Download or read book Maize in Thailand production systems constraints and research priorities written by and published by CIMMYT. This book was released on 2004 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maize is one of five major crops grown in the uplands of Thailand, along with rice, cassava, sugar cane, and rubber trees. Government-promoted crop diversification, increased population growth, improved transportation networks, inter national trade, expansion of upland farming areas, and increased demand for grains from the domestic livestock and poultry industry stimulated Thailand’s maize production beginning in the 1980s. However, Thailand’s domestic maize supply is currently not sufficient to meet the needs of its in-country demands, and small quantities have to be imported. This study characterized the social and biophysical maize production environment of Thailand; examined its response to increasing maize demand; determined constraints to future productivity growth; indicated the potential environmental consequences, and examined the options available for promoting sustainable growth in maize production.

Download or read book Maize in India written by and published by CIMMYT. This book was released on 2005 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maize is a promising substitute crop allowing diversification from the rice-wheat system in the upland areas of India. The crop has high production potential, pr ovided the available improved hybrids and composites reach the farming community. This study found that major biotic production constraints were Echinocloa, Cynodon dactylon, rats, and termites, which reduced maize production levels by more than 50%. Other important abiotic and biotic stresses listed in descending order of importance were: caterpillars, water stress, stem borers, weevils, zinc deficiency, rust, seed/seedling blight, cutworm, and leaf blight. Non-availability of improved seeds, inadequate input markets, inef fective technology dissemination, and lack of collective action were the principal socio-economic constraints.
Download or read book Sustainable Crop Productivity and Quality under Climate Change written by Fulai Liu and published by Academic Press. This book was released on 2022-06-07 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable Crop Productivity and Quality under Climate Change: Responses of Crop Plants to Climate Change explores the physiological, biochemical, and molecular basis of the responses of major crop plants to a range of climate change scenarios. From the development of climate-resilient crop varieties which lead to enhanced crop productivity and quality to better utilization of natural resources to ensure food security through modern breeding techniques, it presents insights into improving yield while securing the environment. Understanding the impact of climate on crop quality and production is a key challenge of crop science. Predicted increases in climate variability necessitate crop varieties with intrinsic resilience to cooccurring abiotic stresses such as heat, drought, and flooding in a future climate of elevated CO2. This book presents a much-needed mechanistic understanding of the interactions between multiple stress responses of plants that is required to identify and take advantage of acclimation traits in major crop species as a prerequisite for securing robust yield and good quality. This book is an excellent reference for crop and agricultural scientists, plant scientists, and researchers working on crop plant ecophysiology/stress physiology and future crop production. Includes breeding strategies for developing climate-resilient crop varieties Presents a comprehensive overview of the current challenges, approaches, and best practices Authored by frontline researchers and experts who work at the fields of climate change impacts on crop productivity
Download or read book Molecular Breeding for Sustainable Crop Improvement written by Vijay Rani Rajpal and published by Springer. This book was released on 2016-02-02 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world population is estimated to reach to more than 10 billion by the year 2050. These projections pose a challenging situation for the agricultural scientists to increase crops productivity to meet the growing food demands. The unavailability and/or inaccessibility to appropriate gene pools with desired traits required to carry out genetic improvement of various crop species make this task formidable for the plant breeders. Incidentally, most of the desired genes reside in the wild genetic relatives of the crop species. Therefore, exploration and characterization of wild genetic resources of important crop species is vital for the efficient utilization of these gene pools for sustainable genetic improvements to assure food security. Further, understanding the myriad complexities of genic and genomic interactions among species, more particularly of wild relatives of crop species and/or phylogenetically distant germplasm, can provide the necessary inputs to increase the effectiveness of genetic improvement through traditional and/or genetic engineering methods. This book provides comprehensive and latest insights on the evolutionary genesis of diversity, access and its utilization in the evolution of various crop species. A comprehensive account of various crops, origin, exploitation of the primary, secondary and tertiary gene pools through breeding, biosystematical, cytogenetical and molecular phylogenetical relationships, and genetic enhancement through biotechnological interventions among others have been provided as the necessary underpinnings to consolidate information on the effective and sustainable utilization of the related genetic resources. The book stresses upon the importance of wild germplasm exploration, characterization and exploitation in the assimilation of important crop species. The book is especially intended for students and scientists working on the genetic improvement of crop species. Plant Breeders, Geneticists, Taxonomists, Molecular Biologists and Plant Biotechnologists working on crop species are going to find this book very useful.
