A field experiment was conducted on heavy black soil of College Farm of N. M. College of Agriculture, Navsari Agricultural University, Navsari (Gujarat) during the rabi season 2016-17. The experiment comprising twelve (12) treatment combinations were laid out in factorial randomized block design with factorial concept and replicated three times. The treatment consisted combinations of three levels of nitrogen viz.,20 kg N/ha (N1), 40 kg N/ha (N2), 60 kg N/ha (N3), two levels of organic manures i.e. FYM @ 5 t/ha (M1) and bio-compost @ 5.0 t/ha (M2) and two levels of bio-fertilizer viz., No seed inoculation (B1) and seed inoculation with azotobactor (10 ml/kg of seed) (B2). Experimental results indicated that significantly highest grain yield (1225 kg/ha) and stover yield (2766 kg/ha) recorded by nitrogen application @ 60 kg N/ha (N3). Fertilization with 60 kg N/ha recorded significantly highest protein content (15.37 %) and protein yield (188.36 kg/ha). In case of economic same level of nitrogen recorded significantly highest net returns of ₹ 43916/ha and B: C ratio of 2.54. In case of organic manure maximum grain and stover yields of 1040 and 2440 kg/ha, respectively were also recorded with the application of bio-compost @ 5.0 t/ha (M2). Application of organic manures fails to exert its significant effect on protein content and protein yield. The highest net returns of ₹ 38482/ha with B:C ratio of 2.57 were obtained with an application of bio-compost @ 5.0 t/ha (M2). In case of bio-fertilizer, grain yield (1059 kg/ha) and stover yield (2487 kg/ha) were recorded significantly highest with azotobacter seed inoculation. Significantly highest protein content (14.37 %), protein yield (154.26 kg/ha) were recorded under seed inoculation with azotobacter (B2). Significantly highest net income of ₹ 34144/ha with BCR value of 2.22 was obtained with the application of azotobacter (B2).

Key words: Azotobacter, Bio-compost, Economic, FYM, Grain amaranth, Protein, Yield.
