Download or read book Sheath Blight Disease of Rice written by K. Manibhushan Rao and published by Daya Books. This book was released on 1995 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sheat blight (ShB) is considered as one of the serious diseases of rice in Asian countries and the USA. The increase in ShB incidence is largely due to changes in the rice cultivation methods as well as in the use of early-maturing, semi-dwarf, high-yielding and N-responsive cultivars. Against this background, this monographic study is aimed primarily presenting the status of our knowledge by compiling the literature available as well as the author s own experience on rice diseases over three decades. The book is meant primarily for the graduate students, rice pathologists and extension workers. This compendium should not only stimulated further research but also will be used for ShB management. It traces the history of the disease, the casual agents, its nomenclature, taxonomy, morphology, physiology, variability, histopathology and ultra structure. It is profusely illustrated with excellent plates and number of tables which project the current status in a better way. Also information has been given on the disease management by induced resistance as well as biocontrol and the future resistance as well as biocontrol and the future perspectives on this important rice disease.

Download or read book Biological Control of Rice Diseases written by Samuel S. Gnanamanickam and published by Springer Science & Business Media. This book was released on 2009-07-14 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is suf?cient need to document all the available data on biological control of rice diseases in a small volume. Part of this need rests on the global importance of rice to human life. In the ?rst chapter, I have tried to show that rice is indeed life for most people in Asia and shortages in production and availability can lead to a food crisis. While rice is cultivated in most continents, biological disease management attains special relevance to rice farmers of Africa, Asia, and also perhaps, Latin America. These farmers are resource-poor and might not be able to afford the cost of expensive chemical treatments to control devastating rice pathogens such as Magnaporthe oryzae (blast), Xanthomonas oryzae pv. oryzae (bacterial leaf blight), Rhizoctonia solani (sheath blight) and the virus, rice tungro disease. In an earlier volume that I developed under the title, Biological Control of Crop Diseases (Dekker/CRC Publishers, 2002), I included transgenic crops generated for the management of plant pathogens as biological control under the umbrella of a broad de?nition. Dr Jim Cook who wrote the Foreword for the volume lauded the inclusion of transgenic crops and induced systemic resistance (ISR) as a positive trend toward acceptance of host plant resistance as part of biocontrol. I continue to subscribe to this view.

Download or read book Rice Improvement written by Jauhar Ali and published by Springer Nature. This book was released on 2021-05-05 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY 4.0 license. By 2050, human population is expected to reach 9.7 billion. The demand for increased food production needs to be met from ever reducing resources of land, water and other environmental constraints. Rice remains the staple food source for a majority of the global populations, but especially in Asia where ninety percent of rice is grown and consumed. Climate change continues to impose abiotic and biotic stresses that curtail rice quality and yields. Researchers have been challenged to provide innovative solutions to maintain, or even increase, rice production. Amongst them, the ‘green super rice’ breeding strategy has been successful for leading the development and release of multiple abiotic and biotic stress tolerant rice varieties. Recent advances in plant molecular biology and biotechnologies have led to the identification of stress responsive genes and signaling pathways, which open up new paradigms to augment rice productivity. Accordingly, transcription factors, protein kinases and enzymes for generating protective metabolites and proteins all contribute to an intricate network of events that guard and maintain cellular integrity. In addition, various quantitative trait loci associated with elevated stress tolerance have been cloned, resulting in the detection of novel genes for biotic and abiotic stress resistance. Mechanistic understanding of the genetic basis of traits, such as N and P use, is allowing rice researchers to engineer nutrient-efficient rice varieties, which would result in higher yields with lower inputs. Likewise, the research in micronutrients biosynthesis opens doors to genetic engineering of metabolic pathways to enhance micronutrients production. With third generation sequencing techniques on the horizon, exciting progress can be expected to vastly improve molecular markers for gene-trait associations forecast with increasing accuracy. This book emphasizes on the areas of rice science that attempt to overcome the foremost limitations in rice production. Our intention is to highlight research advances in the fields of physiology, molecular breeding and genetics, with a special focus on increasing productivity, improving biotic and abiotic stress tolerance and nutritional quality of rice.
Download or read book Statistical Procedures for Agricultural Research written by Kwanchai A. Gomez and published by John Wiley & Sons. This book was released on 1984-02-17 with total page 698 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here in one easy-to-understand volume are the statistical procedures and techniques the agricultural researcher needs to know in order to design, implement, analyze, and interpret the results of most experiments with crops. Designed specifically for the non-statistician, this valuable guide focuses on the practical problems of the field researcher. Throughout, it emphasizes the use of statistics as a tool of research—one that will help pinpoint research problems and select remedial measures. Whenever possible, mathematical formulations and statistical jargon are avoided. Originally published by the International Rice Research Institute, this widely respected guide has been totally updated and much expanded in this Second Edition. It now features new chapters on the analysis of multi-observation data and experiments conducted over time and space. Also included is a chapter on experiments in farmers' fields, a subject of major concern in developing countries where agricultural research is commonly conducted outside experiment stations. Statistical Procedures for Agricultural Research, Second Edition will prove equally useful to students and professional researchers in all agricultural and biological disciplines. A wealth of examples of actual experiments help readers to choose the statistical method best suited for their needs, and enable even the most complicated procedures to be easily understood and directly applied.
