Abstract
A soil floating garden experiment was conducted to assess the effects of varying depths of water submergence on soil air-water relationships and plant growth. Using plastic containers as potting vessel, three depths of water submergence (T1 = -2 cm, T2 = -5 cm and T3 = -10 cm below the soil surface) were tested and three crops namely: tomato, pechay and kangkong were planted as test crops. Results showed that increase in the depth of water submergence from -2 cm to -10 cm resulted to decrease in the amount of pore spaces occupied by water and correspondingly increased in the amount of pore spaces occupied by air. Increased in the volume of air means more oxygen (air) that is available for root respiration thus resulting to better crop growth and yield response. Improved growth in terms of plant height, root length and dry matter yield of all crops were observed in the less submerged treatment, T3. At harvest, kangkong followed by tomato yielded more biomass than pechay.
