EFFECTS OF FOLIAR APPLICATION OF ORGANIC AND GROWTH PROMOTER BIOZYME ON GROWTH OF WOLLY PEACH "RED JUNE" 2- leaves nutrients concentrations

Abstract

A Factorial experiment within Randomized Complete Block Design was coducted during 2014, 2015 on wolly peach seedlings C.V Red June, which grafted on the seeded apricot , at the Dept. of Horticulture – Coll. Of Agric. – Univ. of Baghdad. The objective of this experiment was to study the effect of foliar application The seedlings were sprayed with four levels of organic fertilizer Botryfun is 0, 3, 4 and 5( Ml.ltr^-1) for each level by the symbol F₀, F₁, F₂ and F₃ respectively, growth prpmoter Biozyme three levels are 0, 2 and 4(Ml.ltr^-1) are indicated G which is G₀, G₁ and G₂ respectively, recorded most of the treatment were significant differences for the control, were the highest values of organic fertilizer in the treatment of F₃ to all the elements reaching nitrogen 1.10 and 1.57 %, phosphorus 0.37 and 0.64%, potassium 2.16 and 2.66 %, iron 244.89 and 245.11 ppm, manganese 64.60 and 73.67 ppm, and zinc 105.33 and 128.67 ppm for two seasons respectively. And gave a growth promoter at the third focus G₂ highest rates in the stock content from the elements, as it gave the nitrogen 1.10 and 1.54%, phosphorus 0.37 and 0.49%, potassium 2.01 and 2.57%, manganese 61.33 and 72.67 ppm,  and zinc 100.00 and 127.67 ppm, except iron of both seasons. When overlap outperformed many treatment morally for the control were treated overlap G₂F₃ with the highest value for all nutrients studied, which amounted to 1.12 and 1.70% nitrogen, 0.43 and 0.50.% Phosphorus, 2.22 and 2.78% potassium, 241.67 and 242.00 ppm iron , 68.00 and 86.67 ppm, manganese 121.67 and 132.00 ppm zinc. while the control recorded lower values and all the nutrients studied.
