With inoculation, it was possible to increase the population of the Rhizobium in solarized plots. In the 1st year, 47% nodulation was obtained with chickpea inoculant strain 1C 59 when introduced with a cereal crop 2 weeks after the soil solarization and having a native Rhizobium count of <log-' soil, and only 13% when introduced 16 wceks after solarization at the time the chickpeas were sown, with 2.01~d native rhizobia g-' soil. In the non-solarized plots inoculated with 5.61~d native rhiiohia g-' soil, only 6% nodulation was obtained with the inoculant. In the succeeding ycar, non-inoculated chickpea was grown on the same plots without any solarization or Rhizobium inoculation The treatment that showed good establishment of the inoculant strain in ycar I formed 6840 inoculant nodules. Other treatments indicated a further reduction in inoculant success, from 1% - 13% to 1 % - 9%. Soil solarization thus allowed an inoculant strain to successfully displace the high native population in the field and can serve as a research tool to compare strains in the field, irreswive of comwtitive ability.
