Fındıkta (Corylus avellana L.) Besin Yönetimi: Biyokömür ve Solucan Gübresi Uygulamalarının Rolü

Abstract

Bu araştırma, 2022 üretim sezonunda Düzce ili Kaynaşlı ilçesi Darıyerihasanbey köyünde, biyokömür ve solucan gübresi uygulamalarının fındığın (Corylus avellana L.) besin elementleri üzerine etkilerini belirlemek amacıyla yürütülmüştür. Tesadüf blokları deneme desenine göre üç tekrarlı olarak yürütülen çalışmada, uygulamaların toprak pH’sı ve elektriksel iletkenlik üzerinde istatistiksel olarak anlamlı bir etkisi olmadığı belirlenmiştir. Biyokömür uygulamaları fındık yapraklarındaki K, Mg, Ca, Fe, Mn, Cu, Pb ve Cd; solucan gübresi uygulamaları ise Mg, Ca, Fe, Mn, Cu, Pb, Ni ve Cd konsantrasyonlarını anlamlı düzeyde (p<0.05) etkilemiştir. Solucan gübresi × biyokömür interaksiyonu Ca, Fe, Mn, Cu, Pb, Ni ve Cd içerikleri üzerinde sinerjik etki göstermiştir. Biyokömür uygulamaları kontrole kıyasla K (%12,3), Ca (%8,7), Mg (%6,5), Fe (%15,2), Mn (%9,8), Cu (%11,4), Cd (%18,6), Ni (%7,2) ve Pb (%14,5) konsantrasyonlarını artırmıştır. Solucan gübresi uygulamaları ise K (%9,8), Ca (%7,3), Mg (%5,6) ve Cu (%8,9) içeriklerini artırırken, Fe (%6,7) ve Mn (%5,2) konsantrasyonlarını azaltmıştır. Sonuçlar, biyokömür ve solucan gübresinin fındıkta besin alımını düzenlediğini ve tek başına veya birlikte kullanımının besin yönetimi açısından önemli bir potansiyel sunduğunu göstermiştir.

Nutrient Management in Hazelnut (Corylus avellana L.): Role of Biochar and Vermicompost Applications

Abstract

This study was conducted during the 2022 growing season in Darıyerihasanbey village, Kaynaşlı district of Düzce province, to determine the effects of biochar and vermicompost applications on nutrient elements in hazelnut (Corylus avellana L.). The experiment was conducted using a randomized complete block design with three replications. The applications had no statistically significant effect on soil pH or electrical conductivity. Biochar applications significantly affected the concentrations of K, Mg, Ca, Fe, Mn, Cu, Pb, and Cd in hazelnut leaves, while vermicompost applications significantly affected Mg, Ca, Fe, Mn, Cu, Pb, Ni, and Cd concentrations (p<0.05). The vermicompost × biochar interaction had a synergistic effect on Ca, Fe, Mn, Cu, Pb, Ni, and Cd contents. Compared with the control, biochar applications increased K (12.3%), Ca (8.7%), Mg (6.5%), Fe (15.2%), Mn (9.8%), Cu (11.4%), Cd (18.6%), Ni (7.2%), and Pb (14.5%) concentrations. Vermicompost applications increased K (9.8%), Ca (7.3%), Mg (5.6%), and Cu (8.9%) contents, while decreasing Fe (6.7%) and Mn (5.2%) concentrations. The results indicate that biochar and vermicompost regulate nutrient uptake in hazelnut and that their individual or combined use has considerable potential for nutrient management in hazelnut cultivation.
