摘要

Moisture stress is a major factor affecting coffee yield. We investigated the effect of micro-catchment structures on runoff, soil loss, and coffee yield at Melko, southwest Ethiopia. Methods: We constructed runoff plots using a randomized complete block design with three replications. A total of twelve (12) standard runoff plots of size 16 m by 8 m were established, and 32 coffee seedlings were planted with a spacing of 2 m by 2 m under the recommended shade trees. The treatments, control (without structure), half-moon, full moon, and soil bund were applied. Coffee tree growth parameters, run-off, suspended sediment, and about 36 composite soil samples (4 treatments, 3 depths, and 3 replications) were collected for analysis. The collected soil samples were subjected to normal laboratory procedures for the analysis of selected soil physicochemical characteristics. Results: The control plot showed significant differences (p < 0.05) in runoff and soil loss as compared to other treatments. Conversely, soil moisture and clean coffee yield were significantly different under the soil bund and full moon, respectively. Furthermore, total nitrogen showed significant differences (p < 0.05) under soil bund as compared to other treatments. Whereas, plant height, internode, number of middle branches, and total primary branch numbers were significantly higher under a full moon as compared to other treatments. Conclusions: Micro-catchment structure construction in coffee farms can markedly enhance coffee yields by mitigating soil erosion, preserving soil moisture, enhancing plant growth and reducing the effect of climate change, hence promoting sustainable agriculture and contributing to the attainment of Sustainable Development Goals.
