CROP ROTATION OPTIMIZATION ON THE CHECHEN REPUBLIC SLOPE LANDSCAPES

Abstract

Optimization of crop rotations of grain specialization is currently an urgent task in the light of modern economic realities. In this regard, experiments were conducted on the slope landscapes of the Chechen Republic, in which four crop rotations and two plots with permanent crops of winter wheat and spring barley were studied. Studies of crop contamination, crop structure, grain yield from a unit of crop rotation area have shown that the most optimal crop rotation is a five–field grain–pair crop rotation: black steam – winter wheat - spring wheat - peas - spring barley. The yield of grain per unit of crop area in this crop rotation was 56-57% higher than in the first variant, 37-39% higher than in the second variant, 36-37% higher than in the third variant, 13-14% higher than in the fourth variant, 4-5% higher than in the fifth variant and it was equal to 2.79 t/ha on a sloping landscape.
