Abstract:
The field experiment was conducted to optimise seed rate through seed rate compensation on growth, seed yield and quality in JS335 and JS9560 soybean varieties during 2017-18 at NSP, University of Agricultural Sciences, Bengaluru. The experimental material for the study comprised of 2 soybean varieties (JS335 and JS9560) procured from NSP. The results revealed that, among the seed rate compensation levels, C₁ recorded higher number of seeds per pod (3.68), number of pods per plant (44.25), seed yield per plant (9.60), seed yield per plot (1.90); germination (96.83%), seedling length (34.54) and seedling dry weight (8.67mg). Among the varieties, V₁ (JS 335) recorded higher number of seeds per pod (2.67), Number of pods per plant (70.52), seed yield per plant (8.95), seed yield per plot (1.51); germination (96.33%), seedling length (31.91) and seedling dry weight (48.23mg). The lowest yield and quality parameter was observed in C₅ (Aged seeds of 50 per cent germination with compensated seed rate, 87.5 kg/ha).
