| The objectives were to investigate the relationship between the surface color characteristics of wheat grains and phosphorous and iron fertilizer rates. The treatments were a combination of four rates of phosphorus (0, 75, 150, and 225 kg ha-1) and three rates of foliar iron (0, 1.2, and 2 L ha-1) with three replications. The results of the study showed that some of the surface color values of wheat grains were depended on the phosphorous and foliar iron application rates; resulting in color shift toward the lighter regions. Phosphorus rates created higher variations than iron rates. With increasing the iron rate from 0 to 2 L ha-1, the average value of L* and color units increased significantly from 40.01 to 41.16, and from 1.56 to 3.33 respectively. No... |
