Çarşamba ve Bafra ovalarında seralarda yetiştirilen hıyar bitkisinin demir, bakır, çinko ve mangan beslenme durumunun belirlenmesi

Abstract

This study was conducted to evaluate the nutritional status and determine the nutritional problems of the cucumber grown under the greenhouse conditions in Çarşamba ve Bafra Regions. For this objective, from Çarşamba and Bafra region, 30 leaf samples and 60 soil samples (at the depth of 0-20 cm and 20-40 cm) were collected. In the soil samples texture, pH, CaCO3, total salt, organic matter, available P and K, DTPA+TEA extractable Fe, Cu, Zn and Mn, and in the leaf samples; total Fe, Cu, Zn and Mn analyses were conducted. Nutritional status of surveyed leaf and soils were evaluated by comparing the results of analyses with the interpretative values for the nutriens. According to experimental results, the soil pH of the experimental region was slightly alkaline and neutral. In regards to the majority of soil samples were highly calcareous, non-saline and slight to moderate salinity In regards to organic matter, the majority of soil samples were poor in humus content. The textures of soil samples, were clay loam and clay characteristics. The available phosphorus and potassium content were rich. The DTPA+TEA extractable iron, zinc, manganese and copper were at sufficient levels. Evaluation of the leaf analysis results show that the iron content of leaf samples was sufficient, zinc, manganese and copper contents were sufficient and high levels.
