Abstract

Lettuce (Lactuca sativa L.) is a green crunchy leafy conventionally soil grown vegetable consumed worldwide as food or food component. Soil grown lettuce is exposed to inorganic fertilizers, pesticides and possesses risk of pollution or contamination. Hydroponics is a soilless culture system that is used for growing lettuce alternatively. As there is no soils are used so lettuce plants become free from soil borne  pathogen and nematodes and labor for tilling, cultivating, fumigating, watering, and other traditional practices is not required in this system. A balanced nutrient solution was applied in the fresh water for the production in hydroponics system. In our non-circulating hydroponics system the lettuce plants were supported on a Styrofoam board floating on the nutrient mix in an easily available plastic bowl. Compared to the production of lettuce in hydroponics is found better than produced in the soil. Maximum fresh weight per plant was obtained 155.0gm in hydroponics system followed by 148.0gm grown in the soil at the same age. Shape, taste and size of hydroponically grown lettuces were found excellent in compared to the soil grown. After 32-35 days of culture fully grown lettuce bowls were transferred to the dining table under low light for regular consumption and it was survived another 7-10 days without changing its color, shape and taste. Thus we developed an easy to grow and environment friendly field to table technology that will be very beneficial and economic for growing lettuce anywhere in Bangladesh.
