Development of the main elements of the crop structure of pea and chickpea at different rates and methods of seeding under the conditions of the steppe Crimea

Abstract

In this article, we present research results on studying the effect of rates and methods of seeding on the seed productivity of new cultivars of pea (Pisum sativum L .) and chickpea (Cicer arietinum L. ) under conditions of the Crimea. The field trials were conducted during the period 2016-2018. Studies have shown that the optimum seeding rate for the pea cultivar Pharaoh (leafless morphotype) was 1.2-1.4 million pieces per hectare. The best seeding rate for the chickpea cultivar Zolotoy Yubiley both under closely spaced rows (15cm) and wide-row sowing with the 45 cm row-width spacing was 400 thousand seeds per hectare, and under wide-row sowing with the 60 cm row-width spacing was 200 thousand seeds/ha. For the cultivation chickpea Zolotoy Yubiley, the most productive was the wide-row sowing with the 45 cm row-width spacing because the yield, in this case, was 1.23 t/ha.
