Pakchoi [Brassica rapa ssp. chinensis (L.) Hanelt] is a popular high-value leafy vegetable in the Philippines that could be grown hydroponically. This study was conducted to evaluate the responses of pakchoi to organic nutrient solution under aggregate hydroponics system. The organic nutrient solution was a novel preparation from A. pintoi leaves, G. sepium leaves and Musa sp. peel. It was applied to the plants with or without added inorganic salts. The commercial hydroponics nutrient solution was included as control. The plants were found to be more responsive to commercial hydroponics’ nutrient solution than to organic nutrient solutions. This was expressed in terms of leaf size, plant weight and total yield.
