GROWTH AND PRODUCTION OF WATER SPINACH ( Ipomea aquatica Forsk.) IN VARIOUS TYPES OF HYDROPONIC NUTRITION SYSTEM NFT (Nutrient Film Technique)

Efforts to increase the production of kale with a hydroponic cultivation system, addition nutrients is absolutely necessary for both macro and micronutrients. In using AB mix nutrients, use other alternative fertilizers in needs be big concern so that it can suppress inorganic fertilizers. The purpose this study was determine effect giving various types nutrient compositions cow urine on growth yield water spinach plants Nutrient Film Technique (NFT) system . design used single factor randomized block (RAK) 4 levels treatment consisting N 1 (100% ), 2 (75% + 25% Cow Urine), 3 (50% 50% (25% 75% Urine). results showed provision nutritional significantly affected productivity except variable number books. Plant given composition urine) markedly lower all observed variables, while best shown 100% but not different urine. also show has been able replace nutrition.
