Abstract
Abstract Cotton plant ( Gossypium hirsutum L.) phenology was observed in a sheltered environment for six different planting dates and compared to cotton grown in an unsheltered area to isolate the effects of wind movement on cotton phenology and plant stress. The shelters consisted of a snow fence which provided a 35% reduction in wind velocity 0.2 m above the crop for the season. Partially sheltering the cotton from wind resulted in increased plant height, earlier squaring, earlier boll set and more bolls and biomass when compared to the unsheltered cotton. The increase in biomass and plant growth for the sheltered cotton required more water as the season progressed than the unsheltered cotton produced without supplemental irrigation. The study shows that wind and water uptake should be considered in crop models.
