So, low quality saline water should be used for irrigation, particularly in some regions, especially with the rapid expansion of reclaimed lands.The term "greenhouse climate", has been used to indicate the set of environmental quantities, i.e. radiation, temperature, humidity, and CO2 concentration, in a greenhouse as they affect plant growth and development. Conventionally, greenhouse environment has been represented by a group of special average value of the above variables sampled at one or more position within a greenhouse
