Impact of Nano-Micronutrients as Foliar Fertilization on Yield and Quality of Sugar Beet Roots.

BACKGROUND AND OBJECTIVE

Nanotechnology is one of the new technologies that entered almost all sides of our lives and were used in agriculture production. Nowadays, nanotechnology has expanded horizons in all fields of science. The study was aimed to investigate the response of yield and quality of sugar beet cv. Farida to foliar application of nano-microelements mixtures (Fe, Mn, Zn and B) with/without urea.

MATERIALS AND METHODS

Two field experiments were carried out in the experimental farm of the Etsa region in Fayoum Governorate, Egypt, during the two successive seasons (2015/16 and 2016/17). Fourteen treatments of four microelements as nano form sole and in combination with urea were applied and twelve traits were studied, growth traits, Juice quality traits and yield.

RESULTS

showed that the best results were found when sugar beet plants were treated with nano-microelements 200 mg L-1+ urea 1% and was ranked as the first favorable treatments for root length and diameter, dry matter per plant as root, top and sugar yields in both seasons, followed by the treatment of Nano-microelements 160 mg L-1+urea 1% for most of the traits studied. From the obtained results, Conclusion: it could be concluded that the application of nano-microelements 200 mg L-1+urea 1% treatment for significantly produced higher yields associated with improving the quality traits of sugar beet and saving the plants' needs from micronutrient and nitrogen fertilizers if this fertilizer rate has been added in the form of nanoparticles.
