Study of the rainfed chickpea (Cicer arietinum L.) cultivars response to planting dates in Kermanshah conditions
Abstract:   (4216 Views)

This study was performed in order to evaluate the effect of different sowing dates on yield and yield components. Treatments were three sowing dates such as (Nov11, Nov22 and Dec1) and four chickpea cultivars (Hashem, Azad, Arman and ILC482). Results showed that the interaction effect of cultivar×sowing date was significant on all traits. The results indicated that the highest height of plant was related to Azad cultivar in the first and third sowing dates. Moreover, in the second sowing date, the highest height of the plant was related to Arman cultivar. in Nov11and Dec1 planting date Azad cultivar and in Nov22 sowing date Arman cultivar had the highest plant height. Maximum plant height (54.1 cm) was recorded for Arman cultivar at the second sowing date and minimum plant height (25.7 cm) was recorded for Hashem cultivar at the first planting date. Hashem cultivar had the highest biomass and number of main branch per plant at second sowing date. Also, the maximum number of seeds per plant (44) was recorded in ILC482 at second sowing date and maximum 100 seed weight (29.2 g) was recorded for Azad cultivar at the second and third sowing dates. In the first and second sowing date Hashem cultivar and in the third sowing date Azad cultivar had the highest seed yield. Maximum seed yield (2490 kg.ha-1) was Hashem at second sowing date and maximum seed yield (1260 kg.ha-1) was observed for this cultivar at third sowing date and was 49.3% less than second sowing date. In ILC482 maximum seed yield was obtained for the second sowing date.  Based on the results of the present study to achieve the highest seed yield in Kermanshah condition Hashem cultivar could be cultivated at the second sowing date.
