Photosynthetic activity of spring barley plants depending on moisture provision
The technology of cultivation of malting barley is distinguished by a number of features associated primarily with the task of obtaining high-quality raw materials for the processing industry. As the objects of research, varieties of spring barley, Viscount and Mamluk, were used that were approved for use in the North Caucasus region. The aim of this work was to study the formation of photosynthetic activity of spring barley plants depending on the seeding rate and moisture level during the year, which is important to increase yield and grain quality. Studies have shown that the size of the leaf surface, dry weight, photosynthetic potential, and net productivity of photosynthesis significantly affected by the seeding rate and soil moisture during the growing season. The authors have the best indicators of these characteristics in the Viscount variety, with a seeding rate of 5.5–6.0 million viable seeds per hectare in 2017. On this showing this option is 7-8% more than other version.
