Abstract

This study was undertaken during 2016 & 2017 seasons to examine the effect of using urea at 1 % with some vitamins (C & B1& B2& B6& B12) at 500 ppm on enhancing the uptake of these vitamins, growth, palm nutritional status, yield and fruit quality of Bartemuda date palms. The selected palms received three sprays at the first of March, May and July. Using urea at 1 % and / or vitamins (C & B complex) at 500 ppm was very effective in promoting growth aspects, palm nutritional status, yield and quality of fruits relative to the control. Using urea at 1 % alone was preferable than using vitamin C and/or B complex in enhancing all the parameters. Combined application of urea with these vitamins was substantially superior than using urea or vitamins singly. Three sprays of a mixture of urea at 1% besides vitamins C + B1+ B2+B6+B12 each at 500 ppm was responsible for improving yield and fruit quality of Bartemuda date palms. Results showed that vitamins must be applied with urea in date palm orchards.
