That’s Zac B. Sarian, your blogger, standing beside the robust Japanese Saluyot planted in the bottom half of soft drink bottles, submerged in water. The technology was developed by Dr. Eduardo Paningbatan Jr.

DR. EDUARDO PANINGBATAN JR., a retired soils professor and research at UP Los Baños, has developed a simple aquaponics system highly suitable for use in urban farming and gardening. He displayed his system during a recent Agri-Bazaar at the Quezon Memorial Circle in Quezon City. With his system one can grow vegetables and other plants with their roots submerged in wate.

Normally, we know that most vegetables (except kangkong) will not thrive in water because they will be deprived of oxygen. Well, Dr. Paningbtan has a new technique that will enable the vegetables to thrive in water.

In the model that he displayed at the Agri-Bazaar, he used a blue plastic drum container that is halved lengthwise. This is filled with water. Atop the halved drum is slotted plastic matting. Holes are made into which the plants planted in the bottom half of soda bottles are installed. The plants are submerged in water, held upright by the plastic cover of the half drum. Why don’t the vegetables wilt? Well, Dr, Paningbatan adds some algae in the water which provide the dissolved oxygen needed by the plants. He also puts some small tilapia to eat wrigglers in case mosquitoes are present. Of course, he also adds his special nutrient extract to nourish his plants.

One example of his very healthy plants submerged in water is the Japanese variety of Saluyot. The plants grow robust and blemish-free in the water. Other vegetables and herbs can also be grown in the same manner.
