Book excerpt: Excerpt from Lodging of Field Corn as Affected by Cultivation, Plant Population, Nitrogen Fertilizer, and Irrigation Treatment at the Irrigation Experiment Station, Prosser, Wash Lodging of field corn prior to harvest has become a serious problem in irrigated areas in central Washington since 1945. Lodging has been attributed to spindly stalks caused by greater plant populations per acre. The greater plant populations are the result of better stands from the use of seed treatments, control of soil pests, and higher seeding rates. The use of large quantities of commercial fertilizer also has been named as a contributory cause of lodging. At present, stands of plants per acre and applications of fertilizer contain ing 80 to 250 pounds of available nitrogen per acre are recommended practices for the growers in Washington State crop statistics in the Yakima Valley show yield increases of corn ranging from 20 to 40 percent during the 10-year period, 1946 - 56. Growers have reported that their fields often contain 50 to 60 percentage of lodged stalks. Mechanical harvesters cannot recover all the ears from lodged corn plants, thus resulting in a loss of grain to the farmer. N o lodging due to corn borer or lodging caused by stalk or root rots has been reported in irrigated fields of central Washington. The objectives of the studies on lodging of field corn were: (1) To determine the effects of cultivation, nitrogen fertilization, and plant population on yields and lodging of field corn; (2) to take certain plant measurements and to determine the force required to break the stalks mechanically at a certain stage of growth as a means of evaluating resistance to lodging; and (3) to determine the effects of certain irrigation treatments on lodging.

Download or read book Response of Field Corn to Irrigation Plant Population and Nitrogen on Soils of the Willamette Catena written by Jimmie Lee Andersen and published by . This book was released on 1963 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to make a preliminary investigation of the productivity of some of the soils within the Willamette catena under different systems of soil management. The study was carried out at four experimental sites near Corvallis, Oregon, during the 1962 growing season. The soil at each site was representative of a different soil series. The soil series were Willamette, Woodburn, Amity, and Dayton which are well-drained, moderately well drained, imperfectly drained, and poorly drained, respectively. Productivity was measured in terms of shelled corn yield. The eight treatments (systems of soil managements) were different combinations of irrigation, plant population, and nitrogen fertilization practices. The irrigation treatments were irrigated and non-irrigated. The Ievels of plant population were 9000, 14000, 18000, and 22000 plants per acre. The rates of nitrogen fertilization were 60 and 180 pounds of N per acre. A second objective of this study was to measure the response of field corn to each of the three soil management practices. Data pertaining to the effects of the three practices on shelling percentage and ear moisture at harvest, as well as grain yield, were collected. There were significant yield responses to irrigation when accompanied by higher levels of plant population at all sites. Generally, yield responses to higher levels of plant population and the higher rate of nitrogen fertilization were measured on the irrigated plots, but not on the non-irrigated plots. The shelling percentage on the irrigated plots was higher than that on the non-irrigated plots only at the Amity and Dayton sites. Apparently, plant population and nitrogen had no effect on shelling percentage. The amount of moisture in the ears at harvest was apparently not affected by irrigation, plant population, and nitrogen fertilization practices. In general, the productivities of the soils at the Willamette, Woodburn, and Amity sites were similar and significantly greater than at the Dayton site under all systems of soil management.

Available in PDF, EPUB and Kindle. Book excerpt: In this major 1993 work, Lloyd Evans provides an integrated view of the domestication, adaptation and improvement of crop plants, bringing together genetic diversity, plant breeding, physiology and aspects of agronomy. Considerations of yield and maximum yield provide continuity throughout the book. Food, feed, fibre, fuel and pharmaceutical crops are all discussed. Cereals, grain legumes and root crops, both temperate and tropical, provide many of the examples, but pasture plants, oilseeds, leafy crops, fruit trees and others are also considered. After the introductory chapter, the increasing significance of crop yields to the world's food supply is highlighted. The next three chapters consider changes to crop plants over the last ten thousand years, including domestication, adaptation and improvement. Aimed at research workers and advanced students in crop physiology and ecology, agronomy and plant breeding, this book also reaches conclusions of relevance to those concerned with developmental policy, agricultural research and management, environmental quality, resource depletion and human history.

This book was released on 2017-03-15 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents ongoing research and ideas related to earth observations and global change, natural hazards and disaster management studies, with respect to geospatial information technology, remote sensing, and global navigation satellite systems. Readers will discover uses of advanced geospatial tools, spatiotemporal models, and earth observation systems. Chapters identify the international aspects of the coupled social, land and climate systems in global change studies, and consider such global challenges as agriculture monitoring, the smart city, and risk assessment. The work presented here has been carefully selected, edited, and peer reviewed in order to advance research and development, as well as to encourage innovative applications of Geomatics technologies in global change studies. The book will appeal not only to academicians, but also to professionals, politicians and decision makers who wish to learn from the very latest and most innovative, quality research in this area of global change and natural disaster management. /divContributions are drawn from revised submissions based on state-of-the-art papers from the 7th GiT4NDM - 5th EOGC, 2015 event.
