Water is a key to organizing all creatures lives and is important in many land surface disciplines such as agriculture, hydrology and environmental science (Delworth and Manabe,
1989). Especially, soil moisture is vital of importance to plant in order to maintain its life processes biologically. Water constitutes 80 to 90% of the fresh weight of most herbaceous plant parts and more than 50% of the fresh weight of woody plants.
On the other hand, increasing population and decreasing water source respectively make the use of water more sensitive. While the demanded of food is increasing with respect to world population, agricultural areas are getting smaller due to higher rural population den- sity (Josephson et al., 2014). Therefore, obtaining maximum crop production from limited agricultural areas becomes critical to have enough food for the world population. FAO report shows that maintenance of crop health is essential for successful farming for both yield and quality of produce and requires to apply good agricultural practices (GAP) for social and environmental sustainability (Poisot et al., 2004).
Mainly water management and irrigation attract the attention among GAP requirements since climate change is a menace for water sources. Study of NRDC indicates that some areas in the United States are expected to less rainfall while evaporation rates are increased with extending dry season by elevating temperature (NRDC, 2010). Thus, understanding the amount of both water loss…
