Abstract


In the present experimental work was investigated the influence of mineral fertilizers, produced by Agropolychim JSC, on the main agrochemical parameters of the soil, as well as on the productivity and biochemical characteristics of two of the main winter crops in our country - wheat (“Andino” variety) and rapeseed (“PT225” hybrid). The study found a beneficial effect of the urea + ammonium nitrate and UAN variants on the macronutrient reserve in wheat, while the use of liquid nitrogen fertilizer UAN had the highest effect in rapeseed. The highest productivity in the experiment with wheat and especially rapeseed demonstrates the variant using liquid nitrogen fertilizer UAN, with the difference in yield compared to the other variants statistically proven.
