AB  - Performing works with the land where a lot of mechanical work is engaged, such as making pits for planting fruit, needs to be mechanized. This replaces human labour with a tractor machine aggregate with an increase in productivity and thus makes the process cheaper. For the proper selection of individual means of mechanization, it is important to determine the optimal 
agrotechnical parameters of their application. Proper selection and use of mechanization tools for planting have a decisive influence on the intensity and progress in cultivation technology. Defining 
energy and exploitation parameters of tractor-machine aggregates during mechanized construction of pits is the subject of this research. The pits are intended for individual planting of 
fruit seedlings as well as the installation of trellis poles. The test results of the tractor-machine aggregate show that the lowest driving force engaged for drilling was achieved in the field and 
was 6.36 kW for the excavated pit with the depth of 885 mm and with a diameter of 520 mm, the number of revolutions of the drill was 93 rpm and drilling was achieved in 27 s. The highest 
driving force for drilling was engaged in field III, which was 30.8 kW for the excavated pit 780 mm deep with a diameter of 490 mm, the number of revolutions of the drill bit was 111 rpm and 
drilling was realized in 30 s. The results obtained in these tests show that the consumption of motor power largely depends on the type of soil, the quality of previous soil preparations and the number of revolutions of the tractor PTO shaft. The time required to move the aggregate from one to the next drilling site is crucially influenced by the terrain configuration, the state of soil preparation and the skill of the tractor driver and auxiliary worker.

AB  - The application of precision agriculture in chemical plant protection enables the 
realization of high yields while preserving natural resources. The quality of chemical applications 
depends on the type of technical system that performs for this job. The task of the technical system 
is to protect the cultivated crop precisely, economically and while preserving the environment, and 
all that depends on the precission and the quality of application of the protective liquid. The use of 
UAV´s in chemical plant protection enables precise application of protective liquid, so their 
application is increasing in the protection of numerous crops. The same trend has been observed 
in field production, where the use of UAV´s is on the rise. The paper compares the exploatational 
and technological characteristics of the field sprayer (FS) and unmanned aerial vehicle (UAV) in 
the chemical protection of wheat. The amount of deposited protective liquid on plants and losses of 
deposited on the surface of the earth were monitored. Using UAV (T4: V = 3 m·s-1
, H = 1 m), the 
amount of protective liquid on the plant was determined to be 0.185 mg·l-1
compared to 0.037 mg·l 1
at FS, while the losses were 0.01 mg·l-1
at FS and 0.085 mg·l-1
at UAV. The presence of Fusarium 
(Fusarium spp.) after chemical protection was analyzed according to the compared technical 
systems and set treatments. It was recorded for 20% higher efficiency in protection against 
Fusarium (Fusarium spp.) using UAV (T5: V = 3 m·s-1
, H = 2 m) compared to FS. The values of 
wheat yield were measured according to the compared technical systems and set treatments, where 
the highest wheat yield was achieved using UAV (T5) with 10,667.7 kg·ha-1
, while using FS, 
14.84% lower yield was achieved. The application of UAV´s in the segment of chemical plant 
protection enables us to effectively protect crops, economical and optimized production, while 
preserving the environment in a way that has been completely new and unknown until now.

AB  - Bee pollen is very important in the nutrition of bees since it provides them with 
proteins, lipids, vitamins and minerals. Bee pollen also has a significant nutritive value as a 
supplement to human nutrition. Fresh bee pollen contains a large quantity of moisture 
which favors development of various microorganisms. In order to preserve pollen from 
spoilage its dehydration in controlled conditions is commonly performed. In this paper, 
freeze-drying was proposed as a conservation method. Results showed increment in the 
drying rate and improve the product quality compared to traditional hot air drying. The 
current work provides theoretical and technical reference for applying this type of 
technology.

