The study was conducted at the Newly Acquired Land ofDon Severinoo Agricultural College, Indang, Cavite from December 1990 to March 1991. This study was conducted to evaluate the performance of the surface runoff collector under diversified cropping scheme. Water application in the field study was considered in the absence of rainfall during the conduct of the study. Source of water from the nearby stream was utilized. The application of water helped in the creation of surface runoff water. Longest water retention time was obtained from cylindrical plastic container at 50 hours for 0.5 centimeter outlet discharge diameter. Shortest water retention time was obtained from collector made of polyethelene bag at 45.5 hours for 1.5 cm outlet discharge diameter. Statistical analysis showed that the water retention time were not significantly different from each other at different outlet discharge diameters and collector materials. Soil moisture readings at saturated soil condition monitored at different distances from the center of the collector were 70.76, 70.71, 70.63 and 70.79 percent for 40, 60, 80 and 100 cm., re.5pecti7ely. At field capacity, `1.2 I of 67,90., 65.35, 63.22 and 61.27 percent for 40, 60, Fin and 100cm, respectively, were obtained.
