A field experiment on the effects of Desmodium heterophyllum on the yield of peanut and soil fertility was conducted in the Agroforestry Research and Demonstration Area, ViSCA [Visayas State College of Agriculture, Baybay, Leyte, Philippines] in December 1987 to March 1988. Peanut and D. heterophyllum were grown under zero tillage management on hilly area. The experimental plots were laid out within the strips of four-year-old double row Gliricidia contour hedges separated by 1M in elevation on a 20 % average slope. Results indicated that yield of peanut grown in association with Desmodium heterophyllum was significantly higher than that of the control. Soil pH, percent organic matter and phosphorous content of the soil increased in all treatments. Higher accumulation of organic matter and phosphorous contents were observed on treatment with D. heterophyllum.
