Abstract

Potassium (K) is an element essential for plant growth. This study was aimed to examine the effects of three formulations of potash feldspar, powder, sand, and granule type on the growth of radish and beet in organic farming. 0.1% three formulations of potash feldspar were treated on the soil before transplanting 15 days-old seedlings of radish and beet in greenhouse. The results showed that all kinds of potash feldspar significantly increased shoot and root growth, and soluble solid contents excepted for root hardness in radish and beet. Among them, the powder type of potash feldspar was the most effective on foliage and root growth of radish and beet. Based on the results, it was confirmed that 0.1% potash feldspar treated in the rhizosphere of radish and beet can promote the growth of them.

칼륨(K)은 식물의 생육에 필요한 기본 요소 중의 하나이다. 본 연구는 분상, 입상, 사상의 카리장석 제형별로 유기농 무와 비트의 생육에 미치는 영향을 구명하고자 수행하였다. 시설하우스에서 15일 육묘한 무와 비트 묘를 정식하기 전에 3종의 0.1% 카리장석을 토양에 혼화 처리하였다. 처리한 모든 종류의 카리장석은 무와 비트의 뿌리 경도를 제외하고 무처리에 비해 유의적으로 무와 비트의 뿌리, 줄기생육 및 당도를 향상시켰다. 특히, 분상 카리장석이 가장 효과적으로 무와 비트의 생육을 촉진하였다. 농가에서 유기농 비트와 무의 근권에 카리장석을 시용할 경우 지상부와 지하부의 생육을 촉진할 수 있을 것으로 판단한다.
