Download or read book Rice Production Worldwide written by Bhagirath S. Chauhan and published by Springer. This book was released on 2017-02-16 with total page 563 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses aspects of rice production in rice-growing areas of the world including origin, history, role in global food security, cropping systems, management practices, production systems, cultivars, as well as fertilizer and pest management. As one of the three most important grain crops that helps to fulfill food needs all across the globe, rice plays a key role in the current and future food security of the world. Currently, no book covers all aspects of rice production in the rice-growing areas of world. This book fills that gap by highlighting the diverse production and management practices as well as the various rice genotypes in the salient, rice-producing areas in Asia, Europe, Africa, the Americas, and Australia. Further, this text highlights harvesting, threshing, processing, yields and rice products and future research needs. Supplemented with illustrations and tables, this text is essential for students taking courses in agronomy and production systems as well as for agricultural advisers, county agents, extension specialists, and professionals throughout the industry.

Download or read book The System of Rice Intensification and Conventional Rice Farming written by Tejendra Chapagain and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The System of Rice Intensification (SRI) involves the adoption of certain changes in management practices for rice cultivation that create a better growing environment for rice crops. The use of intermittent irrigation with alternate wet and dry intervals (AWD) and single transplanting of the younger seedlings in wider spacing areas are regarded as the key factors in SRI for better crop growth and productivity. Field experiments were conducted in Chiba, Japan during the two consecutive rice growing seasons (May-September) of 2008-09 to observe the effects of SRI components on rice crop performance, field environment, water savings, and water-wise rice production. The effects of the irrigation method, age of seedlings and spacing were evaluated in the 2008 rice season with eight treatment combinations in a split-split plot design (S-SPD). AWDI at 10 day intervals and continuous flooding throughout the cropping season were the two main plot factors while the effects of seedling age (14 and 21 days) and plant spacing (30x30 cm2 and 30x18 cm2) were evaluated as sub and sub-sub plot factors, respectively. The experimental results revealed that the SRI management with the proposed AWDI can save a significant amount of irrigation water (29%) without reduced grain yield (7.41t/h compared with 7.37t/ha from normal planting with ordinary water management). Water productivity was also observed to be significantly higher in all combinations of practices in AWDI plots: 1.74 g/liter with SRI management and AWDI as compared to 1.23 g/liter in normal planting with ordinary water management. In addition, the research outcomes showed a role of AWDI in minimizing pest and disease incidence, shortening the rice crop cycle and also improving the plant stand until harvest. Synergistic effects of younger seedlings and wider spacing were seen in tillering ability, panicle length and a number of filled grains that ultimately led to higher productivity with better grain quality. Field experiments with the complete sets of SRI practices were carried out in Randomized Complete Block Design (RCBD) during the 2009 rice growing season in the same field. SRI (with 8 day old seedlings) and conventional (with 22 day old seedlings) practices were the first factor (cultivation method), while organic and inorganic managements were evaluated as the second factor (management method) in the field experiments. The highest yield was observed through the conventional method with inorganic management (6.84t/h) that was on par with the organic SRI (6.59t/h) followed by organic conventional (6.48t/h). It was recorded as 5.92t/h in inorganic SRI management. Overall, the effects of SRI components were positive and significant on a per plant basis; however, they did not differ significantly in terms of grain yield per unit area. The development of healthy and vigorous roots, increased stem diameter, greater productive leaf area, longer panicles, greater number of filled grains, development of plants tolerant to insect-pest and disease, and reduced plant lodging percentage were some notable achievements with SRI management. Water savings and water-wise rice production are other important issues that are likely to draw the attention of rice researchers and farm communities to adopt SRI under scarce water conditions. However, comparatively better grain yields with conventional management methods underscore a need for further investigations in defining an appropriate combination of practices for SRI management, considering local soil properties, prevailing climate and critical watering stages in rice crop management.

This book was released on 2015-12-12 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The System of Rice Intensification, known as SRI, is a management strategy for crop improvement. Its ideas, insights and practices are based on scientifically validated knowledge for increasing the production of not only irrigated rice but of other crops as well. SRI represents a paradigm shift in agricultural thinking and practice toward agroecological farming that can be used by even the poorest smallholding farmers in ecologically fragile regions of the world to achieve food security in the face of the climate-change challenges ahead. When the author Norman Uphoff first learned about SRI in Madagascar in 1993, this production system which offered higher yields with reduced inputs seemed implausible to him. But the professor put aside his skepticism after seeing farmers who had been getting rice yields of just two tons per hectare produce four times more rice-for three years in a row-on their very poor soils, not changing their varieties or relying on agrochemical inputs, and using less water. Now, he's helping to disseminate this dramatically effective methodology with this accessible, easy-to-use sourcebook. It offers explanations, research references, vivid pictures, and concrete examples of the award-winning SRI methodology to anyone interested in the development of practicable sustainable food systems.
