Book Synopsis Deficit Irrigation Practices by : Food and Agriculture Organization of the United Nations
Download or read book Deficit Irrigation Practices written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. 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.

Book excerpt: This manual (most of whose modules were originally published 2001-2002) aims at strengthening various aspects of irrigation development, mainly emphasizing the engineering, agronomic and economic aspects of smallholder irrigation, in view of the limited practical references available in this area. It also introduces the irrigation practitioner to the social, health and environmental aspects, providing a bridge between the various disciplines involved in irrigation development.--Publisher's description.

Book Synopsis Modernizing Irrigation Management by : Daniel Renault
Download or read book Modernizing Irrigation Management written by Daniel Renault and published by Food & Agriculture Org.. This book was released on 2007 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication describes the MASSCOTE methodology, illustrated by several applications in Asia. MASSCOTE is a comprehensive methodology for analysing the modernization of canal operation. The aim is to enable experts to work together with users in determining improved processes for cost-effective service-oriented management. It is based on previous tools and approaches widely used in Asia by FAO in its modernization training programme (rapid appraisal procedures and benchmarking). From diagnosis through the formulation of operational units and the planning of a service (based on the vision agreed upon with the users), MASSCOTE entails a systematic, ten-step, mapping exercise. The accompanying CD-ROMs contain the full document in English, excerpts in French, a draft version in Arabic and Chinese, training presentations and material, and a number of documents and references on irrigation system operation and management [System requirements: PC with Intel Pentium(r) processor and Microsoft(r)Windows 95/98/200/Me/NT/XP; 256 MB of RAM; 50 MB of available hard-disk space; SuperVGA monitor; 256 colours at 1024x768; Adobe Acrobat(r) Reader (not included on CD-ROM)]

Book Synopsis Crop Water Requirements by : J. Doorenbos
Download or read book Crop Water Requirements written by J. Doorenbos and published by . This book was released on 1992 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is intended to provide guidance in determining crop water requirements and their application in planning, design and operation of irrigation projects; Part I.1 presents suggested methods to derive crop water requirements. The use of four well-known methods for determining such requirements is defined to obtain reference crop evapotranspiration (ETo), which denotes the level of evapotranspiration for different set of climatic data. To derive the evapotranspiration for a specific crop, relationships between crop evapotranspiration (ETcrop) and reference crop evapotranspiration (ETo) are given in Part I.2 for different crops, stages of growth, length of growing season and prevailing climatic conditions. The effect of local conditions on crop water requirements is given in Part I.3; this includes local variation in climate, advection, soil water availability and agronomic and irrigation methods and practices. Calculation procedures are presented together with examples. A detailed discussion on selection and calibration of the presented methodologies together with the data sources is given in Appendix II. A computer programme on applying the different methods is given in Appendix III. Part II discusses the application of crop water requirements data in irrigation project planning, design and operation. Part II. 1 deals with deriving the field water balance, which in turn forms the basis for predicting seasonal and peak irrigation supplies for general planning purposes. Attention is given to irrigation efficiency and water requirements for cultural practices and leaching of salts. In Part II. 2 methods are presented to arrived at field and scheme supply schedules with emphasis towards the field water balance and field irrigation management. Criteria are given for operating the canal system using different methods of water delivery, and for subsequent design parameters of the system. Suggestions are made in Part II. 3 on refinement of field and project supply schedules once the project is in operation. The presented guidelines are based on measured data and experience obtained covering a wide range of conditions. Local practical, technical, social and economic considerations will, however, affect the planning criteria selected. Therefore caution and a critical attitude should still be taken when applying the presented methodology.
