The study was conducted to investigate the wheat yield affected by different concentrations of chemical Potassium (K) (0, 25%= 28.6, 75%= 85.7 and 100%= 118.0 kg K ha −1 recommended rate, KRR), with and without the application of foliar spraying of feldspar nanoparticles solution and different iron treatments (using foliar spraying of 0.3% twice from ferrous sulphate, or natural hematite nanoparticles). Two field experiments were conducted at two different locations; the first was at the Agricultural farm of Sids Agricultural Research Station (ARC), and the second was at a private farm at Sids village in 2018/2019 season. Grain, straw and biological yields, nitrogen content, protein content, and protein yield were determined. Results showed that increasing K levels up to 118.0 kg K ha −1 increased grain, straw, biological yields nitrogen, protein content, and protein yield. Foliar spraying of feldspar nanoparticles or ferrous sulphate or hematite nanoparticles enhanced all the above-mentioned parameters. Combined 75% KRR with feldspar nanoparticles showed yields and quality of wheat equal to those under 100% KRR. Foliar spraying of hematite nanoparticles has equal effect on wheat productivity as ferrous sulphate. The highest wheat yields and protein characteristics were achieved for the treatment of 100% KRR or 75% KRR with foliar spraying of feldspar nanoparticles and foliar spraying of ferrous sulphate or hematite nanoparticles. To conclude; the study revealed the possibility of saving about 25% KRR by foliar spraying of natural feldspar nanoparticles, and using hematite (iron oxide) nanoparticles instead of ferrous sulphate.
