Water Spinach (Ipomoea reptans Poir) Hydroponic Kratky System at Various Levels of PbSO4 Contamination

Urban Farm DB summary

This research investigated the effect of nutrient type and lead (Pb) absorption on water spinach growth in a Kratky hydroponic system over 30 days. Plants were exposed to PbSO4 concentrations of 50, 100, 150, and 200 mg/L, with standard hydroponic (ABmix) and alternative nutrients. The study found that nutrient type significantly affected most growth parameters, with ABmix performing better than alternative nutrients. Crucially, no growth disturbance was observed due to PbSO4 contamination, and the combination of Pb concentration and nutrient type did not significantly affect growth or production, except for the number of leaves.
