Effect of Organic Materials Amendment on Growth of Jujube (Zizyphus jujuba Mill.) and Soil Chemical Properties

다국어 초록 (Multilingual Abstract)

Jujube is a deciduous broad-leaved tree belonging to the buckthorn family(Rhamnaceae) and is widelycultivated in Southeast Asia and Southeast Europe, including Korea and China and mainly consumedmedicinal herbs or dried jujube. In recent years, consumption of fresh fruits has increased, and organicorchard has also increased. The purpose of this study was to investigate soil chemical changes and growthcharacteristics of jujube when replacing the total amount of nitrogen fertilizer with organic matter in rainshelter house. In March 2017, after soil testing, bark, animal compost, rice bran, oil cake and chemicalfertilizers (NPK) were treated based on nitrogen content. After treatment of organic materials, by March 2020,the pH increased and organic matter, phosphoric acid and cation content in soil increased. After harvest ofjujube, the yield of compost treatment was the highest and the NPK treatment was the lowest. The length,hardness and weight of fruit were greater in the NPK treatment, but the diameter and sugar content were notsignificantly different from the organic material treatments except rice bran. Therefore, when the cultivationof the jujube, nitrogen fertilizer was totally replaced with organic material, there was the effect of improvingsoil chemistry, such as an increase in the organic content of the jujube orchard and an increase in the yield ofjujube but no clear effect on fruit quality.
