  • Rice is the most important staple food crop in Asia, where about 90% of the world's riceproduction is located. Rice covers 81 m ha in South and Southeast Asia, where approximately30% of the cropped land is irrigated and double-cropped throughout the year. Withthe increase in population and a continuous decline in the average farm size (0.5-2.0 ha),there is a growing need to put the existing land base to better use. The prevailing practiceof monocropping rice and then leaving the fields fallow after the harvest, could provedisastrous because of its inability to meet the increasing demand for rice and grainlegumes
