A field experiment was carried out during 2017 and 2018 seasons at the Agronomy Department Experimental Farm, Agriculture Faculty, Assiut University to study the effect of foliar spray time by different zinc oxide nanoparticles concentrations (ZnO NPs) on production of maize. The experiment was laid out in randomized complete block design (RCBD) using strip plot arrangement with three replications. Zinc oxide nanoparticles concentration (tap water without ZnO NPs (control), 100, 200 and 300 ppm) were allocated horizontally, while, application time (8-10 leaves, tasseling and grain filling stages) were arranged vertically. Results show that zinc oxide nanoparticles concentrations did not affected significantly on all the studied traits in the both seasons, Furthermore, the foliar spray time had a significant effect on grain yield fed .-1 in the both season, grains weight plant in the first season only and number of grains row-1 in the second season only. Moreover, the interaction between studied zinc nanoparticles concentrations and applications time in this respect failed to be significant at 5% level of probability in the two growing seasons. Whatever, the highest grain yield fed.-1 mean value in the first season (3090.00 kg) was recorded from maize plants which were sprayed by 100 ppm of zinc oxide nanoparticles (ZnO NPs) at tasseling stage, while the corresponding mean value in the second season (3846.00 kg) was achieved from maize plants which were sprayed by 200 ppm zinc oxide nanoparticles at 8-10 leaves stage.

A field experiment was carried out during 2017/18 and 2018/19 seasons at the Agronomy Department Experimental Farm, Agriculture Faculty, Assiut University, to study the effect of foliar spray by some Nano micro-nutrients on production of three bread wheat cultivars. The experiment was laid out in randomized complete block design (RCBD) using strip plot arrangement with three replications. Foliar spray with tap water (solvent as a control) and Foliar spray with Fe, Mn, Zn, Fe+Mn, Fe+Zn, Mn+Zn and Fe+Mn+Zn in Nano form at 200 ppm were allocated horizontally, while bread wheat cultivars (Sids-1, Sids-12 and Gemmeaza-11) were arranged vertically. The obtained results show that the foliar spray treatment by some micro-nutrients Nano-particles had a significant effect on plant height, kernels number spike-1 , 1000 kernel weight, kernel weight spike-1 and grain yield in both seasons. Thus, wheat plants which were sprayed by Fe+Mn+Zn produced the highest mean values of the most previous traits. Furthermore the studied cultivars had a significant effect on all studied traits. In addition, Gemmeaza-11 cultivar produced the highest mean values of most studied traits in the two growing seasons. Here too, the interaction between some micro-nutrients Nano-particles and bread wheat cultivars had a highly significant (P ≤ 0.01) and significant (P ≤ 0.05) influence on grain yield in the first and second seasons respectively. Thus, the highest mean values of grain yield (26.80 and 26.95 ardab fed.-1 in the tow respective seasons) were obtained from Gemmeaza-11 cultivar which was sprayed by Fe+Mn+Zn Nano-particles in both seasons.

The present study is carried out to establish the biofortification of zinc in potato (Solanum tuberosum L.) and tomato (Solanum lycopersicum L.) plants through the application of zinc oxide nanoparticles (ZnONPs). The mycogenic ZnONPs are synthesized by using Aspergillus flavus biomass and characterized to ascertain the size, shape, and concentration of synthesized nanoparticles. The ZnONPs are applied by foliar spray to the field-grown potato and tomato crops and the biofortification level is recorded by Atomic Absorption Spectroscopy (AAS). A nanotoxicity assessment is done by comparing the amount of cell death and accumulation of reactive oxygen species (ROS) in control and ZnONPs treated plants. The AAS analysis reveals significant accumulation of the zinc in leaves of potato plants but insignificant accumulation is observed in the tubers. However, a significant accumulation of zinc is observed in the leaves and fruits of the tomato plants (p ≤ 0.05). The nanotoxicity evaluation studies show comparable and statistically insignificant toxicity in control plants as compared to plants treated with ZnONPs. The study concludes that biofortification through the means of ZnONPs is a cost-effective and eco-friendly approach that can be used as an alternative to the hazardous chemical zinc fertilizers.
