PHOTOSYNTHETIC ACTIVITY OF BEAN ORDINARY DEPENDING ON WAYS OF SEEDING

Abstract

This article studies the influence of sowing methods, schemes, and norms on the formation of leaf area and on the net productivity of photosynthesis of new varieties of common beans. Studies have shown that in variants with high density of standing, the area of leaves on one plant is reduced. The reason for the decline in this indicator is associated with high competition of plants. But on one hectare, this indicator increases due to a larger number of plants. In variants with a low sowing rate per hectare, the leaf area decreases, but in one plant it increases. Studies have also shown the dependence of the net productivity of photosynthesis on sowing methods. An increase or decrease in the seeding rate and a change in seeding methods negatively affect this indicator.
