Abstract
Afield experiment was conducted at Abou El Ghar village, Kafr El Zayyat district, Gharbiya Governorate, Egypt during 2016- 2017 and 2017-2018 seasons. The aim of this study to evaluate the influence of bulk and nanoparticles zinc oxide on growth and some biochemical characteristics of sugar beet (Beta vulgaris L.). The experiment was laid aut using strip-plot design with three replications. zinc oxide concentrations (control, 100, 200, 300 ppm) were arranged horizontally while nitrogen fertilizer (60, 80 and 100 Kg N/fed). Was allocated vertically.
 
The main results could be summarized as follows:
 

foliar spray of nanoparticles zinc oxide had a significant effect on root fresh weight/plant, root yield, gross sugar yield, sucrose %, and recoverable sugar % in both seasons. As well as, had a significant effect on root/top ratio, in the second season only and had a significant effect on recoverable sugar yield in the first season only.
The best concentration of nanoparticles zinc oxide for sugar beet was 300 ppm with the highest root and sugar yields.
Increasing nitrogen rates from 60 to 100 kg N/fed. significantly increased the most studied characters under study such as, root fresh weight/plant, top fresh weight/plant in the second season also, sugar beet yields (root and top) as well as sugar losses in molasses. On the other direction, quality parameters such as sucrose %, purity, quality index significantly decreased by increasing nitrogen levels as nitrogen level increased. Moreover, root/ top ratio and harvest index decreased as nitrogen level increased.
It could be concluded that nitrogen fertilizer level at 100 Kg N/fed. and foliar sprayed zinc oxide nanoparticles at a concentration of 300 ppm is a recommended treatment for maximizing sugar beet yield. Otherwise, fertilization sugar beet plants by 60 kg N/fed. with 200 ppm produced the highest mean values of studied quality traits.
