Field experiments were conduc(ed in the year 1982 and 1983 to assess the effects of Mn and Mo with Rhizobiumculture on yield and protein content of cowpea variety (C-152) grown on a Typic Ustipsamment soil of Rajasthan. Application of Mn and Mo, either singly or in combination with Rhizobium culture significantly increased the grain yield of cowpea. Protein content of grain and available nitrogen in soil also increased with increasing dose of Mn and Mo with Rhizobium inoculation. The best treatment combination for cowpea was found to be 10 kg Mn and 1 kgMo ha−1 alongwith Rhizobiuminoculation.
