The effects of different doses of humic acidapplication on yield and some quality criteria in strawberry

The research was conducted in a farmers' garden in the Dönüklü District of Onikişubat Province of Kahramanmaraş City and in the laboratories of Çukurova University Faculty of Agriculture Department of Horticulture and Kahramanmaraş Sütçü İmam University (Üskim) during the 2012-2013 growing period. In the experiment, it was observed that the fruit yield and some quality criteria and the macro and micro nutrients of the fruits in the doses of 0 ml / da (water), 200 ml / da, 400ml / da, 600 ml / da and 800 ml / da in Kabarla and Sweet Ann strawberry varieties effects on their contents were examined. It was observed that there was no effect on fruit weight, marketable fruit amount, TSS, titratable acidity, pH and sugars. It was observed that the applications had negative effects on yield value. It was observed that humic acid applications in the experiment area had different effects on plant nutrient concentrations in leaves. As a result of the applications, leaf N ‚ K ‚Mg‚ Cu and Mn amounts were positively affected, while‚ P, Ca, Fe and Zn values were negatively affected.
