(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2019)
At the current level of technological development, it is widely accepted that survival and progress of modern agricultural technology (among other things) is based on the widespread application of electronically controlled ...
Mechanized pruning of plums / Mehanizovana rezidba šljive
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2007)
The paper presents the results of the two-year long experiments with mechanized plum pruning of cv Stanley with hydraulic pruner HR-85 powered by tractors Rakovica 65 and Torpedo TD 75A. The results suggest that mechanized ...
Hydraulic symbols: Part three: Valves / Hidraulički simboli - deo III - ventili
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2019)
Similar to human health, the importance of hydraulics sometimes becomes apparent only in her absence. Images and motives of agricultural workers from the past times and centuries can look attractive only on paintings of ...
Long term effects of the application of ameliorative tillage systems on heavy mechanical composition soils in crop production / Efekti produženog dejstva primene meliorativnog sistema obrade zemljišta teškog mehaničkog sastava u proizvodnji ratarskih kultura
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2012)
There are around 400,000 hectares of soils with heavy mechanical composition, and the greatest part of the production area is under crops. The long term soil tillage by conventional methods (using plough) and a large number ...
Distribution of airborne dust particles in a tied-cows barn / Raspodela prašine u vazduhu staja za držanje krava
