Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Agriculture - Department of Agricultural Biochemistry Summary: Application of nanofertilizers is one of the promising methods for increasing resources use efficiency and reducing environmental pollutions. This study was carried out to investigate the effects of lithovit (nano-CaCO₃), nano titanium dioxide (nano-TiO₂) and nano silicon dioxide (nano-SiO₂) on chemical constituents and yield characteristics of cotton plant under drought and normal conditions. The cotton plants pre-treated with four concentrations of nano-CaCO₃ (3000, 6000, 9000 and 11000 ppm), nano-TiO₂ (25, 50, 100 and 200 ppm) or nano-SiO₂ (400, 800, 1600 and 3200 ppm) then exposed to drought and normal conditions. In general, the drought stress reduced the pigments content, total soluble sugars content, glutathione reductase activity and yield characteristics, while increased total phenolics, total soluble proteins, total free amino acids, free proline content, total reducing power, total antioxidant capacity, catalase, peroxidase and superoxide dismutase activities in comparison with control. The obtained results showed that pretreatment of cotton plants under drought and normal conditions with nano-CaCO₃, nano-TiO₂ or nano-SiO₂ caused increasing of pigments content, total soluble sugars, total phenolics, total soluble proteins, total free amino acids, free proline content, total reducing power, total antioxidant capacity, antioxidant enzyme activities and enhancement of yield characteristics

Application of nanofertilizers is one of the promising methods for increasing resources use efficiency and reducing environmental pollutions. This study was carried out to investigate the effects of lithovit (nano-CaCO₃), nano titanium dioxide (nano-TiO₂) and nano silicon dioxide (nano-SiO₂) on chemical constituents and yield characteristics of cotton plant under drought and normal conditions. The cotton plants pre-treated with four concentrations of nano-CaCO₃ (3000, 6000, 9000 and 11000 ppm), nano-TiO₂ (25, 50, 100 and 200 ppm) or nano-SiO₂ (400, 800, 1600 and 3200 ppm) then exposed to drought and normal conditions. In general, the drought stress reduced the pigments content, total soluble sugars content, glutathione reductase activity and yield characteristics, while increased total phenolics, total soluble proteins, total free amino acids, free proline content, total reducing power, total antioxidant capacity, catalase, peroxidase and superoxide dismutase activities in comparison with control. The obtained results showed that pretreatment of cotton plants under drought and normal conditions with nano-CaCO₃, nano-TiO₂ or nano-SiO₂ caused increasing of pigments content, total soluble sugars, total phenolics, total soluble proteins, total free amino acids, free proline content, total reducing power, total antioxidant capacity, antioxidant enzyme activities and enhancement of yield characteristics
