To evaluate the effect of sowing and levels of phosphorus on the absorption of iron and zinc in agricultural experimental farm 2014-13 Agricultural and Natural Resources University, Ahvaz Ramin implemented The experiment was split plot in a randomized complete block design with four replications. The experiment consisted of five sowing dates (2 October, 17 October, 1 November, 16 November, 1 December) in the main plots and fertilizer phosphorus oxide (p2o5) levels (0, 50, 100, 150 kg ha) Triple superphosphate was considered the source of the sub-plot Results showed that sowing date had no significant effect on seed concentration on the fertilizer effect was significant. The results showed that phosphorus application and sowing date had a significant effect on iron concentration in the grain. This is the interaction was significant. The results of cutting table treatments, the amount of phosphorus in the plant on 10 November on seed iron concentration was significant The mean interaction effect of planting date indicate that P and P application
most significant has been the history of planting 10 November
