On-station trial was conducted at the University of the Philippines Los Banos (UPLB) testing two to four varieties each of mungbean, cowpea, sweet potato, green corn and baby corn, and three to four fertilizer rates. Simultaneously, an on-farm trial was conducted in farmers' field in Bulacan [Philippines]. Irrigation water from small farm reservoir was applied when needed. Two to four varieties each of mungbean, peanut, sweetpotato and green corn, and three to four fertilizer rates, using bio-organic and inorganic fertilizers, were superimposed in cropping pattern plots. Results showed that all the upland crops evaluated can be grown after lowland rice under UPLB condition, while it is only mungbean that did not perform well under Bulacan condition. Yield performance, however, differed from each crop. Combined use of bio-organic and inorganic fertilizers gave comparable yield to that of sole inorganic fertilizer use
