Effects of Clipping on the Performance of Spring Barley (<i>Hordeum vulgare</i> L. emend Lam) Seeded in October¹

Abstract

Abstract A 4‐year experiment was conducted to study some of the effects of clipping on the yield and quality of simulated pasture forage and grain from ‘Harlan’ spring barley planted in October and grown under irrigation at Mesa, Ariz. Four treatments (0, 1, 2, and 3 clippings at the onset of jointing) were evaluated in a replicated randomized complete block design. Forage and grain harvests were made with small‐plot equipment. Clipping two times by late January reduced plant height, eliminated lodging, and produced maximum yields of quality grain. In addition, the pasture forage provided an economical source of protein and digestible laboratory nutrients (D.L.N.).
