Abstract

Experiment was carried out throughout two successive seasons of 2016 and 2017 on Manfalouty pomegranate trees grown at the Experimental Orchard of Assiut University, Faculty of Agriculture. Thirty six uniform trees (9 treatments x 4 replications) were chosen. The spraying treatments were: Micronutrients at the concentration of 2.5 and 5%, amino acid mixture at 1 and 2%, and Potassium solution at 1.5 and 3% and calcium solution at 2.5 and 5%. The obtained results revealed that most of the treatments increased total yield weight. The most effective treatments were micronutrients at 5%; amino acids at 2% and potassium. All the treatments significantly decreased fruit cracking comparing with the control. The most effective treatments were calcium and potassium spraying. The present data also suggested that spraying with micronutrients and amino acids at 1% produced the best fruit quality. From the obtained results of the present study it could be recommended that: Spraying micronutrients and amino acids for obtaining the best fruit quality with reasonable yield and healthy fruits. For decreasing the fruit cracking and increase the fruit firmness it could be recommended that to spray the fruit with calcium and potassium.
