Book Description
The objective of this book is to provide information to be used as a basis for evaluating the fragile, shaky structure of global food production. The volume analyses the data by region and by intensity of cultivation; and furnishes information about the yield response, giving some indication of the health of the plants. It will be invaluable to all plant and crop scientists as well as to agriculturalists.

Book Description
Agricultural crops are prominent features of an increasing number of variously perturbed ecosystems and the landscapes occupied by these ecosystems. Yet the ecology of agricultural-dominated landscapes is only now receiving the scientific attention it has long deserved. This attention has been stimulated by the realization that all agriculture must become sustainable year after year while leaving nearby ecosystems unaffected. Ecology in Agriculture focuses exclusively on the ecology of agricultural ecosystems. The book is divided into four major sections. An introduction establishes the unique ties between agricultural and ecological sciences. The second section describes the community ecology of these sorts of ecosystems, while the final section focuses on the processes that operate throughout these agricultural landscapes. - Contains an ecological perspective on agricultural production and resource utilization - Includes in-depth reviews of major issues in crop ecology by active researchers - Covers a range of topics in agricultural ecophysiology, community ecology, and ecosystems ecology - Provides examples of ecological approaches to solving problems in crop management and environmental quality

Book Description
This book presents principles and practices for ecologically based weed management in a wide range of temperate and tropical farming systems. Special attention is given to the evolutionary challenges that weeds pose and the roles that farmers can play in the development of new weed-management strategies.

Book Description
Weeds hold an enigmatic and sometimes-controversial place in agriculture, where they are generally reviled, grudgingly tolerated, and occasionally admired. In most cases, growers make considerable effort to reduce the negative economic impact of weeds because they compete with crops for resources and hinder field operations, thereby affecting crop productivity and quality, and ultimately the sustainability of agriculture. Weed control in production agriculture is commonly achieved through the integration of chemical, biological, and mechanical management methods. Chemicals (herbicides) usually inhibit the growth and establishment of weed plants by interfering with various physiological and biochemical pathways. Biological methods include crop competition, smother crops, rotation crops, and allelopathy, as well as specific insect predators and plant pathogens. Mechanical methods encompass an array of tools from short handled hoes to sophisticated video-guided robotic machines. Integrating these technologies, in order to relieve the negative impacts of weeds on crop production in a way that allows growers to optimize profits and preserve human health and the environment, is the science of weed management.
