An Intergenerational Horticultural Program in a rural community in Korea was tried out to enhance social interaction between elderly citizens and children, to promote the positive self-esteem of the elderly in a rural community, to change the attitude of children towards the elderly, and to create a rural community full of vitality. The clients were 20 elderly (60-80 years old) and 40 preschool children (6-7 years old). The activities in this program included seed of hope, round autumn garden, dish garden, in the vegetable patch, flower decoration for the Chuseok Festival, rainbow flower basket, heart card, fragrance of love, and a kimchi party. The results were a decrease in depression among the elderly from 44.0% to 33.7%. General satisfaction among the elderly was 100%. The desire to rejoin among the elderly was 100%. General satisfaction among the children was 100%. The desire to rejoin among the children was 93.5%.

This study was performed to analyze the improvement of soil physical property and soil biota characteristics through cultivation of green manure crops for a one-year period before creation of a tea plantation as follows. The study revealed that the contents of available phosphate tended to decrease after sod-culture by green manure cultivation and open-pollination, when compared to the level before cultivation. The ratio soil porosity increased by approximately 30% when Crotalaria juncea and Sorghum bicolar L. Moench were cultivated, while the soil bacteria and fungi also increased. In a research on microfauna using a pit fall trap, the population number of the microfauna was 174 of 27 species in the plot of open-pollinated sod-culture and no organic matter application, and 268 of 26 species in the plot of Sorghum bicolar L. Moench. Consequently, the culturing tool of Crotalaria juncea recorded the highest level of species diversity at 2.5, the evenness index at 3.7 and richness at 4.6, with the lowest level of a dominance index. The ecological quotient of microfauna was 0.76 in the plot of Sorghum bicolar L. Moench, and 0.63 in the plot of Crotalaria juncea.

아열대 지역에서의 콩생육기간과 수량과의 관계를 구명하고자 1981년 대만 소재 아세아 채소연구개발센터(AVRDC)에서 선발한 콩 482계통을 봄, 여름, 가을 작기에 동일재료를 공시 생산력시험을 실시하여 얻은 결과를 요약하면 다음과 같다. 1. 작기별 평균수량 및 최고수량은 봄작기에서 높았고 가을, 여름 순으로, 낮았으며 가을 작기에서 계통간의 수량차가 제일 적었다. 2. 콩 수량은 작기에 관계없이 생육일수가 증가됨에 따라 증가되었으나 개화일수가 길어짐에 따라 수량은 감소되었다. 3. 100립중은 작기에 관계없이 결실기간이 길수록 무거운 경향을 보였으며 여름과 가을 작기에서 그 관계가 유의적이었다. 4. 다중회귀분석 결과 봄, 여름, 가을 어느 작기에서나 개화일수는 짧고 결실기간이 상대적으로 긴 계통이 고위생산력을 보이는 계통으로 고려되었다.
