On The Evaluation of The Effect of Soil and Fertilizer Treatment on The Cultivation of Cereal Crops

Abstract

The article gives the results of studies of the effect of soil treatment and fertilizers on the productivity of winter wheat in the Ganja-Gazakh area of Azerbaijan. The positive effect of fertilizers on winter wheat plants is manifested only in well-cultivated soils with an environmental reaction close to neutrality. At the same time, it is proven that between the intensity of the application of mineral fertilizers and the productivity of cereal crops in the world, a close direct dependence is established. Therefore, the highest grain yield here was obtained in the manure variant 10t/ha + N90P90K60 57.1 c/ha, an increase of 24.3 c/ha or 74.1%, where the 40-50% yield increase is due to the application of fertilizers.
