Effect of Irrigation and Foliar Nutrition on Yield and Economics of Rice Fallow Blackgram

The present investigation, entitled “Effect of Irrigation and Foliar Nutrition on Yield and Economics of rice fallow blackgram” was carried out at the Agricultural College Farm, Naira, during the rabi season of 2023-24. The experiment was laid out in Strip-plot design with 3 main plots viz., M1- No Irrigation; M2-Irrigation at flower initiation and M3-Two irrigations one at flower initiation one at early pod development and 4 Sub Plots viz., S1- water spray; S2- 1%19:19:19(NPK); S3-2% Urea; S4-2% DAP; S5-4 ml Nano urea; S6-3ml Nano DAP with two replications for each treatment. The results showed that irrigation at flower initiation and early pod development stage and foliar spray of 2% DAP at flower initiation and early pod development stage recorded maximum seed yield, haulm yield and economics.
