| An experiment was conducted to evaluate the effect of various levels of nitrogen and phosphorus fertilizer on the yield and nutritional value of Jumbo grass (Sorghum Grass × Sudan Grass). The experiment was conducted by using five different levels of nitrogen (N) fertilizer viz. 0(N 0 ), 40(N 1 ), 80(N 2 ), 120(N 3 ) and 160(N 5 ) kg N/ha in the form of urea and three levels of phosphorus (P) fertilizer viz. 0(P 0 ), 10(P 1 ) and 20(P 2 ) kg P/ha in the form of Triple Super Phosphate (TSP).

... e treatments were randomly assigned to each of three blocks in 5×3 factorial experiments in randomized complete block design (RCBD). A significant effect (P<0.01) was found on green biomass yield at 80 (N 2 ) and in case of P application for green biomass yield, statistically non-significant (P>0.05). Application of N fertilizer had a significant (P<0.01) effect on DM yield at the dose N 1 (40 kg/ha). DM content (g/100 g DM) decreased significantly (P<0.01) with increasing level of N fertilizer. P fertilizer had no significant effect on DM content. CP content increased significantly (P<0.01) with the increasing level of N fertilizer up to 80 kg N/ha and linearly decreased with increasing level of P fertilizer. N fertilizer application had a significant (P<0.01) effect on OM yield at N 1 (40 kg/ha) but further increase N application did not show any significant result of OM yield. A significant effect (P<0.01) was found on EE content up to N 2 (80 kg/ha) but ash content decreased significantly (P<0.01) with the increasing level of N fertilizer and P fertilizer had non-significant effect on EE and ash content. ADF content decreased with the increasing rate of N fertilizer. There was no significant effect (P>0.05) on NDF content of Jumbo grass. P content of Jumbo grass showed significant effect (P<0.05) by increasing levels of P. IVOMD content increased non significantly (P>0.05), where ME content increased significantly (P<0.01) as the level of N fertilizer application . P fertilizer application had no significant effect (P>0.05) both on IVOMD and ME. Based on the above findings, it may be suggested that Jumbo grass can be cultivated through the application of 80 kg N/ha and 10 kg P/ ha for maximum production.
