Absztrakt

The present research deals with the relation for determining productivity elements based on differentiated
fertilization of wheat.
Ear length and spikelet number presented smaller variation amplitude, while grain number and the weight of
the grains on the ear had greater variation under the influence of differentiated fertilization. The differences
in the productivity elements under analysis have statistical assurance and high degree of certainty (p<0.01).
Generally, nitrogen had a higher contribution to the formation of productivity elements (R2 = 0.853 – 0.946)
than phosphorus and potassium (R2 = 0.449 – 0.723). Phosphorus and potassium played a more important
part in the formation of the number of grains than in the other productivity elements. It is possible to predict
with a high level of certainty (p<0.01) the productivity elements based on the doses of fertilizers applied.
Nitrogen allows of better prediction than the PK complex.
