THE EFFECT OF TREATMENT WITH SUPER FIFTY PLANT NANO FERTILIZER AND POTASSIUM HUMATE ON THE CHEMICAL PROPERTIES OF THE LEAVES OF A VARIETY OF TISSUE ON DATE PALM, Phoenix dactylifera

This study was conducted in one of the private orchards in Basra governorate on date palm trees, which were classified as al-Khalas and al-Sagai, aged 6 years, and propagated by the method of tissue propagation, as 54 palm trees that were homogeneous in growth and size were selected as possible to conduct transactions on them. The experiment included three factors, the first type (al-Khalas and Sagai), and the second using three concentrations of super fifty agricultural fertilizers with concentrations (0, 1, and 1.5) ml. L-1. The third factor is the use of potassium humate added with irrigation water with concentrations (0, 3, 4) g. L-1 The transactions were added in three periods, the first before pollination on 2/15, the second period after a month from the first date 3/15 and the third period on 4/15 by 10 liter / palm tree. Paper samples were taken at the Khalal stage. The results of the study showed that the cultivar had a significant al-Khalas over al-Sagai variety, and it recorded the highest values ​​for all the studied traits except for the leaves content of the amino acid proline, as the variety recorded al-Khalas of the lowest value for the amount of proline, which amounted to 22.28 micrograms. Grams -1. As for the effect of the super plant Nano fertilizer, the treatment with the concentration (1.5 ml. L-1) significantly outperformed the remaining concentrations, and the highest value was recorded for the leaf content of nitrogen, phosphorus, potassium, total chlorophyll and carbohydrates (1.490%, 0.168%, 2.048%, 9.653 mg. 100 gm. -1, 49.44 mg.gm-1) respectively. Also, the interaction between the Super fifty nanoparticle fertilizer and the organic vegetable fertilizer potassium humate significantly affected the content of the leaves of nitrogen, phosphorous, potassium, total chlorophyll and carbohydrates, as the treatment recorded (1.5 ml. Liter -1 super + 4 g.L -1 humate) the highest values ​​(1.388%, 0.179. %, 2.282%, 11.697 mg. 100 g-1, 57.30 mg-1) respectively As for the triple overlap between the cultivar and the plant fertilizer, the Super fifty, and the organic plant fertilizer with potassium humate, the treatment was recorded (al-Sagai + 1.5 ml. L -1+ 4 g. L -1) The lowest value of the leaves content of proline was 13.82 μg.g.-1, with a significant difference from the rest of the interactions, while the triple-interference treatment (al-Sagai + 1.5 ml. L -1 + 4 g. L -1) recorded the highest value for the rest of the traits.
