Uticaj različitih varijanti đubrenja na parametre prinosa kod ozime pšenice

Abstract

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). Ogled je obuhvatao kontrolu i šest varijanti mineralne ishrane. Doza upotrebljenog azota je bila 120 kg N/ha, koja je primenjivana pojedinačno i u kombinaciji sa dva nivoa fosfornih đubriva. Ispitivanja su pokazala znatno variranje prinosa zrna u zavisnosti od mineralne ishrane. Najviši prinos zrna od 3,662 t/ha dobijen je sa primenom NPK u količini od 120 kg N/ha, 100 kg P2O5/ha, 60 kg K2O/ha. Upotrebom N i P u količini od 120 kg N/ha, 60 kg P2O5/ha postignut je najveći efekat na masu 1000 zrna (43,10 g), dok je najveću hektolitarsku masu imala varijanta P1 (73,59 kg/hl).

Studies were conducted in a stationary field trial with fertilization, on the vertisol soil type in process degradation. Examination carried out on soil which characterized low pH value (pH<5.0). The six variants of mineral nutrition and control (without nutrition) were included in experiment. The rate of nitrogen was 120 kg N/ha that were applied individually and by combination with two level of phosphorus fertilizer. Investigation where showed a considerable variation of grain yield in dependence from mineral nutrition. The highest yield of 3.662 t/ha gave the application of the NPK in an amount of 120 kg N and 100 kg of P2O5 and 60 kg K2O. The use of N and P in the amount of 120 kg N and 60 kg P2O5 made the biggest impact on the 1000-grain weight (43.10 g), while the highest test weight had a variant of P1 (73.59 kg/hl).