AB  - The technical accuracy of the machine is a prerequisite for the effective 
implementation of chemical protection in fruit and grapevine production. The paper 
presents the results obtained during the control testing of 50 different models of 
orchard sprayers, with different period of exploitation in growers throughout Serbia 
that are used in intensive fruit and grapevine production. During the control testing, a 
large number of parameters were monitored, using standardized methods and test 
procedures. Comparison of the obtained data was applied to four groups of orchard 
sprayers (defined by the period of the exploitation). The technical accuracy of the 
individual orchard sprayer is expressed by the coefficient of the technical correctness 
(Cta) according to individual marks of the tested parameters of orchard sprayers. 
Out of the total number of investigated orchard sprayers, 12% of the orchard sprayers 
are in exploitation for less than three years, while the largest number of orchard 
sprayers, and 42% is in exploitation for seven years or more. The technical accuracy of 
Group 1 orchard sprayers was sufficiently high, except for the parameters related to 
the Measuring regulatory system (Cta = 0.80) and the Nozzles (Cta = 0.86). In Group 2, 
a decrease in the coefficient of technical accuracy in all parameters was observed with 
respect to the sprayers from Group 1, which was particularly pronounced for Agitators 
(Cta = 0.50) and Nozzles (Cta = 0.68). The orchard sprayers from Group 3 are 
characterized by a low coefficient of technical accuracy for the Nozzles (Cta = 0.37), 
while Group 4 orchard sprayers have a very low coefficient of technical accuracy in all 
tested parameters. The level of technical accuracy of the orchard sprayers used in 
intensive fruit and grapevine production is directly dependent on the period of their 
exploitation.

abstract = "The technical accuracy of the machine is a prerequisite for the effective 
implementation of chemical protection in fruit and grapevine production. The paper 
presents the results obtained during the control testing of 50 different models of 
orchard sprayers, with different period of exploitation in growers throughout Serbia 
that are used in intensive fruit and grapevine production. During the control testing, a 
large number of parameters were monitored, using standardized methods and test 
procedures. Comparison of the obtained data was applied to four groups of orchard 
sprayers (defined by the period of the exploitation). The technical accuracy of the 
individual orchard sprayer is expressed by the coefficient of the technical correctness 
(Cta) according to individual marks of the tested parameters of orchard sprayers. 
Out of the total number of investigated orchard sprayers, 12% of the orchard sprayers 
are in exploitation for less than three years, while the largest number of orchard 
sprayers, and 42% is in exploitation for seven years or more. The technical accuracy of 
Group 1 orchard sprayers was sufficiently high, except for the parameters related to 
the Measuring regulatory system (Cta = 0.80) and the Nozzles (Cta = 0.86). In Group 2, 
a decrease in the coefficient of technical accuracy in all parameters was observed with 
respect to the sprayers from Group 1, which was particularly pronounced for Agitators 
(Cta = 0.50) and Nozzles (Cta = 0.68). The orchard sprayers from Group 3 are 
characterized by a low coefficient of technical accuracy for the Nozzles (Cta = 0.37), 
while Group 4 orchard sprayers have a very low coefficient of technical accuracy in all 
tested parameters. The level of technical accuracy of the orchard sprayers used in 
intensive fruit and grapevine production is directly dependent on the period of their 
exploitation.",

AB  - The successful implementation of chemical protection depends on two main factors. 
The first factor relates to the selection of the compound and its application in adequate time, while 
the second factor relates to the technical functionality of the parts of the machines used for the 
application of the protective liquid, i.e. the nozzle. The technical functionality of the sprayer 
elements, the proper tuning (calibration) and the correct selection of the nozzle all have a great 
influence on the proper functionality of the sprayer elements. The proper technical functionality of 
the sprayer is a prerequisite for the effective application of the protective liquid, for the financial 
savings and the environmental protection as well as. In our practice, a particular problem is the fact 
that agricultural producers do not perform regular annual controls on both the nozzles themselves 
and the other elements of the sprayers.
This paper presents a comparative analysis of several types of sprayers, which have the same 
type of nozzles, but with different factory declared flow. 25 sprayers were tested and divided into 
four groups according to the exploitation period. In the first group of sprayers the nozzles were 
within the factory declared flow rate (100% correct), while the fourth group of sprayers had half of 
the nozzles (50% defective) for replacement. This research shows that the length of the exploitation significantly influences on the technical functionality of the sprayers. In order for as many sprayers as possible to meet the technical standards of EN 13790 to be applied in practice, it is necessary to regularly check the technical functionality of the nozzles, and all other elements of the sprayers by the users themselves, and periodically also by the authorized laboratories.

