Participatory Crop Improvement: Effect of Farmers’ Selection Criteria on Diversity of Rice Grown In Uplands of Nepal. Site selection Bearing in mind the Upland rice water requirement (800-900 mm/annum, evenly distributed over the production season) it is important that supplementary irrigation of some sort is available. The land with soft-top black soil with more than 2 cm is preferable. This, in turn, destroys the watershed, producing problems in the lands below. 26 … startxref %PDF-1.4 %���� Scientists from the International Rice Research Institute (IRRI) have been working with colleagues in the Upland Rice Research Consortium to better understand pathogen populations and to identify resistance genes found in some cultivars. It is the key crop in agricultural land use. 2001. So the risk from blast increases as cropping practices intensify and improved varieties are introduced. -Brillengineering.com. Tropics. A rice plant that would not have to be planted annually could help reduce erosion by providing a permanent ground cover. labour efficiency, upland farmers extended the field size and produced a large volume of upland rice far exceeding consumption demand. Armed with this knowledge, they are working with IRRI's upland rice breeder to combine such genes with other desirable traits for incorporation into new upland varieties. But more improvements are needed to meet the new challenges. Dhakal, H.B. The passage of the Organic Agriculture Act of 2010, otherwise known as RA 10068 signals a paradigm shift in agricultural production 0000024764 00000 n Use a heat mat to keep rice seeds warm. Upland rice is rice grown on dry soil rather than flooded rice paddies. 2006. One modern upland rice varieties that yields 2.9 tons per hectare (t/ha) on the average and matures in just 119 days is PSB Rc9 (Apo). Such legumes can simultaneously increase farmers' incomes and contribute to sustainability of the farming system. The extent of swidden agriculture and the dependence on labour-saving practices were higher in the farmer group with So it is also important to select an area with adequate rain-fall throughout the year. Journal of plant nutrition and soil science. Upland rice is known as a new source of grain in the twenty‐first century, which is one of the potential crops to ensure the world's food security and feed human beings (Conway & Toenniessen, 1999). Almost two-thirds of the upland rice area is in Asia. [3] Some have outyielded traditional rices by more than 100 percent in evaluations. Population growth, the demands of urbanism and industry, and the increasing adoption of high value cash crop farming in the surrounding lowlands are leading to strong competition for upland terrain. 171, no. Ghimire. These results suggest that CA has the potential to improve soil productivity of upland rice production in Laos, but that the effect of CA application is highly dependent on … Upland rice is grown in rainfed fields prepared and seeded when dry, much like wheat or maize. The results indicate that these technologies are now spreading in upland areas. Subedi, S., U.R. 0000002939 00000 n Their suspicions arose from the fact that many highly weathered upland soils are inherently low in phosphorus and are acidic. In one project on phosphorus management, they are investigating how weed communities change as soil fertility is improved over time in the Philippines, Indonesia, and Thailand. vol. Bergreis AGRICULTURE. 0000003494 00000 n Characterization of drought stress environments for upland rice and maize in central Brazil.

An analysis of the patterns of technology adoption by upland rice farmers in southern Yunnan and of the impact of technologies was conducted using farm–household data collected during 2005. The acidity present in the subsoil of many upland areas prevents plant roots from reaching the moisture and nutrients therein, thus reducing crop yield. Soils there have been badly eroded and degraded as a result of the slash-and-burn agriculture that for many years followed logging. The ecosystem is extremely diverse, including fields that are level, gently rolling or steep, at altitudes up to 2,000 metres and with rainfall ranging from 1,000 to 4,500 mm annually.

It is a challenge IRRI scientists are currently working on. Most weed species also are victims of their own diseases. There exists, however, a widening gap between its regional demand and supply. The goals are to understand the diversity of farmers' practices and decisionmaking processes and to grade the factors that limit rice crop yields. (2006).Field Crops Res 97:43–52, Fisher AJ, Ramırez HV, Gibson KD and Da Silveira Pinheiro B,(2001). 0000066564 00000 n Unfortunately, these farmers do not have a ready source of information on upland rice production. The crop thrives where there is ample rain. rice production are closely analyzed and discussed. This article outlines some of the management practices being studied for sustainable rice production systems. 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.[2]. From the earlier releases of three upland rice varieties in Uganda in 2002 courtesy of the Rock feller support farmers were able to reap $9 million (14.9 billion) in 2005.
