Abstract
One of the main measures to increase production in the field of grain and feed production in our republic is to increase the yield of grain and forage crops on plantations.The purpose of our research work is to study the effect of fertilization and irrigation rates on the yield, crop quality and soil fertility of crops sown in a mixture when planting honeysuckle. The results of research conducted in world agriculture show that mainly the yield and composition of mixed crops, the quality indicators of which depend on the components of the crops to be sown, their seeding rate and cultivation technology. As a result of studies conducted in the conditions of ancient irrigated gray-meadow soils of the Karabakh region of our republic, it was found that with 4 - fold vegetation irrigation (4200 m3), the yield of mixed sowing in the control version without fertilizers was 372 c/ha, while under the influence of mineral and organic mineral fertilizers, the yield increased and amounted to 447-627 c/ha. Based on the results of the study, it can be said that in order to obtain a high yield of green mass with the joint sowing of corn and soybeans, the optimal irrigation and fertilizer application rates were determined, the highest indicator was achieved in the variant where the fertilizer standards N120P150C150 were applied. In the course of the study, the influence of fertilizer application rates and optimization of the amount of irrigation on the quality indicators of feed, as well as on the yield obtained from mixed crops, was studied. As a result of the conducted analyses, the amount of raw protein, absolute dry matter, nitrate nitrogen in the natural mass, the yield of feed units per hectare and the amount of protein going for digestion were determined. Thus, the application of fertilizers within the optimal limits and the correct, timely supply of irrigation standards significantly increase the quality of the crop on a par with the yield on mixed crops, the soil fertility is preserved.
