Forming of cropping capacity against the background of effect and aftereffect of diatomaceous earth and poultry manure

Abstract

The effect of poultry manure, different rates of diatomaceous earth in the combination with poultry manure on the elements of the yield structure and productivity of a hybrid of Ladoga 175 MV corn and Granny spring wheat was studied. It was stated that the most significant effect on the positive change in the elements of the structure of the yield of corn and spring wheat had a direct effect and aftereffect of diatomaceous earth in combination with poultry manure. The maximum productivity was ensured by the integrated use of diatomaceous earth with poultry manure. The productivity of corn against their background statistically exceeded the control by 2.02-2.52 t/ha of grain units or by 47.7-59.6 %, the productivity of spring wheat – by 0.66-0.87 t/ha of grain units, or 26.8-35.4%. The effect and aftereffect of diatomaceous earth with rates 8 and 10 t/ha both pure and in a complex with poultry manure had an equivalent effect on the productivity of corn and spring wheat.
