Agricultural science involves the integrative study of various aspects of agriculture including crop production, economic impact, soil fertility and sustainability. This book discusses important areas in agricultural science, such as crop enhancement, production, response to water, nutrients, and temperature, crop protection, agriculture and human health, and animal nutrition. The topics discussed by the authors involve manipulation of the variables and genetic resources of inheritance of quantitative genes, crop rotation, soil water and nitrogen, and impact of temperature on flowering. Other topics covered include safeguarding crops against insect pests and diseases, associating agriculture topography to recreation by humans, and small ruminant nutrition. This book will be a worthy addition to existing knowledge database and will be particularly useful for university students and professionals in the field of agriculture.
