Ten Soybean [Glycine max (L.) Merr.] genotypes were evaluated for physico-chemical characteristics. Physical pod characters viz. 100 pod weight, 100 pod volume, apparent density, bulk density and projected area (1-seeded, 2-seeded and 3-seeded) were observed in range of 26.10-73.00 gm, 90-250 ml, 0.245- 0.539g/cm3, 0.047-0.195 g/cm3 and 1-6 cm2 respectively for soybean genotypes in June, September and November. Physical seed characters viz., 100 seed weight, 100 seed volume, seed density and seed texture were observed in range 7.40-27.83 gm, 7.00-28.00 ml, 0.71-1.16 g/cm3 and 1.69-8.26 kg/grain respectively in June, September and November. Proximate composition viz. Crude protein, crude fibre, ash content, crude fat, moisture content and total carbohydrate were observed in the range of 6.77-16.02, 2.02-4.42, 1.42-5.09, 2.60-9.82, 42.37-69.50 and 10.91- 27.82% respectively in June, September and November. Limiting amino acid viz. methionine and tryptophan were observed in range of 0.16-1.55% and 0.52-2.62% for soybean genotypes in June, September and November. Significant differences were observed amongst cultivars as well as among date of sowings for various quality characters.
