This study was conducted to determine the effects of five organic nutrient solution concentrations (0.5%, 1%, 2%, 3%, 4%) extracted from animal and plantswithKnop’ssolution as control,on water spinach grownin non-circulating hydroponics. The pot experiment was carried in green house. The pots werelaid out in a randomized complete block design withthree replications. The results showed that organic nutrient solution exerted positiveeffect on the growth, yield and quality of water spinach in whichconcentrations of 3% and 4% yieldedhighestyield. Organic solution treatments showed higher quality compared with inorganic solution treatment (Knop’s solution), i.e.NO3-content was nearly 6 times lower compared with the control, while levelwassignificantlyhigher. The results suggestedthat organic solution concentrationsof 3% and 4% are suitable for growing water spinach in non-circulation hydroponic method.