Download or read book Remote Sensing Application written by Tofael Ahamed and published by Springer Nature. This book was released on 2022-05-06 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses solely on the issues of agriculture and forest productivity analysis with advanced modeling approaches to bring solutions to food-insecure regions of South and Southeast Asia. Advanced modeling tools and their use in regional planning provide an outstanding opportunity to contribute toward food production and environments. In this book, leading-edge research methodologies related to remote sensing and geospatial variability of soil, water, and regional agricultural production indicators and their applications are introduced together—a unique feature of the book is the domain of regional policy perspectives and allied fields. In regional policy planning, agriculture and forestry have a key role in food security and environmental conservation that depends on the geo-spatial variability of these factors. Over the years, nature and climate have determined the variability of soil type, soil quality, geographical deviation for habitat, water quality, water sources, urban influences, population growth, carbon stock levels, and water resources with rain-fed or irrigated land use practices. In addition, human nutritional values and dietary habits have brought cultural adaptation of either mono- or multi-cropping patterns in the region. To encompass all these above mentioned factors and classify regional variability for policy planning, satellite remote sensing and geographical information systems have the immense potential to increase agricultural and forest productivity to ensure the resilience of its sustainability. Therefore, the 13 chapters presented in this book introduce modeling techniques using the signatures of vegetation and water indices, land use and land change dynamics, climatic, and socioeconomic criteria through spatial, temporal, and statistical analysis. As well, remote sensing and in-depth GIS analysis are integrated with machine and deep learning algorithms to address natural uncertainties such as flash floods, droughts, and cyclones in agricultural production management.
Download or read book Rice maize systems in Asia current situation and potential written by and published by IRRI. This book was released on 2011 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rice-maize (R-M) cropping systems have emerged in recent years on 3.5 million hectares in Asia in response to the increasing demand from a rapidly expanding human population for rice and livestock products. They are rapidly spreading in southern and northeastern India and Bangladesh, driven by the rising demand for maize by the poultry and fish sectors and the tightening world export-import markets. The recent development of short-duration rice varieties and maize hybrids with improved drought tolerance is also providing opportunities for the expansion of R-M systems into areas of South Asia with insufficient irrigation or rain for continuous rice cultivation. Agroecologically, R-M systems have the potential to expand into broad climatic zones across Asia. Because strong economic multipliers exist between food production and feed and livestock production, more diversified cropping systems are also likely to become a key engine for economic growth in rural areas of Asia. This will contribute to more diversified diets, improved human nutrition, reduced poverty, and greater investment in other aspects of quality of life such as education and health care. R-M systems will also provide new business opportunities for the local agribusiness sector, including hybrid seed production and marketing, the fertilizer sector, the agricultural machinery sector, and the grain marketing and livestock feed-processing sector. Recognizing the importance of diversifying cropping systems in Asia and the need for system-level research to support new opportunities for agricultural development, IRRI and CIMMYT scientists, in collaboration with NARES partners, have recently begun work on R-M systems in many countries of Asia. This report contains information on a strategic assessment of R-M systems for 29 selected sites representing diverse soils, climate, and agroecosystems across nine countries in Asia (Bangladesh, China, India, Indonesia, Nepal, Pakistan, the Philippines, Thailand, and Vietnam). Conducted jointly by IRRI and CIMMYT, the process involves regional and site-level biophysical assessment, supported by socioeconomic evaluation using economic data at the regional level and some microeconomic data. Biophysical assessment includes agroecosystem characterization of R-M systems, analysis of historical daily climatic data, and regional-level prediction of yield potential for the 29 sites. The study then provides a detailed analysis of 10 selected sites to understand existing cropping systems, identify alternative potential systems, and explore measures to optimize these. The Cereal Systems Initiative for South Asia (CSISA), a project funded by the Gates Foundation and USAID in Bangladesh, India, Nepal, and Pakistan, was launched in early 2009. It now provides an overall strategy and a new umbrella for contributing new science and technologies to accelerate short- and long-term cereal production growth in South Asia's most important grain baskets. It builds on technologies developed and lessons learned from the Rice-Wheat Consortium (RWC) and many other investments in agricultural R & D by both the public and private sector. Through creating and facilitating innovative and effective public-/private-sector partnerships in key "hubs" in South Asia. CSISA will boost the deployment of existing varieties, hybrids, crop- and aquaculture-related management technologies, and market information. The results from the strategic assessment of R-M systems are already being used in several CSISA hubs.
