Zinc deficiency is the most widespread micronutrient disorder in rice. It means many people who depend on rice as a staple food are effectively being starved of essential micronutrients such as iron, zinc and pro-vitamin A.. Nutritionists call it "hidden hunger." and Plant Nutrition (Japan) 19, 83–93 (1973). But most cannot in Bangladesh. Zinc (Zn) deficiency is one of the leading nutrient disorders in rice (Oryza sativa). Trierweiler, J. F. and Lindsay, W. L., EDTA-ammonium carbonate soil test for Zn. Zinc is a nutrient that plays many vital roles in your body. Forno, D. A., Asher, C. J. and Yoshida, S., Zinc deficiency in rice. How to identify. Zinc Deficiency Do S. MIKKELSON Response of rice to preplant soil application of zinc sulphate, equivalent to supplying 8 pounds of zinc per acre.Note that in the untreated area, the seedling plants failed Di%nosishhcesoils to survive. International Rice Research Institute. Zinc Deficiency (Hudda disease - Pakistan, Khaira disease - India). Those who can afford meat do not need to worry, meat has the necessary zinc required.

Aerobic rice is currently bred by crossing lowland with upland rice genotypes, for growth in an aerobic cultivation system, which is saving water and producing high yields. Zinc (Zn) deficiency is one of the leading nutrient disorders in rice (Oryza sativa). Using a chelated Zn source allows any of the Zn that does not contact rice leaves to be mobile in the soil and move downward towards the rice roots where it can also be actively taken up by the plant. and Plant Nutrition (Japan) 17, 83–87 (1971). “[So we believe that rice containing higher zinc levels] should be considered for populations that consume mostly parboiled or highly polished rice, [and also that] despite some known nutritional benefits of parboiled rice, for populations with high zinc deficiency it is prudent to promote the consumption of non-parboiled over parboiled rice.” Yoshida, S. and Tanaka, A., Zinc deficiency of the rice plant in calcareous soils. volume 42, pages537–550(1975)Cite this article. 119–146 (1967). A Zn deficient clay soil was used in our screening. “[So we believe that rice containing higher zinc levels] should be considered for populations that consume mostly parboiled or highly polished rice, [and also that] despite some known nutritional benefits of parboiled rice, for populations with high zinc deficiency it is prudent to promote the consumption of non-parboiled over parboiled rice.” Developing tissues such as meristems and reproductive organs require high zinc, but the molecular mechanisms of how zinc taken up by the roots is preferentially delivered to these tissues with low transpiration are unknown. Filipinos depend on rice as their main source of nutrition. Duffner, A. ; Hoffland, E.; Stomph, T.J.; Boonstra, A.; Bindraban, P.S. Jurinak, J. J. and Inouye, T. S., Some aspects of zinc and copper phosphate formation in aqueous systems. Soil Sci. Soils receiving high phosphorus application, Efficient photosynthesis (sugar production). Its occurrence has increased with the introduction of modern varieties, crop intensification, and increased Zn removal. J. Sci. Inadequate intakes and marginal deficiencies are common, too – in a 2000 survey of over 29,000 people in the USA, only 55% had adequate zinc intakes. Rice grains usually contain just 2-5 parts per million (ppm) of iron. Soil Sci. They don’t eat meat or supplements and stay deficient of zinc. 108, 30–37 (1969). 33, 49–54, (1969). Zinc deficiency is the most widespread micronutrient disorder in rice. Am. Bull. The lack of dietary diversity among poor communities has led to nutritional consequences, particularly micronutrient deficiencies. In China, zinc deficiency occurs on around half of the agricultural soils, affecting mainly rice and maize. Google Scholar. With ongoing deficiency the complete leaf blade turns bronze to brown. Am. Pratt, P. F., Carbonate and bicarbonate In Diagnotic Criteria for Plants and Soils (H. D. Chapman Ed., Univ. 2007a). Some plants like grains and beans contain phytate or phytic acid which binds to zinc and prevents its absorption. The International Rice Research Institute, Los Baños, Laguna, Philippines Tech. 34, 405–407 (1970). The researchers were aiming to increase that to at least 13 ppm to address iron … Enhancing the contents of iron and zinc in cereal grains will … Addition of cellulose to the soil raised bicarbonate concentrations substantially and organic acid concentrations slightly. Solution