The productivity of arid legumes in arid and semi-arid tracks remains
virtually stagnant over decades because of their susceptibility to root
diseases. The information on interaction of beneficial nitrogen fixing
rhizobia with particular reference to arid legumes of the region is limited.
Systematic studies on predominant species Sinorhizobium saheli in
management of root pathogens in arid legumes were undertaken. In-vitro
interactions of root pathogens and S. saheli isolated from arid legumes
significantly suppressed the growth of all fungal pathogens in presence
of S. saheli. In addition the growth of Rhizobium was stimulated in
presence of different root pathogens. A field experiment on integrated
disease managementexhibited that the maximum root nodulation with
the maximum seed yield of 1325 kg/ha was observed from treatment
where seeds were treated with S. saheli. Whereas, the minimum root
nodulation was recorded in treatment, where a mixture of isolated fungal
root pathogens were co-inoculated with S. Saheli was recorded from
cowpea. The minimum seed yield was recorded from treatment wherein
the mixture of isolated root pathogens of arid legumes was co-inoculated
with S. Saheli due to increased disease pressure. The results of in-vitro
and in-vivo efficacy of S. saheli strains suggest that their co-inoculation
with PGPR’s can not only reduce the use of chemical fertilizers but also
can significantly enhance yields by increasing plant growth and
suppressing soil borne plant pathogenic fungi.
