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.

This book presents a simple, straightforward discussion of the principles and processes involved in the production of grain yield by agronomic crops, and how these processes underlie and influence management decisions. The focus is on grain crops, principally maize and soybean, although the general principles apply equally well to cereals, grain legumes and oil crops. Intended for researchers in crop science, agronomy and plant science, and crop production practitioners, this book will enable readers to make better, more informed management decisions; decisions that will help maintain a well-fed world in the future.

Commercial crop production in the 21st century is a highly technical pursuit. There is an economic imperative for farmers to make a reasonable living through increased productivity, cost containment and market satisfaction. Contending with the variability of the Australian climate remains a major challenge. Of increasing importance is the environmental imperative - the need to manage soil structure decline, erosion, acidity and salinity. Involved also are boidiversity preservation and thewater reform agenda. The fourth edition of Principles of Field Crop Production addresses these issues and provides a contemporary understanding involved in the production of crops in Australia. The book provides background on the evolution of farming systems. A new chapter on climate variability and its predictability is included as are new treatments of rotations, weeds, pests and diseases. An introduction to supply chain management provides the reader with an understanding of market forces.All chapters have been updated and the principles clearly defined.

Understanding Climate Change Impacts on Crop Productivity and Water examines the greenhouse gas emissions and their warming effect, climate change projections, crop productivity and water. The book explores the most important greenhouse gases that influence the climate system, technical terms associated with climate projections, and the different mechanisms impacting crop productivity and water balance. Adaptive and mitigative strategies are proposed to cope with negative effects of climate change in particular domains. This book will help researchers interested in climate change impacts on the atmosphere, soil and plants. Uncovers links between climate change and its impact on crop and water outputs Integrates information on greenhouse gas cycles and mathematical equations into climate/crop models for analysis and seasonal prediction systems Provides strategies for efficient resource management and sustainable crop production in future Helps researchers interested in climate change impacts on the atmosphere, soil and plants

Water stress and heat stress are considered to be two primary factors that limit crop production in many parts of the world. Global warming appears to be increasing the water requirements of plants. Understanding the impact of water deficit on plant physiological processes and efficient water management are of great concern in maintaining food production to meet ever increasing world food demand. The book addresses various climatic soil and plant factors that contribute to the water use efficiency in plants subjected to water stress. It covers all issues related to soil, plant and climatic factors that contribute to the crop responses to water stress. The books advances the knowledge in improving and sustaining crop yields in ever increasing unpredictable climatic fluctuations This book uses crop simulation models for response of crops to limited water under various management and climatic conditions.

Climate change is a serious threat to field crop production and food security. It has negative effects on food, water, and energy security due to change in weather patterns and extreme events such as floods, droughts, and heat waves, all of which reduce crop productivity. Over six chapters, this book presents a comprehensive picture of the importance of agronomy as it relates to the United Nations’ Sustainable Development Goals. With an emphasis on the goals of Zero Hunger and Climate Change, this volume examines sustainable agronomic practices to increase crop productivity and improve environmental health.

Crop refers to any plant that is grown and harvested for subsistence or to earn a profit. Crops are generally harvested to function as food for humans or fodder for livestock. Agricultural, horticultural, floricultural and industrial crops are the primary categories of crop. Crop yield is defined as the quantity of the harvested crop per unit area of land along with its seed generation. Crop rotation, intercropping and multiple cropping are some common techniques for improving and increasing crop yield. Yield management is a pivotal part of optimizing revenue and profit from crop production. It is a complex process, which includes understanding revenue streams management, rate management and distribution channel management. This book explores all the important aspects of crop production and yield management in the present day scenario. It presents some path-breaking studies in this field. The extensive content of this book provides the readers with a thorough understanding of the subject.

A single seed is more than just the promise of a plant. In rural south India, seeds represent diverging paths toward a sustainable livelihood. Development programs and global agribusiness promote genetically modified seeds and organic certification as a path toward more sustainable cotton production, but these solutions mask a complex web of economic, social, political, and ecological issues that may have consequences as dire as death. In Cultivating Knowledge anthropologist Andrew Flachs shows how rural farmers come to plant genetically modified or certified organic cotton, sometimes during moments of agrarian crisis. Interweaving ethnographic detail, discussions of ecological knowledge, and deep history, Flachs uncovers the unintended consequences of new technologies, which offer great benefits to some—but at others’ expense. Flachs shows that farmers do not make simple cost-benefit analyses when evaluating new technologies and options. Their evaluation of development is a complex and shifting calculation of social meaning, performance, economics, and personal aspiration. Only by understanding this complicated nexus can we begin to understand sustainable agriculture. By comparing the experiences of farmers engaged with these mutually exclusive visions for the future of agriculture, Cultivating Knowledge investigates the human responses to global agrarian change. It illuminates the local impact of global changes: the slow, persistent dangers of pesticides, inequalities in rural life, the aspirations of people who grow fibers sent around the world, the place of ecological knowledge in modern agriculture, and even the complex threat of suicide. It all begins with a seed.
