant compared with control. Ameliorative tillage system increase significantly grain yield of winter wheat kg/ha compared with control., Ispitivanje uticaja sistema meliorativne obrade zemljišta zasnovanog na novim konstrukcionim rešenjima i tehnologiji (ravnanje zemljišta+podrivanje krtičnim plugom+vibraciono razrivačko oruđe) tokom 2008/09, odnosno njegovog produžnog dejstva na morfološke i produktivne osobine ozime pšenice obavljeno je na imanju Instituta za kukuruz 'Zemun Polje' u Krnješevcima u 2009/10. godini. Pratili smo uticaj produžnog dejstva meliorativnog sistema obrade zemljišta na važnije morfološke osobine ozime pšenice u dva roka, u bokorenju i u klasanju. Na kraju vegetacionog perioda pred žetvu uzeli smo uzorke za prinos zrna i druge morfološke karakteristike. Nasuprot meliorisanoj površini imali smo kontrolnu površinu.

AB  - In this paper influence of two heavy mechanical type tillage systems: A - conventional tillage system and B - conservation tillage system is analyzed, and two different treatments of herbicides on yield of maize as well. The experiments are carried on production fields of 'Institutes for maize - Zemun Polje', during 2008/09 years. The focus of this research, among other effects, is on maize yield, as relevant parameter of efficiency of plant production. Right choice of soil tillage system and treatments of herbicides are key point for improvement of plant production, especially for grain yield aspects. Soil tillage system B in comparation with soil tillage system A is 10% more efficient. Treatment with herbicides 1 in comparation with treatment with herbicides 2 is 9,42% more efficient. Combining these two variable parameters (soil tillage systems and treatment of herbicides), the most efficient is model B+1, with grain yield increased up to 18,7%.
AB  - U radu je analiziran uticaj dva sistema obrade zemljišta teškog mehaničkog sastava: A - konvencionalnog i B - konzervacijskog, kao i primene dva različita tretmana herbicida na prinos merkantilnog kukuruza. Ogledi su izvedeni na proizvodnim površinama Instituta za kukuruz iz Zemun Polja, tokom 2008/09 godine. Akcenat istraživanja je, pored ostalih pratećih efekata, usmeren na prinos kukuruza kao relevantnog pokazatelja efikasnosti biljne proizvodnje. Pravilan izbor sistema obrade zemljišta i tretmana herbicidima svakako može unaprediti proizvodnju, naročito sa aspekta ostvarenog prinosa gajene kulture. Povećanje prinosa uslovljen modelom obrade je u korist modela B, veći za 10%. Povećanje prinosa uslovljen tretmanom herbicida je u korist tretmana 1, veći za 9,42%. Sa dejstvom ove dve agrotehničke mere, kao najoptimalnija kombinacija pokazao se model B+1, sa združenim efektom povećanja prinosa do 18,7% u odnosu na druge modele.

AB  - Agricultural enterprises are facing today with numerous problems when they make differential calculations as well as in their practical application. The enterprises have to apply various agro-technical, organization, economic, technical and technological measures aiming at the change of volume, structure or way of production. Those changes, especially ones concerning size, structure or way of production are influencing both revenues and costs. This is particularly expressed in actual economic crisis, because the crisis increases financial risk of financial resources utilization. The basic research goal of this paper is to indicate onto importance of differential calculation, on possibilities and limitations of its application as well as on way of its construction. On the created model of agricultural enterprise dealing with the crop production, taking intro account different assumptions and by application appropriate methods, there have been analyzed the obtained results. This research has showed economic justification of planned and realized changes in the structure of crop production.
AB  - Poljoprivredna preduzeća se danas suočavaju sa velikim brojem problema prilikom sastavljanja diferencijalne kalkulacije i načina njene primene u praksi. Preduzeća moraju primeniti različite agrotehničke, organizaciono-ekonomske i tehničko-tehnološke mere, koje će ih dovesti do promene obima, strukture ili načina proizvodnje. Promene u obimu, strukturi ili načinu proizvodnje se odražavaju na prihode s jedne i na troškove s druge strane. Ovo je naročito izraženo zbog postojeće svetske ekonomske krize, jer sama kriza kao takva povećava finansijski rizik prilikom ulaganja novčanih sredstava.

