The acidity present in the subsoil of many upland areas prevents plant roots from reaching the moisture and nutrients therein, thus reducing crop yield. Researchers produced cultivars adapted to poor soils, and with improved blast resistance and drought tolerance. Upland rice was popularized in Uganda over 10 years ago by then Vice President Prof. Gilbert Bukenya. Rotations of rice and legumes could lead to stable, higher value production, they concluded. trailer 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. 0000002570 00000 n 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. It is a challenge IRRI scientists are currently working on. 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.

Rosyara, H.B. to 13.2 million ha in 2010 (IRRI, 2013). The land with soft-top black soil with more than 2 cm is preferable. An escalating desire for food security is resulting in an increasing interest in small scale rice growing. These species, however, can be crossed with cultivated rice. Dhakal, H.B. Tropics. Already the new upward pressures are resulting in a movement toward permanent agriculture and intensification of land use in upland areas. Adhikari, B.R. It does not require flooding during its lifecycle. 0000006599 00000 n International Rice Research Institute, Makati City, Philippines, p. 35 (2000). �@�Ld@�#�P��T����N��]$��=�Mf�=�|��ι ��ct�� p�� p4�l����l= r�e:p�h`1��;�]��!�aK�3�����;E��ч 5t��/�=�1�����Ĭ�գ��ҹ����ሦ�|�]�%u��M�Gw�;V�er|2�]��_N�*�]a�Ӝ�nK. Upland rice is grown in rainfed, naturally well-drained soils with bunded or unbunded fields without surface water accumulation. On the other hand, upland rice in Southeast Sulawesi Province One approach is to search for rice plant species that exhibit a characteristic known as allelopathy. Consortium scientists are also trying to understand how upland rice farmers' cropping systems contribute to soil erosion, with the aim of proposing possible erosion control techniques. This would be done by manipulating soil chemistry and using deep-rooted, acid-tolerant rice cultivars to help capture the leached components. 2001.

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]. 0000040701 00000 n Journal of plant nutrition and soil science. Although the rice technology of the 1960s and 70s focused on irrigated rice, farmers in the uplands were not forgotten. Research on farms in Thailand, Laos and the Philippines has confirmed what scientists had long suspected: that a lack of phosphorus in upland farms is limiting rice crop yields. 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). RICE. xxxx. 0000066564 00000 n But the scientists found that the lack of phosphorus will limit production even if calcium is added to the soil to overcome the acidity, or if acid-tolerant cultivars are planted. To make upland rice production viable, alternative approaches such as no-tillage are required. It is the key crop in agricultural land use. Arraudeau, M. A. Upland rice: Challenges and opportunities in a less favorable ecosystem. 287 0 obj<>stream This study identified the determinants of productivity and technical efficiency (TE) of upland rice in Sarangani Province, Philippines. 259 29 0000015110 00000 n 2006. Participatory Crop Improvement: Effect of Farmers’ Selection Criteria on Diversity of Rice Grown In Uplands of Nepal. Almost two-thirds of the upland rice area is in Asia. 0000068871 00000 n Vol (under review), Subedi, S., U.R. Tropical regions Upland regions Rice Production. -Brillengineering.com. rufipogon F1, F4, and BC1F4 Progeny. [ 1 ] Upland rice is grown in rainfed fields prepared and seeded when dry, much like wheat or maize. Upland zones are found in Asia 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. Scientists at national agricultural research systems have crossed these improved rices with local cultivars and farmers are now beginning to grow the progeny. 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. 0000003494 00000 n 0000011820 00000 n Transplant at the same time you would your tomatoes and peppers – after the last frost in … D.D. 0000031598 00000 n 2. 0000014087 00000 n 0000025500 00000 n Pandey S., Behura D.D., Vilano R. and Naik D. Economic cost of drought and farmers’ coping mechanisms: a study of rainfed rice systems in Eastern India, in Discussion Paper Series. 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. 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. The crop thrives where there is ample rain. The goals are to understand the diversity of farmers' practices and decisionmaking processes and to grade the factors that limit rice crop yields. Upland rice production accounts for 20% of the total rice produced in Nigeria. Gurung, S. Pandey.xxxx. %%EOF 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. Nearly 100 million people now depend on upland rice as their daily staple food. Almost two-thirds of the upland rice area is in Asia. Bangladesh, Cambodia, China, Northeastern India, Indonesia, Myanmar, Thailand, Nepal, and Vietnam are important producers. Since the introduction of upland rice in 2002, rice farming has grown from 4,000 farmers to over 35,000. Tropical regions -- Upland regions -- Rice -- Production teelt Rice Their suspicions arose from the fact that many highly weathered upland soils are inherently low in phosphorus and are acidic.

Production is variable because of the lack of technology used in rice production. Bangladesh J. Agril. Scientists in the Philippines tested the competitiveness of a dozen cultivars against weeds to help farmers choose the most highly competitive one. 0000069003 00000 n Adhikari, B.R. Ojha, D.P. Almost two-thirds of the upland rice area is in Asia. 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. Although many traditional upland cultivars show stable resistance to this disease under low-input cropping practices, they have other characteristics that make them difficult to use in intensified systems.
