  • Determination of Weeds and Their Control Methods in Daffodils and Hyacinth

    • Authors: Koray Kaçan; Çetin Özkul, Yıldız Sokat
      Abstract: This study was carried out fordetermine the problem weeds on daffodils and hyacinth in İzmir between 2013 and2014. O. pes-caprae (94.74 %) was determined as highestfrequency of occurrence in study.  E. cicutarium (52.0 %), B. tectorum (50,0 %), H. murinum (44.74 %) and G.aparine (44.73 %) together with this weedwere listed in the survey as the first five weeds. As sour grass is the weedtype with the highest frequency of occurrence (O. pes-caprae)and as it is an invasive weed, it is estimated that it will spread more in thefollowing years. O. pes-caprae (115.42 Weeds/m2) hasbeen identified as the densest weed in terms of the weed density. H. murinum (34.38 Weeds/m2), A. sterilis(26.29 Weeds/m2), T. repens (14.29 Weeds/m2), B. tectorum (11.42 Weeds/m2), E. cicutarium(8.47 Weeds/m2) followed it respectively. Herbicides with 4different active substances were taken under evaluation in 3 replicationsaccording to a randomized complete block experiment design. When the effects ofherbicides on weed dry weights, the greatest effect was obtained fromOxyfluorfen herbicide (43.20 %). This effect was closely followed by Picloram +2,4 D (43,18 %). Other effective applications were Aclonifen effect (38.10 %)and Phendimethalin (36.00 %) and Solarization (5.60%).

  • Count of main pest of Oil-Bearing (Rosa damascena Miller)’s Rose Soft
           Scale (Rhodococcus perornatus Cockerell & Parrott) by using image
           processing methods

    • Authors: Ayşenur Yılmaz; Abdülkadir Çakır, Ozan Demirözer
      Abstract: Harmful counting of oil roses iscarried out by agricultural experts using direct counting method (understereomicroscope, generally 40X Zoom). But frequent influences from humansituations such as fatigue, boredom and carelessness cause counting errors. Themethod of outputting the project differs because it is a method which has notbeen applied in this field before and because error rate is not reduced tozero. Dish samples taken from the oil roses grown in Isparta central regionwere separated into 1.5 cm pieces and prepared for measurement. 13 samplebranch images were taken by Leica brand Z16 APO model macroscope (1XMagnification); (0.57 Zoom factor); (16: 1 Zoom) scaled. Acquired images wereprocessed in the Leica las 4.50 microscope software platform by performing thenecessary image quality enhancement operations. Images from the macroscope areconverted into countable form by Matlab program and software language usingmorphological image processing methods. An algorithm has been created to determinationof the 2.nimf adults cochineal, 1.nimf cochineal and 2.nimf cochineal andcalculate average cochineal dimensions. Counting was done and schedules werearranged according to the written algorithm.

    • Authors: Çiğdem Sönmez; Ayşe Özge Şimşek Soysal, Amir Hasan Taghiloofar, Emine Bayram, Hakan Çoşkunol
      Abstract: Thisstudy was carried out in the field of organic production at the Menemenresearch and production farm of Ege University in 2014-2015 and 2015-2016. Inthis research that conducted for two years, were investigated of the effects offour different row spacings (30 cm, 40 cm, 50 cm and 60 cm) on some yield andquality characteristics of Borago officinalis L.. In the first andsecond years of the experiment, the plant height, 1000 seed weight, number ofbranches, number of inflorescences and seed yield were changed between 58.16-77.00 cm, 65.86- 75.93 cm; 16.3- 17.0 g, 15.0-16.4 g; 5.96- 7.46 per plant,6.55- 8.10 per plant; 27.40- 41.86 per plant, 31.50- 33.85 per plant; 44.38-76.39 kg/da, 41.67- 79.72 kg/da respectively. In both experiment years, in investigatedparameters were observed increase except 1000 seeds yields in these values withthe increases of the distance between rows. Further oil ratio was determined inthe range of % 29.96- 34.04 and % 30.13- 33.67 at the first and second years ofexperiment respectively.  The result ofthe experiment indicated that there was a decrease in oil ratio as increases ofthe distance between rows. Analysis of fatty acids oil of Borago officinalisL. indicated that the ratio of palmitic acid, stearic acid, oleic acid,linoleic acid, ϒ-linolenic acid, eicosenoic acid and erucicacid were %13.10-13.31, %3.78-4.07, %20.26-20.74, %36.40-37.54, %18.20-18.71,%4.09-4.25 and %2.36-2.60 in averages of years respectively. Inresult,  it is possible to say that 50 cmdistance between rows must be applied in order to obtain an acceptable highlevel of oil content with seed yield in Borago officinalis L.

