【 摘 要 】

An increase production of Capsicum annuum in Nutrient Film Technique (NFT) can be done by setting Electrical Conductivity (EC) of vegetative (Va & Vt) and generative (G) phases. A greenhouse trial has been carried out using a completely randomized design with four treatments and six replications. The treatments were A = EC (Va = 1,2 mS cm-1, Vt = 2 mS cm-1, G = 3 mS cm-1); B = EC (Va = 1.2 mS cm-1, Vt = 2 mS cm-1, G = 3,5 mS cm-1); C = EC (Va = 1,5 mS cm-1, Vt = 2 mS cm-1, G = 3 mS cm-1); D = EC (Va = 1,5 mS cm-1, Vt = 2 mS cm-1, G = 3,5 mS cm-1). The result showed that the composition of EC at the initial vegetative (Va) phase 1,5 mS cm-1, middle vegetative (Vt) phase EC of 2 mS cm-1and generative (G) phase EC 3 mS cm-1had increased crop height, fruit number and chili fresh weight. The experiment indicated that the high EC starts from vegetative phase has better effect rather than only high on the generative phase.
