시설 토마토 과실의 상품성을 향상시키기 위하여 칼륨 엽면처리 농도 및 시기를 분석한 결과, 0.5% 칼륨 엽면처리구에서 과중이 200~400g인 상품과 비율이 75.5%로 대조구에 비해 29.5%증가하였다. 처리시기는 착과기가 가장 좋았는데, 착과기에 0.5% 칼륨를 엽면처리하면 상품과 비율이 대조구에 비해 5.9% 증가하였고 상품수량은 10% 증가하였다.
This study was performed to determine the optimum concentration of potassium for the foliar application, and its application stage to increase the production of marketable sized tomato. For this purpose, 0.25, 0.5 and 1.0 percent of potassium phosphate (KH2PO4) were applied in the leaves of tomatoes by the stage of flowering, fruit setting and fruit development. The control plants were applied with distilled water. The results showed that foliar application with 0.5 percent of potassium phosphate increased the proportion of medium sized fruit of the products by 29.5 percent compared to the controlled plants, which is highest in the treatments. The foliar application of 0.5 percent of potassium phosphate at the fruit setting stage increased the yield of marketable sized fruit by 5.9 percent compared to the controlled plants.
