Abstract

In order to evaluate yield and yield components properties of cold-tolerant chickpea under winter sowing and complementary irrigation conditions, two experiments in the context of partial balanced block design with 81 chickpea genotypes and three replications were carried out. Complementary irrigation was performed during growing season including irrigation immediately after sowing, 20 days after the first irrigation and at early phase of flowering. After winter cold, survival percentage of the chickpea genotypes was calculated and total precipitation rate from sowing to harvesting was 267 mm. Moreover, properties of grain yield components (survival percentage, pod number per plant, the number of grains per pod and weight of 1000 grains), grain yield, biological yield and harvest indices of the genotypes were measured and recorded. Based on the results, the difference between the genotypes was significant for all the measured properties. Under complementary irrigation, 40 percent of the genotypes showed winter survival rate higher than 76 percent and grain yield in 52 percent of the genotypes was higher than 100gr/m². Under winter sowing condition, grain yield in 32 percent of the samples was higher than 40gr/m². Finally, under winter sowing and complementary irrigation regime, the genotypes ‘MCC333’, ‘MCC186’, ‘MCC803’ and ‘MCC743’ possessing yield over 600 kg/ha were determined as the superior genotypes.
