Effect of pollinator cultivars on nutrient content in some Turkish hazelnut cultivars

Abstract

The main objective of this study was to assess the pollen effects on macro and micro nutrition elements on hazelnut cultivars (Corylus avellana L.). Tombul, Palaz, Çakıldak, Foşa and Allahverdi were used as main cultivars while Tombul, Palaz, Çakıldak, Foşa, Allahverdi, Sivri, Kalınkara and Yassı Badem were used as pollinator cultivars. In the study, it was investigated that the pollinator cultivars caused changes in some nutrition elements. The effects of the applications on nitrogen, phosphorus and potassium content were found to be statistically significant. It was determined that the nutrition element with the highest rate in the examined hazelnut cultivars is potassium. It has been observed that the amount of potassium is high in Tombul-pollinator treatments. The potassium content of Foşa and Çakıldak weres found to be higher than other cultivars. In Palaz and Yassı Badem- pollination treatments, it has been observed that the Ca content is generally lower than other treatments. Fe content was found to be significantly higher in Palaz-pollination treatments. The highest Mn and Zn content was obtained from Çakıldak. As a result, it has been revealed that pollinators may have an effect on nutrient content.
