    Bazı Uygulamaların Mantar Muhafazasında Kullanımı
    (Selçuk Üniversitesi, 2019) Ekinci, Melek; Yıldırım, Ertan; Dursun, Atilla
    Mantar insan sağlığı açısından önemli besinlerden biri olup, protein, mineral, vitamin vb. içerikleri bakımından tercih edilmektedir. Ayrıca çoğu mantar türleri metabolik özelliklerinden dolayı sağlık açısından değerlendirilmektedir. Mantarlar farklı değerlendirme şekilleri ile sofralarda yer almaktadır. Üretim açısından diğer tarımsal ürünlerden daha az üretilmesine rağmen tüketici talebi fazladır. Mantarların genel itibariyle hasattan sonra kısa sürede kalitesini kaybetmesi tüketiminin de kısa sürede yapılmasını zorunlu kılmaktadır. Bununla birlikte, gerek üretim sırasında gerekse hasattan sonra yapılan bazı uygulamalar ile mantarların uzun sürede muhafazası mümkün olabilmektedir. Bunlar dışarıdan yapılan kimyasal uygulamalar olduğu gibi, ışınlama ve ambalajlama teknikleri, depolama koşulları vb. uygulamalardır. Bu derleme makalesinde mantar muhafazasında kullanılabilen bazı uygulamalar çeşitli araştırmacıların yaptıkları çalışmalar doğrultusunda verilmiştir.

    Effects of Potassium and Humic Acid on Emergence, Growth and Nutrient Contents of Okra (Abelmoschus Esculentus L.) Seedling Under Saline Soil Conditions
    (Academic Journals, 2010) Paksoy, Mustafa; Türkmen, Önder; Dursun, Atilla
    The effects of potassium and humic acid (HA) on emergence, growth and nutrient contents of okra (Abelmoschus esculentus L cv. Sultani) seedlings in saline soil conditions were evaluated. Different levels of humic acid (0, 500, 1000 and 1500 mg kg(-1)) and potassium (0, 75, 150 and 300 mg kg(-1)) were applied on growing media treated with 50 mg NaCl kg(-1) before seed sowing. The experiment was designed as randomized completely factorial block and each parcel had ten pots without drainage. Two okra seeds were sown in each pot having 300 cc volumes of growth media. The seedlings were thinned to one after emergence. The seedlings were irrigated with distilled water. Seed emergence, root and shoot size, leaf number, shoot and root dry weights of the plant seedlings were determined. Macro and micro nutrient (N, P, K, Ca, Mg, S, Cu, Fe, Mn and Zn) contents of seedlings were also determined. All data were subjected to a one-way analysis of variance and separated by Duncan's multiple range test which was performed using the Costat statistical software. There were statistical differences in terms of effects of potassium and HA on the okra seedling performances. The effects of K, Ca, Na, Cu, Fe, Mn, Zn and HA applications on plant mineral (N, P, K, Ca, Cu, Fe, and Mn) contents were significant at p < 0.005.

    Sewage sludge and farmyard manure ratios in growing media affect nutrient and heavy metal contents in cucumber
    (PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2006) Sensoy, Suat; Turkmen, Onder; Cirka, Mustafa; Dursun, Atilla; Tufenkci, Serik
    This study aimed to determine the effects of substituting sewage sludge for farmyard manure in seedling growing, media on the total dry weight, as well as nutrient and heavy metal contents of cucumber plants. Seedling growing, media consisted of 2:1:2 soil (S), pumice (P) and an organic fertilizer mixture [farmyard manure (FM) + sewage sludge (SS)]. Then, SS was progressively substituted for FM, at rates of 0%, 25 %, 50%, 75 %, and 100%. Treatments were placed in a growth chamber. No additional nutrients were applied. Dry weight, and Fe, Mn, B, Zn, Cu, Mo and Cd contents were found to increase with increases in SS ratios. Conversely, N, P, K, Ca, Mg and S contents increased with increases in FM ratios. Applications of 0:1 and 1:3 FM:SS ratios provided the best results based on dry weight of seedlings; however, when plant nutrient an heavy metal contents were taken into consideration, 1:1 and 3:1 FM:SS ratios were found to be preferable.
