Abstract
The article presents the results of studies for 2016-2018 years about the effect of seeding rates and seeding methods on the chickpea plant leaf area formation. It was established that the studied technological factors influenced the formation of the chickpea plants assimilation surface. During the flowering phase, the leaf surface area of chickpea plants was the largest and ranged from 10.32 to 16.03 th. m2/ha in the Budjak variety and from 10.68 to 17.15 th. m2/ha in the Odyssey variety. In all the studied phases of plant growth and development, the pattern of leaf area variability, depending on the seeding rates and sowing methods, was maintained in the experiment. Assuming the row spacing extension from 15 cm to 45 cm, a decrease the chickpea plants assimilation surface in all phases of the measurements was noted. This index decreased to a greater extent with the expansion of the row spacing from 30 to 45 cm, than from 15 to 30 cm. In the variants of the row sowing method with a 15 cm row spacing and a seeding rate of 0.9 million psc / ha the maximum values of the chickpea plants assimilation surface in both varieties were noted.