  • Effects of Grafting on Nutrient Element Content and Yield in Watermelon

    • Authors: Şafak Ceylan; Özlem Alan, Ömer Lütfü Elmacı
      Abstract:   This study was conducted to determine the effects of grafting and rootstock-scioncombinations on the yield and nutrient content for both the leaves and fruit ofwatermelons. Two watermelon (Citrilluslanatus (Thunb.) Matsum and Nakai) varieties Crisby and Crimstar weregrafted on to Ferro and RS 841, and the commercial hybrids of Cucurbita maxima x Cucurbita moschata.Non-grafted plants were used as controls. In the grafted plants the content of K, Mg, Ca, Fe, Cu, Zn and Mn in the leaves and N in fruitssignificantly increased when compared to the control. A significant effect wasobserved in the rootstocks for the Fe, Cu, Zn content in the leaves and the N,P, Ca, Cu and Zn content in the fruit. The K and Fe content in the leaf and theFe, Cu, Zn and dry matter content in the fruit were also found to besignificant between the varieties. Grafting and rootstock-scion combinationsaffect fruit yield. The Crimstar/Ferro combination had the highest yield. Also,in the grafted plants, the dry matter content ofthe fruits had a significant positive correlation with the Ca and Mg content ofthe leaves.

  • Effects of Liquated Humic Substances on Runoff, Soil Losses by Runoff and
           by Splash under Artificial Rainfall Conditions

    • Authors: Tognisse Herve Sinkpehoun; Gökçen Yönter
      Abstract: Soil, one of the most important natural resources, is lost by water andwind erosion. Addition of organic materials into the soils is commonly used forreducing soil and water losses. In this studyliquated humic substances were applied at different doses (0, 5, 10, 20 and 40ml l-1) to investigate its effects on runoff and soil losses causedby runoff and splash under artificial rainfall conditions on soil surface.Liquated humic substances were sprayed by a hand type pomp uniformly on thesurface of the soil samples in the erosion pans (30 x 30 x 15 cm; at a slope of9 %) and then simulated rainfall (40 mm h-1) was applied to thesepans for 1 hour. The results indicated that, increases in humic substancesdoses reduced runoff (24-45 %), soil losses by runoff (7-97 %) and by splash(3-37 %), significantly (P < 0.01).

  • Effect of Different Packages on Organic Dried Fig Fruit Quality During
           Shelf Life

    • Authors: Hasan Kuruçaylı; Fatih Şen
      Abstract: The study was conducted to determinequality changes of organic dried figs packaged in different packages throughoutshelf life. Dried figs were produced organically (cv. Sarilop) were packed asnatural with doypack, tray, quadro and polyethylene (PE) bags. Dried figs werestored at 20±1°C and 50-65% relative humidity for 6 months. It has beendetermined that different package types affect the moisture content of driedfigs and cause increase and decreases in hardness, total soluble solid contentand water activity. At the end of storage, the moisture content of dried figfruits was highest (19.84%) in the doypack package and lowest (18.26%) in thePE bag. It was determined that the hardness values of the dried figs in the PEbag were 14.8% higher than the other packages at the end of storage At the end of storage, the sugar index on the surface of the dried figsin the quadro packaging was found to be highest at 3.89. In general, theeffects of different package types on the color and other quality parameters oforganic dried figs have been limited. Results showed doypack packages may berecommended for organic dried figs but there might be problems in PE bags packagesrelated to some quality parameters.

  • Determination of Plant Species can be used in Xeriscape design under
           Mediterranean conditions : The Sample of Antalya/Konyaaltı

    • Authors: Nefise Çetin; Sibel Mansuroğlu
      Abstract:   Failurein plant selection, usingturf and annual plants over large areas in landscape designs increase thepressure on already limited water resources. Especially in mediterraneanclimate conditions, because of the incorrect plant choices in landscape designplants dry even die during the summer months. Accordingly, such as“Xeriscaping” which uses limited water, must be adopted instead of traditionallandscape designs that require a large amount of irrigation. This study isconduct on the approach that the most important subject about water saving inplanting design is correct selection of plants and, that the sustainability oflandscape can be improved by designing with plants suitable for the naturalstructural features of the area. The study aims to determine the plant speciesand the features of these plants that can be used for xeriscape design undermediterranean conditions which has long arid periods, for the benefit oflandscape applications the availability of these plants in nurseries wasinquired. Climate was analysed elaborately by studying the sample of Antalya/Konyaaltıcounty. Some suggestions have been developed to popularize the use of droughttolerant plants and on the production of drought tolerant plants not found inthe nursery.
