Urban Farm DB summary
A hydroponic experiment in Indonesia tested the effect of plant growth regulators on water spinach (kangkung, Ipomoea aquatica) yield. Treatments included a control (AB-Mix), IAA (indole acetic acid) at 0.5 ppm, BAP (benzyl adenine purine) at 0.5 and 1.0 ppm, and combined IAA/BAP at 0.5/1.0 ppm, measuring leaf number, plant height, antioxidant content and water content. Morphological growth was most optimal under 0.5 ppm IAA, while 1.0 ppm BAP produced the shortest average plant height, fewest leaves and shortest root length. Chlorophyll testing showed 0.5 ppm IAA had the highest total chlorophyll content, averaging 9.55 μg/ml, and the authors conclude 0.5 ppm IAA had the most positive effect among the treatments tested.
