So why might it be necessary to consider . characteristics which are not visible, and why is it necessary to measure anything other than yield, which is, after all, the prime objective?

Introduction: World Population and Agricultural Productivity,, it is predicted that the human population will reach a distinct plateau (Salk and Salk 1981); these predictions are based on the change in populations in the more developed countries and analysis of animal populations. This plateau will occur at a value of between about 10 and 14 billion people (see Sadik 1990).
