The impact of the joint application of mineral and organic fertilizers on the development and productivity of corn

The role of macro- and micronutrients for corn plants is great. They increase the intensity of photosynthesis, participate in biological processes. The work is devoted to the development of science-based methods for increasing the yield and quality of corn. Field experiments were conducted in the northwestern zone of Azerbaijan. Test sites were laid in 4-fold repetition, in 6 versions. Used: ammonium nitrate, simple superphosphate, potassium sulfate, manure, compost of various waste products. All agricultural activities were carried out according to the developed technology. Before ploughing, the entire rate of manure, phosphorus and potassium was introduced, in early spring before tillage. As a result, it was revealed that with the introduction of 20 t/ha of compost - the yield of corn was 85.1 c/ha, i.e. an increase of 15.9 c/ha. It can be concluded that mineral fertilizers in combination with manure in the proportions chosen by the authors effectively affect not only the growth and development of plants, corn productivity also increases.
