Abstract

Abstract A number of organic vegetable farmers in Central Luzon Philippines grow organic vegetables year round. However most of them usually apply the required amount of organic fertilizer only once during planting. Hence nutrient requirement of vegetables during vegetative or reproductive stages are no longer available. This condition seriously affects the growth and development of vegetables and subsequently affecting the yield performance that may result to low yield. In order to reduce the potential effect of nutrient deficiency on organic vegetable production the research aims to a establish frequency of organic fertilizer application employing split application and b determine the yield performance and net return based on the different treatments used. The research was conducted for two consecutive dry seasons 2012 and 2013 under full organic operation system. Results of the study showed that two split application of organic fertilizer gave higher yield 5.10 tha compared to single application 3.08 tha and three split application 3.48 tha for native bittergourd. Tomato had the highest yield 29.82 tha at two split application of organic fertilizer during the first trial. Yield performance during the second trial showed a comparable yield at two split application 39.40 tha and three split application 36.87 tha of organic fertilizer. Cost and return analysis on native bittergourd showed that two split application of organic fertilizer gave high return on expenses of 167.91 and 137.21 during the first and second trial respectively. Whereas tomato had the highest return on expenses on basal application of organic fertilizer at 430.85 during the first trial while two split applications in the second trial recorded a return on expenses of 587.21.
