Abstract: 'I'hough groundnut is nodulated by a number of rhizobia \nbelonging to the cowpea miscellany, the nodulation and nitrogen \n(Nz) I'ixulion acliicvcd unclcr I'itrmcrs' conditions is ol'tcn \ninadequate. Studies at IC'K ISA I have attempted to overcome this \nby examining a large number of inoculant strains and various \nmethods of' inoculation. \nLarge variability between groundnut rhizobia in ability to fix N2 \nexists, but poor correlations between nodule mass and plant dry \nweight gains can occur. lnoculum size is important with nodule \nnumber and distribution and N2 fixation enhanced by heavier \ninoculation rates. Liquid inoculants have provided greater \nincreases in yield than either granular or seed slurry inoculation, \nthe latter method reducing germination and stand establishment. \nSeveral field trials at ICKISA'I', both in the rainy and irrigated, \npost-rainy seasons, have given significant responses to inoculation, \neven though the soil already contains lo4 rhizobialg. lhe cultivar \nRohut 33-1 with strain NC 92 has eiven most consistent results.
