Growth and Yield Response of Rice Bean (Vigna umbellata) Fodder to Different Levels of N and P

Study to determine the effect of different levels of N and P on the fodder yield and quality of rice bean comprised NP combinations of 0-0 (control), 25-25, 25-50, 25-75, 50-25, 50-50 and 50-75 kg ha-1. Plant height, number of branches, leaves and leaf area increased significantly by the application of N and P over control. Maximum green fodder yields of 50.35, 51.61 and 53.03 t ha-1 were obtained in plots fertilized @ 50-25, 50-50 and 50-75 kg ha-1, NP respectively. Crude protein, crude fibre and ash contents of the rice bean were increased by increasing rates of N and P.
