Abstract

A study was conducted during rabi 2012-13 at Pulse Research Area of CCS Haryana Agricultural University, Hisar to evaluate the effect of sowing time and seed rate on nodulation of chickpea cultivars. The experiment was laid out in a split plot design with two sowing time (1st fortnight of November and 1st fortnight of December.) and four cultivars (H09-23, H08-18, C-235 and HC-1) kept in main plots while three seed rates viz. 40 kg ha-1, 50 kg ha-1 and 60 kg ha-1 were kept in subplots and replicated thrice. Higher value of dry weight of nodule at 60 and 90 DAS was recorded in early sown as compared to late sown chickpea. Among various chickpea cultivar H09-23 recorded highest number of nodules per plant at both the stages. Varying seed rate of chickpea cultivars fail to influence numbers of nodules and its dry weight.
