Effects of Treated Municipal Wastewater on Oat Forage and Grain1

Abstract

Abstract

Experiments were conducted at Tucson, Arizona to study some effects of treated municipal wastewater on growth, yield, and quality of oats (Arena sativa L.) grown for pasture forage and grain. No differences were observed in plant height, tillers per plant, green forage yield, and total protein between forage grown with well water plus suggested amounts of N, P, and K and forage grown with wastewater alone. Oats produced more dry forage when grown with well water plus suggested N, P, and K than when irrigated with wastewater. Wastewater produced forage with higher moisture content than well water plus N, P, and K. When grown for forage, cultivars differed in plant height, dry forage yield, and total protein content.

Oat grain data showed no differences between irrigation and fertilizer treatments for maturity, plant height, panicles per unit area, grain yield, and total protein. Well water plus suggested N, P, and K resulted in fewer seeds per panicle and heavier seeds than wastewater. Cultivars differed in maturity, plant height, panicles per unit area, seeds per Panicle, seed weight, grain yield, and total protein. Treated municipal wastewater can be utilized to produce oats with grain yields and forage and grain protein contents approximately equal to those obtained when oats are grown with well water and suggested levels of N, P, and K.
