Statistical Procedures for Agricultural Research


Book Description

Here in one easy-to-understand volume are the statistical procedures and techniques the agricultural researcher needs to know in order to design, implement, analyze, and interpret the results of most experiments with crops. Designed specifically for the non-statistician, this valuable guide focuses on the practical problems of the field researcher. Throughout, it emphasizes the use of statistics as a tool of research—one that will help pinpoint research problems and select remedial measures. Whenever possible, mathematical formulations and statistical jargon are avoided. Originally published by the International Rice Research Institute, this widely respected guide has been totally updated and much expanded in this Second Edition. It now features new chapters on the analysis of multi-observation data and experiments conducted over time and space. Also included is a chapter on experiments in farmers' fields, a subject of major concern in developing countries where agricultural research is commonly conducted outside experiment stations. Statistical Procedures for Agricultural Research, Second Edition will prove equally useful to students and professional researchers in all agricultural and biological disciplines. A wealth of examples of actual experiments help readers to choose the statistical method best suited for their needs, and enable even the most complicated procedures to be easily understood and directly applied.

The Fault Lines of Farm Policy


Book Description

At the intersection of the growing national conversation about our food system and the long-running debate about our government’s role in society is the complex farm bill. American farm policy, built on a political coalition of related interests with competing and conflicting demands, has proven incredibly resilient despite development and growth. In The Fault Lines of Farm Policy Jonathan Coppess analyzes the legislative and political history of the farm bill, including the evolution of congressional politics for farm policy. Disputes among the South, the Great Plains, and the Midwest form the primordial fault line that has defined the debate throughout farm policy’s history. Because these regions formed the original farm coalition and have played the predominant roles throughout, this study concentrates on the three major commodities produced in these regions: cotton, wheat, and corn. Coppess examines policy development by the political and congressional interests representing these commodities, including basic drivers such as coalition building, external and internal pressures on the coalition and its fault lines, and the impact of commodity prices. This exploration of the political fault lines provides perspectives for future policy discussions and more effective policy outcomes.

An evolving paradigm of agricultural mechanization development: How much can Africa learn from Asia?


Book Description

Agricultural mechanization in Africa south of the Sahara — especially for small farms and businesses — requires a new paradigm to meet the needs of the continent’s evolving farming systems. Can Asia, with its recent success in adopting mechanization, offer a model for Africa? An Evolving Paradigm of Agricultural Mechanization Development analyzes the experiences of eight Asian and five African countries. The authors explore crucial government roles in boosting and supporting mechanization, from import policies to promotion policies to public good policies. Potential approaches presented to facilitating mechanization in Africa include prioritizing market-led hiring services, eliminating distortions, and developing appropriate technologies for the African context. The role of agricultural mechanization within overall agricultural and rural transformation strategies in Africa is also discussed. The book’s recommendations and insights should be useful to national policymakers and the development community, who can adapt this knowledge to local contexts and use it as a foundation for further research.

Feeding the World


Book Description

The astounding success of agricultural research has enabled farmers to produce increasingly more—and more kinds—of food throughout the world. But with a projected 9 billion people to feed by 2050, veteran researcher Gale Buchanan fears that human confidence in this ample supply, especially in the US, has created unrealistic expectations for the future. Without a working knowledge of what types and amounts of research produced the bounty we enjoy today, we will not be prepared to support the research necessary to face the challenges ahead, including population growth, climate change, and water and energy scarcity. In this book, Buchanan describes the historical commitment to research and the phenomenal changes it brought to our ability to feed ourselves. He also prescribes a path for the future, pointing the way toward an adequately funded, more creative agricultural research system that involves scientists, administrators, educators, farmers, politicians, and consumers; resides in one “stand alone” agency; enjoys a consistent funding stream; and operates internationally.
