가지는 최근에 경남, 전북 등의 지역에서 수출계약 재배면적이 증가하면서 농업인의 관심이 높아지고 있는 작물이지만 국내에서는 지금가지 주요작물로 취급되지 않아 연구가 부족한 실정이다.
수출 대상국과의 경쟁력을 높이기 위해서는 수출용으로 재배되는 주요 품종이나 작형에 맞는 생산기술의 개발이 시급히 요구되고 있다.

For improvement of marketable fruit rate and productivity and labor saving in exporting eggplant, experiments were conducted on the effects of different methods of main stem training, main stem leaf thinning, and lateral leaf thinning in long-tenn culture system.
The results are summarized as follows; U shape training showed higher marketable fruit yield and fruit number compared to Y shape training, although the number of harvested fruit was lower. In the U shape training, training in 45° showed higher flower number compared to those of 60° and 30° training.
In comparison of labor input between the two training methods, general management labor input such as spray of fruit set chemical, thinning, and hat vest was 19 hr/10a in U shape training, which was equivalent to 16% saving compared to 22.4 hr/10a in Y shape training. And the working condition was more convenient in U shape training than in Y shape training.
The 45° U shape training showed better quality than in Y shape training, but there was no difference in the total yield. In the 45° U shape training, there was less difference in light transmission in the eggplant canopy compared to that of Y shape training.
Among the different timing of main stem leaf thinning, there was no difference in marketable fruit number. But the rate was affected by lateral leaf numbers and the treatment of leaving 2 leaves showed the highest fruit number. Length of harvest days were different in seasons. The lengths were 30∼40 days in December to February and 20-25 days in March to May. By the training angle, days to harvesting were shortened by 1∼2 days in 30° training, but there was no effect by thinning methods.
Leaf area index was lower in the treatment of earlier thinning and lower number of the lateral leaf. Fruit drop rate was higher in the thinning leaving 2 lateral leaves than in leaving 3 leaves. The earlier thinning showed higher yield but the number and rate of the marketable fruit were lower when the soil moisture was sufficient.
In conclusion, 45° U shape training method was the best in long-term culture of· eggplant. The marketable ft uit rate· was· the highest when thinning was done in fruit enlargement period of 5∼7 days ahead of harvest in the· stem. Lateral stem thinning leaving 3 leaves was good for yield increase, but there was no difference among the thinning methods affected by watering amounts.
