Kerala state Agriculture department is promoting hi tech agriculture among farmers by providing training, subsidy and technical support to the farmers, financial assistance is also given for setting up polyhouses and green houses of minimum 400 M2.
The controlled environment/techniques in protected cultivation would be essential to grow high value crops throughout the tear. Greenhouses are structures covered with transparent to translucent materials such as LDPE, FRP and Polycarbonate sheets etc. which allows the solar radiation to pass through, but traps the thermal radiation emitted from the objects within. This creates a congenial environment for plant growth. Energy received from the sun is converted to heat within the greenhouse during the day as well as used for evaporate water during the normal transpiration of plants. The various parameters influencing plant growth such as Light, heat, CO2 and moisture could be controlled in these structures.
