Photosynthetic activity of the barley of various biological groups depending on sowing terms and seeding rate

Abstract

The article describes the results of studies on the indicators of photosynthetic activity of barley of various biological groups, depending on sowing terms and seeding rate in the conditions of dry land of the steppe part of the Crimean peninsula. Analysis of the obtained data showed that the leaf surface area, photosynthetic potential and net productivity of photosynthesis of barley plants change under the influence of the studied agrotechnical factors and their increase contributes to an increase in yield. The size of the crop is most influenced by the leaf surface area. An increase in this indicator has a positive effect on the potential yield.
