Studies on Dynamics of Growth Pattern in Chickpea and Their Correlations to Seed Yield under Different Sowing Dates in North– West India

The experiment was conducted with ten genotypes of chickpea (Cicer arietinum L.) viz ICCV 88503, ICCV 92944, HC- 1, HC-3, HC-5, H12-64, H13-01, H13-02, H14-01 and H14-04 for three dates of sowing i.e 15th October, 15thNovember and 15thDecember at the field in randomized block design during Rabi season of 2017-18 and 2018-19 at Pulses Section, Chaudhary Charan Singh Haryana Agricultural University, Hisar to observe the effect of sowing dates on vegetative and reproductive growth rate of chickpea genotypes at different intervals i.e 30, 60, 90, and 120 DAS with their correlations to seed yield. The dry weight of leaves, stem, pods, plant height, crop growth rate, relative growth rate and pollen viability were minimum in 15thDecember sowing and maximum in 15thOctober sowing at all intervals. Among genotypes, maximum dry matter and growth rate were observed in H12-64 and H13-01 while minimum were found in H14-04. Seed yield exhibited significant positive correlation with all traits in 15th October and 15th November sowing while non-significant was on 15th December sowing.
