Abstract
Abstract The commercial dry bean ( Phaseolus vulgaris L) production system in Alberta requires irrigation and the viny cultivars currently used in this production system are prone to outbreaks of white mold caused by Sclerotinia sderotiorum (Lib.) de Bary. The use of beans with an upright growth habit has potential for alleviating the disease problem, but the narrow profile of the upright beans may warrant a different planting pattern to achieve high yield. A study was undertaken to determine the effect of between‐ and within‐row spacings on the occurrence of white mold and seed yield of upright beans. An experimental navy bean composite with upright growth habit, and a susceptible control Red Mexican, UI 37, were evaluated using three between‐row (BR) and three within‐row (WR) spacings in presence or absence of white mold during a 2‐year period. The BR and WR spacings had no effect (P > 0. 05) on disease occurrence in the inoculated upright composite or in the viny control. Regardless of BR and WR spacings, the upright composite had less (P < 0. 01) disease than the control in both years. In general, large differences (P < 0. 05) were found between the upright composite and control spacing treatments in the presence or absence of white mold. BR spacing had a significant effect on seed yield, but WR spacing did not. In most cases, increasing plant density by reducing BR spacings resulted in higher seed yields. These findings suggest that producers may gain in seed yield without increasing risks for white mold occurrence by changing from viny to upright beans and planting in narrower rows.
