Agronomic practices may need to be adjusted to maximize yield and quality of sugar beet. Thus agronomic package must be always modified. Nanotechnology is one of the new technologies that entered almost all sides of our lives and were used in agriculture production. Two field experiments will be carried out in the experimental farm of the Etsa region at El- Fayoum governorate, Egypt, during the two successive seasons 2015/16 and 2016/17 to investigate the response of yield and quality of sugar beet cv. Farida to foliar application of nano- microelements mixtures and or urea (Zn, Fe, B, Mn and N). Fourteen treatments were studied. | Effect of nano micronutrients and nitrogen foliar applications on sugar beet Beta vulgaris L. of quantity and quality traits in marginal soils in Egypt
