Description Population of "cowpea-group" Rhizobium in fields at ICRISAT
were estimated by the most probable number(MPN) method using
siratro (Macropulium atropurpureum) as host. There was usually a
large variability in Rhizobium numbers between sampling sites in
the same Held. The populations were more consistent in Alfisols
(range from 104 to 3 x 105 /g soil) than in Vertisols (0 to 106 /g soil)
and decreased with depth. In paddy fields, the numbers were very
low. Pigeonpea cultivars ICP-7332 (small seeded) and ICP-1
(medium sized), grown in test tubes, could also be used for the
MPN method. In four of five soils tested, counts with pigeonpea as
host were less than when siratro was used.
