Abstract

ABSTRACT Rampai tomato (Lycopersicon pimpinellifolium) is one important vegetable in Indonesia. The production of rampai tomato increases every year, indicating a go od opportunity for the tomato in market. In the pr ocess of cultivation, fertilization is a very important a spect. Advances in technology have invented some importantagricultural inputsespecially for chemical fertilizers such as Urea, TSP, KCl, NPK, and other s. Nowadays, small scaled farmers frequently face diff iculty to get chemical fertilizers on market becaus e ofeither scarcity or high price. This condition ne eds to be well anticipated. Reducing the use of che mical fertilizers by using organic fertilizers which ispr oduced from local and cheap natural resources is a somewhat promising solution.The organic fertilizer tested in this study is an alternative fertilizer c alled Organonitrofos. Organonitrofos fertilizer is made from 70-80% cow dung and 20-30% phosphate rock, in the previous research. Both the materials are locally available in Lampung. This fertilizer then needs t o be tested to ensureits consistency on plant production . In this study, Organonitrofosfertilizerwas teste don rampai tomato plantsin pots (pot experiment).The st udy aimed (1) to test the Organonitrofos fertilize r on the response of rampai tomato plants in pots (2)red uce the useof chemicalfertilizersin the production oframpai tomatoplants.The pot experiment was conduc ted in the Integrated Field Laboratory of the Facul ty of Agriculture University of Lampung on January - A pril 2012. The experiment used Completely Randomize d Design (CR) with 7 treatment (7 combinations betwee n chemical fertilizer and Organonitrofos), 4 replic ates each. Data collected was analyzed by using ANOVA a nd followed by LSD. The variables observed were agronomic aspects (such as plant height, biomass, a nd production) and water consumption. The results showedthat,based on theplant responsevariablessuch asplant height, upper and biomasses, andcrop production, treatmentC(100% Organonitrofos with 500 0 kg/ha dose) was significantly different and bette r from every other treatment. Based on the water cons umption (evaporationand irrigation), all the treatm ents were not significantly different. However, the res earch showed that the use of 100% Organonitrofos fe rtilizer (5000 kg/ha); resulted in the highest water product ivity (yield/water consumption). This research als o showed that the use of chemical fertilizersbe could significantly reduced by using combination between chemical fertilizers and Organonitrofos. Keywords: Rampai tomato , fertilizer, organonitrofos, plants response.
