The experimental plot in the field was laid out following a randomized complete block design (RCBD) with fourteen treatments and three replications. The treatments included two levels of N and P 2 O 5 (20 and 30 kg ha -1 ) and three levels of K 2 O (10,20 and 30 kg ha -1 ). Farmyard manure was applied at the rate of 6.25 t ha -1 to all the treatments except absolute control. Results indicated that application of 30 kg N+30 kg P 2 O 5 +30 kg K 2 O ha -1 with Farm Yard Manure (FYM) increased the micronutrient availability in soil N (150.29 kg ha -1 ), P 2 O 5 (17.60 kg ha -1 ), K 2 O (160.84 kg ha -1 ). Application of FYM @ 6.25 t ha -1 +30 kg N+20 kg P 2 O 5 +20 kg K 2 O ha -1 significantly increased growth, yield, macronutrient content and uptake by brown top millet grain and straw against absolute control. The grain yield of browntop millet was increased by 61.46 percent in T 10 and 59.07 percent in T 9 as compared to the absolute control. Original Research Article
