Irrigated paddy rice (Oryza sativa L.) is a staple food for roughly half of the world’s population. Concerns over water quality have arisen in recent decades, particularly in China, which is the largest rice-producing country in the world and has the most intensive use of nutrients and water in rice production. On the one hand, the poor water quality has constrained the use of water for Cited by: 3. Irrigation is the application of controlled amounts of water to plants at needed intervals. Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall. Irrigation also has other uses in crop production, including frost protection, suppressing weed growth in grain fields and preventing soil.

Around − mm is a typical amount of water needed for irrigated rice in Asia. Irrigated rice receives an estimated 34−43% of the total world’s irrigation water, or about 24−30% of the entire world’s developed fresh water resources. Irrigating rice with mechanized systems is a recent and exciting evolution in irrigated agriculture. By combining modern agricultural technologies like Nelson Series Pivot Products, Pressure Regulators, and Series Control Valves to replace traditional flood irrigation methods, rice producers are now successfully irrigating rice on ground that is sloped as well as flat; . Rice is grown in lowland paddies, which is flood irrigated. In the most undulating areas, continuous flooding is difficult and some farmers seek alternative irrigation methods. Grain yield in sprinkler irrigated rice ranges between 80 and % of that obtained under flooding, but for this, fertilizer and water should be properly managed. For sprinkler irrigated rice, fertilizer should be Author: José Maria Barbat Parfitt, Germani Concenço, Walkyria BuenoScivittaro, André Andres, Jaqueline Tromb. As a result of the green revolution, the use of yield-increasing inputs such as fer tilizer and pesticides became a matter of course in irrigated rice farming in Southeast Asia. Pesticides were applied liberally, both as a guarantee against crop failure and as a means of fully utilizing theBrand: Springer-Verlag Berlin Heidelberg.

Credit to the Portuguese for bringing rice and irrigated culture to West Africa persisted without question well into the twentieth century despite the fact that accounts of Portuguese introduction of the crop to West Africa seldom addressed how mariners might have transferred knowledge of irrigated rice to : Harvard.

This book summarizes research conducted from to to develop a new concept and the tools needed for site-specific nutrient management (SSNM) in irrigated rice systems and the tools needed for applying it in farmers’ fields.
