1) Principles of Ecology in Plants Production.(CABI, 1998)
By T.R Sinclair & F.P. Gardner
The dramatic increases in population and living standards during the twentieth century have led to serious concerns over the sustainability and environmental impact of modern agriculture. This textbook will enable students from a broad range of backgrounds to gain a basic scientific understanding of the processes which define the ecology of plant production. The book begins with a consideration of global issues. This is followed by a series of chapters on the relationship between plant production and the environment; topics include ecological principles, the importance of genetic manipulation and diversity, historical development of agricultural ecosystems and yield increases, biophysical limits of productivity, the soil-plant relationship, and water requirements. The second section then considers the physical environment that influences plant production; it examines the effects of solar radiation, temperature, weather, and atmospheric gases. This book is essential reading for students of agronomy, plant science, ecology and environmental biology and for others with an interest in the sustainability of plant production and its associated environmental considerations.
2) Crop Ecology: Productivity and Management in Agricultural System.(Cambridge University Press, 1992)
By R.S. Loomis & D.J. Connor
This book is centered on the "production processes" of crops and pastures, photosynthesis, and use of water and nutrients in fields. It is unique in its combination of great breadth and depth in its treatment of production processes and systems problems. The approach is explanatory and integrative, with a firm basis in environmental physics, soils, physiology, and morphology, in contrast to descriptive or reductionist approaches. Systems concepts are introduced early and expanded as the book proceeds, giving emphasis to quantitative approaches, to management strategies and tactics employed by farmers, and to environmental issues. The systems approach is brought together in the final chapters where production and nutrient cycling are analyzed, for example farms and problems in an uncertain future are considered. The book is designed for use as a text for an introductory course in crop ecology (advanced undergraduates and beginning post-graduate level). In addition, given the wide range of subjects, the integrated references, and the background material included, it can also be considered a "stand-alone" reference work useful to agriculturalists and botanists.
