Effect of harvest method and date on lesquerella seed yields

Field trials were conducted to compare the harvested yields of lesquerella seed obtained from windrow combining to those obtained by direct combining following spraying with a desiccant. The mean harvested yield for windrow combining was less than for direct combining. The difference was statistically significant for the detailed trials, but not for the commercial trials. Delaying crop termination by two weeks significantly increased yield regardless of harvesting method. This suggests that prolonging the season may be beneficial provided adverse weather conditions do not result in increased losses due to shattering.
