Abstract:
This study was conducted to design and evaluate performance of different material as planting
bed for aquaponics system. It specifically aimed to evaluate performance of aquaponic system, to
determine the growth and yield of lettuce (Lactuca sativa L.) using different planting materials,
and to determine growth of tilapia under aquaponic system.A single factor experiment in
Completely Randomized Design (CRD) with three treatments and three replications was
conducted. Treatments used were the following: Treatment 1 (PVC), Treatment 2 (Styrofoam),
Treatment 3 (Bamboo). The study lasted for 44 days from January 15 to February 27, 2014 at the
Center for Sustainable Upland Agricultural Development, Bataan Peninsula State University,
Abucay Bataan, Philippines. The result of the study revealed that using different materials as
planting bed for aquaponic system has significant effect on growth and yield of lettuce.
Treatment 3 (Bamboo) attained the highest average of plants, number of leaves, and weight of
plants among treatment means, followed by Treatment 2 (Styrofoam) and had highly significant
difference over Treatment 1 (PVC) during first batch and second batch of lettuce production.
However, it was statically proved that there is no significant difference among treatments as to
the growth and mortality of the fishes.
