الملخص EN

The experiment was conducted at two locations (Aridisols and Entisols at Ninevah province) to study the effect of three levels of zinc (0, 5, 10) mg Zn .L-1 sprayed to the leaves of sugar beet and their interaction on the growth , nutrients uptake and quantity and quality of sugar beet (Beta vulgaris L.), by using randomized complete block design (R.C.B.D) with three replicates.

The results of this study showed that the use of higher levels sprayed with zinc caused a significant effect on yield quantity by increasing the total yield, yield per plant, weight per one root, and qualitatively (perx, sugar percentage, purity, raw sugar, pure sugar).

Higher response to fertilizer (Zn) application was found in the soil of compared Aridisols soil with Entisols soil, in the root yield quantity and quality (by increasing the total yield, sugar percentage, and sugar yield of sugar beet).

Also the fertilizer efficiency and inter needed of the elements were higher in Aridisols soil when compared with Entisols soil of at all levels of added Zinc fertilizers.
