EFFECT OF SPRAYING SOME NUTRITIONAL SOLUTION AND SALICYLIC ACID ONSOME CHEMICAL CONTENTS OF MANDARIN SAPLINGS CLEMENTINE

Abstract

The Study was conducted at the Lath house horticulture department of and landscape design Agriculture College- Tikrit University during the period from March 2017 to May 2018 , to study the effect of spraying Disperchlorophyll, Salicylic acid and nutrition solution on some Chemical traits of Mandarin. Eighty one of 18 months old mandarin budded on sour orange rootstocks saplings were selected. Spraying on 1/3/2017 with Disperchlorophyll three concentrations(0, 150 and 300 mg.l-1) and Salicylic acid three concentrations (0, 100 and 200 mg.l-1) and nutrition solution three concentrations (0, 0.5 and 1 mg.l-1) The experiment planned based on factorial experiment on Randomized Complete Block Design (RCBD), with three replicates. The results were analysed using of SAS program and the means were compared using of LSD at probability of 0.05,The result showed: The spraying of saplings with Disperchlorophyll caused significant increasing in particular focus300mg.l-1 that exceed the rest of concentrations in leaves chemical continent of (Phosphor ,Potassium ،Carbohydrate،and C/N ratio) 0.1759%, 1.50%, 9.95%, 9.58% respectively, compared to without treated (no addition), which got lower than those values for the same characteristics.. The results showed that the treatment of spraying with Salicylic acid significantly, increasing of chemical continents (Potassium،Phosphor،Nitrogen Carbohydrate)(1.10%, 0.1726%, 1.47%, 9.08%, 6.87%) respectively,All those values compared to the without treated (no addition), which got lower than those values for the same characteristics. The effect of spraying nutrition solution was found superiority focus 1 mg.l-1 gave the highest the Nitrogen, Potassium ، Phosphor، Carbohydrate ،Protein، and C/N ratio (1.17%, 0.1763%, 1.45%, 9.81%, 7.31%, 8.87%( respectively ,All those values compared to the without treated (no addition), which got lower than those values for the same characteristics. Am on bilateral interactions and triple overlap there were significant differences as a result of these interactions.
