U ogledu je ispitivan uticaj sistema obrade zemljišta i nivoa đubrenja azotom na visinu i kvalitet prinosa zrna kukuruza. Hibrid ZP 606 je gajen na oglednom polju Instituta za kukuruz Zemun Polje, tokom 2016-2018. uz primenu konvencionalne, redukovane (obrada rotofrezom) i nulte (direktna setva) obrade zemljišta i 0, 120 i 240 kg azota ha-1. U pogledu meteoroloških uslova, godine ispitivanja su se vrlo razlikovale. Prinos zrna je bio najveći na površini sa konvencionalnom obradom zemljišta i primenom azota u najvećoj količini (9,57 t ha-1) kao i sadržaj proteina, karotenoida, fitinskog fosfora, glutationa i fenola dok je sadržaj skroba, ulja, tokoferola i neorganskog fosfora bio veći na površinama sa manje intenzivnom obradom i đubrenjem. .
The experiment studies the effect of tillage systems and levels of nitrogen fertilization on the amount and quality of grain yield. Hybrid ZP606 is grown on the experimental field of the Maize Research Institute Zemun Polje, during 2016-2018, with the use of a conventional, reduced ( rotovator ) and no - till ( direct drilling ) of soil treatment and 0, 120 and 240 kg N ha-1. In terms of weather conditions, the years of investigation varied in great extent. Grain yield was the largest in the conventional tillage and application of nitrogen in the largest quantity ( 9,57 t ha -1) as well as the content of proteins, carotenoids, phytic phosphorus, glutathione and phenols, while the content of starch, oil, tocopherols, and inorganic P was higher on the surface of less intensive tillage and fertilization.
