  • Nitrogen fertiliser and rotation length play a critical role in keeping adequate pasture cover going into summer. Nitrogen applied in early summer also plays a role in ryegrass persistence. As a rule of thumb the greater the tiller density going into summer the greater will be the tiller density at the end of summer. DairyNZ research shows nitrogen applied now helps convert perennial ryegrass pastures from seed head producers back to producers of high quality leaf. Seed head formation is a death sentence for these shoots because grazing or mowing removes their growing points. Nitrogen stimulates the development and growth of new shoots, and therefore high quality leaf. Nitrogen is more important than water for summer ryegrass growth (except under drought conditions), with nitrogen boosting shoot numbers by 37% compared with less than 18% for irrigation. Nitrogen also helps to increase the amount of feed so that it’s easier to have a longer rotation length in summer. It does not increase the rate of leaf emergence, it just creates bigger leaves
