upland rice production

Those involved find themselves faced—in addition to the usual upland problems—with an urgent need to conserve the soil and the diversity of plant species, and to cope with increasingly frequent and severe weed and disease infestations. To make upland rice production viable, alternative approaches such as no-tillage are required. 2008. Review: Breeding upland rice for drought resistance. by Fisher T, Turner N, Angus J, McIntyre L, Robertson M, Borrell A, et al., Brisbane, Australia (2004). 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. The acidity present in the subsoil of many upland areas prevents plant roots from reaching the moisture and nutrients therein, thus reducing crop yield. 0000034694 00000 n 0000006599 00000 n Competitiveness of semidwarf upland rice cultivars against palisadegrass (. The yield results from all five treatments shows startling discrepancy from the provincial and even national average in rainfed upland rice production that ranging only from 1.5 to 2 tons per hectare. rice production are closely analyzed and discussed. Courtois B., McLaren G., Sinha P.K., Prasad K., Yadav R. and Shen L. Mapping QTL associated with drought avoidance in upland rice. 2007. Euphytica 162:395–410, Singh, Chandra Vir; Ghosh, Bidhan Chandra; Mittra, Bishwa Nath; Singh, Rama Kant.2008. 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. Recently, scientists have been improving their knowledge of the genetics of resistance to the blast fungus, one of the most damaging diseases of rice, and are using the techniques of biotechnology to develop cultivars with more durable disease resistance. 0000015110 00000 n 0000002760 00000 n Arraudeau, M. A. Upland rice: Challenges and opportunities in a less favorable ecosystem. These species, however, can be crossed with cultivated rice. These varieties thrive in southeast Michigan. 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. 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. Upland rice is grown in rainfed fields prepared and seeded when dry, much like wheat or maize. Kondo M, Pablico PP, Aragones DV, Agbisit R, Abe J, Morita S, et al., Genotypic and environmental variations in root morphology in rice genotypes under upland field conditions. The results indicate that these technologies are now spreading in upland areas. Bangladesh, Cambodia, China, Northeastern India, Indonesia, Myanmar, Thailand, Nepal, and Vietnam are important producers. Seeds germinate in about one week. Production is variable because of the lack of technology used in rice production. PSB Rc11 (Canlaon), on the other hand, yields 2.6 t/ha on the average and matures in 125 days. Rosyara, H.B. At present they are studying the processes that govern the rate of leaching of lime components and their accumulation in the subsoil. Atlin GN, Laza M, Amante M and Lafitte HR, Agronomic performances of tropical aerobic, irrigated, and traditional upland rice varieties in three hydrological environments at IRRI, in New Directions for a Diverse Planet: Proceedings of the 4th International Crop Science Congress, ed. The experiments began at the Upland Rice Research Consortium site at Sitiung, Indonesia. Upland ecosystem is prominent in most of the Indian states, covering about 13.5 per cent of the area under rice and contribute to 4 per cent of rice production. Upland rice production accounts for 20% of the total rice produced in Nigeria. Bangladesh, Cambodia, China, Northeastern India, Indonesia, Myanmar, Thailand, Nepal, and Vietnam are important producers.[1]. Upland rice is rice grown on dry soil rather than flooded rice paddies.

