Geleneksel ve Analize Dayalı Kimyevi Gübre Uygulamasının Mısır Verimi ve Yaprakta Bitki Besin Elementleri İçeriğine Etkisi Nureddin Öner; Öner, Filiz This study is conducted in Muğla Dalaman Agricultural Management Directorate (TİGEM) in 72MAY80 grain and silage maize in the trial area according to purely random trial the randomized complete block design in 3 replications in 2016. The amount of fertilizer is obtained by substracting elements determined by soil analysis from the amount of plant nutrients required for corn yield in -1 in 950 kg. (-1 in 41.5 kg urea). The aim of this research is to determine whether fertilizer application at 4 different rates including the reduction of fertilizer application required for corn yield -1 in 950 kg. by 40% (-1 in 24.95 kg urea) and increasing it by 40% (-1 in 58.1 kg urea) and manufacturer application (-1 in 60 kg urea, -1 in 32,3 kg, 15-15-15 and -1 in 14 kg. KNO3) has an effect on the yield of corn plant and the element content of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), iron (Fe), copper (Cu), zinc (Zn), manganese (Mn), boron (B) and molybdenum (Mo) in the leaf. The urea applied to the soil from the base, 15-15-15, fertilizers are given to the band with the sowing seeder. The urea fertilizer used as a top fertilizer in trial plots and KNO3 fertilizer has been applied with drip irrigation system at 3 different times. According to the research results, the effect of applying fertilizer to the soil according to -1 in 950 kg. corn yield, 40% reductions and 40% increases in fertilizer application, and manufacturer application on the yield of corn and the concentration rate of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), iron (Fe), copper (Cu), zinc (Zn), manganese (Mn), boron (B) and molybdenum (Mo) elements in the leaf is found to be statistically significant (p<0.01). The highest yield in corn plant is achieved in the application of manufacturer (-1 in 1.367,0 kg) and the application of increasing the amount of fertilizer by 40% (-1 in 1357.0 kg), fertilizer application according to -1 in 950 kg corn yield (-1 in 1225.3 kg), respectively, whereas, the lowest yield is achieved in the application of reducing the amount of fertilizer by 40% (-1 in 991.0 kg). Moreover, the total amount of fertilizer used in trial plots is calculated according to the fertilizer costs in 2016 and the price spent on fertilizer is determined in Turkish Liras (TL) and this price is divided by the 2016 corn kg price and subtracting the amount of corn obtained from the yield, and net yield is obtained excluding the fertilizer cost.

Bitki patojenlerinin kontrolünde kullanılan biyokontrol ürünler ve özellikleri Yiğit, Fahri Son günlerde sağlık ve çevre güvenliğine artan ilgiden dolayı toksik, kanserojen ve çevresel açıdan zararlı kimyasalla¬rın kullanım isteği kırılmaktadır. Bu bakımdan, gelişmiş ülkelerde güvenilir, biyolojik kaynaklı ürünlere karşı artan bir talep vardır. Ülkemizde konvensiyonal ve organik tarım yapan yetiştiricilerimiz ile ilgili son gelişmeler biyokontrol ürünlerindeki kullanıma olan ilginin arttığını işaret etmekte olup, bu da önümüzdeki yıllarda biyokontrol ürünlerinin pazar potansiyelinin artacağını göstermektedir. Bu derlemenin amacı bu ürünler hakkında hem bilgi vermek ve hem de özelliklerini sunmaktır.; Because of growing concerns about health and environmental safety, the use of toxic, carcinogenic, and environmentally damaging chemicals is recently being discouraged. In this respect, there is a growing demand for sound, biologically-based biocontrol products in developed countries. Recent advances of both conventional and organic growers indicate an interest in using biocontrol products in our country, suggesting that the market potential of biocontrol products will increase in coming years. Aim of this review is to both give knowledge about these products and to present their features.

