Abstract
This study was carried out during 2013 and 2014 seasons to test the effect of single and combined applications of NPK each at 0.1%, Zn Fe Mn each at 0.05% and citric acid at 0.1% on growth characters, tree nutritional status, yield and fruit quality of Washington Navel orange trees.Single and combined application of different nutrients and citric acid was effective in enhancing all growth characters, leaf nutrient content, yield and fruit quality over the control treatment. Using macro and micro nutrients was superior than using citric acid in this respect. All nutrients and citric acid together was preferable than using each alone in this connection.Treating Washington Navel orange trees three times at growth start, just after fruit setting and at one month later with a mixture of NPK each at 0.1% , Zn Fe Un each at 0.05% and citric acid at 0.1% was responsible for promoting yield and fruit quality.
