| dc.description.abstract | Growing of lettuce using hydroponics system is increasing nowadays. However, the production is limited by the availability and high cost of inorganic nutrient solution. Alternatives to inorganic nutrient solutions such as organic based solutions were tested in this study under passi hydrponics system. The following treatments were evaluated: 50% fish amino acid (FAA), 100% FAA, 50% fermented plant juice (FPJ), 100% FPJ, 50% vermicompost tea (VCT), 100% VCT, recommended rate of inorganic nutrient solution (INS) and water (Control). Lettuce was grown for 30 days in styrofoam boxes maintained with 7 cm depth of nutrient solutions. Applications of INS, 50% and 100% VCT significantly improved plant height, number of leaves, width of leaves, weight of lettuce, yield per box, chlorophyll and dry matter content than the water treatment. In addition, these treatments had better sensory and postharvest characteristics than the lettuce applied with water alone. The use of FAA and FPJ at 50% and 100%concentration on the other hand produced retarded growth and early senescence of lettuce plant. For economic purpose VCT at 50% is recommended in this study as potential alternative to inorganic nutrient solution. | |
