Response of wheat varieties, Triticum aestivum L., to spraying by iron nano-fertilizer

A field experiment was carried out in winter 2019 in the north of Basra Governorate to find response of four varieties of wheat (Baraka, Tammuz-2, Latifia and Ibaa-95) to different concentrations of iron nano-fertilizer (0, 1, 2 and 3 g L-1). The experiment was designed by applying factorial experiments using a randomized complete block design (RCBD) with three replications. This study revealed the superiority of variety Baraka in grain yield and biological yield, which reached 4.892 and 12.943 ton ha-1, respectively, as a result of its superiority in growth characteristics and yield components. Iron nano-fertilizer exhibited a significant impact on all studied traits, so that, 3 g L-1 displayed the highest average of grain yield (4.966 ton ha-1). Regarding to the interactions, the variety Baraka by spraying iron nan-fertilizer at 3 g L-1 exhibited the highest average of grain yield (5.800 ton ha-1) due to its superiority in yield components
