The Effect of Phosphorus and Zinc Fertilizer on the Elements Concentration of Soybean Cultivars Seed Glycine max L

In order to evaluate the effect of phosphorus and zinc sulfate fertilizer on elements concentration of soybean cultivars an experiments was conducted in the north of Ghaemshahr in 2012. The factors examined included the factor A with three levels of phosphorus zero, 50 and 100 mg /kg from the source of triple superphosphate,factor B with three levels of zinc in concentrations of zero, 5, 10 mg/kg from the source of zinc sulfate and factor C of two soybean cultivars Telare BP, Sari (JK), respectively.The results showed that the highest phosphorus seed was achieved by taking 100 mg per kg (1.59) percent phosphorus and the consumption of 5 mg per kg of (1.57) percent zinc sulfate.There was also no statistical difference between JK and BP cultivar.By the effect of triple interaction between cultivar in phosphorus and zinc,the maximum amount of phosphorus seed in BP cultivar was achieved by the consumption of 100 mg/kg phosphorus and 5 mg/kg ,1.75% zinc and for the same cultivar by taking 100 mg/kg phosphorus and without using 1.73% zinc.The results showed that the amount of zinc seed in BP cultivar (104.9) microgr/gr was more than JK cultivar (97.9) Micro-g/gr that increased for 6.6% in comprison with JK. Also the results of the analysis of variance showed that phosphorus and zinc sulfate fertilizer and cultivar statistically had significant effect on all evaluated traits except nitrogen seed and protein seed. The results showed that seed oil content in JK cultivar in the treatment of non-application of phosphorus and zinc and the lowest amount of oil seed in BP cultivar in the reatment of 100 and 10 mg per kg phosphorus was obtained.In general, by using fertilizer and zinc sulfate in different cultivars can be caused changes in the concentration of seed quality and as well in some of the traits,the effect of phosphorus and zinc sulfate fertilizer were once had antagonistic relationship.
