F ield pea (Pisum sativum L.) is a self-pollinated diploid (2n=14) annual cool-sseason pulse crop. It is also a major food legume with a valuable and cheap source of protein having essential amino ac-ids that have high nutritional value for resource-poor households (Nawab, 2008;Getachew, 2019). It is widely grown in the cooler temperate zones and in the highlands of tropical regions of the world. The crop is cultivated in a wide range of soil types from light sandy loam to heavy clays but does not toler-Abstract | Field pea (Pisum sativum L.) is one of the leguminous crops that is rich in protein and essential amino acids. A field experiment was conducted during the 2019 cropping season consisting of eight (Bursa, Burkitu, Adi, Herena, Hortu, Letu, T/shaman, and Weyib) improved field pea varietiesand one local variety at west Showa zone Oromia region to identify high yielding varieties. The experiment was carried out using a randomized complete block design with two replications at Babich, Goda Hora, Chelia Rafiso Alenga, EjersaLafo, and Goromti locations. Data on yield and yield-related traits such as harvest index, above-ground biomass, number of seed per pods, and hundred seed weights were recorded. Analysis of variance combined over five locations manifested significant differences among varieties, environment, environment, and varieties interaction for grain yield and other yield-related traits. The combined mean of grain yield of varieties indicated that Bursa (3.03 t/ha), Adi (2.84t/ha) and Weyib (2.83 t/ha) varieties had the highest grain yield advantage over the other tested varieties without significant difference among the order, whereas Burkitu (2.3 t/ha), Herena (2.35 t/ha) and Hortu (2.39 t/ha) varieties manifested low grain yield. Generally, it is better if the work is repeated in the future for more justification since it was only one season experiment and the grain yield stability test of the higher yield varieties is advisable before recommending the varieties for largescale production at the studied area.

Food insecurity throughout Sub-Saharan African countries is a common problem and needs a sustainable solution to improve crop yield production, rather than agricultural area expansion. Vegetables are important in sustaining the livelihood of many small-scale and subsistence farmers throughout Sub-Saharan African and contain vitamins, minerals, and essential amino acids, none has cholesterol and most are low in fat and calories. Vegetables also high in fiber, which helps keep the digestive system healthy. Vegetable production in Sub-Saharan Africa faces numerous agronomic constraints that will have to be overcome to feed the increasing population and to fight malnutrition. Major areas on the continent consequently experience nutrient limitation as a major yield gap component, especially in densely populated areas. Now a day one possible solution may come from insect farming, a growing industry with broad potential. Black soldier fly (Hermetia illucens L) feces (frass) may have great potential as a valuable organic bio-fertilizer by positively affecting soil fertility and ultimately vegetable yields. However, the understanding of this positive effect of frass is still limited in our community and very few researchers are trying to determine the effects of this bio-fertilizer on vegetable growth and soil fertility amendment and to explore the utilization of this waste product as a novel organic bio-fertilizer. As nitrogen and phosphorus uptake observed in plots treated with black soldier fly frass fertilizer compared to plots treated with the commercial organic and mineral fertilizers could be attributed to better supply and availability of nutrients from the newly introduced frass fertilize. Clearly black soldier fly frass fertilizer performed better than commercial and inorganic fertilizer. Therefore, further study and awareness creation should be conducted to promote the feasibility of black soldier fly frass bio-fertilizer application in vegetable production and its role in soil fertility amendment.
