Effect of Different Levels of Fertilizers on Productivity and Nutrient Dynamics of Browntop Millet

Abstract

A field experiment was conducted at Agricultural Research Station, Baljigapade, Chikkaballapur taluk and district, which comes under the Eastern Dry Zone of Karnataka during Kharif season 2018. 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 P2O5 (20 and 30 kg ha-1) and three levels of K2O (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 P2O5+30 kg K2O ha-1 with Farm Yard Manure (FYM) increased the micronutrient availability in soil N (150.29 kg ha-1), P2O5 (17.60 kg ha-1), K2O (160.84 kg ha-1). Application of FYM @ 6.25 t ha-1+30 kg N+20 kg P2O5 +20 kg K2O 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 T10 and 59.07 percent in T9 as compared to the absolute control.
