The challenge facing scientists is to produce a high-yielding perennial plant adapted to the poor soils of the uplands, and one that is highly responsive to low amounts of purchased inputs, and that resists diseases and insect pests. Bangladesh, Cambodia, China, India, Indonesia, Myanmar, Thailand, and Vietnam are important producers. An escalating desire for food security is resulting in an increasing interest in small scale rice growing. Upland rice. In Southeast Sulawesi Province, Indonesia, upland rice has been cultivated by the traditional slash-and-burn system during the rainy season for many years2, 3, 4, 5). Adding lime to the subsoil is not practical, but in 1994 IRRI and Indonesian scientists began experiments to see if components of lime applied to the soil surface could be leached down into the subsoil. The general perception about the upland environment is that it is drought-prone, usually sloping land with erosion problems, and has … Subedi, S., U.R. Soils there have been badly eroded and degraded as a result of the slash-and-burn agriculture that for many years followed logging. Euphytica 162:395–410, Singh, Chandra Vir; Ghosh, Bidhan Chandra; Mittra, Bishwa Nath; Singh, Rama Kant.2008. The Brazilian grain yield of upland rice is ~ 2.0 Mg ha − 1, approximately 31.5% of lowland rice yield (CONAB 2017). (2000). The cultivation and The passage of the Organic Agriculture Act of 2010, otherwise known as RA 10068 signals a paradigm shift in agricultural production Studies in the Philippines have shown, for example, that hedgerows of trees, shrubs and grasses along hill contours can help reduce soil erosion up to 90 percent.

Already the new upward pressures are resulting in a movement toward permanent agriculture and intensification of land use in upland areas. Many upland farmers plant local rices that do not respond well to improved management practices—but these are well adapted to their environments and produce grains that meet local needs.. Unlike traditional paddy rice, upland rice is well suited for growing in the north's cold temperature conditions. Researchers from IRRI, Maejo University and Chiang Mai University launched a study in 1993 of the interactions between weeds, crop environmental conditions, and farmers' practices in upper northern Thailand. To make upland rice production viable, alternative approaches such as no-tillage are required. The results indicate that these technologies are now spreading in upland areas. However, in Asia, where more than 90% of the world’s rice is produced, upland rice remains an important crop for traditional smallholders1). to 13.2 million ha in 2010 (IRRI, 2013).
