Optimisation of rhizobium and arbuscular mycorrhizal fungi benefits for grain legume production in acid soils
Abstract

This study was conducted to evaluate the symbiotic
effectiveness of Rhizobium isolates using soybean and
Phaseolus bean as host plants grown in acid soil (pH 4.5 and
5) from two southern districts of Rwanda. For this purpose, 10
and 33 isolates for soybean and Phaseolus bean respectively
were studied. The two isolates with highest nitrogen fixing
capacity were combined with mycorrhizal species for enhancing
legume nodulation and production in 10 treatments (control with/
without 882mg of TSP/ arbuscular mycorrhizal fungi (AMF),
Rhizobium isolates with/without 882mg of TSP and arbuscular
mycorrhizal fungi in 4 kg). These results indicated that effective
Rhizobium isolates had potential for use as inoculants on soybean
and bean.
