Kahramanmaraş Türkoğlu Topraklarında Stevia Rebaudiana Bertoni (Şeker Bitkisi)’nin Yetiştirilmesi ve Azot İhtiyacının Belirlenmesi

Bu çalışmada, Stevia bitkisinin (Stevia Rebaudiana Bertoni) gelişimi açısından artan azot dozlarının bitki ağırlıkları üzerine önemli etkilerinin olduğu, artan azot dozları ile birlikte bitkide yaprak, gövde ve toplam kuru madde miktarlarının istatistiki olarak arttığı gözlemlenmiştir. Yaprak verim parametreleri açısından kuru madde bazında en yüksek verime 16 kg∙da-1 azot dozu ile ulaşılmıştır. Araştırma sonucunda, şeker otu bitkisinin Kahramanmaraş koşullarına adaptasyonunun iyi olduğu, farklı azot uygulamalarının verim ve bitki besin elementi konsantrasyonları üzerine önemli etkilerinin olduğu, 16 kg∙da-1 azot dozunun Stevia yetiştiriciliği açısından uygun olduğu sonucuna varılmıştır.

Growing and Determining the Nitrogen Requirement of the Stevia Rebaudiana Bertoni (Sugar Plant) in Soils of Türkoğlu in Kahramanmaraş

In this study, it was observed that increasing doses of nitrogen have significant effects on plant weights, and leaf, stem and total dry matter amounts were statistically increased with the increasing doses of nitrogen in terms of stevia plant (Stevia Rebaudiana Bertoni) growth. In respect to leaf fertility parameters, it was reached to highest yield at the dry matter basis with the 16 kg∙da-1 doses of nitrogen. As a result of the study, it was decided that the adaption of Stevia is fine for K.Maraş conditions, different nitrogen applications are significant effects on yield and plant nutrition concentrations and 16 kg∙da-1 doses of nitrogen is the optimum dose for the growth of Stevia plant.
