Uji Kemiringan Talang Sistem Fertigasi Hidroponik NFT (Nutrient Film Technique) Pada Budidaya Tanaman Selada(Lactuca Sativa)

Abstract

Nutrient Film Technique (NFT) is a new technological in hidroponics. In this system, a part of root deep on the water have fertilizer and other part upon the water which sirculating above 24 hours. The lining of the water is slight, about 3 mm, so its like film. The research of NFT irrigation was carried out to study on Electric Conductivity (EC) uniformity and pH of nutrient liquid as well as effective 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 9% gradient of gutter resulted in better yield than the 6% gradient. The research was concluded that 9% gradient of gutter was the most effective.
