Influence of seeding methods on the duration of the growing season and productivity of chickpea varieties

A. Dobrovolsky Oleg Kovalenko L. Andreychenko N. Koloyanidi

The results of experimental research and production testing of mid-season chickpea varieties in conditions of Southern Steppe of Ukraine are presented. The longest growing season – 108–113 days was observed with a widerow sowing method, and the shortest – with solid sowing crops (101–108 days). Correlation analysis showed a strong positive relationship between the duration of the growing season and the average daily air temperature during the growing season of chickpea (r = 0.89). Precipitation and Sielianinov’s hydrothermal index (r = 0.73 and r = 0.75) had a great influence on the formation of the grain yield of chickpea, and the average daily air temperature (r = 0.80) had an effect on the accumulation of protein in the grain.
