Abstract:
A study was conducted during rabi season of 2019-20 on sandy loam soil to effect of different bio-fertilizers and fertility level on growth, quality and yield attributes of cowpea. As treatments used combination of RDF, bio-fertilizer and organic manure. Results indicated that application of 75% RDF with organic manure (FYM and VC @2t/ha) and combination of bio-fertilizers (Rhizobium, PSB, Azotobacter and Azospirillum @ 2kg/ha) significantly increases the parameters viz. plant height, percent emergence, no. of leaves, no. of branches, root length, number of pods/plant, number of seeds/pod, pod length, chlorophyll content and protein content, among all the treatments the application of Rhizobium+ FYM + Azotobacter + Azospirillum + PSB +75% RDF was found most effective as showed significant difference under different levels of fertility and bio-fertilizers application. The next effective treatment was Rhizobium+ Vermicompost + Azotobacter + Azospirillum + PSB +75% RDF, Rhizobium+ Vermicompost + FYM +75% RDF, Rhizobium + Azospirillum + PSB + 75% RDF. The other treatments of Rhizobium + Vermicompost + 75% RDF, Rhizobium + FYM + 75% RDF and Rhizobium + 75% RDF were intermittent, however, much better than the un-inoculated control. These treatments though were at par with each other in most of the parameters like percent emergence, number of leaves, number of branches, number of pods/plant, number of seeds/pod, pod length, chlorophyll content and protein content etc.
