When facing crisis, coffee growers are diversifying by cultivation of cash crops as new intercrops for alternate sources of revenues. Growing vegetable intercrops is one option in order to obtain maximum benefits of idle existing space, season, soil, moisture, nutrients, and to increase the productivity per unit of land. The objectives of the study were to show the effect of goat manure on the growth and yield of vegetables and to show the benefits of manure application on vegetable as intercrops in young coffee plants. The study was located in Sumberjaya West Lampung, at the altitude of 735 m asl, and conducted from December 2007 to June 2009. The treatments were arranged in a split plot design where the main plot was three dosages of goat manure (0, 5, and 7.5 ton/ha) and the subplot was three types of vegetable crop rotation (legume-legume, legume-non legume, and non legume – non legume), which were implemented for four consecutive plantings. The legume vegetable were green bean (Phaseolus vulgaris L.) and yard long bean (Vigna sinensis L), while the non legume vegetable were cherry tomato or “rampai” (Lycopersicum pimpinellifolium L), chilly pepper (Capsicum anuum L), and eggplant (Solanum melongela L.). Results showed that goat manure increased the growth and productivity of vegetables intercropped within young coffee plants. The yield gain varied between 2.7 to 5.1 times greater at 7.5 ton manure per ha than control. The revenue/cost (R/C) ratio was up to 1.8 with the manure application of 7.5 ton/ha. Organic matter was highly correlated with the yield of legume vegetable and was correlated with the yield of non legume vegetable crops. The benefit of goat manure was not only to provide essential trace nutrient needed by the plant but also to improve soil structure, and this effect lasted until the subsequent vegetable growing season. Keywords: goat manure, vegetable inter-crops, growth and yield
