Download or read book Corn and Grain Sorghum Comparison written by Yared Assefa and published by Academic Press. This book was released on 2013-12-16 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corn and grain sorghum (Sorghum bicolor subsp. bicolor L) are among the top cereal crops world wide, and both are key for global food security. Similarities between the two crops, particularly their adaptation for warm-season grain production, pose an opportunity for comparisons to inform appropriate cropping decisions. This book provides a comprehensive review of the similarities and differences between corn and grain sorghum. It compares corn and sorghum crops in areas such as morphology, physiology, phenology, yield, resource use and efficiency, and impact of both crops in different cropping systems. Producers, researchers and extension agents in search of reliable scientific information will find this in-depth comparison of crops with potential fit in dryland and irrigations cropping systems particularly valuable. - Presents a wide range of points of comparison - Offers important insights for crop decision making

This book was released on 2002 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the context of improving water productivity, there is a growing interest in deficit irrigation, an irrigation practice whereby water supply is reduced below maximum levels and mild stress is allowed with minimal effects on yield. Under conditions of scarce water supply and drought, deficit irrigation can lead to greater economic gains than maximizing yields per unit of water for a given crop; farmers are more inclined to use water more efficiently, and more water-efficient cash crop selection helps optimize returns. However, this approach requires precise knowledge of crop response to water as drought tolerance varies considerably by species, cultivar and stage of growth. The studies present the latest research concepts and involve various practices for deficit irrigation. Both annual and perennial crops were exposed to different levels of water stress, either during a particular growth phase, throughout the whole growing season or in a combination of growth stages. The overall finding, based on the synthesis of the different contributions, is that deficit or regulated-deficit irrigation can be beneficial where appropriately applied. Substantial savings of water can be achieved with little impact on the quality and quantity of the harvested yield. However, to be successful, an intimate knowledge of crop behavior is required, as crop response to water stress varies considerably.

Download or read book Integrated Pest Management written by Dale G. Bottrell and published by . This book was released on 1979 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated pest management (IPM) is the selection, integration, and implementation of pest control based on predicted economic, ecological, and sociological consequences. IPM seeks maximum use of naturally occurring pest controls, including weather, disease agents, predators, and parasites. In addition, IPM utilizes various biological, physical, and chemical control and habitat modification techniques. Artificial controls are imposed only as required to keep a pest from surpassing intolerable population levels predetermined from accurate assessments of the pest damage potential and the ecological, sociological, and economic costs of the control measures. The presence of a pest species does not necessarily justify action for its control, and in fact tolerable infestations may be desirable, providing food for important beneficial insects, for example.

Download or read book Crop Photosynthesis written by N.R. Baker and published by Elsevier. This book was released on 2013-10-22 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since photosynthetic performance is a fundamental determinant of yield in the vast majority of crops, an understanding of the factors limiting photosynthetic productivity has a crucial role to play in crop improvement programmes. Photosynthesis, unlike the majority of physiological processes in plants, has been the subject of extensive studies at the molecular level for many years. This reductionist approach has resulted in the development of an impressive and detailed understanding of the mechanisms of light capture, energy transduction and carbohydrate biosynthesis, processes that are clearly central to the success of the plant and the productivity of crops. This volume examines in the widest context the factors determining the photosynthetic performance of crops. The emphasis throughout the book is on the setting for photosynthesis rather than the fundamental process itself. The book will prove useful to a wide range of plant scientists, and will encourage a more rapid integration of disciplines in the quest to understand and improve the productivity of crops by the procedures of classical breeding and genetic manipulation.
