Abstract
In this study, different iron (Fe) sources (Fe-DTPA, Fe-EDTA, Fe-EDDHA, Fe-HBED, Fe-HUMATE, Fe-NANO, Fe-SULFATE and Fe-CITRATE) were applied to broad bean from soil and their effects on active and total Fe concentrations and some nutrient concentrations of the plant were investigated. The experiment was conducted with 4 replicates according to the completely randomized design and, 10 mg kg-1 Fe was applied to the soil. The highest dry weight of broad bean were obtained from Fe-EDDHA application in alkaline and calcareous soils, and Fe-DTPA application in acid soil. The highest total and active Fe concentration in the plant leaves was determined in Fe-EDDHA and Fe-EDTA treatments in acid and alkaline soils and and Fe-EDDHA and Fe-DTPA treatments in calcareous soil. The phosphorus (P) and potassium (K) concentrations of the plants were lower than the control with Fe treatments and the plants were found to be unsufficient in terms of P. It was determined that manganase (Mn) concentration of plants grown in acid soil was about 5-8 times higher; and Mn, zinc (Zn) and copper (Cu) concentrations of the plant were generally the highest in Fe-EDTA and Fe-EDDHA treatments. According to the results, Fe-EDDHA and Fe-EDTA in alkaline soil, Fe-EDTA and Fe-DTPA in acid soil, Fe-EDDHA and Fe-HBED applications in calcareous soil can be recommended.
Özet
Bu çalışmada, bakla bitkisine topraktan farklı demir (Fe) kaynakları (Fe-DTPA, Fe-EDTA, Fe-EDDHA, Fe-HBED, Fe-HUMAT, Fe-NANO Fe-SÜLFAT ve Fe-SİTRAT) uygulanmış, bitkinin aktif ve toplam Fe içerikleri ile bazı besin element içerikleri üzerine etkisi araştırılmıştır. Deneme tesadüf parselleri deneme deseninde dört paralelli olarak yürütülmüş, denemede toprağa 10 mg kg-1 düzeyinde Fe uygulanmıştır. Bakla bitkisinde en yüksek kuru ağırlık alkalin reaksiyonlu ve kireçli toprakta Fe-EDDHA, asit reaksiyonlu toprakta ise Fe-DTPA uygulamalarından elde edilmiştir. Bitki yapraklarında en yüksek toplam ve aktif Fe, alkalin ve asit reaksiyonlu toprakta Fe-EDDHA ve Fe-EDTA, kireçli toprakta ise Fe-EDDHA ve Fe-DTPA uygulamalarında saptanmıştır. Demir uygulamaları ile birlikte bitkinin fosfor (P) ve potasyum (K) içeriklerinin kontrolden düşük olduğu ve bitkilerin P bakımından yetersiz beslendiği saptanmıştır. Asit toprakta yetiştirilen bitkilerin mangan (Mn) içeriğinin yaklaşık 5-8 kat daha fazla olduğu belirlenmiş olup; Fe-EDTA ve Fe-EDDHA uygulamalarında bitkinin Mn, çinko (Zn) ve bakır (Cu) içeriklerinin genellikle en yüksek olduğu saptanmıştır. Sonuçlara göre, alkalin reaksiyonlu toprakta Fe-EDDHA ve Fe-EDTA, asit reaksiyonlu toprakta Fe-EDTA ve Fe-DTPA, kireçli toprakta ise Fe-EDDHA ve Fe-HBED gübreleri önerilebilir.
