Ispitivanja su izvedena na stacionarnom poljskom ogledu sa
đubrenjem, na zemljištu tipa vertisol u procesu degradacije. Zemljište na kome je ogled izveden odlikuje se niskom pH vrednošću (pH<5,0). Doza upotrebljenog azota je bila 80 kg N/ha, koja je primenjivana u kombinaciji sa fosfornim i kalijumovim đubrivom. Ispitivanja su pokazala znatno variranje prinosa zrna.
Najviši prinos zrna sorta Planeta ostvarila je primenom NPK u količini od 80 kg N ha-1, 100 kg P2O5 ha-1 i 60 kg K2O ha-1 (4,827 t ha-1). Analizom varijanse ustanovljene su statistički visoko značajne razlike za prinos zrna između ispitivanih varijanti đubrenja.Tests were carried out on stationary field trial, soil type vertisol in
the process of degradation. The land on which the view is derived is characterized by low pH (pH<5.0). Dose of nitrogen was 80 kg of N ha-1, which was administered in combination with phosphorous and potassium fertilizer. The tests showed a significant grain yield. The highest grain yield had variety Planeta
application of NPK in a quantity of 80 kg N ha-1, 100 kg P2O5
ha-1 and 60 kg K2O ha-1 (4.827 t ha-1). Variance analysis showed statistically significant differences for grain yield between the variants of fertilization