culture studies with the variety IR8 showed that with a bicarbonate concentration of only 15 mM, transport of zinc to the shoots was reduced by more than 70 per cent. 33, 356–365 (1961). Zinc deficiency is most prevalent in alkaline/calcareous, inherently low organic carbon, heavily limed, light textured, salt prone, and waterlogged soils. Calif. Div. Because zinc plays such an important role in your body, the symptoms of a deficiency can show up in a hundred ways. Chiba Agr. As depicted in figure 1, the morphological changes i.e., length of radical and plumule was shown in response to Zn NP treatment when subjected to 0 … Dark brown to reddish spots appear on the slightly chlorotic young leaf. - Precipitation of ZnS in anaerobic conditions. Zinc has been particularly missing in the rice of Bangladesh. Control Fed. It is by Donald Groth at Louisiana State University AgCenter. Zn is deficient in 50% of the world’s agricultural soils and is . Zinc nutrition also helps in mitigation of iron toxicity in rice. This article explains everything you need to know about zinc, its functions, benefits, the risk of deficiency and potential side effects. Department of Agriculture, University of Queensland, Australia, You can also search for this author in Symptoms Now the fifth leading factor in widespread disease worldwide, zinc deficiency is responsible for a rise in mortality rates in undeveloped nations due to connections to childhood diarrhea and pneumonia. Agr. Ponnamperuma, F. N., Dynamic aspects of flooded soils. Learn more about Institutional subscriptions. Background: Zinc (Zn) deficiency is one of the most widespread soil constraints affecting rice productivity, but the molecular mechanisms underlying the regulation of Zn deficiency response is still limited. Studies have suggested a simple way to overcome zinc deficiency in humans is by applications of zinc to crops like rice. International Rice Research Institute. Background Zinc (Zn) deficiency is one of the important abiotic factors limiting rice productivity worldwide and also a widespread nutritional disorder affecting human health. Takai, Y., Koyama, T. and Kamura, T., Microbial metabolism in reduction process of paddy soils I. Zinc (Zn) deficiency is the most widespread micronutrient disorder in rice (Oryza sativa), but efforts to develop cultivars with improved tolerance have been hampered by insufficient understanding of genetic factors contributing to tolerance. Zinc availibility decreases after flooding. 3, 693–699 (1971). (John Hopkins Press, Baltimore, Maryland) pp. Soc. Soc. Effects of zinc deficiency on rice growth and genetic factors contributing to tolerance. Agron. The Philippines is one of the major rice-producing and rice-consuming countries of Asia. Goss, J. Agr. Zinc availibility decreases after flooding. Zinc deficiency affects around 17% of the world’s population, mostly in developing countries. In this review the diagnosis and correction of Zn deficiency in several important crops in a wide range of soils has been discussed. However at pH 4.5 the same concentrations of acetic acid reduced uptake by more than 90 per cent. Research 19, 859–868 (1968). Plant and Soil 16, 347–360 (1962). Zinc deficiency is defined either as insufficient zinc to meet the needs of the body, or as a serum zinc level below the normal range. The same is true for zinc supplements, which are too expensive for poor people to afford. Fe and Zn deficiencies are widespread and affect millions of Filipinos across ages and social strata with health and economic consequences. The high dependence on rice and the lack of diversity in the diet have led to nutritional and health problems, particularly micronutrient deficiencies. Soviet Soil Sci. Nene, Y. L., Symptoms, cause and control of Khaira disease of paddy. Stunted, uneven growth. Incidence of the deficiency appears more closely related to zinc availability than to total zinc content of the soil, and spontaneous recoveries of affected crops are common. Severe yield losses are threatening food security, caused by abiotic stresses such as zinc deficiency, a widespread micronutrient disorder … Annual Report for 1971. Yoshida, S., Forno, D. A. and Bhadrachalam, A., Zinc deficiency of the rice plant on calcareous and neutral soils in the Philippines. Rice is one of the most important staple crops worldwide and a growing world population will lead to an increasing demand for food in the upcoming years. and Plant Nutrition 15, 75–80 (1969).

