Growth of Vicia tetrasperma and V. hirsuta as Affected by Seeding Condition and Estimated N Production

Abstract

This study was established to investigate the effects of seeding depth and seeding time on the emergence, growth, and N production of Vicia tetrasperma and V. hirsuta in 2007 and 2008. All seeds of both species were gathered from Dangjin, Chungnam in late June of 2005 and stored for two year at room temperature. Both V. species began to germinate at the end of June, passed the winter with the seedling stage, rapidly increased their height in April and May, were in full bloom in May, and then withered after entering mid-June. V. hirsuta had higher emergence rate and growth compared to those of V. tetrasperma. The optimum seeding time and seeding depth for a cover cropping was from late August to early September and from 1 to 5 cm, respectively. V. tetrasperma and V. hirsuta had a satisfactory growth and provided 43.8 and 55.4 kg ha-1 of N, respectively.

“…최근 우리나라 겨울철에 자생하는 콩과 나비속 식물인 얼치기와두, 새완두 등에 대한 연구가 이루어져 왔고, 특 히 Cho et al(2009)은 이들 자생 피복녹비작물의 적국적 인 분포와 생태 그리고 피복식물 활용 가능성을 처음으로 입증하였다. 이후 얼치기완두와 새완두에 대한 발아특성 과 파종량에 대한 포장시험과 질소공급량에 대한 시험도 수행되어 그 결과를 발표하였다 (Cho et al, 2011a). 이들 피복녹비작물은 피복 정도에 따라 잡초발생 양상이 다르 고 또한 잡초억제 효과도 현저하였고 보고하였다 (Cho et al, 2011b The same letters in a column are not significantly different at 5% level by DMRT Table 2.…”
