Öğe Artan vermikompost ve azot-Fosfor (NP) uygulamalarının sümbülün (hyacinthus orientalis L. “purple star”) Co, Ni, Cd ve Mo içeriklerine etkisi(Uluslararası Tarım ve Yaban Hayatı Bilimleri Dergisi, 2019) Sönmez, Ferit; Çığ, ArzuBu çalışma son yıllarda kullanımı oldukça yaygınlaşan vermikompostun sümbülün Co, Ni, Mo ve Cd içeriklerine etkisini araştırmak için arazi çalışması olarak yürütülmüştür. Deneme Siirt Üniversitesi Kezer Yerleşkesi içinde yer alan Bahçe Bitkileri Bölümüne ait deneme alanında 3 tekerrürlü olarak tesadüf blokları deneme desenine göre kurulmuştur. Denemede vermikompostun 4 dozu (0, 25, 50 ve 100 g/soğan) ve azot-fosfor (NP) olarak 20-20-0 (N-P-K) gübresinden 4 doz (0, 2, 4, 8 kg da-1) uygulanmıştır. Deneme sonunda hasat edile sümbülün yaprak ve soğanında elementel analizler yapılmıştır. İstatistiksel analiz sonucunda vermikompost ve NP uygulamalarının sümbülün nikel, molibden ve kadmiyum içerikleri üzerine P<0.01 düzeyinde önemli etki yaptığı, kobalt içeriği üzerine etkisinin olmadığı belirlenmiştir. Soğan ve yaprağın element içeriklerinin birbirlerine göre önemli düzeyde farklılık gösterdiği (p<0.01) belirlenmiştir. Vermikompost uygulamaları ile kontrole göre sümbülün yaprak nikel ve kadmiyum içerikleri artarken, kobalt ve molibden içerikleri önce artmış sonra azalmıştır. Artan NP uygulamaları ile kontrole göre yaprak kobalt ve nikel içerikleri artmış, molibden ve kadmiyum içerikleri azalmıştır. Vermikompost ve NP uygulamaları ile sümbül soğanının nikel, molibden, kobalt ve kadmiyum içeriklerinde kontrole kıyasla değişimler belirlenmiş, en belirgin değişimler kobalt, kadmiyum ve molibden içeriklerinde ortaya çıkmıştır.Öğe Bazı Sümbül Çeşitlerinin Besin Elementlerinden Faydalanma Farklılıklarının Ortaya Konulması(Iğdır Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2011) Çığ, Arzu; Sönmez, Ferit; Türkoğlu, Nalan…Öğe Comparing heavy metal contents of roadside soils with coastal area soils(Journal of International Environmental Application & Science, 2013) Gülser, Füsun; Sönmez, Ferit; Çığ, ArzuIn this study, accumulation of heavy metals in roadside soils was investigated. Soil samples were taken from the refuges of main road (polluted positions) and from the coastal areas (unpolluted positions) far away from the intensive traffic. Iron, zinc, copper and nickel contents of soil samples changed with the sampling positions. There were significant differences (P<0.01) among the locations for lead contents of soils. The mean lead contents in unpolluted positions and polluted positions were determined as 0.581 ppm and 0.887 ppm, respectively. The percentage increases in heavy metal concentrations in polluted positions according to unpolluted positions were obtained for zinc (374.16 %), copper (291.40 %), lead (236.41 %) and nickel (736.87 %).Öğe The Determination of Phytoremediation Levels of Ornamental Plants Used in Landscape(Journal of International Environmental Application & Science, 2011) Gülser, Füsun; Çığ, Arzu; Sönmez, FeritNowadays, environmental pollution related in industrial development is one of the most important problems. The researches in this field are generally conducted using hyper accumulator plants. The phytoremediation properties of some ornamental plants used in landscape have been also investigated. The objective of this study was to determine accumulation of heavy metals in leaves of some ornamental plants used in the landscape of Yüzüncü Yıl University campus area near Lake Van. Leaf samples of the plant species belong to leafy, coniferous and shrub were taken from the refuge of main road in the campus area affected heavy metal pollution due to intensive motorized traffic, and from the coastal areas far away from the intensive traffic. Nickel, lead, cadmium, iron, zinc and copper concentrations were determined in leaf samples. There were significant differences among the plant species (P<0.01) according to Fe, Zn, Cu, Ni, Pb and Cd contents of leaves. There were also significant differences among the locations (P<0.01) for Fe, Zn, and Cd contents of leaves. Interactions between locations and plant species were significant (P<0.01) for the heavy metals, except Pb. The highest Fe, Zn, Cu, and Cd concentrations were obtained in species of Cedrus libani A.Rich (618 ppm), Betula alba Linn. (106.30 ppm), Salix alba L. (24.54 ppm) and Eleagnus angustifolia L. (0.28 ppm), respectively. The highest Ni (6.36 ppm) and Pb (3.76 ppm) contents were determined in Pyracantha coccinea M. Roem.