RESEARCHES REGARDING THE INFLUENCE OF FERTILIZATION ON THE YIELD AND ON THE OIL CONTENT OF THE SUNFLOWER PUBLISHED

Marius Bîte, Ioan Borcean
The paper presents the results obtained for two sunflower hybrids, Performer and Banat, cultivated on two fertilization levels, with phosphorus and potassium and on four levels of fertilization with nitrogen. The average yield for the fertilization levels of Banat hybrid was 13% higher than that of the Performer hybrid. By doubling the doses of phosphorus and potassium from P50K50 to P100K100a, there has been obtained an average yield for the nitrogen fertilization levels increased with 25%. The fertilizers having a content of nitrogen have favourably influenced the yield when applied in the researched field N0 - N100.
