abstract
A research study was performed during rabi/summer 2023-24 at Agricultural Research Station, Adilabad to identify suitable chickpea variety(s) to be cultivated under late sowing environment in cotton-based cropping system based on growth, yield and economical parameters. The study was conducted in strip plot design in three replications with varieties as horizontal factor viz., NBeG-119, NBeG-810, NBeG-857, JG-14 and JAKI-9218; varied growing environments as vertical factor viz., December 1^st week, 2023; December 3^rd week, 2023 and January 1^st week, 2024. The outcome of experiment showed that JG-14 recorded higher seed yield (2564 kg ha^-1) and biological yield (7672 kg ha^-1) analogous to NBeG-857 (7558 kg ha^-1). Plant height and dry matter were higher for NBeG-810 (46.1 cm and 4036 kg ha^-1 respectively) but equivalent with JG-14 (42.5 cm) for plant height at harvest stage. Lower yield was recorded with NBeG-119. Among growing environments, December 1^st week obtained higher plant height (44.9 cm), dry matter (3817 kg ha^-1), seed yield (2234 kg ha^-1) and biological yield (6697 kg ha^-1) all being on par with December 3^rd week except biological yield. Lower growth and yield were registered from January 1^st but were comparable with December 3^rd week. The cultivar JG-14 (2.20) among varieties and December 1^st week (2.03) among growing environments resulted in higher B:C ratio analogous with December 3^rd week.