AB  - Problems that occur when processing the soil with heavy mechanical type of composition can not be solved without changing the existing cultivation system. Soils with heavy mechanical type of composition demand a cultivation system that ensures preservation of natural potential and fertility resources. Bearing this in mind, the objective of this research is to examine the economic consequences of applying new types of machines and tools for the arrangement of soil's surface and depth, then to detect the most important factors influencing this and finally to contribute successfully to the formulation of the answers on questions is their use profitable and under what conditions. The results of this study suggest that is possible to expect the positive effects of applying new technologies and new machines and tools for the arrangement of soil's surface and depth.
AB  - Problemi koji se javljaju pri obradi zemljišta sa teškim mehaničkim sastavom ne mogu se rešiti bez promene postojeće tehnologije obrade zemljišta.

Na osnovu dosadašnjih rezultata istraživanja moguće je očekivati pozitivne efekte primene analiziranih mašina i oruđa što je od presudne važnosti prilikom donošenja odluke o opravdanosti njihovog uvođenja.

AB  - In this paper influence of two tillage systems (conventional and conservation) on sunflower and maize yield is analyzed. The experiments are carried on production fields of Maize Research Institute 'Zemun Polje'. The conventional tillage system gave satisfying yields of both plants. This type of tillage is acceptable in years with medium rainfall during the vegetation period. When amount of precipitation was not evenly distributed during the year, yield was significantly lower, or even omitted if the differences in amount of precipitation were extreme. With conservation tillage system, the yield was higher, in comparison with conventional system, even in the years with medium amount of precipitation during the vegetation period. Sunflower and maize yields were 8.6% and 9.9% higher with conservation tillage system than with conventional system. The research is necessary to continue in order to see the effects of conservation tillage on other breeding plants, and also for observing the effects of continuous usage of this tillage system (in second, third and fourth year of production).

AB  - The paper deals with the effects of ameliorative tillage on the dynamics of some important physical soil properties in maize. The trial was carried-out at the experimental fields Krnjesevci of Maize Research Institute 'Zemun Polje' on meadows chernozem soil type. The following ameliorative and conventional tillage systems were included in investigations: 1. Ameliorativel tillage system - (ATS) - includes new types machines for field systematization-scrapers (USM 5) in autamn, drainage plow on the depth 60-80 cm, and subsoiling with heavy vibratory subsoiler VR 5. on 30-35 cm depth. After basic tillage we prepared soil for seeding with preparation by disking and harrowing 2. Conventional tillage - (CT) - in this case includes ploughing to the depth of 30-35cm + presowing preparation by disking and harrowing was control. The following soil properties were studied: bulk density, total porosity, moisture weight and volume percent, and total water content in different layers in m3, in two period of time after first and after second interrow cultivation in maize on the different depth 0-10; 10-10; 20-30. Ameliorative tillage systems have better effect for all investigated soil properties on this heavy soil type compared with control with classical tillage system.
AB  - Ispitivanje uticaja jednog novog sistema meliorativne obrade zemljišta na promene nekih važnijih fizičkih osobina zemljišta u usevu kukuruza obavljeno je na imanju Instituta za kukuruz 'Zemun Polje' u Krnješevcima. U ispitivanju smo imali dve varijante: Var. 1. - Sistem meliorativne obrade zemljišta (ravnanje + rad krtičnog pluga + podrivanje + predsetvena obrada zemljišta); Var. 2. - Kontrola. Konvencionalna obrada zemljišta (oranje raonični plugom + predsetvena obrada zemljišta). Pratili smo dinamiku važnijih fizičkih osobina zemljišta u usevu kukuruza u dva roka posle posle prvog i neposredno posle drugog međurednog kultiviranja. Uzorci su uzimani sa cilindrima po Kopeckom, a dalje obrađeni u laboratoriji. Ispitivani su uticaji meliorativne obrade zemljišta na zapreminsku masu, vlažnost zemljišta, poroznost i količinu vode po hektaru na tri dubine ispitivanja: od 0-10 cm; 10-20 cm; 20-30 cm.

