Abstract

This study was conducted in order to utilize the basic data for weed control by surveying the occurrence of weed species and the degree of damages caused by those weeds occurred in cultivated Coix lacryma-jobi var. mayuen fields. Survey was carried out three times, from June to September in 2013. The weed flora was composed of a total of 98 weeds, 33 family, of which 58 species were annual, 21 species were biennial, and 19 were perennial plants. Thirty-one exotic species were included as well. Dominance was the highest with Digitaria ciliaris followed by Acalypha australis, Echinochloa crus-galli, Portulaca oleracea, Bidens frondosa etc. in order. In the PCA plot analysis, weeds occurred in C. lacryma-jobi var. mayuen fields were divided into three groups, Panicum dichotomitlorum community, Echinochloa crus-galli-Sigesbeckia pubescens community and Acalypha australis community. Yield of C. lacryma-jobi var. mayuen was reduced 60% in no weeding plots comparing to that in weed management plots.

율무밭에 발생하는 잡초발생양상과 잡초로 인한 피해정도를 파악하여 율무밭 잡초방제의 기초자료로 활용하기 위하여 2013년 5월부터 9월까지 3회 조사하였다. 율무밭에 발생하는 잡초는 33과 98종으로 일년생잡초가 58종(59.2%), 월년생잡초 21종(21.4%) 그리고 다년생잡초가 19종(19.4%)이었다. 이 중 외래잡초는 31종이나 덩굴성 외래잡초인 둥근잎유홍초, 미국나팔꽃, 둥근잎나팔꽃 등의 발생이 많았다. 우점도가 높은 잡초로는 바랭이, 깨풀, 돌피, 쇠비름, 미국가막사리 등이었으며, PCA 분석한 결과, 3개 그룹(미국개기장 군락, 돌피-털진득찰 군락, 깨풀 군락)으로 나눌 수 있었다. 잡초방임구에서 율무의 수량감소는 잡초관리구에 비하여 60% 감소하였다.
