Efficiency of application of granulated organic fertilizers based on chicken manure in the cultivation of spring wheat

Abstract

The construction of modern poultry farms has significantly increased the proportion of bird droppings in the total production of organic fertilizers. Due to the high concentration of poultry farms on the territory of the Mari El Republic, the need has arisen to search for and scientifically sound introduction of new technologies that are not traditional for our zone of fertilizers, techniques and methods of growing crops based on agricultural biologization in order to significantly reduce the chemical load on the soil. One of the methods to improve soil fertility is the use of granular organic fertilizers based on bird droppings. We conducted studies on the use of GOF based on chicken droppings in the cultivation of spring wheat. Studies have shown that the use of granular organic fertilizers contributed to a significant increase in spring wheat yields. The highest value was observed for the option with the introduction of GOF at a dose of 400 kg/ha, and amounted to 2.18 t/ha, which is 34.6% higher than the option without fertilizers. It should be noted that the use of GOF based on bird droppings contributed to the reduction of root rot susceptibility of spring wheat, the smallest spread and development of root rot was in the variant with 400 kg/ha - 44.7% and 24.1%, which is 28.8% and 41.4% less than in the variant without fertilizers.
