Abstract
The effects of drill widths and nitrogen application levels on the growth characteristics and seed productivity of Italian ryegrasss(Lolium multiflorum Lam.) were evaluated. The experimental design was a split-plot arrangement with three replications. The main-plots were three drill widths of 15, 30 and 45cm, and subplots were three nitrogen application rates of 50, 75 and 100 kg/㏊ in early spring. Among the growth characteristics, lodging tolerance appeared to be highest in the treatment including 45cm of drill width and 50kg/㏊ of nitrogen application compared to other treatments. The numbers of stem per one square meter tended to be increased more in drill width of 15cm than in that of 30 or 45cm, but other growth characteristics were similar among treatments. In seed yield components, the numbers of spike per one square meter were getting increased according as drill width was narrower, but spike length and 1,000 seed weight were longer and heavier. respectively. The rate of ripened pains was highest in treatment including 30cm of drill width and 50kg/㏊ of nitrogen application. Maximum seed yield was also obtained in same treatment.
