Abstract:

This study assessed the growth, yield and profitability of sweet pepper and pechay grown in a simple, locally de.signed re-circulating hydroponics system (RHS) provided with coarse river sand and coco-coir dust as aggregates at different ratios. The system consisted of6 pans (40-cm wide, 2.2 m long, 10 cm deep) made of galvanized iron (G.l.) sheets. The nutrient solution is delivered from a plastic drum by gravity to the aggregates through a system of polyvinyl chloride (PVC) pipes provided with small holes. Each end of the pan is provided with a hole where excess solution drains into a collecting container, which is then re-circulated back into the drum. The performance of the crops under this system was compared to those grown under the conventional (soil-grown), and Simple Nutrient Addition Program (SNAP) hydroponics system.
