Abstract
A field experiment was Conducted at Horticulture Station in Hindya city /Kerbla’a Governorate during the fall Season of 2011-2012. The experiment aimed to Study the effect of application of levels of chelated iron Fe-EDDHA (0, 8, 16, 24) Kg h-1 at three levels of phosphorous application (0, 80, 160) Kg ha-1 P2O5 in growth, grain yield and uptake of iron and zinc of wheat plant Al-Rasheed variety. A randomized complete block design was used with three replications. Means were compared using LSD test at 0.05 probability. The results revealed that application of chelated iron led to a significant increasing in iron content of leaves. The high level of iron application (Fe3) gave the highest value (92.45) mg Kg-1. Similarly the highest level of phosphorous application (P2) gave the highest value of phosphorous in leaves (0.59%) Comparing with values of (43.18mg Kg-1) and (0.32%) for control treatment for iron and phosphorous, respectively. The best interaction appeared to be the (P2Fe3) treatment. With respect to seed content of iron and phosphorous showed a significant increase also; the highest values were observed at (Fe3) for iron and at (P2) for phosphorous and they were (68.92) mg Kg-1 and (0.59%), respectively. The zinc content of leaves and seeds showed a significant decline as iron and phosphorous application increased in other words application of iron and phosphorous aggravated zinc deficiency in wheat plants under these conditions. The lowest value obtained for zinc content was for (P2Fe3) treatment (20.06) mg Kg-1 whereas it was (30.01) mg Kg-1 for P0Fe0 treatment. Increasing availability of iron and phosphorous due to their application to the soil led to increase plant height, Spikes number, 1000 grain weight and grain yield significantly.
