Karnabaharın (Brassica oleracea var. botrytis) verim, kalite ve mineral beslenme durumu üzerine vermikompostun etkisi

Bu çalışma ile açık tarla koşullarında karnabahar yetiştiriciliğinde vermikompostun kullanım olanakları belirlenmeye çalışılmıştır. Araştırmada gübreleme materyali olarak vermikompostun yanı sıra kimyasal gübreler de kullanılmış olup uygulama konuları şu şekildedir: K-0 (kontrol), VK-0 (0 kg da-1 vermikompost + N:P:K), VK-1 (100 kg da-1 vermikompost + N:P:K), VK-2 (200 kg da-1 vermikompost + N:P:K), VK-4 (400 kg da-1 vermikompost + N:P:K) ve VK-8 (800 kg da-1 vermikompost + N:P:K). Çalışma sonunda alınan bitki örneklerinde kalite özellikleri (bitki boyu, taç çapı, taç yüksekliği, minimum ve maksimum taç ağırlığı, ortalama taç ağırlığı, SÇKM: Suda çözünebilen kuru madde, pH ve Vitamin C), dekara verim değerleri ve bitkinin mineral beslenme durumu (N, P, K, Ca, Mg, Fe, Zn, Mn, Cu) belirlenmiştir. Elde edilen sonuçlara göre vermikompost karnabaharın kalite özelliklerini, mineral beslenme durumunu ve dekara verim değerlerini kontrole göre istatistiksel düzeyde olumlu yönde etkilemiştir. Ancak, en yüksek vermikompost dozunda (VK-8) karnabaharın veriminde azalma gözlemlenmiştir. Ayrıca, taç çapı ile karnabahar verimi arasında pozitif ilişki belirlenmiş iken taç çapı ile azot (N), potasyum (K) ve demir (Fe) değerleri arasında negatif ilişki tespit edilmiştir. Bununla birlikte, karnabahar yetiştiriciliğinde kimyasal gübrelemeye (6 kg da-1 N, 3 kg da-1 P2O5, 6 kg da-1 K2O) ek olarak vermikompostun 200 ila 400 kg da-1 dozlarında uygulanmasının uygun olabileceği düşünülmektedir.

The effect of vermicompost on yield, quality and nutritional status of cauliflower (Brassica oleracea var. botrytis)

The aim of this study was to investigate the possibility of vermicompost utilization in cauliflower cultivation. Along with vermicompost, chemical fertilizers were also used. The treatments used in the study are as follows: K-0 (control), VK-0 (0 kg da-1vermicompost + N:P:K), VK-1 (100 kg da-1vermicompost + N:P:K), VK-2 (200 kg da-1vermicompost + N:P:K), VK-4 (400 kg da-1vermicompost + N:P:K), and VK-8 (800 kg da-1vermicompost + N:P:K). At the end of the cultivation period, plant samples were analyzed for quality parameters (plant height, curd diameter, curd height, minimum and maximum curd weight, average curd weight, water soluble dry matter, pH, and vitamin C), yield, and concentration of plant mineral nutrients (N, P, K, Ca, Mg, Fe, Zn, Mn, Cu). According to the data obtained, vermicompost improved quality parameters, nutritional status and yield compared to the control treatment in statistically significant level. However, the highest vermicompost dose (VK-8) appeared to reduce the yield. While a positive correlation between curd diameter and yield of cauliflower is determined, a negative correlation between curd diameter and nitrogen (N), potassium (K), iron (Fe) values is found. Based on these findings, it is thought that, in addition to chemical fertilizers (6 kg da-1 N, 3 kg da-1 P2O5, 6 kg da-1 K2O), application of vermicompost in 200-400 kg da-1 doses might be adequate in cauliflower cultivation.
