The crop rotation plant is a decisive factor influencing the growth and development of wheat .The choice of an appropriate crop rotation of plants, for instance, maintains a normal C/N ratio of 40-70 (assimilative C versus assimilative N). Bacterial N fixation in the soil and a normal C/N ratio are conditions that offer the forerunner plant ameliorative properties [11]. The influence of plant cultivation technologies is expressed in the yield obtained per ha. The economic efficiency is quantified by the cost per ha or product unit. At present, this quantification is irrelevant due to the fact that products’ prices oscillate dramatically as a consequence of the inflation which is a characterisic of the present period. Thus, the most recommended method is to express the efficiency of the applied agrotechnical measures throught a different indicator, more stable and synthetic: KWh. This indicator is more realistic in respect to the investments and benefits of a cultivated crop and also makes possible the application of adequate measures leading to production increase per surface unit [1].
