영어 초록

This experiment was conducted at Suwon, Korea from 2013 to 2015. The objective of this study was to establish the optimum seeding rate, and to clarify the nitrogen fertilizer level for rye seed production in central and north area of Korea. We used Korean rye cultivar ‘Gogu’ for this test. We employed a split-plot design with three replications. The main plots were designed by three seeding levels (3, 5 and 7 kg 10a-1), but other sub-plots were randomly seeded. The plots were treated with three different nitrogen fertilizer levels (3, 6 and 9 kg 10a-1). The percentage of productive tiller, number of grain per spike, fertility rate, 1 liter weight, and 1000-grain weight decreased as seeding rate increased from 3 kg 10a-1 to 7 kg 10a-1, whereas the number of spike per ㎡ increased. Therefore the grain yields of rye had less of an effect by increasing seeding rate. There was an increase in number of spike per ㎡, number of grain per spike, and fertility rate as nitrogen fertilizer level increased from 3 kg 10a-1 to 9 kg 10a-1, but grain yields significantly not affected by the interaction of seeding rate × nitrogen fertilizer levels. However, the best seeding rate and nitrogen fertilizer level for rye seed production were 5 kg and 5∼6 kg 10a-1, respectively, considering seed and fertilizer reduction and the prevention of pollution by excess fertilization.
