When you get your ZZZs, you cycle between REM and non-REM sleep. REM stands for rapid eye movement. During REM sleep, your eyes move quickly in different directions. That doesn't happen during non-REM sleep. First comes non-REM sleep, followed by a shorter period of REM sleep, and then the cycle starts over again.
Classes of Wheat. The many types of wheat grown throughout the world have common names such as durum, poulard, einkhorn or emmer. In the United States, there are generally six classes of wheat grown: hard red winter, hard red spring, durum, soft red winter, hard white and soft white.
Irrigation, Water for Winter Wheat. Since 2003, Nebraska producers have grown approximately 1.75 million acres of winter wheat per year. Of this total, approximately 12% or 209,000 acres were irrigated. Statewide irrigated wheat yields have averaged 63 bushels/acre, but yields of 120 bushels/acre are not uncommon, particularly in western Nebraska.
