초록

The test conducted in this study was carried out for three years from 2013 to 2015 to investigate the optimal level of seeding amount and nitrogen fertilizer application to cultivate and produce the seeds of rye in Jangsu province, Jeollabuk-do. The variety of forage rye used in this experiment was ‘Gogu’, developed by National Institute of Crop Science, Suwon, Korea in 2004. The seeding rate was four levels (3, 5, 7 and 9 kg 10a-1, respectively) while nitrogen fertilized with respective amounts of 0, 3, 6, and 9 kg 10a-1. In Jangsu, the number of spike per ㎡ and lodging ratio were increasing, while fertility rate, 1 liter weight, 1000-grain weight and seed productivity were decreased by increasing of seeding rate from 3 kg 10a-1 to 9 kg 10a-1. There was an increase in the number of spike per ㎡, culm lengh, the number of grain per spike, lodging ratio and seed productivity, while productiove tiller, 1 grain weight, and 1 liter weight were decreased by increasing nitrogen fertilizer level from 3kg 10a-1 to 9 kg 10a-1. The best seeding rate and nitrogen fertilizer level for rye seed production were 5 kg and 6 kg 10a-1, respectively, considering plant lodging, seed and fertilizer reduction and the prevention of pollution by excess fertilization.