Ameliorativel tillage system - (ATS) - includes new types machines for field systematization-scrapers (USM 5) in autamn, drainage plow on the depth 60-80 cm, and subsoiling with heavy vibratory subsoiler VR 5. on 30-35 cm depth. After basic tillage we prepared soil for seeding with preparation by disking and harrowing 2. Conventional tillage - (CT) - in this case includes ploughing to the depth of 30-35cm + presowing preparation by disking and harrowing was control. The following soil properties were studied: bulk density, total porosity, moisture weight and volume percent, and total water content in different layers in m3, in two period of time after first and after second interrow cultivation in maize on the different depth 0-10; 10-10; 20-30. Ameliorative tillage systems have better effect for all investigated soil properties on this heavy soil type compared with control with classical tillage system., Ispitivanje uticaja jednog novog sistema meliorativne obrade zemljišta na promene nekih važnijih fizičkih osobina zemljišta u usevu kukuruza obavljeno je na imanju Instituta za kukuruz 'Zemun Polje' u Krnješevcima. U ispitivanju smo imali dve varijante: Var. 1. - Sistem meliorativne obrade zemljišta (ravnanje + rad krtičnog pluga + podrivanje + predsetvena obrada zemljišta); Var. 2. - Kontrola. Konvencionalna obrada zemljišta (oranje raonični plugom + predsetvena obrada zemljišta). Pratili smo dinamiku važnijih fizičkih osobina zemljišta u usevu kukuruza u dva roka posle posle prvog i neposredno posle drugog međurednog kultiviranja. Uzorci su uzimani sa cilindrima po Kopeckom, a dalje obrađeni u laboratoriji. Ispitivani su uticaji meliorativne obrade zemljišta na zapreminsku masu, vlažnost zemljišta, poroznost i količinu vode po hektaru na tri dubine ispitivanja: od 0-10 cm; 10-20 cm; 20-30 cm.

Dilema da li prevrtati masu zemljišta ili je dubinski rastresati zavisi od konkretnih osobina zemljišnog tipa.

AB  - Serbian agricultural producers are facing currently with a large number of challenges that significantly influence their business activities. One of them is for sure a high fuel price. The recent fuel price increase has caused a lot of concern among agricultural producers regarding its impact on operating costs and farm profitability. However, those higher costs will probably reflect themselves onto direct reduction in profit in the short run because the producers' possibilities are limited as to the changes they can economically make. While no one knows with certainty what will happen in the future, the current developments on the world market as well as the analysts' estimates indicate that we are likely to see continued high diesel fuel prices. Bearing this in mind, the objective of this research is to emphasize an importance of the fuel price change for optimization of total operating costs of the tillage agricultural machinery, then to detect the most important factors influencing this change and finally to contribute successfully to the formulation of the answers on mentioned questions. The results of this study suggest that for an increase of the agricultural machinery utilization efficiency as well as for minimization of their operating costs, it is necessary to start making more adequate management decisions. This is certainly one of the safe ways for alleviation of the consequences caused by the high fuel price mostly influenced by the world fuel market trends.
AB  - Poljoprivredni proizvođači u Srbiji suočavaju se sa velikim brojem izazova koji značajno utiču na njihovo poslovanje. Jedan od njih je svakako visoka cena goriva. Skorašnje povećanje cene goriva nateralo je mnoge od njih da se zapitaju kakav će to uticaj imati na troškove proizvodnje tj. kako će se odraziti na profitabilnost poslovanja gazdinstva. Ono što je izvesno je da će u kratkom roku, ovako visoka cena dovesti do smanjenja profita, zato što su mogućnosti vlasnika da u kratkom roku učine ekonomska prilagođavanja prilično limitirane. I dok niko sa sigurnošću ne može da pretpostavi šta će se dešavati u budućnosti, trenutna kretanja na svetskom tržištu i procene analitičara govore da i dalje treba očekivati održavanje cene na visokom nivou. Imajući to u vidu, cilj ovog istraživanja je da se ukaže na značaj promene cene goriva za optimizaciju ukupnih troškova upotrebe poljoprivredne mehanizacije za obradu zemljišta, da se otkriju najvažniji faktori koji na to utiču i da se sagleda njihov uticaj, uz nastojanje da se na taj način doprinese uspešnijem formulisanju odgovora na napred postavljena pitanja. Na osnovu dosadašnjih rezultata istraživanja može se konstatovati da je za povećanje efikasnosti korišćenja poljoprivredne mehanizacije i minimiziranje troškova njihove upotrebe, od presudnog značaja celishodno i blagovremeno sprovođenje adekvatnih mera iz oblasti menadžmenta. To je svakako jedan od sigurnih načina za ublažavanje posledica izazvanih visokom cenom goriva na čije formiranje prevashodni uticaj imaju kretanja na svetskom tržištu derivata.

