“…Numerous studies have been conducted on root zone temperature regulation methods and strategies [ 6 , 7 , 8 , 9 , 10 , 11 ]. Furthermore, some studies have analyzed the effects of root zone temperature on crop physiology and ecology [ 12 , 13 , 14 , 15 ], nutrient absorption [ 16 ], and yield [ 15 ]. Some studies confirmed that root zone temperature regulation positively affected crop growth [ 17 , 18 , 19 ], and the irrigation water temperature was one of the main factors affecting root zone temperature.…”
