Study on performance of water-organic fertilizer The trade name plus Vochong on growth of lettuce green นโอ็ค grown in hydroponics systems. By Deep Flow technique Technique (DFT) bring lots of water and organic fertilizer in water 1: 50 times prior to passing through the filter with different methods. A Randomized Trial is planned Complete Block Design (RCBD) with individual redundant thamen 4 5 3 treatments at 1 use the nutrient solution formula Enshi is the processes that govern the treatment of organic fertilizer solution 2 does not pass the filter the aqueous solution 3 treatments, organic fertilizer, water that has passed filter.Kamman charcoal Treatment of organic fertilizer solution at 4 of water through the filter with sand treatments at 5 solution filtered water, organic fertilizer with charcoal, sand and kamman. In each, there are treatments to control the electric conductivity (Electrical conductivity EC;) to EC is equal to 1.2-1.4 mS/cm pH value of aqueous solution equal to 5.5-6.5 make a new solution every week throughout the 4 week trial results showed that นโอ็ค green lettuce grown in nutrient solution formula, Enshi.Organic fertilizer and water through the filter with different agencies have different growth treatment that 1 nutrient solution formula, Enshi, the width of the fresh weight of leaf area, Topiary total root dry weight, fresh weight and balance. Dry weight, root treatment than other significant statistics While the treatment that the organic fertilizer solution 2 does not pass the filter and the treatments the water 4 soluble substances of organic fertilizer through the filter with sand, the quantity of chlorophyll a maximum significant statistics and found that in the treatment of organic fertilizer solution 5 water through sand and charcoal filter with kamman, the trend of a Topiary shaped in width, weight, dry weight, fresh weight and amount of fresh and dry weight, root root shoots better than in the other treatments with the use of water soluble substances of organic fertilizer.