Another impressive result in this study was that maintaining one plant per hill induced profuse tillering. Influence of nitrogen and weed management on the productivity of upland rice. Field Crops Res 97:34–42, Alexandre Bryan Heinemann Æ Michael Dingkuhn Æ Delphine Luquet Æ Jean Claude Combres Æ Scott Chapman. 0000003494 00000 n Upland rice production has great potential as a water-saving form of agriculture if yield can be increased and stabilized across a range of environments with different levels of water supply. Soils range from highly fertile to highly weathered, infertile and acidic, but only 15 percent of total upland rice grows where soils are fertile and the growing season is long. IRRI scientists are pursuing projects on managing weeds with less herbicide use. The cultivation and Upland rice was popularized in Uganda over 10 years ago by then Vice President Prof. Gilbert Bukenya. PSB Rc9 has intermediate resistance to blast and bacterial leaf blight (BLB) but is susceptible to tungro. Dhakal, H.B. Purposeful application of the agents of such diseases to weed pests among rice crops could constitute another approach to weed control. Upland rice is grown in rainfed, naturally well-drained soils with bunded or unbunded fields without surface water accumulation. Res. Nearly 100 million people now depend on upland rice as their daily staple food. Upland rice. This page was last edited on 27 October 2020, at 20:23. 0000064723 00000 n Most of the upland rice produced in Brazil is on Oxisols with low water-holding capacity and often with low fertility. The goals are to understand the diversity of farmers' practices and decisionmaking processes and to grade the factors that limit rice crop yields. The methods are applicable to dryland rice production and are being adapted to production of wheat and some vegetables. (under review), Pinheiro B da S, Castro E da M de, Guimara˜es CM (2006)Sustainability and profitability of aerobic rice production in Brazil. The uplands have traditionally suffered from drought and infertile soils, weeds and plant diseases. L-BIRD/SANFEC. Researchers produced cultivars adapted to poor soils, and with improved blast resistance and drought tolerance. New biotechnology tools will be used to transfer the perennial characters into cultivated rice, and new knowledge of genetic diversity will be applied to develop pest resistance.[4]. Growing lowland rice: a production handbook – Africa Rice Center (WARDA) 1 Contents Preface 2 Introduction 3 Thericeplant 4 Share of rainfed/irrigated lowland rice areas in Nigeria 5 Major lowland production 2008. Such legumes can simultaneously increase farmers' incomes and contribute to sustainability of the farming system. Gurung, and S. Pandey. An escalating desire for food security is resulting in an increasing interest in small scale rice growing. Although this upland rice/S. Weeds are the most serious biological constraint to upland rice production. 0000068236 00000 n 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). 0000066564 00000 n Rice is one of the most important crops for food security in sub-Saharan Africa (SSA). 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. In 2012, MAFF reported the 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 … Ghimire. Riceplant cultivars differ in their ability to compete with weeds in the field. Their suspicions arose from the fact that many highly weathered upland soils are inherently low in phosphorus and are acidic. D.D. Molecular Breeding, 2000, Boonjung H and Fukai S, Effects of soil water deficit at different growth stages on rice growth and yield under upland conditions.

Ratanakiri Province, well-known for highland rice producing in Cambodia, has about 30,000 ha potential for upland rice production. D.D. Katmandu / Dhaka, Adhikari, B. Gurung, S. Pandey. If an allelopathic rice—or other plant species—could be found that could inhibit the growth of weeds important in rice production, it might be possible through genetic engineering to develop rice cultivars that would provide their own weed control. (2000). %PDF-1.4 %���� Ghimire. nigrum system with AMF inoculation did not guarantee rice production, it guaranteed food security and increased biomass of the neighbouring S. nigrum. Allelopathic plants can affect the growth of nearby plants through the production of biological compounds they release into the environment. Although the rice technology of the 1960s and 70s focused on irrigated rice, farmers in the uplands were not forgotten. But first it is necessary to ensure by adding phosphorus that soil quality does not degrade over time. Participatory Crop Improvement: Effect of Farmers’ Selection Criteria on Diversity of Rice Grown In Uplands of Nepal. Atlin GN, Lafitte HR, Tao D, Laza M, Amante M and Courtois B, Developing rice cultivars for high-fertility upland systems in the Asian tropics. xref to 13.2 million ha in 2010 (IRRI, 2013). 0000024293 00000 n 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. 0000068508 00000 n The Brazilian grain yield of upland rice is ~ 2.0 Mg ha − 1, approximately 31.5% of lowland rice yield (CONAB 2017). For this purpose, we propose a three-step For this purpose, we propose a three-step linked procedure: (1) a risk … Tropical regions -- Upland regions -- Rice -- Production teelt Rice Agric Water Manage 80:176–196 (2006).

