Abstract:
A field experiment was conducted during the rabi season of 2019-20 at Integrated Farming Systems Research Farm, JAU, Junagadh. The soil was medium black calcareous in texture, rich in organic carbon, medium in available N, P₂O₅ and K₂O with alkaline in reaction (pH of 8.27). Total twelve treatment combinations, consisting of three fertilizer levels (Control, 75% RDF and 100% RDF) and four bio-fertilizer inoculations (Absolute control, Rhizobium @ 600 g ha^-1, PSB @ 600 g ha^-1, Rhizobium + PSB @ 600 g ha^-1 each) were allotted randomly to different plots and tested in a randomized block design (Factorial) with three replications. The results indicated that application of 100% RDF recorded significantly higher values of yield attributes, yield, harvest index, Rhizobium count, PSB count and total microbial count and also higher gross and net realization along with higher B: C ratio. Yield attributes, yield, harvest index, Rhizobium count, PSB count and total microbial count and also higher gross and net realization along with higher B: C ratio was recorded significantly higher with the dual inoculation of seed with Rhizobium and PSB @ 600 g ha^-1 each. Thus, higher seed, straw and biological yields as well as net returns in fenugreek can be realized with application of 100% RDF (20 kg N + 40 kg P₂O₅ ha^-1) along with dual inoculation of seed with Rhizobium and PSB @ 600 g ha^-1 each.
