FARKLI ŞEKİLLERDEKİ POTASYUM SÜLFAT UYGULAMALARININ YÜKSEK SICAKLIK STRESİNDEKİ BİBERLERDE MEYVE VERİM VE KALİTESİNE ETKİLERİ

Çalışma biberde yapraktan (%1, %2, %3) ve topraktan (5-10-20 kg da-1) farklı dozlarda uygulanan potasyum sülfat (K2SO4) gübresinin yüksek sıcaklık stresi altında verim ve kaliteye etkisi incelenmiştir. Deneme tesadüf parselleri deneme desenine göre kurulmuştur, her uygulama 3 tekerrürden oluşmuştur. Deneme sonucunda potasyum uygulamalarının kontrol ve stres parsellerinde önemli etki ettiği tespit edilmiştir. Potasyum uygulamalarının stres koşulları altında meyve tane ağırlığını, meyve boyu ve çapını, meyve eti kalınlığını arttırdığı tespit edilmiştir. Özellikle yapraktan uygulanan potasyum sülfat stres koşullarında; meyve sayısının, meyve tane ağırlığının, meyve hacminin ve meyve eti kalınlığının arttığı belirlenmiştir. Potasyum uygulamalarının kontrol ve stres parsellerindeki meyvelerin N, P, K, Ca, Mg, Cu, Fe konsanstrasyonlarını olumlu yönde etkilediği sonucuna varılmıştır.

The Effects of Potassium Sulfate Applications in Different Shapes on Fruit Production and Quality in High-Temperature Stress Pepper

In this study, the effect of potassium sulfate (K2SO4) fertilizer applied at different doses from leaves (1%, 2%, 3%) and soil (5-10-20 kg/da) on yield and quality was investigated under high-temperature stress. The experiment was established according to the randomized plot design, each application consisted of 3 replications. As a result of the experiment, it was determined that potassium applications had a significant effect on the control and stress plots. It was concluded that potassium applications increased fruit berry weight, fruit size and diameter, and fruit flesh thickness under stress conditions. Especially under foliar application of potassium sulfate stress conditions; It was concluded that fruit number, fruit grain weight, fruit volume, and fruit flesh thickness increased. It was determined that potassium applications positively affected the N, P, K, Ca, Mg, Cu, and Fe concentrations of the fruits in the control and stress parcels.
