The sustainability of some vegetable crops in contoured, sloping areas of Claveria, Misamis Oriental [Philippines] with application of organic fertilizers was studied. A four-year production of Baguio beans-sweet pepper-tomato-crucifer was undertaken. Hedgerows of mulberry were established in the experimental area. Findings showed that alley cropping plus chicken manure (CM) and plant compost increased yield. Solanaceous crops had significantly higher yields when given 2t CM per hectare singly or in combination with plant compost [i.e., corn cobs (cc), coffee pulp (CP)]. The same trend was observed in leguminous crops (Baguio beans). Yield was sustained up to two years, after which, it declined. Hence, marginal benefit-cost ratio (MBCR) value were high during these two croppings. Decrease in yield was attributed to below ground competition between the mulberry and the regular vegetable crops. Therefore, frequent pruning was necessary. While application of chicken manure checked soil acidity, continuous cropping however, reduced the soil's organic matter and phosphorus content. Inclusion of crucifers in this cropping pattern was not viable because it was susceptible to soft rot disease
