Plant Population & Row Width - White Mold Management

A study was established in 1999 to examine the effects of row spacing and plant population on white mold incidence. Variety, row spacing, and plant population planted in factorial design were factors used in the study. The results from the first year showed significant white mold development at three locations.

At these locations plant population significantly affected white mold incidence. Greater white mold incidence was associated with increased plant population. Neither row spacing nor the interaction of row spacing with plant population had a significant effect on white mold incidence although white mold incidence was lower in 30 inch rows than in 10 inch rows at one location.
