Determination of nutritional status of pistachio orchards in Adiyaman region

In this study, samples were taken from 30 orchards in total in order to determine the nutritional status of 5 farmers' pistachio orchards in Merkez, Besni, Gölbaşı, Tut, Kahta and Samsat districts in Adıyaman province in 2021, to determine macro and micro plant nutrient data in leaves and soil and to obtain data. It is aimed to make suggestions about fertilization by considering the optimal values that should be found in a productive tree. For this purpose, 30 soil samples taken from 30 different pistachio orchards at the yielding age at a depth of 0-20 cm by drawing zigzags from different parts of the field in order to fully reflect the soil structure in the autumn month after the first rains, and the dates of 16-31 July, which is the time of mole on the fruits, for leaf analysis. It was collected from the middle of the shoot, preferably on 1-year-old branches from mature shoots. In order to determine the macro and micro nutrient contents of these samples, analysis was made in Adıyaman University Faculty of Agriculture Research and Application Laboratory. The comparison of the analysis results was carried out over the reference range values given by Adıyaman University Faculty of Agriculture Application Laboratory. According to the evaluation, when the soils were examined in terms of pH content, it was determined that they were alkaline, unsalted and partially calcareous. When examined in terms of organic matter content, it is seen that 60% of pistachio orchards have insufficient organic matter content. When soil samples are evaluated in terms of macro and micro elements; Nitrogen (N), Calcium (Ca), Magnesium (Mg) and Copper (Cu) elements are sufficient in the soil, Phosphorus (P), Potassium (K), Iron (Fe), Zinc (Zn) and Manganese (Mn) element was found to be insufficient. As a result, as a result of the evaluations made in 30 different pistachio orchards at the yield age in Merkez, Besni, Gölbaşı, Tut, Kahta and Samsat districts of Adıyaman province, it was concluded that there were nutritional problems, conscious fertilization programs based on soil and leaf analyzes should be made and producers should give due importance to soil and leaf analysis. and they need to be made aware of this issue.
