Abstract:
Field experiment was carried out at the Instructional Farm of the University
of Agricultural Sciences, Bangalore to study the response of cowpea to seed
inoculation with selected Rhizobium strains. Significant increase in yield, plant
top dry weight and leghaemoglobin content of nodules were noticed in plants
inoculated with the strains 8 and 12, Correlation studies showed significant
correlation between leghaemoglobin content of nodules, plant top dry weight and
final grain yield. No significant correlation was observed between nodule number
and nitrogen content of plant top on Thirtieth day of growth and final grain
yield.
