Effect of integrated nutrient management on yield components, yield and Nutrient uptake of green gram

Field investigations was carried out at the experimental farm, Department of Agronomy, Annamalai University, Annamalai Nagar to study the effect of integrated nutrient management in greengram (Vignaradiata L). During 2014 (February to April) experiment was laid out in randomized block design with three replications. There were altogether eight treatments viz., T1-control, T2-RDF@ 25kgN, 50 kg P2O5, 25 kg K2O and 10 kg S ha-1, T3-RDF+FYM 5t ha-1, T4-RDF+Vermicompost 3t ha-1, T5-RDF+composted sugarcane trash5t ha-1,T6-RDF+FYM5t ha-1+Rhizobium +Phosphobacteria, T7-RDF+vermicompost 3t ha-1 + Rhizobium +Phosphobacteria and T8- RDF+composted sugarcane trash 5t ha-1+Rhizobium +Phosphobacteria. The combined application of organic and inorganic fertilizers significantly influenced the growth and yield components of greengram. Among the treatments, soil application of RDF+vermicompost 3t ha-1 + Rhizobium +Phosphobacteria (T7) had favourably increased the yield components such pods per plant, number of seeds per pod and test weight and seed yield (1280 kgha-1). The same treatment also recorded the highest uptake of NPK during the cropping period. The control T1 recorded the lowest seed yield of 450 kgha-1.
