Abstract: Faba bean (Vicia faba L.) is a multi-purpose crop owing to its immense economic and ecological benefits. Genetic variability assessment for agronomic traits is a crucial step in improving the yield and yield components of the crop. Phosphorus deficiency seriously affects the yield of faba bean. The present study was conducted to evaluate the genotypic variability of faba bean for agronomic traits. Twenty and 12 genotypes, in the field and greenhouse respectively, were planted under two P fertilizer regimes (0 and 46kg/ha). Analysis of variance indicated highly significant (P<0.01) genotypic variation for most of the agronomic traits under both field and greenhouse; while grain yield (GY), days to fifty percent flowering (DFF), number of pods per plant (NPP) and days to 90% maturity (DNM) had significant genotype by location interaction. The agronomic performance of P-unfertilized (P-) treatments was significantly reduced; with the effect ranging from -4.6% for DNM to 20.3% for NPP in the field; and from -3.6% for DFF to 21.6% for shoot dry weight per plant (SDWP) in the greenhouse. Correlation analysis indicated that most traits were strongly correlated to one another; with consistently significant correlation among GY, DFF, and NPP. Biomass production per day (BPD), GY, SDWP, DNM, and NPP were the highest contributors to the genetic variation. Mean comparisons and biplot analysis results revealed that genotypes Moti, Gebelcho, Dosha, Tumsa, and Didea had superior agronomic performance under all conditions. The study revealed the availability of genotypic variation among the faba bean genotypes for agronomic traits.

Abstract: Lentil is one of the most important food legumes consumed widely throughout the world. It has a significant untapped potential to meet, at least partially, nutritional, soil fertility, and income requirements of smallholder farmers of Ethiopia. However, lentil production faces numerous constraints such as lack of improved seed in the country. Hence, development and dissemination of improved lentil varieties with its packages is an important task to overcome this problem. This activity was undertaken with the main objective of demonstrating and evaluating recently released Lentil technology under farmers’ management condition in Goro district of Bale Zone and Gindhir district of East Bale zone. Two kebeles from each district and two farmers from each kebele were selected. An improved variety Debine was demonstrated and compared with Asano (standard check) on farmers’ field. The demonstration was laid out on single plot of 10m x 10m areas for each variety by applying the recommended full packages. Yield data on plot base was recorded and analyzed using descriptive statistics while farmers’ preference to the varietal attributes was identified and ranked using pairwise ranking and simple ranking methods. Mini-field day was organized in each kebele to facilitate the way in which experts and farmers can participate in varietal evaluation and selection based on their selection criteria. The average yield of Debine (1743kg/ha) is higher than Asano (1400kg/ha). Furthermore, farmers selected Debine due to its higher number of branch/plant, higher number of pod/branch, high yielder, better adaptable to environment, better drought tolerant, better plant height, and better tolerant to frost. Thus, Debine is recommended for wider scaling up/out activity in the districts.
