Tomato is one of the most popular and widely grown vegetable crops in the world. However, its yield and production are highly constrained by several factors in Ethiopia. The objective of this study is to evaluate the influence of staking, mulching, and organic manures on the yield and yield component of tomatoes in the study area. The study was conducted in the Boko research site of the Fedis Agricultural Research Center. The experimental design was a randomized complete block with three replications for thirteen treatments. The combined analysis of variance revealed significant differences among the treatments for all parameters. Results stated that Pm+S+Um was better than other treatments in terms of plant height, number of branches per plant, number of clusters per plant, number of fruits per cluster, average fruit weight, and marketable yield. Considering the results it can be concluded that Pm+S+Um is more efficient for better growth and yield contributing characters compared to other treatments. Accordingly, the use of Pm+S+Um advanced marketable yield by about 90.77% over the control and economic returns (801875 ETB ha-1). Therefore, Pm+S+UM was recommended for tomato production in the study area and similar agro-ecology.
