Abstract

This investigation was carried out during both the 2018 and 2019 seasons to study the influence of the two investigated factors i.e., pomegranate cultivars (Manfalouty and Wonderful) and some nutrient solutions and their possible combinations on growth and nutritional status (leaf chlorophyll and mineral content). Data revealed that the Wonderful cultivar was better than Manfalouty cultivar in all vegetative growth measurements. Foliar spray with potassium citrate at 2.0g/ l. + Fe, Mn, and Zn at 100 ppm for each or potassium citrate at 2.0g/ l. + Fe, Mn, and Zn at 50 ppm for each was superior in this respect. The same treatments were it was able to increase leaf chlorophyll and mineral content as compared with the other different investigated treatments especially (control) during both seasons of study. Referring to the interaction effect of the two investigated factors on vegetative growth and nutritional status of pomegranate trees, data show the highest values were obtained with the combination between Wonderful cultivar and foliar spray with potassium citrate at 2.0g/ l. + Fe, Mn, and Zn at 100 ppm for each or potassium citrate at 2.0g/ l. + Fe, Mn, and Zn at 50 ppm for each.