AB  - The paper analyzes the possibility and necessity of applying special types of robots 
(mini unmanned aircraft with different constructions with the UAV tag) in agriculture 
(agrodrone). Year 2015 was declared (Fortune Magazine, 2016) as the year of increase 
and widespread application of drone aircraft in all areas of human activity, particularly 
in agriculture and forestry (75% usage). This is important for large areas of farms, whe re the mini aircraft have numerous useful functions and a very cost-effective application.
Agro drone flight (flight time of 45 min, and the flight altitude of 1 m to 120 m) 
can be used to analyze more functional parameters on about 120 ha of crops, and all 
data can be sent to multiple locations (Audit Information Centre, mobile phones users 
and the like). Today some types of agro drones have a relative price of 2000 USD, if 
the users (farmers) assemble the drone themselves after purchasing it in parts. However 
the price of these mini aircraft can be up to 250,000 US$ for specific models used by 
the military, when equipped with special infrared cameras, sensors and HD video tech nology, which is controlled by an operator (pilot) from the surface. Usage of agro 
drones may be expensive at first, but research shows that many data collected (for 
example, identifying the species of insects and plant diseases, irrigation, yield asse ssment or monitoring the movement of animals on farms), help farmers to regain inve sted funds, sometimes for only one year. Farmers can use these aircraft in order to 
establish a rational and precise use of pesticides, herbicides, mineral fertilizers, all 
based on data obtained from the agro drone, used for precision agriculture systems. In 
this sense, the farmers have significant financial benefits, since one drone flight has an 
operational cost of a water bottle, and the data collected has great value. There are 
anecdotes about farmers in the US who first buy an agro drone and afterwards a hunting 
dog. The paper presents some structures of agro drones as well as ideas for their possi ble future application in agriculture of the R. of Serbia.

AB  - Natural liquid manure as a suspension of overall cow and related categories excreta, 
with out of admixtures of bedding matherials and residues of anused feed, is diversified 
energetic source, because it can produce gas, heat, electric power, fuel, etc. Teh introduc tion of natural liquid manure in treatment towards energy production, contribute not only 
to energy efficency of farm, but also to better envirnoment protection because of increased 
emission of sulfur dioxide, carbon dioxide and nitrogen dioxide, compared to combusti on of fossil fuels. In addition, a significant ammount of pathogens are destroyed and 
weeds seeds that can be found in manure germination energy is significantly lower.
This paper presents optimal technology and technical solutions of liquid manure 
usage for improving energy efficiency of small farms, and also the folloving total usa ge of liquid manure as organic fertilizer. In this paper, a mini farm of 50 dairy cows, 
which are now common i Serbia has been considered. Methods of collecting, proce ssing, preparation, and use of liquid manure, in our conditions are not met at a wider 
application, due to the extensive production. 
Huge ammounts of this organic fertilizer with graet nutritive potential in forms that 
are easily accessible to plants are not used in any way, and are uncontrollably released 
to envirnoment cousing pollution to envirnoment in any possible way. That practise 
must be stopped.
Economic effects in countries with less developed livestock production, such as 
ours, suggest that this issue must be given adequate attention and redirected the way of 
production, which, with secondary products can significantly improve the outcome. 
This paper gives direction to it.

AB  - This paper is the result of studying effects of mechanical 
chamomile harvesting on yield and quality of harvested chamomile. Chamomile 
(Chamomilla recutita (L) Rausch.) was harvested at three time intervals (T1 – 240 
days, T2 – 250 days and T3 – 260 days after sowing) by three conceptually 
different harvesters. The results achieved indicate that the harvester type 
significantly influences quality of harvested chamomile, whereas it is not 
influenced by chamomile harvesting time. Quality of harvested chamomile was 
classified into four categories, and it was observed that the greater number of 
rotations of a picking device increased the content of the first category of quality. 
The harvester A achieved 54.79% of the first category of quality in respect to the 
harvester B achieving 50.26% and the harvester C with 42.93%.

