The application of nitrogen levels on pearl millet genotype produced significantly higher green forage yield of 447.82 q ha-1 and crude protein yield of 6.60 q ha-1 in BAIF Bajra. Whereas, the genotype Gaint bajra recorded the highest dry matter yield of 75.88 q ha-1 and Raj bajra chari-2 with the highest crude protein content of 9.33 per cent. The application of 100kg N ha-1 noticed significantly higher green forage yield of 400.32 q ha-1, dry matter yield 75.34 q ha-1 and crude protein yield of 6.98 q ha-1. The application of 100 kg N ha-1 recorded significantly higher and toxic level of nitrate-N in case of BAIF bajra, JHPM-05-1 and NDFB-02 than all other genotypes. The genotype Giant bajra recorded non-toxic level of nitrate-N on application of 100 kg N ha-1 with the highest dry matter yield and green forage yield of 447.72 q ha-1 which is at par with BAIF bajra.
Key words: Forage pearl millet, nitrogen levels, nitrate nitrogen, yield, quality.
