Abstract

This study was carried out to study the effect of eggplant (EG203) grafting and strawberry removal time on succeeding tomato cropping in high temperature season. In non tillage culture, bacterial wilt incidence was 30% and 0% in nongrafting and eggplant (EG203) grafting while 25% in non-grafting and 0% in eggplant (EG203) grafting in tillage culture. Commercial yield was similar in tillage and non-tillage culture using EG-203 grafting as 2,693 kg/10a and 2,657 kg/10a respectively with no difference in soluble solid content and hardness. Strawberry removal time after tomato planting enhanced plant height and internode length in 20days and 30days later removal while no difference in other growth characters. Commercial yield was higher as 1,885 kg/10a in strawberry removal before tomato planting than 1,678 kg/10a in 30days later removal. From this research, strawberry removal time should be determined by considering strawberry price and growth and expecting profit by succeeding tomato cropping.

토마토 억제 재배 시 생산비를 절감하고 토마토의 수확시기를 앞당기며 잦은 경운에 의한 토양환경을 보호하고자 가지대목(EG203)을 활용한 딸기후작 토마토 무경운 재배법 연구를 실시하였다. 가지대목(EG203)을 사용하여 토마토 재배를 실시한 결과 풋마름병 발생은 무경운 재배에서 실생은 30%, 가지대목(EG203)은 0%였으며 경운 재배에서는 실생은 25%, 가지대목(EG203)은 0%였다. 가지대목(EG203)을 이용한 경운 및 무경운 재배에서 상품수량은 각각 2,693, 2,657 kg/10a로 유사하였으며 당도 및 경도도 차이를 보이지는 않았다. 따라서 딸기 후작 토마토 재배에서 풋마름병에 대한 안전성을 높이기 위해 가지대목(EG203)을 활용하여 접목을 실시하여야하며 가지대목(EG203)을 이용하여 재배할 경우는 경운과 무경운 재배의 차이가 나타나지 않으므로 경제성 및 환경적으로 무경운 재배가 유리할 것으로 판단된다. 토마토 정식 당일, 10, 20, 30일 후 전작물인 딸기를 제거한 결과 20, 30일 후 제거에서 초장과 절간장은 길었으나 다른 생육에서는 차이를 보이지 않았다. 상품수량은 정식 당일 제거한 것이 1,885 kg/10a로 30일 후 제거 1,678 kg/10a보다 12% 많았으나 전작물인 딸기의 제거 시기는 딸기의 생육과 가격을 토마토의 기대소득과 비교 경제성을 분석하여 결정하여야 할 것으로 생각된다.