AB  - U radu su predstavljeni rezultati istraživanja nesrećnih slučajeva sa traktorima i drugim 
mobilnim poljoprivrednim mašinama u uslovima poljoprivredne proizvodnje (van javnih 
saobraćajnih površina), sa posebnim osvrtom na nesreće sa koje su za ishod imale tragično 
nastradale osobe. Istraživanja su sprovedena u periodu od 2005-2010. godine, u Republici 
Srbiji bez autonomnih pokrajina (AP Vojvodine i AP Kosova i Metohije). Podaci o nesrećnim 
slučajevima su prikupljeni za 18 administrativnih oblasti, uključujući i Beogradsku oblast, dok 
su ostalih 17 administrativnih oblasti obuhvatile ostatak Republike Srbije (Beogradski region, 
region Šumadije i Zapadne Srbije i region Južne i Istočne Srbije). U periodu istraživanja, izvan 
javnog saobraćaja Republike Srbije, desilo se ukupno 1056 registrovanih nesreća u kojima su 
učestvovali traktori i druge mobilne poljoprivredne mašine ili 176 nesreća prosečno godišnje u 
periodu istraživanja. U 183 nesreći ili u 17,33% od ukupnog broja nesreća, bilo je poginulih tragično nastradalih lica, dok je u 873 nesreće ili u 82,67% slučajeva nesreća bilo povređenih 
lica. Analizirajući broj lica koja su nastradala u pomenutim nesrećama, možemo konstatovati 
da je u 1056 nesreća koje su se dogodile u periodu istraživanja, nastradalo ukupno 1242 osobe 
ili 207 osoba prosečno godišnje u periodu istraživanja. Od ovog broja, 186 osoba ili 14,98% 
su tragično nastradale (poginule), dok je 1056 lica ili 85,02% bilo teže i lakše povređeno. 
Analiziranjem prethodno pomenutih podataka vezanih za nesreće sa traktorima i drugim 
mobilnim poljoprivrednim mašinama van javnog saobraćaja, možemo zapaziti da učešće 
nesreća sa poginulim-tragično nastradalim licima u ukupnom broju nesreća veoma veliko 
(17,33%), kao i učešće tragično nastradalih u ukupnom broju nastradalih lica (14,98%).

abstract = "U radu su predstavljeni rezultati istraživanja nesrećnih slučajeva sa traktorima i drugim 
mobilnim poljoprivrednim mašinama u uslovima poljoprivredne proizvodnje (van javnih 
saobraćajnih površina), sa posebnim osvrtom na nesreće sa koje su za ishod imale tragično 
nastradale osobe. Istraživanja su sprovedena u periodu od 2005-2010. godine, u Republici 
Srbiji bez autonomnih pokrajina (AP Vojvodine i AP Kosova i Metohije). Podaci o nesrećnim 
slučajevima su prikupljeni za 18 administrativnih oblasti, uključujući i Beogradsku oblast, dok 
su ostalih 17 administrativnih oblasti obuhvatile ostatak Republike Srbije (Beogradski region, 
region Šumadije i Zapadne Srbije i region Južne i Istočne Srbije). U periodu istraživanja, izvan 
javnog saobraćaja Republike Srbije, desilo se ukupno 1056 registrovanih nesreća u kojima su 
učestvovali traktori i druge mobilne poljoprivredne mašine ili 176 nesreća prosečno godišnje u 
periodu istraživanja. U 183 nesreći ili u 17,33% od ukupnog broja nesreća, bilo je poginulih tragično nastradalih lica, dok je u 873 nesreće ili u 82,67% slučajeva nesreća bilo povređenih 
lica. Analizirajući broj lica koja su nastradala u pomenutim nesrećama, možemo konstatovati 
da je u 1056 nesreća koje su se dogodile u periodu istraživanja, nastradalo ukupno 1242 osobe 
ili 207 osoba prosečno godišnje u periodu istraživanja. Od ovog broja, 186 osoba ili 14,98% 
su tragično nastradale (poginule), dok je 1056 lica ili 85,02% bilo teže i lakše povređeno. 
Analiziranjem prethodno pomenutih podataka vezanih za nesreće sa traktorima i drugim 
mobilnim poljoprivrednim mašinama van javnog saobraćaja, možemo zapaziti da učešće 
nesreća sa poginulim-tragično nastradalim licima u ukupnom broju nesreća veoma veliko 
(17,33%), kao i učešće tragično nastradalih u ukupnom broju nastradalih lica (14,98%). 
U istom periodu, kada su u pitanju saobraćajne nesreće na javnim putevima Republike Srbije, 
učešće tragično nastradalih u ukupnom broju nastradalih lica iznosilo 4,2%, pa možemo tvrditi da su nesreće sa traktorima i drugim mobilnim mašinama u poljoprivredi (van javnog