AB  - Soils with heavy mechanical type of composition demand a cultivation system that ensures preservation of natural potential and fertility resources. This system must also prevent degrading processes and ensure an optimal water motion within the soil, with an optimal usage of energy and labor. In Serbia there are over 0.4 million hectares of soil with heavy mechanical type of composition, and over 0.1 million hectares of diversely damaged soil. Every year, during different degrading actions, another 1000 hectares of soil are damaged. Agricultural machinery for tillage of the soils with heavy mechanical composition and damaged soils should fulfill the basic demands: arrangement of the soil's surface and depth, preservation of the soil's biological system, regulation of the water and air system, thus enabling an efficient irrigation, conservation of the natural humidity, insurance of an efficient irrigation, perseverance of the natural moisture, insurance of a rational consumption of energy, labor and resources for the defined structure and level of agricultural production. Researches that are conducted by the Institute of Agricultural Engineering, Faculty of Agriculture, Belgrade, Serbia, and the Institute of Corn, Zemun Polje, Serbia, are set to determine the technical, technological and economic aspects of the appliance of new types of machines and tools for the arrangement of soil's depth and surface. These new types of machines include: universal soil arrangement machine USM-5, drainage plough DP-4 and vibratory subsoiler VR-5, applied on the degraded chernosem soil type and on the marsh soil type (parcel Tab. XVII, heavy mechanical type of composition, damaged and unfavorable water and air conditions), on the location of an experimental property of the Institute of Corn in Krnješevci, Serbia. Basic characteristics of the soil are determined, control parcels are defined and marked, new technology and machines for soil's surface and depth arrangement are applied. Specific technical and technological parameters were measured during the work of new machine types.

AB  - Measurements and control of angular velocity are encountered in many fields of industry, including in agricultural machines. Devices used for measurements of angular velocity are of mechanical or electrical type. The usage of electrical devices which are based on the application of appropriate sensors of angular velocity becomes greater lately. In this paper are given the characteristics of angular velocity sensors which are applied in agricultural machines (optoelectronic, capacitance and electromagnetic sensors and those sensors which are based on Hall's effect) and their specific qualities are pointed out.

AB  - Because the humidity of soil is one of the essential factors that determine the optimal plant growth and crop production, this paper discusses in detail various techniques, methods and modes of the measurement of soil humidity. Devices, sensors and additional equipment for the measurement of humidity are analyzed depending on the different types of the agricultural crops and characteristics of the soil. In this paper is given a review and a comparative analysis of sensors as the parts of the various products which measure a soil humidity (analog and digital). The selection of the most suitable location for sensors, their installation, placement and necessary depth is also presented. In this paper are analyzed the characteristics of sensors (performances, cost-effectiveness in the agricultural production), their maintenance and the timely detection of failures while in operation.
