An experiment was conducted during rabi (winter) season of 2015 to access the effect of changing environment on growth and yield of chickpea (Cicer arietinum L.). The experiment was conducted with nine treatment combinations comprised of three growing environment viz., sowing on Oct.25th with temperature 240C, Nov.4th with temperature 21.50C and Nov.14th with temperature 180C and three varieties viz, Avarodhi, Uday, and PG-186. Sowing temperature (240C) on Oct.25th produced significantly higher growth yield attributes and yield due to fulfillment of suitable thermal requirement for various plant processes. High temperature during-reproductive stage adversely affected the number of pods plant-1and seed pod- 1 in late sowing (Nov.14th) which ultimately result the lowest seed yield. Delay in sowing reduced the average temperature. Heat use efficiency (0.62 gm-2 0C day-1)and radiation use efficiency (1.6 g/MJ) was recorded high when sowing was done on Oct.25th with temperature 240C followed by sowing done on Nov.4th with lowest heat use efficiency and radiation use efficiency with the sowing temperature of 180C. Avarodhi cultivar was found more conducive and remunerative for growth development seed yield radiation use efficiency and heat use efficiency.
