| dc.description.abstract | The study was conducted to evaluate the growth and yield of frillice lettuce using thermo-electric cooler (TEC) for recirculating aeroponic system (RAS) and to compare it with the growth and yield of frillice lettuce grown in RAS without TEC; and to determine the water consumption and productivity of frillice lettuce under RAS. The growing cups filled with the growing media and lettuce seeds were randomly inserted in two RAS following the statistical design and layout. Environmental and water quality parameters together with agronomic parameters (plant height, number of leaves, root mass, weight of produce, water consumption and water productivity) of plant were recorded to determine the response of lettuce. The study was laid out using the 2x2x4 factorial in CRD (Completely Randomized Design) with cooling method (Factor A) and growing media (Factor B). The data gathered were analyzed using ANOVA. Frillice lettuce in RAS with TEC gave a much taller plant height with 19.25 cm compared to 18.05 cm mean height of plant subjected to RAS without TEC. In terms of leaves, RAS with TEC were numerous with a mean value of 16 leaves and 14 leaves for RAS without TEC. Root mass under RAS with TEC has 4.30 grams/plant and 3.90 grams/plant for RAS without TEC. The weight produce in RAS with TEC was higher having 6.15 grams/plant while 4.85 grams/plant for RAS without TEC. Lettuce grown in RAS with TEC consumed 51.67 liters of water for lettuce grown in RAS without TEC consumed 52.93 liters of water. The water productivity of frillice lettuce obtained a mean value of 32.24 g/L in RAS with TEC and 24.32 g/L in RAS without TEC. | |
