Our recent studies have shown that low light intensity significantly depressed cotton (Gossypium hirsutum L.) leaf photosynthetic rate and reproductive growth, increased fruit shedding, and reduced lint yield and fiber quality. The effects of shade (low light intensity) on cotton growth and yield have been closely associated with the amount of light reduction, and the timing and duration of shade. However, little is known about effects of shade on nonstructural carbohydrates and mineral nutrient status of field-grown cotton. A three-year study was conducted in 1993-1995 under field conditions in Fayetteville, Arkansas to determine the effects of shade at different growth stages on nonstructural carbohydrate (hexose, sucrose and starch) and mineral nutrient contents in cotton plant components.
