ABSTRACT
The design of environmental control systems for plants is complicated owing to the interaction of many environmental variables affecting growth and production. The clear necessity of matching food production to the needs of the world’s population requires the accurate knowledge of the factor limiting primary production. Therefore, the environmental factors that limit agricultural production and physiological responses of plants to environmental stresses need to be identified and understood. The fluctuating and interacting natural environment makes it nearly impossible to analyze the effects of various climatic factors on plant behavior. The most appropriate solution for this problem is to move research into a plant growth structure with partial or complete environmental control, then this well maintained chamber is named as controlled environment greenhouse or automated greenhouse (Tiwari, 2003).
