Abstract

The analysis of the features of the leaf area formation and photosynthetic productivity of crops chickpeas in a desert zone Balkhash. The correlation between the time of sowing, sowing methods and seeding rate and leaf area, net photosynthetic productivity and accumulation of dry weight. The analysis of the features of formation of leaf area and photosynthetic productivity of crops chickpeas in a desert zone Balkhash. The correlation between the time of sowing, sowing methods and seeding rate and leaf area, net
photosynthetic productivity and accumulation of dry weight. It was found that the fundamental requirement of high photosynthetic productivity of chickpea under Akdalinski array of rice cultivation is sowing when the soil temperature at the depth of 10 cm 8 - 100 C. Rationality of crop density, with an area of 17.1 thousand leaves m 2 /ha seeding provides a width of 30 cm between rows and seeding rate of 400,000 viable seeds per hectare, and the application of mineral fertilizers N80R20 is certainly reception.
