To develop the agriculture productivity potential in the tropical and subtropical regions in relation to world's population of the future is very important. Total world's population in 2110 will reach 10.5 billion and the 95% of the population expansion will occur in previously asserted regions. The inappropriateness area for agriculture production will have mostly high population increase, and the highest rate of population increase will be in Africa. Where the population supporting capacity will be a critical situation are Central America, Southwest Asia and Africa by 2000, and these 3 regions would face in difficult situation, although it would be taken increasing level of material inputs to produce better yield. For improvement of the rate of self-supplied food in tropical and subtropical developing countries, it should be taken several scheme, namely, the accelerated development of irrigation, the expanding of cultivation acreage, high productivity level per unit area, soil conservation measures, etc. Finally, it seems that an exhaustive study on the tropical and subtropical agriculture and the appropriate agrotechnology are highly significant to feed it's population from it's own lands, and at the same time it would need resolute capital investment and technology from developed countries.

The duck-rice forming system is increasingly spread up throughout Korea since 1992. It is discussed the rice field, rice quality, weed and pest management in the duck-rice weeding system compared to conventional farming system. Moreover the optimizing duck population, system management and fertilizer application rate were reported. Energy input and output by duck-rice farming system were carefully compared with those of low input sustainable paddy field and conventional farming paddy field. To find out the environmentally sound function of duck-rice system, the total nitrogen in paddy soil and paddy water, and nitrogen cycle in paddy rice cultivation system were analysed. finally the input and output were calculated, and ecological characteristic were determined in terms of nitrogen balance, labor input, animal input, renewable energy input, turnover of soil organic matter, energy loss, non-renewable indirect and direct energy input. It was concluded duck-rice weeding system could be recommended in terms of net only environmentally sound, but also farmer's income. But there are still some research needs for successful adaption of duck-rice farming to investigate to determine the optimal population of duck in rice paddy field unit, release time of duckling, duck management after release, and strategy for duck marketing and duck processing.

국제화 시대에 우리는 여러 측면에서 미증유의 많은 대내외적 어려움에 직면하고 있다. 이러한 시대적 상황하에서 우리는 새로운 세기의 열대농업에 대한 인식을 재정립함으로써 민족번영의 활로를 열어야겠다. 열대농업 제분야에 대한 국가적인 관심과 노력 그리고 사업추진은 국력의 신장, 수출시장의 개척, 식량 및 원자재의 안정적 확보, 민족의 세력권 확대, 개발도상국 식량문제 해결 및 세계 평화와 공존에 기여할 수 있는 가능성을 제공할 수 있을 것이기 때문이다.

In oder to evaluate the effects of functional composts which include elvan, jade and loess, the growth and the yield of Chinese Cabbage and its content of sugar, nitrate and vitamin C were analysed. This study was conducted in lysimeter which was installed in the Experimental Farm of Dankook University. Total fresh weights of Chinese Cabbage were higher in the treatments of compost with mixture of elvan, jade and loess, while numbers of leaf was not increased in those treatments compared to control plot. Leaf length increased more than leaf width, specially in the plot of evlan treatment. Fresh weight of leaf blade and midrib in outer leaf was highest in the plot of elvan treatment among the 6 treatments. Sugar content in the Chinese Cabbage showed lower in the treatment of compost with mixture of elvan, jade and loess compared to control plot. Vitamin content in midrib was high in the treatment of compost with mixture of elvan, jade and loess compared to control plot. Vitamin content was high in leaf blade compare to those in midrib, and it showed highest value in the treatment of compost with mixture of jade. Nitrate concentration of leaf blade and midrib in the treatment of compost with mixture of loess was lowest at 2,021ppm and 2,235ppm respectively. It shows the effective function of mixture compost with jade, loess and elvan to decrease nitrate content in the Chinese Cabbage.
