Growth, nodulation and nitrogen (N) fixation efficiency of Banki (Local) and ICGS‐44 (exotic) varieties of groundnut was significantly ( P < 0.05) improved by their inoculation either with NC‐92 or Rudy Patric (R.P.) strains of rhizobium. Nodules did not form without inoculation in plants growing in sterilized sand. Inoculation with R.P. strain of rhizobium resulted in greater shoot growth, N content in shoot and number and weight of nodules in groundnut varieties. The R.P. inoculant increased agronomic efficiency by 112.5 % in Banki and 100 % in ICGS‐44 variety of groundnut. Improvement in N fixation efficiency by inoculation with R.P. inoculant was 334 and 286% in Banki and ICGS‐44 variety, respectively. However, Physiological efficiency was maximum in Banki variety when inoculated with NC‐92 strain of rhizobium.
