Seed traits related to plant stand establishment were studied in chickpea during Rabi, 1997 at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru, Hyderabad and on two farmers fields located at Yelimella village, Rangareddy Dist., A.P. Ten plots (lm x Im) were selected randomly in both the farmers fields. In farmer-1 field half of the plots were irrigated and no irrigation was applied in farmer2 field because it rained seven days after sowing. Soil moisture was determined at the time of sowing and after irrigationirainfall in order to relate differences in plant stands with soil moisture content in the seed bed.At ICRISAT center, four genotypes, which differed in seed size, were studied. Two were local cultivars, collected from the two farmers (farmer 1, farmer 2) ard the other two varieties (Annigeri, ICCV2) were taken from ICRISAT. Crop was sown on three different dates to create differences in soil moisture at the time of sowing. In farmers' fields plant stands were very poor ranging from 4-17 plantslm2. Reasons for poor plant stand in farmer-1 field was suboptimum seed rate, where as in farmer-2 field, it was inadequate soil moisture and poor seed soil contact due to broad cast method of sowing. Yields were also low in the experiments on both the farmers' fields. At ICRISAT center, perfect plant stands were established when soil moisture was adequate as observed in sow-l and sow-ll (20% to 28% ). However, the plant stand was reduced drastically when the soil moisture was suboptimum (18.19%) in the seed bed, as observed in sow-Ill . Genotypic differences in plant stand and seed yield were not significant in the field experiments conducted at ICRISAT center...
