Abstract

The number of irrigated acres in South Dakota is approximately 0.5 million acres. Water development plans could increase irrigated acreage four to five times causing an additional demand for electricity. Utilities pay more for electricity used during peak demand and this cost is passed on to consumers. To evenly distribute demand, some utilities are experimenting with irrigation scheduling to avoid peak usage during the day and offering lower electrical rates to participants. Another method to distribute electrical demands could be growing a crop with lower water requirements or one which has requirements earlier in the growing season and matures before the peak electrical demand months of July and August. Wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) have an earlier water requirement as well as a lower water requirement as compared to corn. However, a problem with irrigating small grains is the possibility of lodging. The purpose of this research was to study the effect of ethephon applied at different growth stages of irrigated spring wheat varieties on morphological characters associated with lodging, grain quality and yield.
