The men In vitro digestibility of BN 2 grass increased significantly over control from 42.21 to 47.01 per cent with N application at 150 kg N/ha. The increases were in the order of 5, 3, 8,8 and 11.4 per cent over control. 50,100 and 150 kg N/ha respectively applied after each cut. Application of ZnSO, at 5.0 kg/ha/ cut increased the digestibility over control from 44.47 to 45.74 per cent, The highest yield of digestible dry matter (35.50 t/ha) was obtained with 150 kg N/ha. Application of N at 50,100 and 150 kg/ha increased the yield by 82.7, 51.6 and 55.5 per cent over control respectively. The physical optimum dose of N worked for this parameter was 139.2 kg N/ha/cut. Application of ZnSO, et 5.0 kg/na increased the yield by 13.4 per cent over control. The study indicated the benefical role of N and Zn in improving the feed value of the fodder obtained.
