Use of plants for energy production / Upotreba biljaka za proizvodnju energije
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2006)
We can, beside food / fodder, produce different plants to obtain various forms of energy (electricity, heat, fuel) on the fields. All together with wood from forests and other sources, biomass is the biggest guarantee for ...
Energy aspects of sprincler irrigation / Energetski aspekti navodnjavanja kišenjem
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2008)
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 ...

(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2012)
The aim of this study was to use results of experimental work to analyse effects of maize irrigation and to quantify basic parameters that are included into exploitation costs of a long-ranged self-propelled sprayer, so ...
Direct energy input structure in mercantile corn production / Struktura direktnih energetskih inputa u proizvodnji merkantilnog kukuruza
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2008)
In this paper structure direct energy input in mercantile corn production is presented with special review on: energy consumption for tillage and seeding in different tillage technology as well as energy consumption for ...
Influence of greenhouse covering material on energy consumption / Uticaj pokrivnog materijala na potrošnju energije u objektima zaštićenog prostora tunel tipa
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2007)
Greenhouse production in Serbia region is, in most cases, carried out in tunnel structures covered with single or double PE folia. Reason for this is greenhouse coverings and structures market which is pretty much uniform ...
Energy efficiency of the lettuce greenhouse production / Energetski bilans proizvodnje salate u objektima zaštićenog prostora različite konstrukcije
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2010)
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 ...
Fattening farm's biomass as potential in cogeneration system / Tečni stajnjak kao potencijal stočarskih farmi u sistemu kogeneracije
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2006)
Biomass is specific energetic resource, because of a possibility of getting heat, electricity, fuel etc. This kind of energy contribute to higher labor employment, reduce emission of SO2, CO2, NO2, comparing to other fossil ...
Choice of aggregate for deep tillage in the establishment of orchards / Izbor tma za duboku obradu zemljišta pri podizanju višegodišnjih zasada
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2006)
The choice of the appropriate aggregate for deep tillage is an issue of major concern in the technology of orchard establishment. Conventional technologies include trenching or sub soiling used to improve the mechanical ...
