Description A field study was conducted for 2 years during 1992-93 to find out the genotypic response in terms of yield and itsattributes and to assess the suitability of varieties under varying planting dates. The experiment comprised of 5 plantingdates and 12 predominant soybean (Glycine max (L.) Merr.) varieties. Significant differences were obtained for yield andmost of the yield attributes among planting dates and among varieties. Early planting by 20 June was found to be the mostappropriate for high seed yield (I 666 kg/ha) across years and varieties. In subsequent plantings of 30 June; 10,20 and30 July, there were yield reduction of 4.8,8.5,28.1 and 39.7% respectively. Suitable soybean varieties, viz 'JS 335', 'NRC 2'and 'JS 71-05' were identified to give high soybean yield across all planting dates and years. The reduction in seed yielddue to late plantings was mainly due to the combined effect of reduced total biomas, pods/plants, plant height, number ofbranches, 100 seed weight, days to flowering and days to maturity.
