effect of Foliar application with some Micro elements in growth and productivity of pomegranate tree

The research was conducted in Dara’a Governorate , Tafas area .where it rises 325 m above sea level, with an annual average of 325 mm of rain.The research was prepared for the 2019 - 2020 seasons.Where the research aims to study the effect of foliar spraying with some minorelements on the growth and productivity of the pomegranate tree.It also aims to study the effect of spraying treatments with some mineral elements onthe strength of tree growth.As well as the effect of "spray treatments" on the chemical composition and therole of spraying also with some mineral elements on the productivity of the fruits of thepomegranate tree.Where a randomized complete block design was used and the results wereentered into the Excel program according to transactions and replicates, and the data inall experiments were subjected to analysis of variance using the statistical analysisprogram.SPSS (Chicago 1993) according to the Fisher test) took the arithmetic mean ofthe different samples, and the tables and graphs were designed to study the differentsignificant differences, at the level of significance (95%).Where the following treatments and indicators were worked on: the averagelength of the annual parcels (cm), the average leaf area (cm2), the percentage of knots(%), the percentage of total soluble solids (when picking, the determination of the totalacidity that can be titrated at picking, the determination of the average weight of thefruit) g) from each treatment when harvesting (ZN, B, Mg, Ca, N, P, K) to determinethe average yield (tons / hectares) the content of the leaves from the elements.The content of the fruits of mineral elements when harvested (Zn, B, K, Mg,Ca).Where it was noted that the boron spray treatment of 1.5 g was superior to thecontract percentage (%) over all treatments including the control, where the percentageincrease at the highest value was 106.93% compared to the control 0.61%).While the zinc sulfate spray treatment in the average fruit weight (g) wassignificantly superior to all treatments including the control, the percentage increase was(327.77%) compared with the control (420g).While it was noticed that the zinc sulfate spraying treatment was superior to theproductivity of the pomegranate tree (ton/ha), where the percentage increase was(776.99%) compared to the control (6.21 tons).While the zinc sulfate spray treatment in the fruit juice content (%) wassignificantly superior to all treatments including the control, where the percentageincrease was (148.73%) compared to the control (19.7%).While the zinc sulfate spraying treatment in the fruits' vitamin content wassignificantly superior to all treatments, including the control, with an increase rate of(76.33%) compared with the control (13.1%).While the control spray treatment in the percentage of titrated acidity (%) wassignificantly superior to all treatments where the percentage of decrease was (58.74%)compared to the control where the highest acidity percentage in its fruits reached(1.89%).While the zinc sulfate spray treatment in the average leaf area cm2 wassignificantly superior to all treatments including the control, where the percentageincrease was (117.77) compared with the control (4.5 cm).
