Effects of Planting Density of Wanggol (Cyperus iwasaki Makino) on Dry Cortex and Medulla Yield at Rice Field
남부 지방의 답전작 재배에 적합한 왕골의 재식밀도를 구명코자 다수성 품종으로 선발된 광산조생종을 공시하여 시험했다. 그 결과, 경장, 분얼수, 출수된 경수, 경태 등의 수량구성형 질은 18×18 cm 이식구에서 가장 우수하였고, 건피수량, 건수 수량에서도 18×18 cm 이식구에서 가장 우수하였다.
To determine the optimal planting density of wanggol in southern areas of Korea, Gangsan early local, the highest yielding variety was grown under four different plant density. Yield components such as stem length, number of tiller, stem diameter were highest at the plots with 18 cm row spacing and 18 cm plant spacing. Dry cortex and medulla yield were highest at the plots of 18 cm row spacing and 18 cm plant spacing. Judging from the results reported above, at optimum planting density of wanggol seemed to be 18 cm row spacing and 18 cm plant spacing.
