Effect of some nutrients and amino acids spraying on yield and fruit quality of Manfalouty pomegranate [electronic resource]

Includes bibliographic reference

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.
