Description Usin a plant Infection d l l u t l o n method developed at ICRISAT
for count ? ng chickpea rhlzobia the population of chickpea Rhizobiun
has been studied i n Alfisols, Vertisols and Entisols. Sane of the
soil samples collected from traditional chickpea growing areas
have been found to have low populations of this specific Rhi obium
Rhlzobium numbers de8c e ased wi th depth i n a Vertisol from + ;
s o i l at [T-IS an to 1 per g s o i l at 90-120 cm. A 100-fold
decrease in populat Ion was recorded when wet- 1 and paddy f 01 1 wed
chickpea. Of flve ICRISAT mandate crops (sorghum, millet, groundnut,
chickpea and plgeonpea) i n pot culture, chickpea roots are
most stitnulatory t o the ~~ultlplicatioonf chickpea rhlzobia.
