Abstract
Soybean (Glycine max L.) is the leading oil seed crop of the world in term of both area and production. It contributes about 50 per cent of the edible oil production. A pot experiment was conducted during Kharif season at UUHF to study the effect of organic manures on growth , flowering , enzyme activity and yield of Soybean ( Glycine max L.) in relation to climate change under mid hill condition of Uttarakhand . The experiment was laid out in RBD with three replications. The Vermicompost, B.D and FYM were applied as a basal dose at the time of sowing. Application of Vermicompost, FYM, BD with rhizobium recorded significantly higher plant height (82.40 cm), number of leaves per plant (51.50) and leaf area (391.50 cm2), dry matter accumulation (22.43 g/plant) and physiological parameters NAR, CGR, RGR, number of pods per plant, number of seeds per pod, test weight, biological yield (55.7 g/plant), grain yield (27.5 g/plant), harvest index in T4Vermicompost 10t/ha + BD 1t/ha + with rhizobium and lower in T11 (FYM – 7.5t/ha + BD 2.5t/ha + Without rhizobium).. Organic manures with rhizobium had great influence on Nitrate Reductase activity and Protein content. Significantly higher growth and biochemical parameters were recorded in T4 and lowest in T11.Where as the results revealed that the basal application of organic manures found to be beneficial in increasing seed yield and yield contributing characters. Meteorological parameters showed a positive effect on growth and yield of Soybean. There was a positive and significant correlation between seed yield and all growth and biochemical parameters.
