The total water-soluble carbohydrates (TSC) in orchard grass stubble accumulated during the period of cool season, and declined when the weather was hot and dry. During the period of cool season, the reserve level decreased when a new leaf emerged after the start of plant growth and then increased rapidly, however, decreased after seed ripening. Levels of carbohydrate content decreased sharply following the top-dressing applied simultaneously with the cutting. When the top-dressing was followed by the period of hot dry weather, carbohydrate reserved were often reduced to critical levels. In such weather conditions, the top-dressing on orchard grass should be restricted
