abstract: Soil solarization greatly reduced the native
chickpea Rhirbbium population. 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.
