Growth of Cruciferous Crops under Different Levels of Aeration

THE GROWTH of Pakchoi and Chinese cabbage grown in deep water culture at different rates of aeration was investigated at the Tropical Vegetable Research Center, Kasetsart University. Vegetables were applied with different rates of aeration: continuous, 15 min/h, 15 min/2 h, 15 min/3 h, and without aeration.

Continuous Aeration Gave Higher Oxygen Levels but Not Faster Growth

The solutions treated with continuous aeration had higher oxygen level than the others. The highest dry weights of Pakchoi and Chinese cabbage were obtained when grown in solution with 15 min/h or 15 min/3 h aeration.
