Growth and Yield Characteristics of Foxtail Millet, Proso Millet and Sorghum According to Sowing Date in Middle Area in Korea

Abstract

In order to investigate optimum and marginal sowing date of foxtail millet, proso millet and sorghum in middle area (Anseong, Gyeonggi province) of korea, four levels of sowing date [(May 15(1st), June 6(2th), June 26(3th), July 13(4th)] with mulching and non-mulching were treated in this experiment. We used three crops of foxtail millet, proso millet and sorghum with four varieties of Samdachal, Samdamae, Kyeongkwan1, Hwanggeumjo in foxtail millet, Leebaekchal, Manhongchal, Hwangsilchal, Hwanggeumgijang in proso millet and Nampungchal, Hwanggeumchal, DS202, Moktaksusu in sorghum achieved from RDA. In culm length, sowing date of June 26 was the highest in all varieties of foxtail millet, proso millet and sorghum. Sowing date of May 15 showed the highest ear length in foxtail and proso millet, whereas the highest ear length was obtained from sowing date of June 26 in sorghum. In numbers of leaf, sowing date of May 15 showed the highest in all three crops of foxtail millet, proso millet and sorghum. Days from sowing to heading date were reduced in Samdamae, Kyeongkwan1 and Samdachal as sowing date was late. In Hwanggeumjo it was reduced from the sowing date from May 15 to June 26, but it was same days was taken between June 26 and July 13 sowing date. Days from sowing to heading date of four varieties in proso millet were reduced as sowing date was late. Days from sowing to heading date in sorghum were reduced as sowing date was late, whereas it was increased the 4 th sowing date of July 13. There were no significant differences in growth and yield characteristics between mulching and non-mulching in four varieties of foxtail millet, proso millet and sorghum with four varieties. The highest grain numbers per panicle, 1000 grain weight and yield per 10a were obtained from sowing date of June 26 in four varieties of foxtail millet, proso millet and sorghum. In sowing date of July 13, all varieties of foxtail millet, proso millet and sorghum were not able to be ripened because of late sowing except Hwnaggeumjo, Manhongchal and Hwanggeumgijang.

Evaluation of the suitability of potato cultivation areas in South Korea based on climate and soil conditions

“…However, there is a disparity between rice supply and demand because of an increase in rice production. Hence, there has been an effort to flexibly use paddy fields for stable rice supply and enhance food self-sufficiency by producing (or rotating) other crops in paddy fields [4]. For example, feed value, harvesting time, and sowing period were compared under forage cropping systems [5,6].…”

“…In this analysis, a geographic information system (GIS)-based analytic hierar-chy process was used [16,18]. Studies concerning uplandpaddy rotation has evaluated the effect of growth and yield on reclaimed tidal land [19], and on foxtail millet, proso millet, sorghum, and rice [4].…”

Effects of Seeding Date and Polyethylene Film Mulching on the Yield Potential and Agronomic Characteristics of Proso Millet (Panicum miliaceum L.) in Miryang, Korea

“…그러나 우리나라에서 기장 재배는 제주도 를 중심으로 재배되고 있으며 면적은 2,340 ha(2012년)에 생산량은 2,240톤 정도 추정하고 있다 (Kim, 2014). 기장의 표준 재배 기술이 정립되어 있지 않아 지역별 수량성이 다 양하다 (Yoon et al, 2015). 특히 잡곡에 있어서 1960년 후 반 전국에서 연구된 팥, 조, 녹두, 메밀의 파종 한계기는 7 월 20일～8월 10일 경으로 편차가 크고, 대부분 재래종으 로 시험되어 최근 육성된 신품종과의 생육반응에 차이가 심하다 (Ko et al, 2015).…”
