“…However, a signifcantly minimum number of emerging parasites was recorded from resistance genotype "Ashange" (Table3). Tis genotype showed a good adaptation under Orobanche-prone areas [7] and demonstrated as good level of resistance to O. crenata [15] in Ethiopia.…”

Orobanche crenata is a serious parasitic weed and a major constraint on legume crops, particularly for faba bean, which causes about 75–100% of yield losses in Ethiopia. Twenty faba bean genotypes were evaluated in Orobanche infested fields and pot experiments in Tigray, Ethiopia. The aim of the study was to determine the critical stage of host plants affected by parasite and to evaluate resistance level of faba bean genotypes. The degree of infection and host resistance level was evaluated at three host growing stages (flowering, pod setting, and maturity stages) using different traits like number of Orobanche emerged per plant, per plot, incidence, and severity. The agronomic data such as stand count at emergence, flowering, pod setting, maturity, plant height, pod number, seed per pod, hundred seed weight, and grain yield were recorded from five and three randomly selected plants in the field and pot experiments, respectively. The analysis of variance showed that there were high significant variations p < 0.01 in measured traits between the three host growing stages and between genotypes in agronomic traits. The effect of O. crenata on host plant was started from the flowering stage, but the pod setting stage is economically important stage at which actual effect of the parasite was observed both at field and pot experiments. Based on the result of the study, all tested traits at field and pot experiments allowed separating the faba bean genotypes into three groups: partially resistant and or tolerant genotypes “Ashange, Dide’a, and Obse,” moderately susceptible genotypes “Holleta, Selale, Wayu, Welki, Mesay, Bulga, Degaga, Gachena, Mosise, and Shalo,” and highly susceptible genotypes “Moti, Gebelcho, Dosha, Tumsa, Hachalu, and Tesfa Aloshe.”

“…In Ethiopia, there are two broomrape species (O. crenata and O. ramosa) that attack mainly legume crops and cause the yield losses up to 100% [7]. However, O. crenata is broadly distributed and has a wide host range which causes substantial losses and damage in pulse crops, especially faba bean.…”

Broomrapes (Orobanche spp.) are the serious roots parasitic weed to legumes crop production in many countries. In Ethiopia, Orobanche crenata is a dominant parasite and a major constraint to faba bean (Vicia faba L.) cultivation, especially in the Northern parts of the country. Presently, it reduces crop production and has forced farmers to stop growing faba bean crop. Thus, it is necessary to find new sources of resistance, understand means of resistance mechanisms to facilitate faba bean resistance breeding, and identify the best performed with high yielding variety to sustain their production and productivity. Thus, to evaluate the performance and their degree of resistance, twenty faba bean varieties were tested under the area affected by Orobanche infestation, at Korem experimental site of Alamata Agricultural Research Center, Tigray, Ethiopia during 2017 cropping season by using Randomized Complete Block Design (RCBD). All difference among faba bean varieties was analyzed using Tukey's Standardized Range (P ≤ 5%) Test. Higher level of broomrape infection was observed during host-pod setting stage. During evaluation, 13 out of 20 tested faba bean varieties were the superior yielding varieties (312.5-3129.17 kg ha-1), whereas the remaining seven varieties completely lost yield due to 100% Orobanche infestation. Cluster analysis was then carried out and the varieties were grouped into different clusters with different sizes based on their level of resistance or susceptibility. Three varieties 'Ashenge, Dedia and Obse' were selected for their best performance. Accordingly, Ashenge variety was selected as partially resistant with highest yield provided due to lowest occurrence of Orobanche infestation within variety. Future breeding program therefore, should mainly focus on these three selected varieties to improve the problem of faba bean production by using conventional and molecular breeding methods.

“…It is among the most important grain legume crops grown in Ethiopia for food as a source of protein and for enriching the soils with nitrogen as a rotation crop ameliorating soil fertility. It has a high nutritional value and is used almost daily in the human diet of many Ethiopians [2]. Seeds of leguminous plants are a valuable source of amino acids, especially lysine, in human and animal diets [3].…”

Faba bean (Vicia faba L.) is one of the most important winter legume crops for human consumption as a green or dried, fresh, or canned. Low soil fertility and acidity are the major constraints of faba bean production in Ethiopia. A field experiment was conducted in the Kiremu district of West Oromia, Ethiopia, under rain-fed conditions on a farmer's field to evaluate the effect of different rates of lime and NPSB-blended fertilizer application with and without inoculation on yield components and yield of faba bean. The three factors, lime rates (0, 2, and 4 t ha−1), mineral fertilizer rates (0, 60, 120, and 180 kg·ha−1 NPSB), and rhizobium inoculation (with and without), were combined in 3 x 4 x 2 factorial arrangement of RCBD in three replications. The data were collected on yield and yield components and subjected to the analysis of variance (ANOVA). The ANOVA results revealed that the number of pods per plant, number of seeds per pod, hundred seeds weight, harvest index, aboveground biomass, and grain yield were significantly affected by the treatment. Therefore, the highest faba bean yield was obtained from the application of 2 t limes ha−1, 120 NPSB ha−1, and 500 g·ha−1 rhizobium inoculation, and thus, the integrated application of the aforementioned rates of lime, NPSB, and rhizobium inoculation could be recommended for maximizing the productivity profitability of faba bean production in the study area and similar agro-ecologies.
