ABSTRACT
Management requirements for achieving a moderate yield and average product quality require fewer inputs and skill requirements than are required for achieving maximum yield and highest product quality, the latter not allowing for errors in procedural practices. For most cropping situations, maximum biological yield potential based on the combination of soil and plant parameters is not known. It is also not possible to advance quickly from a moderate soil fertility/plant nutrition status to one that results in high yield/quality product achievement. Those management practices applied to one set of soil/plant/climatic conditions are not applicable to all ranges of conditions.