AB  - Contemporary, farm oriented, milk production involves obtaining of highly valuable, hygienically safe 
product. At the same time, farmers are under constant pressure to find new ways to reduce production 
costs. One of the most important factor in the total structure of costs are costs of energy. This paper 
presents the analysis of possibilities and effectiveness of usage of the system for recovering heat 
obtained by milk cooling process. The system consists of a heat pump " milk - water ", plate type pre -
cooler with counter flow of water and milk and storage vessel. The heat obtained from milk cooling 
process, is used to heat water instead of being wasted to the environment. Warm water is required on 
the farm for many reasons. Significant energy savings can be made by using this system. Experimental 
investigation was carried out on the family farm, where the milking was performed twice a day. After 
each milking, milking equipment is washed with warm water. The results showed that the application 
of this system can realize significant cost savings, as well as the potential of improving the efficiency 
of individual components of the system.

AB  - Analysis of agricultural production potential Serbia indicates that farms have a 
number of disadvantages from the point of application demands of modern agricultural 
production, primarily the application of modern machinery. The small size of the esta te and the relatively high fragmentation possession speak clearly about the impossibility 
of rational use of modern technology, high-performance and high-quality performance 
of business processes. Unfavorable age structure, a relatively small number of agricul tural households, as well as a small number of young people who see their future in a 
rural farm, affecting in particular the formation of farmer awareness (without ambition, 
lack of will, a chronic lack of funds).
Even before the 3-4 decades with the same or similar problems were faced and 
developed countries of Europe. Today this problem, in these countries, beyond the 
associations known as “machinery rings”. The characteristic that most affects the occu rrence of forming machinery rings share of machinery in production costs. In order for 
a machine-ring “lived” and evolved, it’s a big commitment machine during the year, 
but should not be neglected, and the impact of humans.
The first forms of association in the form of machinery rings in Serbia were orga nized in the municipalities of Tutin, Sjenica and Prijepolje within the international 
project, as well as in Becej, Opovo and back through the village of Peter spontaneous 
initiative and interest of farmers. The future of machinery rings in Serbia lies in the 
formation of informal groups of farmers, which would support the future of agricultu ral policy to this form of association and the business moved to the status of a legal 
entity. Then the machine rings, formed as a legal person, get the necessary business 
climate for successful and efficient business.

AB  - The paper presents comparison of two soil tillage systems in maize, winter wheat and sunflower growing in Srem region, Serbia, during 2008-2011. Tillage systems and implements were: conventional system (CT) - plough, disc-harrow and combined implement, and conservation system (ST) – vibratory subsoiler, disc-harrow and combined implement. The aim of testing was comparison of different tillage systems energy consumption and its influence on yield and profit. Results indicate that conventional tillage (CT) system was the lower energy consumer with 433.18 MJha-1, or conservation (ST) system spent 10.08% energy more. In the first season the greatest yield of maize, 7,083 kgha-1, achieved conservation tillage (ST) system while conventional tillage (CT) system achieved 9.92% lower yield. Second season the greatest yield of winter wheat, 4,525 kgha-1, achieved with conservation tillage (ST) system with regard to conventional (CT) system with 3,577 kgha-1. Third season the greatest yield of sunflower 3,011 kgha-1, achieved conservation tillage (ST) system again, with regard to conventional (CT) system with 8.56% lower yield.

AB  - U ovom radu je analizirana i ispitana energetska efikasnost sušenja semenskog kukuruza u doradnom centru Instituta za kukuruz 'Zemun Polje' u Zemunu. Podaci o radu starog sistema sušenja koji je kao energent koristio prirodni gas, analizirani su i upoređeni sa energetskim parametrima novog sistema, koji kao energent koristi usitnjeni oklasak dobijen u procesu krunjenja semenskog kukuruza. Rad se takođe bavi i razmatranjem ekoloških aspekata korišćenja oklaska kao goriva i tehno-ekonomskom opravdanošću primene ovakvog sistema sušenja. .
