Effect of Phosphorus, Sulphur and Biofertilizer on Growth, Yield and Nodulation in Mungbean on Loamy Sand Soils of Kutch
A field experiment was conducted for four consecutive years from 2007-08 to 2010-11 at Centers of Excellence for Research on Organic Farming S. D. Agricultural University, Bhachau, Kutch, to study the effect of P, S and Rhizobium on yield, yield attributes and nodulation of Mungbean. The experiment consisting of three levels of phosphorus (0, 20, 40 kg ha-1), three levels of sulphur (0, 20, 40 kg ha-1) and two levels of Rhizobium (inoculated and uninoculated), total 18 treatment combinations with three replications were comprised in factorial randomized block design. Application of 40 kg P2O5 ha-1 and 40 kg S ha-1 along with Rhizobium inoculation significantly increased the yields, yield attributes and nodulation of Mungbean as compared to control, but it remained at par with 20 kg P2O5 ha-1 and 20 kg S ha-1. Maximum gross realization, net realization along with highest BCR of 6.73:1 was obtained under the treatment of 40 kg P2O5 ha-1 and 40 kg S ha-1 along with Rhizobium inoculation.
