Abstract: A field experiment was conducted during 2013-14 at Main Agriculture Research Station, University of Agriculture Sciences, Dharwad to assess productivity of chickpea genotypes. The experiment consisted of three genotypes (Annigeri-1, JG-11 and JG-14) with five dates of sowing (from 40th to 48th standard week) laid out in a factorial RBD design. Among all the dates, significantly higher plant height, primary and secondary branches were recorded under D3 temperature regime (44th standard week sowing). All the phenological parameters like number days to 50% flowering, pod initiation, physiological maturity were significantly more with optimum growing degree days, phenol-thermal index and heat use efficiency under D3 temperature regimes. Flower production per day per plant and per cent pollen sterility was also differed significantly, where the number of flowers were produced more under D3 temperature regimes but at the same time it shows maximum per cent of sterile pollens (60%) under the minimum temperature of (9.7oC). Pollen viability reduces as temperature reduces 5-10oC. The TDM and its distribution, biochemical parameters (SPAD and RWC) growth parameters (leaf area, LAI, LAD, AGR, CGR, RGR and NAR) recorded significantly under D3 temperature regime. Yield and yield attributes like, number of pods, seeds, seed weight, haulm weight per plant, test weight, HI and seed yield was significantly maximum along with optimum total number of flowers and flower to pod ratio under D3 temperature regime (44th standard week of sowing). Among the genotypes, JG-14 is best performer under D3 temperature and delayed sowing, which shows higher plant height, TDM, chlorophyll content, test weight and early flowering, less flower to pod ratio and optimum yield (q ha-1) with less pollen sterility (%) with short duration of 80-95 days. Chickpea productivity under D3 temperature regime (44th standard week) was best date of sowing for getting a good yield.
