In recent years the growth rates of world agricultural production and crop yields have slowed. This has raised fears that the world may not be able to grow enough food and other commodities to ensure that future populationsare adequately fed. However, the slowdown has occurred not because of shortages of land orwater but rather because demand for agricultural products has also slowed. Accordingly, the U.N. Food and Agriculture Organization (FAO) concludes that 70percent of the world’s additional food needs can be produced onlywith new and existing agricultural technologies. The consequences of failing to use these science-based technologiesand innovations will be disastrous. Food producers in industrialized and developing nations alike require technology to ensure a sustainable supply of safe, nutritious and affordable grains and animalprotein to satisfy a rapidly growing demand.() Growing plants is both an art and a science. About 95% of plants, either food crops or cash crops are grown in open field. Since time immemorial, man has learnt how to grow plants under natural environmental conditions. In some of the temperate regions where the climatic conditions are extremely adverse and no crops can be grown, man has developed methods of growing some high value crop continuously by providing protection from the excessive cold, which is called as Greenhouse Technology. So, it is the technique of providing favourable environment condition to the plants. It is rather used to protect the plants from the adverse climatic conditions such as wind, cold, precipitation, excessive radiation, extreme temperature, insects and diseases..(http://agritech.tnau.ac.in/agricultural_engineering/greenhouse.pdf)additionally, in the controlled environment of the greenhouse, organic and non-organic systems both utilize biological pest control, which decreases the amount of synthetic pesticides applied in the non-organic...
