Abstract

Abstract Irrigation water was applied at various growth stages to peas ( Pisum sativum L.) grown for processing. Irrigation increased all growth characters measured, extended blooming and pod setting, and delayed maturity 1 to 7 days. Irrigation at pod filling increased yield more than irrigation at any other growth stage and produced the greatest yield increase per cm of water applied. Irrigated peas were of lower quality for processing than non-irrigated peas.
