초록

본 연구는 쌀겨, 보릿겨, 태운 쌀겨 및 태운보릿겨를 부추와 토란을 파종하기 전에 시용하고 이들 작물의 생육과 수량증대에 미치는 영향을 알아보기 위해 수행하였다. 이들 4가지 겨류를 처리하고 처리 후 13, 27, 41, 57일 째 조사한 결과 부추의 초장은 보릿겨수비 처리구에서는 조사 전 기간에서 무처리구보다 유의적으로 컸던 반면 다른 처리구에서는 큰 차이를 볼 수 없었다. 또한 겨류처리에 의한 부추 개체수에서도 무처리와 큰 차이가 없었다. 그러나 처리 후 57일 째 조사한 생체중은 무처리구에 비해 4가지 겨류처리구에서 약 2배 많았다. 이들 차이가 토양 화학성분과 관련성이 있는지 알아보기 위해 처리 후 57일째에 토양의 화학성분을 분석한 결과 겨류를 처리한 토양에는 유기물과 유효인산 등이 풍부하였다. 부추 예취 후 14일에 재생한 부추의 지상부 생체중은 4가지 겨류 처리구에서 무처리구에 비해 높은 경향이었으나 보릿겨 처리구에서만 무처리구에 비해 유의적으로 높았다. 4가지 겨류 처리 후 10cm 토란을 이식한 경우, 보릿겨처리구에서만 토란의 지상부 및 지하부 생장량이 무처리에 비해 증가하였다. 그러나 겨류처리 후 종자를 파종 한 경우 오히려 겨류처리에 의해 토란 수량이 감소한 것으로 보아 겨류효과는 작물의 종류 및 이식시기에 따라 다름을 알 수 있었다. Pot 조건하에서 쌀겨 및 보릿겨 처리(2,000, $4,000kg\;ha^{-1}$) 후 15일에 조사한 피, 바랭이, 명아주 및 까마중에 대한 잡초방제 효과는 아주 적었고, 포장조건하에서도 겨류처리에 의한 잡초방제 효과는 아주 적었다. 그러나 쌀겨를 ha당 4,000kg 처리 수준에서는 배추와 쑥갓에서 각각 62.6%와 37.2% 생육 저해가 나타났고 그 밖의 옥수수, 호박, 오이 및 부추의 경우에서는 0~19.6%의 생육저해 현상이 나타났다. 보릿겨의 경우도 배추를 제외한 작물종에서 쌀겨와 유사한 생육저해를 보였다.

This study was carried out to examine the effect of rice bran, barley bran, burned rice bran, and burned barley bran on the growth and yield of Chinese chive (Allium tuberosum Rottler), taro (Colocasia esculenta), and weed control. When the above 4 brans were examined 13, 27, 41 and 57 days respectively after application, the plant height of Chinese chive applied with burned barley bran was significantly higher than non-treated control, whereas the other brans did not have any distinct effect on the plant height or population number of Chinese chive. However, when examined 57 days after the application of the above 4 brans, all the plants applied with brans showed more than twice the improvement in shoot fresh weight compared with non-treated control. A chemical analysis of soil 57 days after the application of the above 4 brans showed that the soils were richer in available phosphate and organic matter. Shoot fresh weight of Chinese chive at 2 weeks after cutting was significantly higher in barely bran treated plot than in non-treated plot. In the case of taro, only taro plots transplanted when 10 cm tall and applied with barley bran showed an improvement in growth increment of both the underground and above parts. However, when sowed seeds after the application of the 4 brans, the yield of taro was reduced by the brans. Thus this research indicates that the effect of brans is differ based on the amount of bran application as well as crops. The effect of weed control on Echinochloa crus-galli, Digitaria clliaris, Chenopodium album, and Solanum nigrum as affected by brans was very low in pot conditions. Weed efficacy of the brans was also very low in field conditions. Growth of Chinese cabbage and garland chrysanthemum was inhibited 63% and 37% by rice bran at $4,000kg\;ha^{-1}$, respectively, but other crops such as maize, squash, cucumber, and Chinese chive were inhibited by 0-20%. These results were similar to that of barley bran except for Chinese cabbage.
