Processing quality characteristics of three different long-grain rice cultivars (CICA-8, Labelle, Lemont) grown under three water management regimes (flood, sprinkle when soil matrix potential [SMP] was less than -0.2 bar, sprinkle when SMP was less than -0.5 bar) were tested. Brown rice yields varied between cultivars but were not affected by water management. Milling yields were higher in flooded rice than sprinkler-irrigated rice, but effects within cultivars were variable. Total milled yields were higher for Labelle and Lemont than for CICA-8. Amylose content, which ranged between 26.6 and 29.7%, was not affected by cultivar or water management. Amylograms indicated that CICA-8 had higher viscosity values, less breakdown, and greater setback than Labelle and Lemont. CICA-8 was judged to have lower sensory quality in a rice pudding for the attributes of texture, moisture, and acceptability. There was no overall effect of water management on sensory attributes, but sprinkler-irrigated Labelle was judged higher than flood-irrigated Labelle for the attributes of texture and consistency.
