Effect of Soil Applicatino and Spry Application Zinc on Chloriphyll Content, Anthocyanin and Wheat Grain Yield under Salinity Stress Levels

In order study the effect of soil application and zinc solubility on chlorophyll content, anthocyanin and grain yield of wheat under salinity conditions, an experiment was conducted in 2018 in a factorial based on a completely randomized block design with three replications in a research greenhouse of the Faculty of Agriculture and The natural resources of the University of Mohaghegh Ardebili were implemented. The investigated factors included soil salinity in four levels (control and salinity levels of 30, 60 and 90 mM in soil), sodium chloride salt and the second factor including zinc sulfate and zinc oxide (control), Soil fertilization, zinc sulfate, zinc dispersion and soil application and zinc solubility). The results showed that with soil application and solubilization of nanowahid and zinc sulfate in soil salinity, in comparison to non-zinc application in 90 millimolar salinity, grain yield, chlorophyll content a, b, total chlorophyll content, carotenoids (47.56, 65.2, 52.72, 62 and 50.43). Also zinc application in salinity conditions increased the content of anthocyanin. In general, the results of the research indicate the beneficial role of application of nanosilica and zinc sulfate in improving plant performance under salinity stress conditions.
