Abstract :
The purpose of this study was to determine the effects of nitrogen solution applications in hazelnutsucker management on yield and quality. This study was carried out at an orchard; established with thehedgerow system in Çarşamba district of Samsun province. „Çakıldak‟ cultivar was used in the study.Hazelnut suckers were removed by hand with a knife in March, 2016. About 1.5 months later, nitrogensolution applications were started when suckers reached 10-20 cm in length. Nitrogen solutionapplications were repeated four times from April to August, 2016. Doses of 0, 10, 15 and 20 % of thesolutions for both 21 % ammonium sulphate (AS) and 26 % calcium ammonium nitrate (CAN) wereapplied. To reveal the effects of this method on yield and quality, number of female flower clusters,number of clusters per shoot, number of nuts per cluster, nut weight, kernel weight, kernel ratio,thickness of the shell, good and wrinkled kernel ratios were determined. As a result of this study, suckermanagement with nitrogen solution applications positively affected the number of female flowers andnumber of clusters per shoot. On the other hand, this application didn‟t affect fruit quality.
