Abstract

The present study evaluated the effect of chitosan on the changes of soil chemical properties, soil microbial population, and yield of red pepper (Capsicum annuum L.) for eco-friendly agriculture in an upland field. We utilized four treatment groups, control, foliar spray, soil drench, and foliar spray + soil drench with chitosan, and analyzed these variations throughout the seven, fourteen, and twenty one days interval. The pH values, organic matter, and available phosphate in the upland soil at the harvesting stage decreased in the chitosan treatment. The populations of bacteria, actinomyces, and fungi in the upland field were increased in plots treated with chitosan. The chlorophyll content of leaves was no significant differences between the control and the chitosan treatments, while calcium content of leaves was significantly higher in the chitosan treatments than in the control. In addition, the nitrogen content of leaves was no significant differences between the foliar spray and the soil drench. The yield of red pepper was significantly higher in the control ($383kg\;10a^{-1}$) than the chitosan treatments and the yield of soil drench with chitosan reached up to 95% of control.

Chitosan이 친환경 고추재배를 위한 친환경자재로써 토양환경개선과 고추수량 등에 미치는 효과를 조사하기 위해 엽면시비, 토양관주, 두 가지를 혼합처리 하였다. 침지시간에 따른 발아율은 무처리에서 99.4%였고, chitosan 농도가 낮을수록 침지시간이 짧을수록 발아율은 높았지만 대조구보다는 낮았다. 수확기에 조사한 토양화학성분은 chitosan 처리방법에 관계없이 정식전 보다 모두 감소하였다. Chitosan 처리횟수가 증가할수록 토양중 세균과 방선균 밀도는 증가하였고, chlorophyll 함량은 대조구보다 많았다. 고추 잎의 P 함량은 차이가 없었지만, N는 14일 간격으로 엽면시비를 하거나 21일 간격으로 토양관주를 했을 때 무처리 수준과 같았고, Ca, Mg, K는 7일 간격으로 혼합처리시 높은 경향을 보였으며, 토양관주를 했을 때 생육상태는 가장 우수하였지만, 수량은 대조구에서 $383kg\;10a^{-1}$ 수준으로 가장 많았고, 토양관주 처리에서 대조구의 93.0~95.0% 수준을 보였다.