Pentachloronitrobenzen (PCNB) uygulanmış seralardaki domateslerde kök çürüklüğü etmenlerinin tespiti ve hastalığının yaygınlığı

Pentachloronitrobenzen (PCNB) uygulanmış seralardaki domateslerde kök çürüklüğü etmenlerinin tespiti ve hastalığının yaygınlığı Yiğit, Fahri Pentachloronitrobenzen'in (PCNB) domates seralarında kok çürüklüğü etmenlerinin niceliği, niteliği ve hastalığın yaygınlığı üzerine etkisini saptamak amacıyla yapılan bu çalışmada, PCNB uygulanmış ve kontrol amaçlı 10'ar adet sera seçilerek hastalıklı bitkiler sayılmış ve her bir seradan tesadüfen seçilen 6 'şar adet hastalıklı bitkiden izolasyon yapılmıştır. Araştırma sonucunda Fusarium türleri kontrol seralara göre %20.9 daha fazla tespit edilmiştir. Toplam funguslar içindeki Fusarium oranları PCNB'li serada %85.05, kontrolde ise %75.67 oranında kaydedilmiştir. Ayrıca PCNB ile ilaçlanmış seralardaki hastalıklı bitkilerin %85.60'sında, kontrol seralardaki bitkilerin %66.4'ünden Fusarium türleri izole edilmiştir. Rhizoctonia solani ve Colletotrichum coccodes kontrole göre sırasıyla %71.43 ve %60 oranında daha az tespit edilmiştir. Kontrol ve PCNB uygulanan seralardaki hastalık oranları ara-sında önemli ilişki (P:0.05) tespit edilmemiştir.; In this study, ten greenhouses for each of two groups as pentachloronitrobenzene (PCNB) treated and nontreated were chosen for sampling and observations to determine the quantative and qualitative effects of PCNB on the root rot pathogens of tomato and the prevalence of the disease under greenhouse conditions. Six diseased plants were randomly collected from the each of greenhouse after determination of the disease incidence rates, and the isolation studies were carried out with the diseased plant samples. According to the results the average amount of Fusarium spp. were 20.9 % more than those which were in the controls. The ratio of Fusarium spp. among the total fungal isolates were found 85.05% for PCNB and 75.67% for control. In addition, Fusarium spp. from diseased plants were 85.6% and 66.4% in PCNB treated and nontreated greenhouse respectively. Rhizoctonia solani and Colletotrichum coccodes were found in less amounts 71.43% and 60% respectively in comparison with control. There no statistical significant difference (p:0.05 level) betwee'n the control and PCNB applied greenhouses.

Effects of Zinc Applications on Nutrient Contents of Up Ground Parts in Lentil (Lens Culinarismedic.) Varieties

Effects of Zinc Applications on Nutrient Contents of Up Ground Parts in Lentil (Lens Culinarismedic.) Varieties Toğay, Yeşim; Toğay, Necat; Gülser, Füsun Legumes are an important source of protein, vitamins, minerals and complex carbohydrates in diets of a large number of people, especially in developing countries. Among legumes lentil is the second leading grain legume crop after chickpea in Turkey. The lentil, a legume crop, fixes atmospheric nitrogen in the root-nodules in a symbiotic relationship with Rhizobium bacteria. It is an important crop because of its high protein content of seed and straw for human and animal nutrition. The current productivity trends of lentil are decreased on decades. Poor fertilization area is considered as an important factor effecting this decreasing. The plant needs some macroand micronutrients for its normal growth. Lentil seeds have a quite high protein content (18-30 %) varied according to environmental conditions, varieties and agronomic process. Zn is an essential nutrient in plants, animal and humans. In human’s Zn deficiency causes severe health complications, including impairments of physical growth, immune system and learning capacity, DNA damage and cancer development (Levenson and Morris, 2011). It was reported that more than 30% of the world’s populations is Zn deficient, with Zn deficiency being the 11th most important factor causing disease or death in the world (WHO Micronutrient Deficiencies, 2011). Zinc contents of plants plays an important role in plant reproduction. Its deficiency inhibits floral development, male and female gametogenesis, fertilization and seed development. Pandey et al. (2006) reported that zinc deficiency reduces plant growth, pollen viability, flowering and grain production in plants. Studies show that 30% of the arable areas in the world and 50% of the agricultural soils in Turkey suffer from zinc deficiency (Kenbeay and Sade, 1987). The Van region is among the areas most severely affected by zinc deficiency (Eyüboğlu et.al. 1998, Çamaş et al. 1998). This study was carried out to investigate the effects of zinc applications on nutrient contents of up ground parts of lentil varieties in the Van region in eastern Turkey.
