Abstract
Bu araştırma, toprağa uygulanan demir sülfat ve Fe- EDDHA' nm, demir klorozundan etkilenen şeftali ağaçlarının makro element ( N, P, K, Ca ve Mg ) kapsamları üzerine etkilerini araştırmak amacıyla yürütülmüştür. Bu amaçla Bursa yöresinde 3 şeftali bahçesi seçilmiş ve 1990 yılında topraklara demir sülfat 500 g ve 1000 g FeS04.7H20 / ağaç. , Fe-EDDHA ( Sequestrene 138 Fe ) ise 100 , 200 ve 300 g / ağaç düzeylerinde uygulanmıştır. Demir sülfat toprağa 10 kg ahır gübresi ile birlikte uygulanmıştır. Demir bileşiklerini uygulamadan önce şeftali bahçelerinden toprak örnekleri alınarak bazı fiziksel ve kimyasal özellikleri belirlenmiştir. 1990 ve 1991 yıllarının iki ayrı döneminde yaprak örnekleri alınarak toplam N, P, K, Ca ve Mg analizleri yapılmıştır. Analiz sonuçları, yaprakların makro element kapsamlarının yeterli düzeyde olduğunu göstermiştir. Topraklara farklı düzeylerde uygulanan FeSO4.7H2O ve Fe-EDDHA şeftali yapraklarının N, P, K, Ca ve Mg kapsamlarını azaltmıştır. Bu yönden Fe-EDDHA'nın daha etkili olduğu belirlenmiş olmakla birlikte, bu iki bileşiğin şeftali yapraklarının makro element kapsamlarını azaltıcı etkisi düzenli olmamıştır.
This research was implemented to determine the effects of soll applied ferro sulphate and Fe-EDDHA on macro elements ( N, P. K, Ca and Mg ) contents of peach trees affected by iron chlorosis. For this purpose, three peach orchard was selected in Bursa Region. Ferro sulphate was applied to the soils at the rates of 500 g and 1000 g FeSOzt.VHaO per tree and Fe-EDDHA ( Sequestrene 138 Fe ) was applied at the rates of 100, 200 and 300 g per tree. in the year of 1990. Ferro sulphate was incorporated into the soils together with 10 kg FYM. Before the application of iron compounds, soil samples were collected and tested-for some Chemical and physical properties. The leaf samples were taken at two stages in the years of 1990 and 1991, and analysed for total N, P, K, Ca and Mg. According to the results, macro elements contents of peach leaves were found to be adequate as compared to the critical values of these elements. The applications of FeSOA.THaO and Fe-EDDHA to the soils in different rates decreased the N, P, K, Ca and Mg contents of the leaves of peach trees. Although Fe- EDDHA was found to be more effective than FeSO4.7H2O, the ettects oi tnese two compounds in decreasing macro elements contents of the leaves were not harmonious.
