effects of nano particle foliar application of iron nano on some morphophysiological traits of wheat (triticum aestivum l.), at shahr- e qods rejion

this experiment was done to evaluate the effect of nano iron oxide on some morphophysiological traits  of wheat (triticum aestivum l.) at  shahr-e qods region  in years of 2013 and 2014. experimental design, was factorial in a randomized complete block with four replications. treatments included, treatment of date of nano iron sparaying in milky  and pasty stage and another treatment was, concentrations of nano iron 0, 0.01, 0.02, 0.03 and 0.04 percent. traits that measured was 1000 grain weight,grain yield,gluten and amount of grain starch. the final results showed that, the effect of date of nano iron sparaying, was significant only on the gluten, starch, 1000 grain weight, grain yield while, of nano iron concentrations treatment, was significant on gluten, starch, 1000 grain weight, grain yield. interaction effect of date of sparaying and concentrations of nano iron oxide, was not significant on all characteristics. final results  showed that at effect of stages , maximum amount of grain yield,1000 grain wight,starch and gluten was obtained in milky stage.also results  from spraying with concentrations of nano iron oxide showed that maximum amount sof 1000 grain weight ,grain yield and gluten of grain obtained in 0/04 percent .while most amount of starch obtained in 0 concentraion.
