Rhizobial Isolates

This study was committed to examining the symbiotic efficacy difference between wild and mutant rhizobial isolates from lowlands of eastern Ethiopia around Babile, and at the same time to appreciate the enrichment effect of mutagenesis on restraint of common bean (Phaseolus vulgaris L.) nodulating rhizobia to Endmost Salinity and Outmost pH Circumstance. A total of 50 wild rhizobia isolate, and 8 mutant isolates; after mutagenesis were selected based on their ability to endure endmost salt and outmost pH circumstances at laboratory condition. All of the mutants were found to be symbiotically effective. Among the observed rhizobium isolates, wild isolates HUCR (3D, 3A), HUCR 2D, and mutant isolate HUCRM 2D showed the highest symbiotic efficacy. Only the mutant isolates HUCRM2D (tolerated 12% NaCl, and pH4 and pH12), HUCRM5C (tolerated 12% NaCl and pH 4), HUCRM3B (tolerated 12% NaCl) and HUCRM9C (tolerated 11% NaCl) were growing effectively at the point out utmost conditions. Therefore, based on their restraint to utmost conditions and symbiotic efficacy, the above mentioned wild and mutant rhizobia isolates were suggested as nominees for the future development of common bean biofertilizer that grown under endmost saline and outmost pH conditions.

Abstract Common bean (Phaseolus vulgaris L.) is an important source of food and income. However, its on-farm diversity and conservation by smallholder farmers is not known in the east Hararghe Zone of eastern Ethiopia. Thus, field survey was conducted from November 2018 to February 2019 to assess the on-farm diversity, cropping system and the role of gender in production and management of common bean varieties. Common bean producing districts were selected purposively whereas sub-districts (kebeles) were selected randomly. Three kebeles from each of the two major agro-ecological zones, two key informants and twelve general informants from each kebele were selected to constitute a total of 84 informants. The selection of general informants was stratified based on gender and wealth status. Structured interview guide was used to interview general informants whereas semi-structured interview guide was used to interview key informants. Descriptive and inferential statistical analyses were conducted in R (version 3.5.2). Seven farmers’ varieties of common bean were identified of and their diversity was higher in tepid, moist mid highlands (M3) whereas cropped area (ha) was significantly (p < 0.05) higher in tepid sub-humid highlands (SH3) agro-ecology. Most activities of common bean were undertaken by male adults. Insect pests were the prominent constraints of common bean production. Farmers’ varieties were used as food and feed, and soil fertility management. Therefore, their on-farm and ex situ conservation, maintenance of endangered varieties, and shortage of cropping land due to chat plantation need special concern to promote their cultivation.
