Frequent clipping of Dactylis glomerata after 15?, 30? and 45?day regrowth periods showed that higher foliage yields and better root development are obtained after the longer periods of regrowth. With these longer periods of regrowth, larger quantities of available carbohydrates were translocated to the roots. Clipping at 15?day intervals has as its only advantage a high percentage of protein in the harvested material. With a 30?day regrowth period higher yields of foliage, roots and available carbohydrates were obtained in a 14?hour daylength compared with a 10?hour daylength. An alternating day/night temperature of 22,2°C/15,0°C was more advantageous for foliage production, root development and the storage of available carbohydrates than a day/night temperature of 30,0°C/15,0°C.
