Bihar and western Uttar Pradesh region in India. In these conditions, the productivity of winter maize is around 5-7 t/ha, with less water requirement and relatively shorter duration than the wheat crop. Also in the Diara lands, experiencing floods during the rainy season, maize is becoming a successful crop on receding moisture during the winter season. 5. In northern Vietnam, almost 80,000 ha are presently grown under maize in the winter season along the Red River after two crops of rice. This has become possible mainly due to the adoption of transplanted maize technology. Earlier, no such possibilities existed of raising a third crop in the traditional rice-rice system in North Vietnam. Transplanting of maize also helps in reducing the growth period of the crop, thus enabling it to fit into a rice-rice-maize system successfully. Very high yield levels of 6-9 t/ha are realized through this practice. 6. Winter maize is also becoming a successful crop in northern Philippines and relatively cooler regions of Punjab in India and tarai of Nepal. 7. These developments clearly reveal future "possibilities of increasing both additional area under maize and the productivity in the region. These experiences will have to be translated into practice in similar areas in other countries where such a potential exists. No doubt, more Research and Development (R & D) efforts supported by appropriate policies would be necessary. Also, such a technology would require intensive agricultural practices and higher inputs, appropriately supported by market and pricing policies, as well as demand of maize for the processing industry. 8. Another interesting development is the cultivation of maize for vegetable purposes as "baby corn" in Thailand. IV. EXISTUG OONSTRAINTS 9. As reflected earlier, the Asia-Pacific region has shown remarkable progress towards increases in both the production and productiVity of maize. Yet, of the 24 maize producing countries, 15 of them still produce
