Abstract
- This study aims to analyze the evolution of winter wheat production, between 1996 and 2018, under the influence of 25 fertilization combinations with nitrogen and phosphorus. Nitrogen fertilizers applied have graduations of 0,30,60,90 and 120 kg active substance/ha, and of phosphorus 0, 40,80,120 and 160 kg of active substance/ha. The research carried out on a typical chernozem in the West of Romania showed that the fertilizers are well used by the winter wheat crop. During the 1996-2018 period, the influence of chemical fertilizers with nitrogen and phosphorus has been studied in a 3 years rotation (soya bean-wheatmaize). Unilateral application of nitrogen and phosphorus bring production increases within the range 573 kg grains/ha - 1016 kg/ha, nitrogen and 282 kg grains/ha - 998 kg/ha, phosphorus. The obtained results highlight the fundamental role of the combined application of the two types of fertilizers. The optimal dose of fertilizer, from an economic point of view is N88P122, with a production of 6866 kg wheat/ha. [ABSTRACT FROM AUTHOR]
