Abstract:

A field experiment conducted during five consecutive rabi seasons (2016-17 to 2020-21) at research farm of R.K. (P.G.) College, Shamli (U.P.), with three replications under split-split plot design. FYM levels (0, 5, 10 t FYM/ ha) were taken as main plot, three N levels (40, 80, 120 kg N/ ha) as sub plot and four biofertilizer treatments (Control, Azotobactor, Azospirillum, Azotobactor + Azospirillum) as sub-sub plot. 10 t FYM/ ha resulted decrease in bulk density from 1.23 Mg/M3 to 1.18 Mg/M3. Highest WHC (0.35 Kg/Kg soil), organic carbon (0.91%), CEC {10.59 Cmol (P+)/ Kg soil} and available N (225.3 Kg N/ ha) noticed with 10 t FYM/ ha. The plots receiving 10 t FYM/ ha maintained 24.78, 24.76, 54.61 and 67.56 percent higher effective tillers, grain yield per spike, biological and grain yield/ ha, respectively. The plants with 120 kg N/ ha, produced 31.83 % higher biomass and 31.46 % higher grain yield over 40 kg N/ ha. Highest protein content (13.25%) and protein yield (785.72 kg protein/ ha) was registered with 10 t/ ha FYM. Inoculation with Azotobactor + Azospirillum had 7.06 % higher protein in their grains over uninoculated control. Application of 10 ton FYM/ ha resulted 46.35 and 24.56 % higher net return over 0 ton and 5 ton FYM/ ha, respectively. Highest gross return (` 112091/ ha), net return (` 76343/ ha), output: input (3.14) and benefit: cost ratio (2.14) was analyzed with 120 kg N/ ha. Azotobactor + Azospirillum resulted, 34.85% higher net return over no inoculation.
