Working with Dynamic Crop Models PDF Author: Daniel Wallach
Publisher: Elsevier
ISBN: 008046193X
Category : Technology & Engineering
Languages : en
Pages : 465

Book Description
Mathematical models are being used more and more widely to study complex dynamic systems (global weather, ecological systems, hydrological systems, nuclear reactors etc. including the specific subject of this book, crop-soil systems). The models are important aids in understanding, predicting and managing these systems. Such models are complex and imperfect. One fundamental research direction is to seek a better understanding of how these systems function, and to propose mathematical expressions embodying that understanding. However, this is not sufficient. It is also essential to have tools (often mathematical and statistical methods) to aid in developing, improving and using the models built from those equations. The book is specifically concerned with the application of methods to crop models, but much of the material is also applicable to dynamic system models in other fields. The goal of this book is to fill that gap.* State-of-the-art methods explained simply and illustrated specifically for crop models* Parameter estimation – applying statistical methods to the complex case of crop models, including Bayesian methods * Includes model evaluation, understanding and estimating prediction error* Offers a unique data assimilation by using the Kalman filter and beyond

Understanding Options for Agricultural Production

Understanding Options for Agricultural Production PDF Author: G.Y. Tsuji
Publisher: Springer Science & Business Media
ISBN: 9401736243
Category : Science
Languages : en
Pages : 405

Book Description
The first premise of this book is that farmers need access to options for improving their situation. In agricultural terms, these options might be manage ment alternatives or different crops to grow, that can stabilize or increase household income, that reduce soil degradation and dependence on off-farm inputs, or that exploit local market opportunities. Farmers need a facilitating environment, in which affordable credit is available if needed, in which policies are conducive to judicious management of natural resources, and in which costs and prices of production are stable. Another key ingredient of this facilitating environment is information: an understanding of which options are viable, how these operate at the farm level, and what their impact may be on the things that farmers perceive as being important. The second premise is that systems analysis and simulation have an impor tant role to play in fostering this understanding of options, traditional field experimentation being time-consuming and costly. This book summarizes the activities of the International Benchmark Sites Network for Agrotechnology Transfer (IBSNAT) project, an international initiative funded by the United States Agency for International Development (USAID). IBSNAT was an attempt to demonstrate the effectiveness of understanding options through systems analysis and simulation for the ultimate benefit of farm households in the tropics and subtropics. The idea for the book was first suggested at one of the last IBSNAT group meetings held at the University of Hawaii in 1993.

Book Description
The focus of technology development in agriculture in the last half of 20th century was to increase the production efficiency of the farm. For this, the Indian farmers should be updated with latest knowledge to compete for global marketing. They must have the right information at the right time which is possible through new information technologies resulted in many non-agricultural fields. In the world of Information of Communication Technology, the most commonly available IT tools for transfer of agricultural technology in Indian context are radio, television, video, telephone and mobile phone, printed media, computer and internet. This book is an outcome of the rich experiences of research work carried out by the editors. Information technology has rooted well as one of the tools of Transfer of Technology which are being used by both public and private sectors for the benefit of farmeVillage Knowledge Centres of MSSRF, E-Choupals of Indian Tobacco Company, Kisan Kendras of Rallies, Kisan Bharath Kendras of United Phosphorus Limited, Cyber Extension services of EID Parry's, Kisan Call Centres (KCC), AGRISNET AGMARKNET are few good examples to quote. Hence, this book entitled Extension of Technologies: From Labs to RFarms is an effort to limelight the potentiality of this tool in the field of agricultural extension in general and transfer of technology in particular.

Book Description
Detailed hydro-geological investigations were carried out while implementing SCARPs in the Chaj Doab. These investigations yielded a data set of groundwater quality at different depths of the aquifers (spatial) especially in the SCARP-II saline zone. In MREP area, 138 public tubewells, having strainers from 30-35 m till 60-75 m depth of the aquifer, were installed during the 1970s to help meet the irrigation water demand at farm level. The MREP, who was made responsible for operation and maintenance of these deep tubewells, continuously monitored the performance of these tubewells as well. Therefore, the pumped groundwater quality data (temporal) of these spatially distributed tubewells was also available. This data availability served as a basis for site selection using GIS analysis.The GIS analysis, which was used in classifying different groundwater quality zones, helped in selecting fifteen villages (thirteen in MREP area and two in SCARP-II saline zone) that have hydro-geological potential for installing and operating skimming wells. In these selected villages, preliminary survey was carried out to get information on the farmers' willingness to use skimming well technology. Based on the GIS analysiS and preliminary survey, different sites in six villages (two in SCARP-II saline zone, and four in SCARP-II non-saline zone) were selected to carry out the Diagnostic AnalysiS (DA) for investigating the hydro-salinity and hydro-geological conditions of the aquifer. Based on the DA results, four villages for the Participatory Rural Appraisal (PRA) to assess farmers' practices and perceptions in opting for skimming well technologies.
