Trickle Irrigation for Crop Production


Book Description

An entirely new agricultural technology, trickle or drip irrigation, began its development in the early 1960's. Initial progress was sporadic even though the advantages in water management with trickle systems were recognized. Operators were reluctant to use the system because of its high initial cost and questions regarding its reliability. Once the main problems were isolated and solutions developed to make the system reliable, rapid acceptance by the growers resulted. Today, trickle irrigation is being used on crops that were earlier considered to be uneconomical. This multi-purpose handbook brings together current knowledge from various engineering and scientific disciplines (crop, hydraulic, irrigation and soil sciences) needed for understanding the trickle irrigation system for crop production. The two dozen contributors are experts on the various subjects, which range from the basic to the more practical aspects of trickle irrigation. Major topics include design, operation and management - with individual chapters covering historical development, emitter construction and clogging, system design, water and salt distribution, automation, water treatment, irrigation scheduling, maintenance, fertilization and salinity.The book greatly expands the scope of research papers, reviews, extension bulletins, and updates earlier text with new information on trickle systems. A multi-disciplinary approach has been taken on a multi-faceted subject. The material contained in the book is the most comprehensive yet developed on the topic. Illustrative sample problems and solutions provide field operators and extension personnel with information needed to install and maintain trickle systems. As it is up-to-date, it is useful as a teaching and reference source for students, manufacturers and irrigation system operators as well as irrigation and crop specialists, and consultants.




Water Requirements for Irrigation and the Environment


Book Description

Irrigated agriculture produces about 40% of all food and fibre on about 16% of all cropped land. As such, irrigated agriculture is a productive user of resources; both in terms of yield per cropped area and in yield per volume of water consumed. Many irrigation projects, however, use (divert or withdraw) much more water than consumed by the crop. The non-consumed fraction of the water may cause a variety of undesirable effects ranging from water-logging and salinity within the irrigated area to downstram water pollution. This book discusses all components of the water balance of an irrigated area; evapotranspiration (Ch.2), effective precipitation (Ch.3) and capillary rise from the groundwater table (Ch.4). Chapter 5 then combines all components into a water management strategy that balances actual evapotranspiration (and thus crop yield) with the groundwater balance of the irrigated area (for a substainable environment). Chapter 6 presents CRIWAR 3.0, a simulation program that combines all water balance components into a single simulation procedure. The chapter describes the use of the CRIWAR software for developing water requirement tables and other useful information based on the selected water management strategy. This version greatly expands upon the capabilities of previously published programs.




CRC Handbook of Plant Science in Agriculture


Book Description

First published in 1987, this two-volume set is an exhaustive compilation of the most recent data on economically important crops. Volume I presents information on genetics, botany and growth of crop plants, while Volume II covers the production of Crops and their utilization.










Water Management, Purificaton, and Conservation in Arid Climates


Book Description

This new three volume series presents a broad and integrated approach to water management, purification, and conservation in arid climates. Volume one includes an introductory chapter on water problems and water resources in arid climates followed by specific chapters covering various aspects of water management. Volumes two and three deal with water purification and water conservation, respectively. Many textbooks on water issues normally deal with only one of these areas. This series covers all three areas with an emphasis on the problems faced by arid regions. The three volume series will appeal to industry specialists in desalination and wastewater treatment, irrigation engineers, graduate and undergraduate students in hydrology, water management and conservation professionals, government personnel involved in water resources development, decision makers, environmentalists, employees of the petrochemical industry, and individuals wishing to specialize in water management, purification and conservation.
