Download or read book Growing Winter Wheat on the Great Plains written by Ellery Channing Chilcott and published by . This book was released on 1917 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Limited rainfall is the controlling factor in crop production in the Great Plains. The average yields of a series of years can be foretold from the records of past years; but because the rainfall is fluctuating in amount and uncertain in distribution, the yields of a simple year can not be foretold with any certainty. The chances of success are, however, much better when the soil is wet to a considerable depth at seeding time than they are when the soil contains little or no available water at that time. The relation between the amount of water in the soil at seeding time and the yield is much closer with winter wheat than with other crops. This crop should, therefore, be seeded on the best-prepared land and that in which the greatest amount of water is stored. Except in the southern section, the response of winter wheat to summer tillage is greater than that of any other crop. Summer-tilled land should be seeded to winter wheat wherever this crop can be grown. The growth of corn is one of the best preparations for winter wheat, especially north of Kansas. With increase in the length of season and the time between harvest and seeding, there is an increase in the value of early preparation for winter wheat. In the northern section the crop can be replaced with spring wheat without serious loss. In the central section winter wheat has a greater advantage over spring wheat and can not be replaced by the latter without serious loss. In the southern section, winter wheat is less certain and less productive than farther north and can not be replaced by spring wheat. It is, however, profitably raised under favorable conditions of oil, season, and preparation. In this section particularly it should be recognized that the chances of producing a crop are low when it is seeded on land that does not contain water enough in storage to wet the soil to a depth of 3 feet."--Page 2

Book excerpt: Climate change is a serious threat to field crop production and food security. It has negative effects on food, water, and energy security due to change in weather patterns and extreme events such as floods, droughts, and heat waves, all of which reduce crop productivity. Over six chapters, this book presents a comprehensive picture of the importance of agronomy as it relates to the United Nations’ Sustainable Development Goals. With an emphasis on the goals of Zero Hunger and Climate Change, this volume examines sustainable agronomic practices to increase crop productivity and improve environmental health.

This book was released on 2012-12-06 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Third Edition of Principles of Seed Science and Technology. like the first two editions. is written for the advanced undergraduate student or lay person who desires an introduction to the science and technology ofseeds. The first eight chapters presentthe seed as abiologicalsystemand coverits origin. development. composition. function (and sometimes nonfunctionJ, performance and ultimate deterioration. The last seven chapters present the fundamentals ofhow seedsare produced. conditioned. evaluated and distributed in our modern agricultural society. A new chapter on seed enhancement has been added to reflect the significant advancements made in the last 10 years on new physiological and molecular biology techniques to further enhance seed performance. Because of the fundamental importance of seeds to both agriculture and to all of society. we have taken great care to present the science and technology of seeds with the respect and feeling this study deserves. We hope that this feeling will becommuni cated to our readers. Furthermore. we have attempted to present information in a straight-forward. easy-to-read manner that will be easily understood by students and lay persons alike. Special care has been taken to address both current state-of-the-art as well as future trends in seed technology. . We believe this Third Edition represents a new level in presenting information that appeals to advanced undergraduate students as well as to those desiring more fundamental information on seed form and function. At the same time. it continues to havethestrengths ofthe firsttwoeditions.initsreadabilityaswellas itscomprehensive coverage of the broader area of seed science and technology.
Download or read book Soil Microbial Community and Winter Wheat Performance Across Eastern Washington State written by Nickolas Allen Frisbee and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional crop breeding strategies focus on genetic gain through phenotypic selection, but year to year increases in yield are variable. A primary focus on aboveground yield improvement in breeding programs may cause breeding pipelines to become stagnant with dominant yield traits. Whereas a diversified gene pool could lead to more natural resistance to environmental stressors. To better understand plant-rhizosphere interactions in winter wheat that could lead to increased stress resilience, we need to dive deeper into the mystery that surrounds the rhizosphere and how it can be used to produce a more economic and efficient crop. This research focuses on examining differences in microbial taxonomic and functional diversity, and how those factors are associated with yield and grain quality in 18 cultivars of winter wheat that occur across multiple environments in Washington state. Environmental factors impact many interactions within the soil rhizosphere that can lead to different performance of winter wheat. This led to the overarching questions: How variable is the rhizosphere microbiome under winter wheat production varieties in Eastern Washington? And secondly, are these differences, if present, associated with specific environmental factors, wheat yield or grain quality metrics? Our primary project objectives were to characterize the following within the rhizosphere of winter wheat varieties in Eastern Washington: 1) taxonomic diversity and richness of the rhizosphere microbiome 2) microbial soil enzyme activity levels and 3) microbial siderophore production that assists with Fe acquisition. Our overarching goal is to identify wheat varieties that improve soil health through microbiome changes and identify any associations among the microbial community with variety performance and grain micronutrient concentrations that might improve grower economics or human health.

This book was released on 2020-07-22 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Irrigation System Selection for Semi-Arid Regions compares the various types of available irrigation systems for different regions and conditions, and explains how to analyze field data to determine the suitability of the land for surface, sprinkle, or drip irrigation systems. The book focuses on strategies for irrigation development and management and examines deficit irrigation and partial root-zone drying systems. Also, solute leaching modeling under different irrigation systems, soil moisture conditions, and organic fertilizer application in arid areas are discussed. Further, it examines multi-criteria decision making for irrigation management and the appraisal of agricultural lands for irrigation in hot, sub-humid regions. Features: Presents comparative analysis to aid in the selection of the most appropriate types of irrigation systems according to land characteristics. Includes numerous practical case studies. Offers parametric evaluation systems for irrigation purposes. Considers data from semi-arid zones, each with different sub-climates. Focusing on semi-arid land, the book highlights parametric evaluation systems for irrigation purposes, along with the use of analytical hierarchy processes integrated with GIS to determine which systems are best suited. This comprehensive and well-illustrated handbook will be of great interest to students, professionals, and researchers involved with all aspects of irrigation in semi-arid regions.
