Orange-fleshed sweet potato (OFSP) is a bio-fortified crop that is a rich source of beta-carotene (pro-vitamin A) which is necessary for combating the problems related to vitamin A deficiency (VAD). There is an increasing demand by farmers for production and consumption of improved OFSP varieties in the study areas. In order to respond to farmer requests, participatory variety selection trial was conducted with the objective of selecting superior OFSP varieties with farmer’s preferred traits. The trial was conducted during 2019 and 2020 growing seasons across three sites in Gedeb district of Gedeo Zone. Six varieties, including one old OFSP variety as a check were tested in a mother trial using each site as a single replication. For a baby trial, one new and one old variety was given to more than 30 model farmers around each site. Data were collected on agronomic traits such as root yield, above ground biomass, harvest index and sweet potato virus disease from the mother trial and analysis of variance was conducted. The combined analysis showed the presence of significant differences (p≤0.05) among tested genotypes for observed traits. The highest root yield was recorded for Dilla (23.11 t/ha), followed by Alamura (22.57 t/ha), Kabode (18.66 t/ha) and NASPOT-13 which produced the lowest root yield of 12.10 t/ha as compared to the others. Demonstrations of various sweet potato based foods were also made and 18 farmers (13 male and 5 female) were invited for variety assessment and selection based on the recipes. These farmers set sensorial attributes like flavor, taste, texture, and hardness of the cooked roots for taste-tests. Considering overall ranking of the six parameters (taste-tests) and agronomic traits such as root yield, above ground biomass, resistance to virus disease, varieties Dilla, Alamura, and Kabode were selected as the 1st, 2nd and 3rd choices, respectively. Therefore, scaling up of these OFSP varieties should be done in the study area and areas with similar agroecologies in order to alleviate the problems related with VAD.
The experiment was conducted during 2017 at the compound of Hawassa University in the College of Agriculture, Southern Ethiopia during off cropping season. To investigate the performance of different mung bean varieties on response of different growth parameters such as Specific Leaf Area, Leaf area ratio, net assimilation rate, and Relative growth and total dry Biomass.. Three mung bean cultivars were grown in randomized complete block design with three replications. The objective of the study was to assess the performance of mung bean cultivars in relation to growth parameters and to estimate the analysis of growth characteristics using the primary values generated from these cultivars. Data were specific leaf area ratio, leaf area ratio, net assimilation rate, relative growth rate and above ground biomass. There is significant difference among cultivars observed for total dry biomass. The SLA and LAR of all cultivars increment from first sample to second sample as crop development progressed. The highest SLA and LAR were attributed suniana variety. Gofa local cultivar is highest Total dry biomass, since in this study genetic factor and environment are key factors for achieving optimum growth and dry matter production of mung bean cultivars.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
