A field experiment was conducted at Mallawi Agriculture Research Station Farm –(latitude of 27.73 o 28? N and longitude of 30.83o 95? E) El-Minia Governorate, Egypt in two successive seasons of 2016/2017 and 2017/2018 to find out the influence of nitrogen fertilization and Titanium dioxide nanoparticles TiO2 on yield and quality of three sugar beet varieties. Varieties exhibited significant differences in root length and sugar recovery in the two growing seasons, whereas the differences in TSS% were not significant. The differences among varieties in pol% and sugar yield were significant only in the second and the first growing season, respectively. Nitrogen fertilization had significant effects on root length, pol%, sugar recovery and sugar yield in both seasons, meanwhile it has a significant effect on TSS% only in the first season. TiO2NP concentrations had significant effects on root length, pol%, sugar recovery and sugar yield in the two growing seasons, meanwhile it has insignificant effect on TSS% in both seasons. The second order interaction had insignificant effect on root length, TSS% and sugar yield in both seasons, meanwhile it has significant effects on pol% and sugar yield in the two growing seasons. Under conditions of the present work, it is recommend to fertilization Hercule or Kawemira sugar beet varieties by 60 or 80 kg N/fed. and 300 or 200 ppm TiO2NP to produce the best quality as well as the highest sugar yield/fed. |
