Abstract
A foliar fungicide efficacy trial was established at the University of Nebraska-Lincoln South Central Agricultural Laboratory near Clay Center, NE. Grain sorghum hybrid NC+ 7R83 was planted on 18 May in 30-in. rows with a target population of 90,000 plants/A. The trial area was disked with a crop history of five years of continuous corn. Eight treatments and a non-treated control were replicated six times in a randomized complete block design. Each plot was four rows (10 ft) wide by 40 ft in length. . . . There were no significant differences in stay green. Stay green percentages ranged from 62.5% to 66.1%. There were no significant differences in 1,000-count kernel weights. 1,000-count kernel weights ranged from 0.92 oz (Quadris 2.08 SC, 6 fl oz at boot) to 0.99 oz (Quilt 1.66 SC, 10.5 fl oz at boot). There were no significant differences in grain moisture at harvest. Grain moisture ranged from 16.2% to 16.4%. There were no significant differences in yield among all treatments. Yields ranged from 142.7 bu/A (nontreated control) to 154.7 bu/A (Quilt 1.66 SC, 10.5 fl oz at boot). Data were analyzed using the Waller-Duncan k-ratio t Test (P > 0.05).
