Bihar and western Uttar Pradesh region in India. In <strong>the</strong>se conditions, <strong>the</strong> productivity <strong>of</strong> winter<br />
maize is around 5-7 t/ha, with less water requirement and relatively shorter duration than <strong>the</strong><br />
wheat crop. Also in <strong>the</strong> Diara lands, experiencing floods during <strong>the</strong> rainy season, maize is<br />
becoming a successful crop on receding moisture during <strong>the</strong> winter season.<br />
5. In nor<strong>the</strong>rn Vietnam, almost 80,000 ha are presently grown under maize in <strong>the</strong> winter season<br />
along <strong>the</strong> Red River after two crops <strong>of</strong> rice. This has become possible mainly due to <strong>the</strong> adoption<br />
<strong>of</strong> transplanted maize technology. Earlier, no such possibilities existed <strong>of</strong> raising a third crop<br />
in <strong>the</strong> traditional rice-rice system in North Vietnam. Transplanting <strong>of</strong> maize also helps in<br />
reducing <strong>the</strong> growth period <strong>of</strong> <strong>the</strong> crop, thus enabling it to fit into a rice-rice-maize system<br />
successfully. Very high yield levels <strong>of</strong> 6-9 t/ha are realized through this practice.<br />
6. Winter maize is also becoming a successful crop in nor<strong>the</strong>rn Philippines and relatively<br />
cooler regions <strong>of</strong> Punjab in India and tarai <strong>of</strong> Nepal.<br />
7. These developments clearly reveal future "possibilities <strong>of</strong> increasing both additional area<br />
under maize and <strong>the</strong> productivity in <strong>the</strong> region. These experiences will have to be translated<br />
into practice in similar areas in o<strong>the</strong>r countries where such a potential exists. No doubt, more<br />
Research and Development (R & D) efforts supported by appropriate policies would be necessary.<br />
Also, such a technology would require intensive agricultural practices and higher inputs,<br />
appropriately supported by market and pricing policies, as well as demand <strong>of</strong> maize for <strong>the</strong><br />
processing industry.<br />
8. Ano<strong>the</strong>r interesting development is <strong>the</strong> cultivation <strong>of</strong> maize for vegetable purposes as "baby<br />
corn" in Thailand.<br />

9. As reflected earlier, <strong>the</strong> Asia-Pacific region has shown remarkable progress towards<br />
increases in both <strong>the</strong> production and productiVity <strong>of</strong> maize. Yet, <strong>of</strong> <strong>the</strong> 24 maize producing<br />
countries, 15 <strong>of</strong> <strong>the</strong>m still produce
