Effect of Spraying with Marvel Nutrient and Antioxidants on the Mineral Content of Apricot leaves Labib Cultivar

Abstract

This study was carried out in one of the orchards of Kerbala city/Al-Hussainiya district. Where 30 apricot trees of Labib cultivar were selected, each tree was considered as an independent experimental unit with three replications. Foliar fertilizer by Marvel Nutrient solution at a concentration (0,2) ml/L was the first factor and the second factor was antioxidants which represented by ascorbic acid and citric acid at concentrations (500,1000) mg/L. for each tree. In addition, water was sprayed as the control application. The results showed that there was a significant effect for experimental treatments on the content apricot trees leaves of the mineral elements (Nitrogen, phosphorus, potassium, zinc and iron as the nutrient solution F2 and the antioxidant factor A2, S2 were superior. The interactions between factors F2*A2, F2* S2 (nutrient solution and antioxidants) was greater in giving the highest results levels of the content apricot trees leaves of the mineral elements (NPK, Fe and Zn).
