Abstract

The purpose of this study is to determine the growth and yield of selected varieties of lettuce (Lactuca sativa), Carlo Rossa and LolloRossa in Aquaponics System. The study determined the (1) growth rate in terms of height (cm), (2)number of leaves and (3) yield (g). The study used two lettuce varieties as treatments, namely: T1-Carlo Rossa and T2-LolloRossa. Fifty samples in each treatment were evaluated and the mean data in each treatment were compared. In the t-test with p<0.05level of significance, results showed a significant difference between means of the height (cm) and number of leaves in the two treatments. In yield (g) T1 and T2 were comparable and the results revealed that despite the differences in the values, no significant differences were observed between means of yields. The study concluded that in terms of obtaining the higher mean height (cm) T2 –(LolloRossa) was more effective than T1 –(Carlo Rossa), while in attaining the higher mean number of leaves T1 –(Carlo Rossa) was more effective than T2. In terms of yield, both treatments can be grown in Aquaponics system. The study recommends the regular spraying of nutrient solution to lettuce plants for at least 3 times a day thereby limiting the culture duration in 30-40 days. Verification trial should be performed to validate results. The study is indeed a great advantage to numerous farmers, as well as to our environment because the Aquaponics system is advocating a safe and clean production system, due to its full reuse of waste and nutrients.
