Optimizing Nitrogen Use for Irrigated Waxy Barley

Research
As part of a larger study to determine N effects on food-barley production in the Pacific Northwest, the objectives of the present study were to determine (i) whether N applied at heading would increase lodging, yield, or apparent nitrogen recovery of furrow-irrigated two-row spring waxy barley compared to preplant N, (ii) whether varieties respond differently to available N, (iii) if ethephon would affect lodging, yield, and apparent N recovery, and (iv) whether spring genotypes could be grown successfully from fall plantings.
