Abstract: Sweet potato is high yield potential and adaptability to a wide range of environmental conditions. However, due to low soil fertility the yield was become low in some part of country. The objective of this study was to evaluate the combined effects of organic farmyard manure and inorganic nitrogen on yield and yield components of sweet potato. Four farmyard manure rates (0, 4.5, 9 and 13.5 ton ha-1) and four nitrogen rates (0, 45, 90 and 135N kg ha-1) fertilizers were evaluated in RCBD with three replications at Assosa district. The interaction effects of farmyard manure with nitrogen fertilizers rates were not significantly (P > 0.05) influenced total root yield of sweet potato. The highest yield was recorded by the combination 13.5 ton farmyard manure per ha with that of 45 kg of nitrogen per ha. The combination of 13.5 ton ha-1 farmyard manure with 45kg nitrogen ha-1 fertilizers recorded more than minimum acceptable of marginal rate of return (393.39%). So, we conclude that applying 13.5 ton ha-1 farmyard manure with 45kg nitrogen ha-1 fertilizers benefits farmers or beneficiaries at Assosa district. In future the researchers would have to investigate the combination of farmyard manure with nitrogen rates for more than two years at Assosa area.

Abstract: Edible woody plants are important for household food security and dietary diversification in some rural areas, particularly in the dry lands, to supplement staple foods, fill the gap between seasonal food shortages, and serve as emergency food during famine, prolonged drought, or social unrest. Within traditional farming systems, they provide a set of financial, sociological, and environmental services. This research review aimed to overview the edible woody plants diversity and potential contribution to food security in Ethiopia. Published documents and journal articles were found via keyword searches in relevant literature data banks were used as data sources. About 71% (292) of edible woody plant species have edibility reports from more than one community in Ethiopia. Fruits roots, leaves, stems were the components of plant parts that are used as edible. Cultivated fruit trees that exist on the farmlands are adapted, cultivated, and managed by household members and they are used for food, fodder, shelter, fiber, cloths. Drought, overharvesting, and overgrazing are just some of the most important factors influencing the abundance and density of edible woody plants. Local communities should be encouraged to participate in the conservation and management of plant resources. There must be collaboration between government sectors, NGOs and local communities to raise the local nurseries of edible woody species and sustain promotion of their planting in Ethiopia.

Abstract: Tomato (Solanum lycopersicum) is one of the most important culinary vegetables throughout the world. Tomato crop was maintained in Ecologically Engineered field conditions at Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir, Shalimar, Srinagar, Jammu and Kashmir, India in 2019. Abiotic factors play an important role and was showed a significant positive correlation with temperature, Relative humidity, and a non-significant negative correlation with rainfall. Temperature with Biotic factors plays a significant positive correlation. Agro-ecosystem analysis of biological factors with respect to pests and beneficial insects, to understand the intricate interactions in the ecosystem, revealed that the ecosystem has created favorable conditions for natural enemies. Natural enemies were controlling tomato pests in the absence of external forces like chemical pesticides. Hence mean pest population, Myzus persicae (14.20 aphids/plant), and Helicoverpa armigera (0.96 larvae/plant) in an ecologically engineered field were significantly reduced from that of the control were 31.74 aphids/plants and 2.69 larvae/plant, respectively. Among predatory natural enemies distribution and relative abundance, the family Syrphidae was maximum followed by order Araneae and total enhancement and conservation of natural enemies population was 3.86/plant as compared to control plot (1.09/plant) was certainly helps in the minimizing the population of Myzus persicae and Helicoverpa armigera in ecologically engineered field conditions.
