The polyhouses are constructed with the help of ultraviolet plastic sheets. The structure is covered with 1501 m thick plastic sheet. The structure is prepared with the bamboos or iron pipes. Iron pipe structure is costly but more durable than bamboo. The direction of polyhouse is always East to West so that the maximum sunshine is available. The house should not be constructed in shade. The size of polyhouse may differ depending on the necessity. The polyhouses are kept cold or hot depending upon the season. From the point of view of earning more profit only such off-season crops should be grown, which are being sold at higher prices in the market. Big hotels in cities are mostly in the need of off-season vegetables and so is the case with some prosperous people in big cities. In such areas and also in the hill and remote regions where fresh vegetables are required regularly for meeting out the requirements of security forces, the construction of polyhouses is more lucrative and is a must. The crops grown under the polyhouse are safe from unfavorable environment and hailstorm, heavy rains or scorching sunshine, etc. Crops of the polyhouse can be saved from birds and other wild animals. The humidity of polyhouse is not adversely affected by evaporation resulting in less requirement of water. In limited area of polyhouse, insects and pests control is also easy and less expensive. By adopting the modern technology of polyhouse, the difference in the demand and supply of off-season vegetables and fruits etc. can be minimised. This facilitates in maintaining the quality of the product also. Benefits: Technical: The determination of the most cost-effective method for limiting greenhouse humidity The development of a new and effective way of controlling plant irrigation, which could have application on open field cultivation as well Tuning heating system efficiency with the phase of the protected crop Standardisation of conventional sensors and development of new sensing techniques to enable "quality control" in prime production Advanced concepts of Information technologies to provide a vehicle for speeding up the transfer of research results to practice Scientific: The development of a method of predicting plant water and nutrient requirement based on easily measured weather variables A significant advance in the simulation techniques used to predict the environment in cropped enclosures Innovative sensing of plant physiological responses, including early nonvisible symptoms of disease onset The development of on-line techniques for the real-time optimisation, cost vs quality-grade, of controlled conditions Economic: Reduction of precious water and nutrient chemicals consumption, by an amount of up to 40% in greenhouse production and ensure quality of water availability and balanced nutrient supply Optimal control of greenhouse humidity and of energy utilization will enable grower income to be maximised Environment: A reduction in pollution caused by the fertilizers contained in excess irrigation water drained to the soil Reduction of crop protection chemicals (reaching the consumer directly through the product and indirectly through the environment) by controlling humidity, early detection of diseases, and finely controlled closed irrigation systems
