This study aimed to evaluate the effect of cutting age on leaf size, number of leaves, stem diameter, and leaf-to-stem ratio of Mucuna bracteata grown in dryland in Timor Island. The study was conducted from September 2023 to June 2024 District of Kupang, East Nusa Tenggara Provinsi in West Timor. The experimental design employed was a Completely Randomized Design with three treatments and seven replications. The variables observed were leaf length, leaf width, number of leaves, stem diameter, and leaf-to-stem ratio. Data collected during the study were analyzed using analysis of variance. To determine differences between treatments, Duncan's Multiple Range Test (DMRT) was applied. The results showed that Mucuna bracteata grown on dry land exhibited increased leaf size at a cutting age of 180 days. At 240 days, an increase in the number of leaves and stem diameter was observed, accompanied by a decrease in the leaf-to-stem ratio. Among the treatments, the cutting age of 180 days produced the most favorable results compared to cutting ages of 120 and 240 days.Kata Kunci : Mucuna Bracteata, Growth