N ENE (1) was the first to show that a foliar application of zinc sulfate corrects a disorder of the rice plant long known as Khaira disease in North-Central India. Background Zinc (Zn) deficiency is one of the important abiotic factors limiting rice productivity worldwide and also a widespread nutritional disorder affecting human health. Shiratori, K., Suzuki, T. and Miyoshi, H., (On a disease of rice plant similar to “Akagare” occurring in paddy field soil dredged from Tone River.) The expression profiles of OsbZIP48 , OsbZIP49 , and OsbZIP50 in rice roots and shoots indicate that these genes are not responsive to Zn deficiency ( Fig. 9, 31–65 (1957). 1. and Plant Nutrition (Japan) 13, 25–30 (1967). Annual Report for 1970. Zinc-deficient soils constrain rice production and cause Zn-malnutrition. 64, 444–447 (1972). Our results with rice seeds reveals that Zinc nanoparticle (Zn NP) caused increase of radicle and plumule length in rice. Rice is sensitive to Zn deficiency; it is the most widespread micronutrient disorder in rice. These consequences necessitate the design and evaluation of effective programs and policies for reducing micronutrient deficiencies. In Pakistan, the most recent national nutrition survey indicated that over 40% of women are zinc deficient. A Zn deficient clay soil was used in our screening. In fact, zinc deficiency has become so serious around the world that it is responsible for 176,000 diarrhea deaths, 406,000 pneumonia deaths, and 207,000 malaria deaths. Many conditions can increase the risk of developing zinc deficiency. Zinc is an essential plant nutrient required for several biochemical processes in the rice plant, including chlorophyll production and membrane integrity. Areas with zinc deficient soils are often regions with widespread zinc deficiency in humans. 93–97 (1966). A greenhouse experiment was conducted with the objective of determining Zn requirements of lowland rice. Results of the present study indicate that transient peaks in the concentration of bicarbonate and possibly of organic acids in the soil solution following soil submergence may induce temporary zinc deficiencies. Prime Minister Narendra Modi released 17 bio-fortified varieties of eight crops this month on World Food Day, which can increase the nutritional value of food staples three-fold.. Zinc (Zn) deficiency is one of the leading nutrient disorders in rice (Oryza sativa). 53–57 (1972). Growth and zinc content of plants. Zinc deficiency of rice is widespread throughout Asia on neutral to alkaline calcareous soils which contain more than 1 percent organic matter. Proc. - Volume 97 Issue 1 - Rosalind S. Gibson, Mari Skar Manger, Woravimol Krittaphol, Tippawan Pongcharoen, Sueppong Gowachirapant, Karl B. Bailey, Pattanee Winichagoon Zinc (Zn) deficiency is the most prevalent micronutrient disorder in rice and leads to delayed development and decreased yield. Zinc deficiency is more common among older people who live in institutions and people who are homebound. Soil Sci. N ENE (1) was the first to show that a foliar application of zinc sulfate corrects a disorder of the rice plant long known as Khaira disease in North-Central India. pp. Am. The Rice Journal 72, 76–77 (1969). The identification of Zn-deficiency tolerant rice lines indicates that breeding might overcome these constraints. © 2021 Springer Nature Switzerland AG. Soil Sci.

It is therefore, imperative to apply zinc to such Zinc (Zn) is an indispensable element for rice growth. Y.) Zn deficiency resulted in a marked decrease in shoot dry matter production of most genotypes after 28 days of growth. / Eliminating zinc deficiency in rice-based systems.Washington D.C., USA : VFRC, 2014. In Pakistan, the most recent national nutrition survey indicated that over 40% of women are zinc deficient. - 104.171.4.183. Soil Sci. Zinc deficiency affects around 17% of the world’s population, mostly in developing countries. Many studies have identified Zn efficient rice genotypes, but causal mechanisms for … Zinc is a nutrient that plays many vital roles in your body. Several studies have investigated how rice plants respond to Zn deficiency and examined the differences between Zn-efficient (ZE) and Zn-inefficient (ZI) genotypes. Zn deficiency results in brown blotches and streaks 2 to 3 weeks after transplanting, as well as stunting, reduced tillering, and low productivity of rice plants. Proc. Thorne, W., Zinc deficiency and its control. - Formation of Zn-phosphates following large applications of P fertilizer. 1. Water Pollut. Hodgson, J. F., Chemistry of the micronutrient elements in soils. What is Zinc Deficiency? Zinc deficiency remarkably depressed the zinc concentrations in the meristematic tissues of rice plants.
