"Plant Production on the Threshold of a New Century" describes and compares problems and frontier developments in the different sectors of plant production, integrating developments in basic plant sciences, crop science and socio-economic science, leading to sustainable plant production. Hence the book formulates goals and constraints in policy, economy, production, environment and land use; indicates how these goals and constraints may be translated into farming styles and cropping systems; and describes how the fundamental plant sciences can contribute to the implementation of such farming styles and cropping systems.
