A field experiments was carried out at Zonal Agricultural Research Station, Vishweswaraiah Canal Farm, Mandya, University of Agricultural Sciences, Bangalore, Karnataka, under All India Coordinated Research Project on Forage Crops during kharif season of 2017 to study the response of pearl millet genotypes to nitrogen levels. The research results revealed that national check Giant Bajra recorded significantly higher green forage, dry matter, crude protein yield and total digestible crude protein yield (326.5 q, 75.4 q, 5.8 q and 4.9 q/ha, respectively). Application of nitrogen 90 kg/ha significantly recorded higher green forage, dry matter, crude protein yield and total digestible crude protein yield (367.7 q, 92.9 q, 6.1 q and 5.2 q/ha, respectively). The Agronomic efficiency of nitrogen was higher (192 kg green fodder kg-1 of Nitrogen) with application of nitrogen 30 kg/ha. The net monetary returns (Rs 16,652/ha) and B : C ratio was higher (1.83) with application of nitrogen 90 kg/ha.
Key words:Pearl millet, green forage yield, dry matter yield, nitrogen use efficiency phenology, regeneration, sowing date
