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.
