Abstract: The growth of spring wheat was demonstrated in response to irrigating exclusively and conjunctively with uncontaminated river water and salinized drain water. The drainwater came from a shallow aquifer which had elevated levels of boron. Four water treatments were imposed representing a range of water qualities, and the growth response was evaluated 4 times during the growing season. Results rejected the hypothesis that day-time irrigation with drainwater especially will significantly reduce growth of spring wheat. This supports the conclusion of previous studies that the use of drainwater for irrigation is a viable emerging technology for improving overall irrigation efficiency and reducing the mass output of salts and trace elements from irrigated areas.
