Abstract

To investigate the domestic seed production potential of Italian ryegrass, it was sown in autumn in the southern region and harvested in the spring of the following year to investigate the productivity and quality of seeds and straw. Italian ryegrass (Lolium multiflorum Lam.) 'GreenCall' variety was sown in Jinju, Gyeongnam in the fall of 2020 with three seeding rates (20, 30 and 40 kg/ha). The experiment was arranged consisted of a randomized block design with three replications. The ryegrass was sown on October 17, 2020, and the harvest was on May 31, about 60 days from the heading stage. The heading stage of Italian ryegrass was April 28, and there was no difference among treatments. Plant height was significantly shorter in the 40 kg/ha seeding treatment group, and there was no significant difference in the remaining treatments. The resistance of lodging, disease, and cold did not show significant differences among treatments. Spike length and number of seeds per spike were highest at 20 kg/ha seeding amount, and there was no difference in the remaining treatments. The seed yield was the highest at 1,956 kg/ha in the 20 kg/ha seeding rate, and there was no difference in the 30 and 40 kg/ha seeding rates. The dry matter content of seeds and straws was 45.60 and 41.83% on average, and there was no significant difference among treatments. The amount of remaining straw after seed harvesting was found to be 7,689 kg/ha on average on a dry basis, and it was high in the 40 kg/ha sowing area, but there was no significant difference among treatments. According to the above results, it was found that it is most advantageous to sow at 20 kg/ha when producing Italian ryegrass seeds through autumn sowing in the southern region.

이탈리안 라이그라스의 국내 종자 생산 가능성을 조사하기 위해 남부지방에서 가을철에 파종하여 이듬해 봄에 수확하여 종자 및 짚의 생산성과 품질을 구명하고자 수행하였다. 이탈리안 라이그라스(Lolium multiflorum Lam.) '그린콜' 품종을 2020년 가을에 경남 진주지역에 파종 하였다. 처리는 3처리의 파종량(20 kg/ha, 30 kg/ha, 및 40 kg/ha)을 두고 난괴법 3반복으로 수행하였다. 시험구의 파종은 2020년 10월 17일에 하였으며 수확은 출수일로부터 약 60일째인 5월 31일에 하였다. 출수기는 4월 28일로 처리 간에 차이는 없었다. 초장은 40 kg/ha 파종량 처리구에서 유의적으로 짧았고 나머지 처리는 차이가 없었다. 내도복, 내병성 및 내한성은 처리간에 유의적인 차이가 나타나지 않았다. 이삭의 길이 및 이삭당 종자수는 20 kg/ha 파종량에서 가장 높았으며 나머지 처리는 차이가 없었다. 종자 수량은 20 kg/ha 파종량 구에서 1,956 kg/ha로 가장 많았으며 30 및 40 kg/ha 파종량에서는 차이가 없었다. 종자 및 짚의 건물함량은 평균 45.60% 및 41.83%으로 나타났으며 처리간 유의적인 차이는 나타나지 않았다. 채종 후 남은 짚의 수량은 건물기준 평균 7,689 kg/ha로 나타났으며 40 kg/ha 파종량구에서 높게 나타났으나 처리간 유의적인 차이는 없었다. 이상의 결과를 종합하여 볼 때 남부지역에서 가을 파종을 통한 이탈리안 라이그라스 종자생산 시 20 kg/ha로 파종하는 것이 가장 유리한 것으로 나타났다.
