| Abstract | ||
| The study aims to investigate the effect of different levels of phosphate fertilizer on the response of wheat( Triticum aestivum L.) to foliar application of iron and zinc in gypsiferous soil . A field experiment was conducted during the season 2009-2010 to grow wheat. The experiment was designed as afactorial experiment with split-split block design with three replications. Phosphorus levels was the main plot and wheat varieties was subplot and finally the treatments of iron and zinc were sub –subplot . phosphate fertilizer was applied at four levels 0, 86, 172 ,258 (kg P.ha-1) as triple superphosphate(21%p)before planting Wheat varieties( IPA 99) and (Abu- Gharib-3) were used in this experiments. Iron was added at three levels 0,50,100 (mg Fe . L-1 ) as ferrous sulphate while zinc was added 0,25,50( mg Zn .L-1 ) as zinc sulphate and their compinations were nine treatmens as follows: ,Fe0Zn1,Fe0Zn2,Fe1Zn0,Fe1Zn1,Fe1Zn2,Fe2Zn0,Fe2Zn1,Fe2Zn2. Zn0 Fe0 Iron and Zinc were applied as foliar application at Tillering and booting stages of plant growth.Results induicated that application of phosphate Iron and zinc fertilizers significantly increased dry weight and uptake phosphorus, iron and zinc .High level of Phosphate fertilizer decreased the dry weight and Phosphorus iron and zinc uptake . Abu-Grhaib-3 Varitey was more susceptible to application of iron and zinc at P0 level than IPA99 varitey. IPA99 variety was superior in dry weight yield and iron and zinc uptake compared with Abu-Ghraib variety. Treatment of Fe1Zn1-P2 of IPA99 gave the highest uptake of iron 194.90mg. plant-1 while the treatment Fe2 Zn0-P2 of Abu-Gharib-3 variety gave 190.61 mg-plant-1. Treatmrnt Fe0Zn2-P2 of IPA99 gave the the highest value of zinc 76.79mg. plant-1 , while at Abo-Gharib-3 treatmentofFe0Zn1-P1 gave 61.77 mg,plant-1. . | ||
