ABSTRACT
The field experiment was conducted in Agroforestry block, UAS, GKVK, Bangalore during rabi 2015-16 to know the influence of Bio NPK on growth and yield of maize. The soil of the experimental site was red sandy loam soil with a medium status of nitrogen, phosphorus and potash (314, 38.91 & 178.54 kg ha-1). The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications and there were seven treatments consisting of application of Bio-NPK@100 kg acre-1 (T1), application of Bio-NPK @ 50 kg acre-1+ 100 % recommended dose of fertilizer (T2), application of Bio-NPK @ 100 kg acre-1+ 100 % Recommended dose of fertilizer (T3), application of Bio NPK@ 50 kg acre-1 + 75 % recommended dose of fertilizer (T4), application of Bio-NPK @ 100 kg acre-1 + 75 % recommended dose of fertilizer (T5), application of 100 % recommended dose of fertilizer @ T6, Absolute control (T7). Significantly higher grain yield was noticed in application of Bio-NPK @ 100 kgacre-1 + 100 % recommended dose of fertilizer (10763 kg acre-1), which was on par with the application of Bio-NPK @ 50 kg acre-1 + 100 % recommended dose of fertilizer (10382 kg acre-1) compared to absolute control (5408 kg acre-1).
Key words :
B:C ratio, Bio-NPK, Growth & yield attributes, Maize.
