Extensive long duration field and pot experimental data were used to extract and to set forth some regularities and rules governing the action of the plant growth factors and conditions in intensive crop production. The authors have formulated the rules of: - high yields as a result of the positive growth factors and interaction conditions; - sustaining or consequent inputs in intensive crop production; - restraining optimal domains of growth factor application in pace with yield increase; - pollution prevention in the crop production environment as a result of sustained nutrient uptake in plant; - improvement of soil physical, chemical and biological properties as a result of the positive growth interraction factor in increased crop production. Selected field and pot experimental data are presented to illustrate some practical consequences of these rules with respect to: - input decrease per yield unit as a result of the growth positive interraction factor; - fertilizer consumption decrease in pace per yield unit and soil nutrient suply increases; - nutrient uptake increase through physical improvement of plant environment, and - nutrient uptake increase and corresponding productive use of nutrients in yield through stimulation of metabolic processes in plants.
