Abstract
The experiment was carried out in one of the private orchards in the Saqlawiya sub-district of Fallujah district for the spring season 2021 to study the effect of foliar spraying with potassium silicate and Agri-fertilizer under the trade name IQ COMBI, which contains some microelements on some vegetative and chemical growth characteristics of the Apple cv. Ibrahimi. The spraying with potassium silicate included four levels (0, 1.5, 3, 4.5 ml. L-1) represents the first factor is symbolized by (S0, S1, S2 and S3) sequentially, while spraying with Agri-fertilizer IQ COMBI, represent the second factor included three levels its symbol is (Q0, Q1 and Q2) sequentially. The results can be summarized as follows: The foliar spraying with potassium silicate had a significant effect in improving the vegetative and chemical growth characteristics, as the level S2 gave the highest area per leaf of 32.13 cm2, while the level S3 gave the highest content of chlorophyll in leaves of 64.61 mg.100gm-1 fresh weight and highest content of carbohydrate in the branches was 9.73% compared to the level S0. The foliar spraying with Agri-fertilizer IQ COMBI had a significant effect on improving the vegetative growth and chemical characteristics, as Q2 gave the highest increase in the most studied traits. The interaction between the two factors of the study had a significant effect on all studied traits.
