Sumario:The article presents the results of four-year studies on the influence of various combinations of the seeding rate and row-spacing width on plants productivity and grain cropping capacity of chickpea varieties in the conditions of Eastern Forest-Steppe of Ukraine. The highest productivity of chickpea plants of Budzhak and Odyssey varieties was formed on variants with the lowest seeding rate in combination with 15 cm row-spacing. In this variant plant nutrition area was close to the square with the sides ratio 1.0:1.1. At the same time, through the smaller number of plants per unit of area, the grain yield in this variant was significantly inferior to the variants with a higher seeding rate. Two better combination of the seeding rate and row-spacing width were distinguished which ensure the formation of the highest cropping capacity of both chickpea varieties. This is combination of 800 thousand pieces/ha seeding rate with 15 cm row-spacing and 700 thousand pieces/ha seeding rate with 30 cm row-spacing. On mentioned variants, the grain yield of Budzhak variety was 2.34 and 2.44 t/ha respectively, and the grain yield of Odyssey variety ‒ 2.61 and 2.51 t/ha.
