Abstract
The study was conducted at Department of Agricultural Meteorology, CCS Haryana Agricultural University to assess the effects of sowing dates and genotypes on chickpea yield using CROPGROW- chickpea (DSSAT v 4.7) model for western Haryana. Thus three varieties of chickpea i.e. HC 1(V1), HC 7(V2) and HC 5(V3) each sown at four different dates of sowing i.e. 13th October (D1), 1st November (D2), 15th November (D3) and 2nd December in split plot design was replicated thrice. Maximum accumulated PAR was recorded for the crop sown on D1 at physiological maturity stage and least accumulation was recorded in D4. Variety HC 7 recorded maximum value of intercepted PAR while lowest value was recorded in HC 1 Delay in sowing time resulted in decrease in seed yield. Maximum seed yield was shown by the crop sown on D1 followed by D2, D3 and D4. Significant variation was shown in seed yield by among the varieties. Maximum seed yield was recorded in variety HC 7 while least value was recorded in variety HC 1. Simulated seed yield was in good agreement with the observed values of seed yield. Mean observed seed yield varied between 1177 kg/ha (D4V1) and 2477 kg/ha (D1V2) while simulated values ranged from 1057 kg/ha (D4V1) and 2234 kg/ha (D1V2).
