Effect of time and concentration of nano-Fe foliar application on yield and yield components of wheat

The Effect of Foliar Application of ZnO Nanoparticles and ZnSO4 on Improving the Growth and Production of Durum Wheat

“…The figure shows a clear increase in the average grain productivity of wheat plants compared to the control ranged between 12 and 26 %, and an increase in the average produced straw ranging between 12 and 26 %, as well as an increase in the average weight of 1000 Kernel, which ranged between 3 and 9 %, The figure also shows that the addition of zinc oxide NPs by foliar application gave better results than Zinc sulphate and the tested productivity indicators values increased with increasing the concentration used up to 100 ppm (ZnO NPs). The reason is due to the role of nutrients in raising the efficiency of the photosynthesis process, as the number and weight of grain depends mainly on the rate of pollination and fertilization, thus increasing the activity of vital activities within the plant and improving growth indicators and photosynthesis and then transferring its products to the growing grains, because these grains after a period from its formation, it becomes the permanent downstream in annual plants, and that the bulk of the metabolites, whether newly formed or stored, lead to an increase in the grain weight and number during the fulling stage, which improves production indicators, and these results are agree with the findings of [20][21][22][23][24]. They obtained an increase in all wheat yield indicators by adding Nano fertilizers microelements, as they showed that the effective role played by the nanoparticles in increasing the vital and enzymatic reactions and due to the huge surface area, which leads to an increase in the speed of the reactions and the availability of an active carrier device that helps in the transfer of nutrients from the leaves to the grains, thus increasing the materials that reach the grains and thus increasing their weight and productivity.…”

Nano Fertilizers: New Vistas towards Sustainable Agriculture and Climate Change Mitigation: A Review

“…Kumar et al (2021) reported that the use of 50% N along with the foliar spraying of nano urea in rice at the tillering stage, nano zinc at 38 DAS and nano copper at 53 days after sowing significantly increased the grain and straw yield. Similarly, nano-Fe application at three different stages of crop growth (tillering, stem elongation and tillering + stem elongation) at 4% concentration resulted in a significant rise in the number of tillers per plant and seeds per spike in wheat (Armin et al, 2014). Reddy et al (2022) concluded that the combined application of 50% conventional urea and 50% N through nano urea along with nano Zn improves the grain yield and straw yield in Nano Fertilizers: New Vistas towards Sustainable Agriculture and Climate Change Mitigation: A Review maize.…”
