Response of Winter Wheat (Triticum aestivum L.) to Fertilizers with Nitrogen-Transformation Inhibitors and Timing of Their Application under Field Conditions

Winter wheat is a widely cultivated crop that requires high inputs of nitrogen (N) fertilization, which often connected with N losses. The application fertilizers nitrification (NI) and urease inhibitors (UI) an opportunity to eliminate the risk losses improve availability plants. aim this study compare effect conventional containing nitrogen-transformation as well evaluate timing their on wheat-grain yield quality under conditions three-year field experiment. examined were applied in single dose or split combination fertilizers. urea NI and/or UI resulted relatively average increase grain yield, while protein content Zeleny-test values significantly increased compared application. more significant was found moisture-rich drier conditions. A (by 6.3%) value 16.5%) observed after inhibited comparing control treatment (without inhibitors).
