SUMMARY

Application of recommended dose of N and P increased the fodder yield of sorghum from 41.11 to 108.54 q ha-1 significantly over absolute control and all other treatments. A decrease in RD of N and P at the tune of 25 % , 50 % and 75 % decreased the fodder yield significantly from 108.54 to 87.64., from108.54 to 75.70. and from 108.54 to 66.32 respectively. Substitution of 100 % recommended dose of nitrogen through FYM increased the fodder yield of sorghum from 41.11 to 56.97q ha-1 over absolute control. Application of recommended dose of N and P also increased the uptake of N, P and K by sorghum significantly from 62.25 to 148.70, 7.40 to 19.53 and 53.44 to 151.96 q ha-1, respectively over absolute control and all other treatments. Decrease in RDF N and P significantly decreased the uptake of N, P and K by sorghum. Application of 100 % recommended dose of nitrogen through FYM also increased the uptake of N, P and K by sorghum significantly from 62.25 to77.48, 7.40 to 10.82 and 53.44 to 85.46 q ha-1, respectively over absolute control.

Key words : Sorghum, fodder yield, Nitrogen, Phosphorus and potassium, uptake
