Influence of seeding methods on the duration of the growing season and productivity of chickpea varieties 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 wide-row 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. Keywords: chickpeas, meteorological conditions, growing season, productivity, variety, seeding method.
