INFLUENCE OF THE NORMS OF FERTILIZERS AND THE NUMBER OF IRRIGATIONS ON AGROPHYSICAL INDICATORS OF SOILS AND QUALITATIVE INDICATORS OF FODDER OBTAINED FROM MIXED CROPS Ph.D., As. Pr. Ibrahimov A. Q., Ph.D., As. Pr. Huseynov M. S., Ph.D., As. Pr. Allahverdiyev E. R. Azerbaijan, Ganja, Azerbaijan State Agrarian University Abstract. The article is devoted to the study of the effect of optimized norms of fertilizers and irrigation amounts on the qualitative indicators of feed grown from mixed crops and the water and physical properties of the soil in conditions of sierozems in the territory of the municipality of Hindarkh in the Agjabedi district. As a result of analyzes, the content of crude protein, absolute dry matter, nitrate nitrogen in dry matter, yield of feed units per hectare and digestible protein was determined. During the study it became known that if in the control without fertilizers in dry weight, the raw protein was stored 5.4%, dry matter 21.5%, nitrate - 61 mg/kg, then with the application of fertilizers in the norm N 120 P 150 K 150 , these indicators were respectively 6.3%, 25.5% and 82 mg/kg, and with the application of organic and mineral fertilizers, a norm of 10 t/hec manure + N 40 P 95 K 60 -, respectively, 6.1%, 26.3% and 75 mg/kg. These values were much less than the maximum limit for the soluble level for fodder crops (200 mg/kg). And this proves that the crop produced is environmentally safe. In the experiment, the yield of feed units and the amount of digestible protein was determined. So, if in the control without fertilizers the yield of feed units was 8225.2, digestible protein 734 kg/hec, with the variant with the fertilizer norm N 120 P 150 K 150 , these figures were respectively 12891.5 and 1151.1 kg/hec, in the version using 10 t/hec of manure + N 40 P 95 K 60 - 12134.6 and 1083.4 kg/hec, and this is a significant increase in comparison with the control without fertilizers. Thus, the use of fertilizers in the optimal rate and the correct and timely irrigation norms significantly improves the quality of the crop in mixed crops. At the end of the study, we conclude that, when using fertilizers, the water-physical properties of the soil (volume mass, total porosity, Moisture reserves). Keywords: fertilization, irrigation, stubble, mixed crop, qualitative yield indicators, agrophysical features of the soil. The main task facing the modern farming system is the rational use of land, preventing it from pollution and degradation, developing agrotechnologies in the direction of restoring and improving soil fertility.
