Abstract:
A field experiment was conducted to study the responses of chickpea types on growth, yield and economics under different thermal environment and irrigation levels during rabi seasons of 2017-18 and 2018-19 at Research Farm, Department of Physics and Agrometeorology Jawaharlal Neharu Krishi Vishwa Vidyalaya, Jabalpur (Madhya Pradesh). The experiment was laid out in split split-plot design with three replications consisted of three sowing dates viz., November 15^th, December 1^st and December 15^th, three chickpea types viz., JG 14 (Deshi), JGG 1 (Gulabi) and JGK 1 (Kabuli) with three irrigation levels (No irrigation, Irrigation at 50% branching and two irrigation each at 50% branching and pod development) as main plot, sub-plot treatments and sub sub-plot, respectively. Results revealed that Plant height, number of branches, number of filled pods, 100 seed weight, seed yield, Stover yield and harvest index decreased with successive delay in sowing. December 1^st sowing produced significantly higher plant height, number of branches, number of filled pods, 100 seed weight, Seed yield (2090.08 kg ha^-1), Stover yield (2832.85 Kg ha^-1), harvest index (45.55%), net income (Rs 61247.80 ha^-1) and B:C ratio (2.50) as compared to November 15^th and December 15^th. Among cultivars, seed yield (1959 Kg ha^-1) and harvest index (43.54%), Net monitory return (Rs 54948.22 ha^-1) and B:C ratio (2.35) were found maximum in JG 14 (Deshi) chickpea type. Irrigation each at 50% branching and pod development stages is produced maximum seed yield (2034.81 kg ha^-1), Stover yield (2733.84 Kg ha^-1),harvest index (42.60%),net income (Rs 57965.76 ha^-1) and B:C ratio (2.39) over no irrigation and one irrigation at 50% branching.
