Yerfıstığında Çinko Yaprak Gübresi Uygulamasının Verim Üzerine Etkilerinin Belirlenmesi

Bu çalışmada 2000-2001 yıllarında Doğu Akdeniz Tarımsal Araştırma Enstitüsü Müdürlüğü araştırma arazisinde yerfıstığında çiçeklenme öncesi, çiçeklenme sonrası olmak üzere dört farklı dönemde uygulanan Zn yaprak gübresinin 100 tohum ağırlığı, iç oranı ve meyve verimine olan etkileri belirlenmiştir. Deneme tesadüf blokları deneme desenine göre 3 tekrarlamalı olarak yürütülmüştür. Denemede 100 tohum ağırlığı, 72.79-106 g, iç oranı % 60.03-69,60 ve meyve verimi 258-557 kg/da arasında değiştiği kaydedilmiştir. Doğu Akdeniz Bölgesi Zn sorunu olmayan alanlarda yerfıstığında çiçeklenme öncesi ve sonrası Zn yaprak gübresi uygulamasının meyve verimi ve ürün kalitesini önemli ölçüde artırmadığı tespit edilmiştir. Yerfıstığında Zn yaprak gübresi uygulaması önemli verim ve kalite artışı sağlamasa da tohumda Zn oranını artıracağı için insan beslenmesi açısından önemi göz önüne alındığında önerilebilir.

Çinkolu Yaprak Gübresi Uygulamasının Yerfıstığında Verim Üzerine Etkisi

Abstract In this study, the effects of Zn leaf fertilizer application at four different growth stages of peanut on 100 seed weight, shelling percentage and fruit yield were determined in the field of Eastern Mediterranean Agricultural Research Institute in 2000 and 2001. The experimental design was a Randomized Completely Block Design (RCBD) with 3 replications. In the experiment, it was recorded that 100 seed weight varied between 72.79 and 106 g, internal rate was between 60.03 and 69.60% and fruit yield varied between 2580 and 5570 kg/ha. It has been determined that the application of Zn leaf fertilizer before and after flowering in peanuts in the areas that do not have Zn problems in the Eastern Mediterranean region does not significantly increase fruit yield and product quality. Although the application of Zn leaf fertilizers in peanuts do not provide significant yield and quality increase, it can be recommended considering the importance of human nutrition as it will increase the Zn ratio in the seed.
