Jack bean (Canavalia ensiformis L.) is a legume that can serve as a source of vegetable protein, potentially replacing soybeans. Efforts to enhance its growth and yield include applying goat manure. This study aimed to determine the effect of varying doses of goat manure on jack bean growth and yield. The study used a randomized complete block design. The treatments consisted of goat manure doses of 0, 5, 10, 15, 20, and 25 t ha⁻¹. Observed variables included growth components, yield components, and overall yield. The results indicated that different doses of goat manure did not significantly affect most growth variables, except for the number of leaves at 42 and 56 days after planting and plant dry weight at all observation times. However, goat manure dose significantly influenced the number of seeds per pod, the weight of 100 seeds, and the seed weight per plant and per plot. The optimal dose to increase jack bean yield was 10 t ha⁻¹.