Sangcupan 1 1 Research and Development Office, Cotabato Foundation College of Science and Technology … Scientists at national agricultural research systems have crossed these improved rices with local cultivars and farmers are now beginning to grow the progeny. 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. Adhikari, U.R. trailer 0000028387 00000 n Besides, the land-use efficiency of intercropping was higher than that of sole cropping of upland rice or S. nigrum , as the LER of the intercropping system with and without AMF were much greater than 1.0 (2.28 and … Diversity of upland rice can be maintained while at the same time levels of production can be increased using participatory techniques. 0000031598 00000 n labour efficiency, upland farmers extended the field size and produced a large volume of upland rice far exceeding consumption demand. The development of the upland rice ecosystem offers an Jerome Bernier, Gary N Atlin, Rachid Serraj, Arvind Kumar and Dean Spaner. Singh, B.N. By planting this cultivar and enhancing its competitive ability through good management practices, farmers should be able to reduce the number of handweedings necessary while achieving maximum yields. Leguminous plants in hedgerows make substantial amounts of atmospheric nitrogen available to both riceplants and annual crops and recycle other nutrients and organic matter. 2001. [ 1 ] Upland rice is grown in rainfed fields prepared and seeded when dry, much like wheat or maize. Bergreis AGRICULTURE. 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. 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. Scientists in the Philippines tested the competitiveness of a dozen cultivars against weeds to help farmers choose the most highly competitive one. Upland rice production accounts for 20% of the total rice produced inNigeria.WiththedevelopmentofNewRiceforAfrica(NERICA)for upland production systems, a number of farmers have shown interest in growing upland rice. 43:120–128, upland rice as important drought tolerance resource, IAAS Cereal Crop Research Bulletin – 02-2008: Rice genotypes for drought stressed uplands of Nepal, https://en.wikipedia.org/w/index.php?title=Upland_rice&oldid=985762472, Wikipedia articles with style issues from July 2017, Articles lacking in-text citations from April 2013, Articles with multiple maintenance issues, Creative Commons Attribution-ShareAlike License.

They plan then to construct mathematical models that will be used to develop practical technologies and to indicate under what conditions the technologies might be effective. Site that contains description of and instructions for building a hand-powered table top or bicycle-powered rice de-huller. However, in Asia, where more than 90% of the world’s rice is produced, upland rice remains an important crop for traditional smallholders1). Most weed species also are victims of their own diseases. xxxx. International Rice Research Institute, Makati City, Philippines, p. 35 (2000). Upland rice is being partially replaced by other crops such as maize on one hand, on the other hand the land-races are gradually disappearing from farmers' fields. 0000024764 00000 n Managing rice landscapes in marginal uplands for household food security and environmental protection- IAAS / IRRI collaborative project (Nepal Component).

Upland rice, also known as dryland rice, needs warm temperatures to germinate. 0000025152 00000 n In the uplands, blast is particularly important because the environment favors its proliferation. 0000038031 00000 n <]>> Unlike traditional paddy rice, upland rice is well suited for growing in the north's cold temperature conditions. On the other hand, upland rice in Southeast Sulawesi Province A rice plant that would not have to be planted annually could help reduce erosion by providing a permanent ground cover. Rice plays a dominant role in crop production for upland areas in the Philippines. 259 29 Upland rice is grown in rainfed fields prepared and seeded when dry, much like wheat or maize. Rana and A. Subedi. (2006).Field Crops Res 97:43–52, Fisher AJ, Ramırez HV, Gibson KD and Da Silveira Pinheiro B,(2001). Rice or other crops are planted between these strips of permanent ground cover. New challenges are emerging in the world's upland rice farming areas, where already some of the world's poorest farmers try to wrest a living from fragile soils that are fast being degraded. vol. 0000040701 00000 n Upland zones are found in Asia The crop thrives where there is ample rain. The land with soft-top black soil with more than 2 cm is preferable. IRRI scientists are also studying how fertilizer and cultural practices influence weed communities. 287 0 obj<>stream 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). Farmer and Researcher contributions to the selection of Landraces of Ghaiya (Upland rice) for Tar areas of Nepal. Pages 15-16. Bangladesh, Cambodia, China, India, Indonesia, Myanmar, Thailand, and Vietnam are important producers. However, upland rice production accounted for less than 5% of the total rice production in the 2000s (Panuju et al., 2013). So it is also important to select an area with adequate rain-fall throughout the year. 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. Upland rice So the risk from blast increases as cropping practices intensify and improved varieties are introduced. French collaborators from l'Institut francais de recherche scientifique pour le developpement en cooperation are planning similar experiments in Thailand and Vietnam. RICE.
