The objective of the present work was to compare the efficiencyof systematic use of different rates of nitrogen, phosphorus and potassium fertilizers and nutrient rates in the prevailing according to the amounts of nutrient soil for the major agricultural plants in the field crop rotation, by assessing the effect of fertilizers on agricultural crop yield, chemical composition and balance of nutrients. The tests were carried out over the period 1971-1997 on a sod-gleyic light loam soil whose arable horizon was of neutral reaction, containing medium amount of humus, low of available phosphorus and medium amount of available potassium