Öğe Effect of Phosphorus and Molybdenum Applications on Macro and Micro Nutrient Content of Bean (Phaseolus vulgaris) Straw and Grain(2024) Erman, Murat; Çığ, Fatih; Sönmez, Ferit; Cerıtoglu, MustafaThe aim of this research is to investigate the effect of phosphorus and molybdenum treatment on macro and micronutrient biofortification in bean. The study sheds light on the individual and interactive effects of phosphorus and molybdenum on macro and micronutrient uptake and biofortification in Phaseolus vulgaris. Three levels of phosphorus and molybdenum were used in the experiment laid out in a randomized block design with four replications. Phosphorus and molybdenum treatment promoted nitrogen accumulation in both straw and seed. Nitrogen content increased with rising phosphorus doses in straw and seed over control by 42.3% and 7.4%, respectively. Moreover, phosphorus addition increased straw manganese content while molybdenum enhanced straw manganese. In addition, 4 g Mo kg-1/seed treatment boosted seed magnesium concentration over control by 28.2%, however, no phosphorus, potassium, copper, iron, and zinc in the plant materials, likely due to the sufficient levels of these nutrients in the soil composition of the experimental area. According to results, nitrogen, phosphorus, potassium, calcium, magnesium, manganese, copper, iron, zinc varied in straw and seed between 3.15-7.05% and 17.5-19.2%, 586-990 ppm and 1049-1355 ppm, 695-2690 ppm and 1021-1727 ppm, 5839-11162 ppm and 559-1303 ppm, 690-1474 ppm and 348-1036 ppm, 25.3-38.3 ppm and 8.29-9.29 ppm, 8.6-16.9 ppm and 11.3-19.9 ppm, 469-927 ppm and 70.2-80.3 ppm, 6.5-10.8 ppm and 17.9-23.3 ppm, respectively. Consequently, it has been determined that molybdenum supplementation is necessary along with phosphorus fertilization in areas where beans are grown, especially in acidic soils.Öğe The effects of some organic fertilizers on nutrient contents in hybrid Gladiolus(Eurasian Journal of Soil Science, 2013) Sönmez, Ferit; Çığ, Arzu; Gülser, Füsun; Başdoğan, GülçinayThe objective of this research was to determine the effects of organic fertilizers on nutrient contents in leaves and corms of hybrid Gladiolus sp. used as a cut flower in landscape arrangement. This study was conducted in a randomized experimental design with three replications. Chicken manure, farmyard manure, peat and waste mushroom compost were used as organic fertilizers. As a result, while the highest mean contents of nitrogen (1.97%), iron (160 ppm) and manganese (128 ppm) in leaves were obtained in chicken manure application, the highest mean contents of potassium (2.01%), calcium (1.80%) and magnesium (0.25 ppm) were determined in waste mushroom compost application. The highest mean contents of phosphorus (0.30%), zinc (25.3 ppm) and copper (9.29 ppm) in leaves were found with peat, control and farmyard manure applications, respectively. The highest mean contents of phosphorus (0.83%), potassium (1.47%), calcium (0.57%), manganese (73 ppm) and zinc (67.3 ppm) in corms were obtained in farmyard manure applications. While the highest mean contents of nitrogen (4.86%) and copper (20.9 ppm) in corms were determined in chicken manure application, the highest mean contents of iron (17.6 ppm) and magnesium (0.20 %) in corms were obtained in peat and waste mushroom compost applications, respectively. Application of organic fertilizers increased macro and micro nutrient contents in leaves and corms of hybrid Gladiolus sp.
