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.
Cette étude a été menée pour évaluer l’efficacité symbiotique
des isolats de Rhizobium utilisant le soja les haricots Phaseolus
comme des plantes hôtes cultivées dans un sol acide (pH 4,5 et
5) de deux districts du sud du Rwanda. À cette fin, 10 et 33
isolats de soja et de haricot Phaseolus respectivement ont été
étudiés. Les deux isolats avec la plus grande capacité de fixation
de l’azote ont été combinés avec les espèces mycorhiziennes
pour améliorer la nodulation et la production des légumineuses
dans 10 traitements (contrôle avec ou sans 882mg de TSP /
champignons mycorhiziens arbusculaires (AMF), des isolats
Rhizobium avec ou sans 882mg de TSP et champignons
mycorhiziens arbusculaires à 4 kg). Ces résultats indiquent que
les isolats de Rhizobium efficaces ont un potentiel d’utilisation
comme inoculants sur le soja et le haricot.

Notes:
"The 2010 RUFORUM Biennial Conference was the second in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. This record contains an extended abstract accepted under the theme soil science and water management".
