Özet:

The aim of this study is to determine the effects of the application of potassium in different amounts on the development of pepper beans. The work was carried out in the greenhouse of the Eskişehir Forest Fidanlık Directorate, in the 1+0 old fidanes grown from Afyonkarahisar-Ahırdağı-original grape seeds that are planted in the perlite environment in polyethylene bags. The study has determined the nutrient content of potassium in different amounts (0, 23, 35, 47, 100 and 150 ppm) and the diameter of the root throat, the length of the root, the length of the root, the number of side roots and the weight of the root. The data obtained was evaluated by the ANOVA and Kruskal-Wallis tests. Depending on the amount of potassium applied, it has been determined that the size, the diameter of the root throat and the number of side roots in the beans have changed statistically significantly. The best size and diameter development is achieved in 23 ppm process, the maximum side root formation is achieved in 100 ppm process. As a result, with the application of potassium in the grapes, the diameter and size development can be better, the number of side roots is greater, and the success in dry and semi-dry areas treating can be increased.

The aim of the study was to examine the effects of potassium at different concentrations on the growth of black pine seedlings. The study was carried out with 1+0 black pine seedlings of Afyonkarahisar-Ahırdağı origin grown in polyethene container filled with perlite in Eskişehir Forest Nursery. The seedlings were grown using different nutrient solutions with potassium concentrations of 0-23-35-47-100 and 150 ppm. Nutrient concentrations, root-collar diameter, height, root length, number of lateral roots, and dry weight of the seedlings were determined. Data were evaluated by ANOVA and Kruskal-Wallis test. According to results of the statistical analyses, potassium doses impacted on seedling height, root-collar diameter and number of lateral root. The tallest and the thickest seedlings were produced with 23 ppm potassium nutrition while the highest lateral roots with 100 ppm. As a result, it is possible to raise the afforestation success in arid and semi-arid regions by producing potassium-fed black pine seedlings with higher, thicker root-collar diameter and a higher number of lateral roots.
