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.

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.

The Impact

The dramatic reduction in the diversity of crops in the last century is often attributed to the consolidation of scientific breeding, probably because the two processes have occurred at the same time. We carried out a breeding program to enhance the Castellfollit del Boix landrace of common bean (Phaseolus vulgaris L.) in a low-input environment to determine the effects of breeding on a landrace at risk of disappearing. The program increased the number of accessions conserved ex situ and obtained more efficient genotypes that are less likely to be abandoned by farmer without altering the characteristics that consumers appreciate most. As a result, the availability of the product, its promotion, and its use have increased. We propose a Conservation Potential Index to measure the impact of changes in the crop’s epiphenotype, and also apply it to a set of landraces from several crops. We argue that scientific breeding and information gathered in the context of genetic improvement programs can help to conserve biodiversity when they aim to adapt materials to different local environments, rather than having a negative impact on the biodiversity of crops. This approach contrasts with the genetic erosion that results from efforts to homogenize environments by increasing inputs, so that a few improved varieties adapted to these environments can be grown.

Selection Of

Advanced genotypes of common bean (Phaseolus vulgaris L.) were tested on-station and on-farm to evaluate their performance and acceptability under farmers' circumstances. Farmers were given seed of the genotypes to plant a minimum area of 100 m2 to be grown as a sole crop or intercropped with sorghum according to their preference. Yield, seed colour, taste, maturity time, disease reaction, growth habit and many other bean characteristics were assessed by farmers. The promising genotypes were higher yielding than the farmers' genotypes in most testing sites. Pairwise ranking of the genotypes showed that in export-oriented western Hararghe, white pea bean (navy bean) type Awash-1 and food bean G-2816 were preferred. In eastern Hararghe GLP ×92 and G-2816 were highly preferred but white pea beans were not preferred. Genotypes in advanced observation nurseries were also evaluated by the farmers and some of the genotypes have been promoted for further testing in yield trials. Selection criteria have been proposed by the farmers in each region. Future breeding and selection of genotypes will incorporate the proposed selection criteria and priorities of the two regions.

Abstract Background Agriculture remains to be the leading sector that contributes enormously to economic development in Ethiopia. Despite its significant contribution to livelihoods, the sector faces persistent challenges due to depletion of natural resources and soil erosion that resulted in diminishing crop and livestock productivity. In order to curb the effects of land degradation, the Government of Ethiopia has been taking serious measures to expand Soil and Water Conservation (SWC) practices throughout the country. Despite the efforts made, the adoption of new practices by farmers have been generally low. This study was aimed to assess factors influencing smallholder farmers’ decision on the use of improved structural SWC practices in Haramaya district, eastern Ethiopia. A multi-stage sampling technique was used to select 120 farm households and 248 plots. A structured interview schedule was used to collect primary data. Descriptive and inferential statistics and Multinomial Logit (MNL) regression model were used to analyze the data. Results The key findings showed that a host of socio-demographic, economic and institutional factors significantly affected smallholders’ decision to adopt improved structural SWC. In this study, we found that education, farming experience, plot area, distance of the plot from dwelling, number of economically active household members, and extension contact were the significant predictors of using improved SWC structures. Conclusions Based on our findings, we conclude that improved SWC measures should be scaled up through a concerted effort of extension workers, local administration and other relevant non-state actors. In particular, the extension system should encourage rural communities on sustainable management and use of natural resources. Moreover, the need to create learning opportunities through facilitating appropriate training programs for farmers and focusing on proper management of available economically active household members should be emphasized.
