ABSTRACT

A field experiment was conducted during kharif 2008 at Junagadh on effect of bio fertilizer and fertility levels on yield, protein content and nutrient uptake of cowpea. Sixteen treatments comprising of four levels of bio fertilizer viz., without inoculation, with PSB inoculation, liquid PSB inoculation and Rhizobium inoculation and four fertility levels viz., 0, 50, 75 and 100 % RDF were tried in factorial randomized block design with four replications. The result of the experiment indicated that significantly  the highest grain  and stover yield  of 1441  and 1716  kg/ha respectively, was  recorded  in seed inoculation  by  Rhizobium  over  rest of the  treatments. The increased in RDF significantly increased seed and stover yield. Inoculated with Rhizobium significantly increased protein and N, P content   as well as   uptake of N and P by grain and stover. The 100 % RDF recorded the highest protein content as well as content and uptake of N and P by grain and stover but was par with 75 % RDF. Significant improvement in available N and P status in soil was also reported due to Rhizobium inoculation.
