The Effects of Micronutrients (Fe And Zn) and Beneficial Nano-Scaled Elements (Si And Ti) on Some Morphophysiological Characteristics of Oilseed Rape Hybrids

Current experiment was conducted to investigate the effects of foliar application of different nutrients (control, nano-chelated Fe, nano-chelated Zn, nano-TiO₂, nano-Si) on seed yield and morpho-physiological characteristics of oilseed rape cultivars (Hydromel, Neptune, Nathalie, Danube, Alonso). The highest pod numbers was achieved by foliar application of Zn and nano-SiO₂ in cv. Hydromel and Neptune. The heaviest seeds were recorded for plants treated with nano-SiO₂. The highest seed yield was recorded for cv. Hydromel and Neptune treated with Fe and nano-TiO₂. The highest indole acetic acid was recorded in cv. Hydromel treated with Zn and nano-SiO₂. The evaluation of plant pigments revealed that foliar application of nano-SiO₂ and TiO₂ significantly increased the concentration of carotenoids and Chlorophyll a, b. Overall, the results indicate that cultivating the high yielding hybrids (Hydromel, Neptune, Nathalie) along with the application of iron, SiO₂ and TiO₂ nano-particles can greatly improve plant performance
