Analisis Sistem Irigasi Hidroponik NFT (Nutrient Film Technique) pada Budidaya T anaman Pakchoy (Brassica Chinensis L.)

Abstract

Nutrient Film Technique (NFT) is a new technological in hydroponics. In this system, a part of root deep on the water has fertilizers and other part upon the water which circulating above 24 hours. The lining of the water is slight, above 3 mm, so its like film. . The research of NFT irrigation was carried out to study on Electric Conductivity (EC) uniformity and pH of nutrien liquid as well as effectivity of gutters gradient application. The research was done with planting the plants in gutters that hold by styrofoam, afterwards recording data according to available parameter was carried out during crop growth. The research showed that 6 % gradient of gutter resulted better yield produce than 3 % gradient of gutter. The research was concluded that 6 % gradient of gutter application was more effective
