GRANULAR BIRD DROPPINGS - EFFECTIVE A WAY TO INCREASE THE PRODUCTIVITY OF AGRICUTURAL CROPS

Abstract

The article presents the results of field studies on the study of the effect of different doses of granular manure on the formation of spring wheat productivity, conducted in a separate subdivision of the Ramzai educational and experimental farm of the Penza State Agrarian University (Penza region, Mokshansky district) in 2022-2023. The studied granular manure was characterized by a nitrogen content of 4.0-4.5%, phosphorus 3.0-3.5%, potassium 4.0-4.5%, organic matter 40.0-42.0%. The research results show that the spring application of granular fertilizers from manure in doses from 500 to 2000 kg /ha significantly increases the number of grains in the ear and the weight of grain from one ear, which led to an increase in the yield of spring wheat grain by 12.6-36.7%. Studies have shown that the studied doses of manure increase not only the yield of spring wheat grain, but also significantly increase its quality. Protein content increased by 0.67-1.49%, gluten by 1.8-5.0%. The yield, protein and gluten content in the grain increased directly proportional to the application doses.
