Abstract: High temperature is an important factor affecting chickpea growth, development and grain yield. Understanding the plant response to higher temperature is a key factor genotype selection for reproductive efficiency in chickpea. Under 48th SMW date of sowing (D3) seed yield per plant recorded positive association with pod number per plant, pod weight per plant, total flower produced, total dry matter per plant, test weight and harvest index (0.854**, 0.993**, 0.404**, 0.780**, 0.414** and 0.617**, respectively). The degree of association for seed yield was higher in 48th SMW compared to 41st, 44th and pooled dates of sowing. The total flower production and pod number decreased from D1 to D3 and this decrease was attributed to flower abortion due to higher temperature coincided with flowering period. Harvest index recorded positive association with pod number per plant, pod weight per plant and total flower produced (0.610**, 0.616** and 0.462**, respectively) under 48th SMW. However, seed yield per plant was significantly and negatively associated with flower to pod ratio under 41st, 44th, 48th, SMW and pooled date of sowing. Further, total flower count recorded positive association with flower to pod ratio, harvest index and seed yield (0.354**, 0.462** and 0.404**, respectively). This suggested that number of flower produced is not only dependent on total dry matter but also on maximum and minimum temperature. The experiment revealed that dates of sowing place an important role in determining dry matter accumulation and flower production in chickpea.
