Mechanized harvesting of leafy parsley crops in the region of South Banat / Mehanizovana berba peršuna u regionu Južnog Banata
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2013)
So far, many types, styles and sizes of mowing equipment has been developed and introduced in the agricultural practice. Therefore, leaf crops harvesting seems to be easier to mechanize with respect to other cultivars. ...
A chaotic profit growth model in the agricultural machines production / Haotični model rasta profita u proizvodnji poljoprivrednih mašina
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2012)
The basic aim of this paper is to provide a relatively simple profit growth model in the agricultural machines production that is capable of generating stable equilibria, cycles, or chaos. A key hypothesis of this work is ...
Using the glass fibres in recycling agricultural plastic waste / Korišćenje staklenih vlakana pri reciklaži plastičnog otpada iz poljoprivrede
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2013)
The wide-spread presence of plastic material in municipal and agricultural waste has significantly raised the ecology concern in Europe leading to laws and regulations aimed at controlling and reducing waste production, ...
Effects of mechanized method of liquid fertilizer application in corn production / Efekti mehanizovanog načina aplikacije tečnog startnog đubriva u proizvodnji kukuruza
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2012)
Conventional corn production assumes usage of standard inorganic fertilizers which can be added to the soil by different methods. Unlike conventional production, this research was conducted with assumption that by using ...
Effects of irrigation on yield and composition of principal elements of nutrients in maize-growing soil / Uticaj navodnjavanja na prinos i sadržaj glavnih elemenata ishrane u zemljištu pod kukuruzom
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2012)
Extensive organic production under irrigation conditions requires greater amounts of NPK fertilisers. Furthermore, the mobility of fertilisers, especially of nitrogen, is greater under the increased soil moisture content, ...
