In this study, the effects of zinc application on copper contents of leaf and grain of two peanut varieties were investigated in the Çukurova Region in Turkey. Also correlation between copper content of soil and copper content of peanut plant were investigated in the study. The copper contents of soil samples collected from each experimental plot of NC-7 variety changed between 0.78 mg kg-1 and 0.96 mg kg-1 in 2006. The copper contents of soil samples of experimental plot of ÇOM variety ranged from 1.50 mg kg-1 and 1.86 mg kg-1. While copper contents of soil samples of experimental plot of ÇOM variety were higher than 1.00 mg kg-1 which critical level for a lot of plants, the copper contents of soil samples of experimental plot of NC-7 variety were lower than 1.00 mg kg-1. While the copper content of grain samples of NC-7 variety are changed between 8.00 mg kg-1 and 16.00 mg kg-1, the copper content of grain samples of ÇOM variety are changed between 11.00 mg kg-1 and 18.00 mg kg-1 in 2006. While the copper contents of soil samples collected from each experimental plot of NC-7 variety changed between 1.10 mg kg-1 and 1.40 mg kg-1, the copper contents of soil samples of ÇOM variety ranged from 0.90 mg kg-1 to 1.34 mg kg-1 in 2007. While there are positive correlation between copper content of soil and copper content of grain of NC-7 variety, there are negative correlation between copper content of soil and copper content of leaf in 2006 and 2007. Also, there is positive correlation between copper content of soil and copper content of leaf of ÇOM variety, there are negative correlation between copper content of soil and copper content of grain in each years. Also there is negative correlation between copper content of leaf of ÇOM variety and P contents of grain in 2007. This correlation was statistically significant (P<0.01). While there are positive correlation between dozes of Zn application and contents of leaf and grain of NC-7 variety, there negative correlation between Zn application and contents of leaf and grain of ÇOM variety in 2006. But this correlation was statistically insignificant. The negative correlation between dozes of Zn application and contents of leaf of ÇOM variety was statistically 0.05 level significant in 2007.

In this study, the effects of Fe application on Cu and Mn contents of soil, leaves and grain of peanut were investigated. This experiment was established in 2006 and 2007, four different doses of iron (0, 10, 20 and 40 kg ha -1) were applied to soil. Foliar applications of iron at the doses of 0, 1, 2 and 3 kg ha -1 were applied following the flowering period of twenty days. The copper contents of soil samples collected in 2006 ranged from 0.60 to 1.66 mg kg -1 and those of samples collected in 2007 from 0.96 to 1.46 mg kg -1. The copper contents of the majority soil samples collected in 2006 and 2007 were above the critical level which is 1.00 mg kg -1. The copper content of leaf samples in 2006 ranged from 2.00 to 8.00 mg kg -1 and in 2007 from 2.10 to 4.40 mg kg -1. The copper contents of grain samples in 2006 were between 7.00 and 15.00 mg kg -1 and in 2007 were high and ranged between 12.65 and 60.68 mg kg -1. There is negative correlation between Fe application trial and Cu contents of plants (leaf and grain samples) collected in 2006 and 2007. Correlation between Fe application trial and Cu contents of leaf and grain samples were significant at the 0.05 level. Source
