In this study, copper content of soil and irrigation water and copper content of leaves and grain of wheat (Triticum spp.) were studied. Study samples of soil, leaf and grain were collected from wheat (Triticum spp.) fields in Cukurova Region of Turkey. Soil samples taken from the root area of plants where the leaf and grain samples were collected and analyzed for copper (Cu) content. The leaf samples taken during the stem elongation and the grain samples taken at the time of maturation were also analyzed for Cu content. The correlation analysis between soil-Cu contents and leaf and grain-Cu contents was performed to determine the relationships among the variables. The Cu content of the soil samples collected in 2005 was between 0.78 and 1.56 mg kg-1. The Cu content of the soil samples collected in 2006 was between 1.12 and 1.96 mg kg-1. The copper content of the majority of soil samples, collected in 2005 was observed above the critical level which is 1 mg kg-1. The Cu content of the leaf samples was ranged from 26.30 to 67.60 mg kg-1 in 2005 and 3.06 to 18.02 mg kg-1 in 2006, whereas the copper content of the grain samples was ranged from 11.77 to 17.89 mg kg-1 in 2005 and 7.37 to 14.06 mg kg-1 in 2006. According to data analysis performed in collected samples, the Cu content of the leaf and grain samples was directly correlated with the Cu content of the soil. Correlation between copper content of soil and copper content of leaf in 2006 are significant at the 0.01 level based on the statistical analysis. Also, correlation between copper content of soil and weight of 1000 grain in 2005 and in 2006 are significant at the 0.01 level in respect of statistical analysis. |

Morphological, chemical and some mineralogical characteristics of five soils, were researched to understand the genesis of soils on the man made mounds in the Harran Plain, in the Southeast Anatolia Region of Turkey. Five soil profiles developed on the man made mounds in the arid region. Time and climate have affected soil formation. Also, parent material has influenced the chemistry of soils. The parent material of man made mounds were carried from around soils in the Harran Plain by men in years ago. The parent materials of around soils are calcareous parent materials and alluvium materials. Pedon 1 was described on the Konuklu man made mounds the northeast of the study area and Pedon 5 was described on the Kupluce man made mounds the southeast of the study area. According to the place of man made mounds were ordered from north to south as following: Pedon 1, Pedon 2, Pedon 3, Pedon 4 and Pedon 5. The old of Konuklu mounds is approximately 5000-6000 years. The old of Sultantepe and Koruklu mounds are approximately 6000 years. Pedon 4 which was described on the old Harran city remnants have the youngest soils of study area. The Harran mounds was made in 1258 A.I. by Mongolians. Mongolians destroyed the Harran City and made the Harran mounds. The most important pedogenic processes is carbonate leaching and accumulation in the pedon 5 on the Kupluce man made mounds. The CaCO3 content of Pedon 5 may be attributed to eolian addition from Syria. Total Al2O3 contents of soils higher than total Fe2O3 content. According to the degree of soil formation the profiles were ordered as following: Pedon 3>Pedon 5>Pedon 2> Pedon 1>Pedon 4. The results of total elements analysis were used to determine the β leaching factor according to Jenny. The leaching factor were determined as < 1 in the Pedon 1 (0.99), Pedon 2 (0.97), Pedon 3 (0.74) and Pedon 5 (0.92). The leaching factor were determined as >1 in the Pedon 4 (1.13). |

Background and Objective: Selenium (Se) is an essential plant micronutrient and has been repetedly shown to enhance crop growth
and crop tolerance to abiotic stresses when applied in trace amounts. However, physiological responses of different plants vary
significantly to the Se fertilizer application. The aim of this study was to investigate the effect of Se application on yield and quality
parameters of peanut under field conditions. Materials and Methods: A pot experiment was conducted where Se fertilizer was applied
(i) To soil at 5 different doses, (ii) As folier fertilizer or (iii) Via seed soaking at 4 different doses. Two years field experiments were conducted
under East Mediterranean conditions of Turkey. Results: The yields were significantly increased by all types of Se applications. The highest
yield (6130 kg ha–1) was obtained from foliar applications made 40 days after flowering. Increasing doses of Se increased 100 grain weight
but oil, protein and nitrogen content of grains were not affected. Conclusion: Two years experiment clearly showed that external Se
supply to peanut (all methods tested) increased yield formation in East Mediterranean conditions of Turkey. Here, particularly foliar
application (3% sodium selenite) of Se 40 after flowering seems to be most effective way for its application. |
