    APPLICABILITY OF CHLOROPHYLL METER READINGS AS YIELD PREDICTOR IN DURUM WHEAT
    (Taylor & Francis Inc, 2010) Yildirim, Mehmet; Kilic, Hasan; Kendal, Enver; Karahan, Turan
    Chlorophyll meter (SPAD) readings can play an important role in selecting promising lines for wheat breeding. Twenty five durum wheat (Triticum turgidum L. var. durum) genotypes were grown under irrigated and rainfed conditions at two locations in Diyarbakir, Turkey during 2005 and 2006. The aim of this study was to evaluate the genetic variation in SPAD readings, and to determine relationships among SPAD readings, grain yield, grain quality and yield parameters. SPAD readings were taken at heading and grain middle milky stages. SPAD readings exhibited greater genotypic variance compared with grain yield and protein content. Genotype by environment interaction variance did not associate with SPAD readings and, grain yield. At both measuring stages there were positive correlations between SPAD and grain yield. Correlation analysis revealed that grain yield under both rainfed and irrigated conditions was mostly determined by grain number. These results suggest that SPAD readings can be used as selection criteria to select durum wheat genotypes that are high yielding but without any decrease in grain protein content.

    (Medwell Online, 2008) Gul, Ismail; Demirel, Ramazan; Kilicalp, Numan; Sumerli, Mehdi; Kilic, Hasan
    The effect of different harvesting times on some silage quality of maize, sorghum and sorghumxsudangrass hybrids grown as in a split plot design with 3 replicates during second crop in semi and condition were evaluated. In this research, whole plant silage chemical composition and DM digestibilities on different times, measured in vivo were determined. For this purpose, 2 maize (DK 711, TTM 815), 2 sorghum (Sucro sorgo 506, FS 5) arid 2 sorghum-sudangrass hybrids (P 988, Grazer N2) cultivars were harvested at 3 different maturity stages (mid-flowering-MF, milkline-ML and hard dough-HD). The chopped materials were ensilaged in 10 L anaerobic jars, for 60 days. Silage samples were dried (CP, FP, pH, ADF, NDF contents were measured) and incubated in fistulated 3 Holstein Friesian heifers for determining dry matter digestibility. Significant differences were found between plant cultivars and harvesting Stages for all investigated parameters. The dry matter yields varied between 12654.2 and 25340.1 kg ha(-1). The highest dry matter yield was obtained from Sucro Sorgo 506 with ML and HD. Dry matter content of silages were changed from 20.63% (in silage sorghum cv. FS 5) to 27.36% (in sorghum-sudangrass hybrids cv. Grazer N2), pH (3.84 in FS 5 and 3.98 in TTM 815), Fleig point (FP) (90.87 in TTM 815 arid 104.6 in Grazer N2), Crude Protein (CP) was 3.92% in GrazerN2 and 6.64% in FS 5, ADF was 44.56% in DK 711 arid 49.33% in SS 506, NDF was 59.56% in DK 711 and 65.70% in P 988, whereas in vivo DM digestibility at 12 h was 32.82% in SS 506 arid 38.91% in TTM 815. Crop maturity increased satistically significantly, silage DM varied from 20.43-25.92% and in vivo digestibility of DM at 12 h varied from 32.56-37.66%, however significantly decreased. ADF decreased from 50.17-42.56%, NDF decreased from 64.71-59.62%), WSC (Water Soluble Carbohyrates) increased from (24.59-30.24%). CP decreased from 5.59-5.05%. pH was between 3.78-4.10 arid Fleig point was between 94.66-97.58. These Values were not changed statistically, when crop maturity increased. Incubation periods were 0, 12, 24, 48 arid 72 11 for determining dry matter digestibility by using nylon bag technique. Silage NDF values were decreased from flowering to milkline stages. It was concluded that silages in vivo DM digestibility were increased with maturity at 12 h rumen incubation.

    Effects of different previous crops and nitrogen rates on double cropping maize (Zea mays L.)
    (Asian Journal Of Chemistry, 2008) Gul, Ismail; Akinci, Cuma; Doran, Ilhan; Kilic, Hasan; Baytekin, Harun
    The effects of previous crops (wheat, barley, lentil, Hungarian vetch and fallow) and different nitrogen rate (0, 120, 160, 200 and 240 kg N ha(-1)) on grain yield and yield components of maize (Zea mays L.) were evaluated under irrigated conditions in Diyarbakir, Turkey in the 1999-2000, 2000-2001 growing seasons. Maize was grown in summers and wheat, barley, lentil and Hungarian vetch in winters. In-the study, grain yield of maize varied between 6340.3 and 11598.9 kg ha(-1). It was determined that Hungarian vetch was suitable for previous crop and 160 kg ha(-1) N rate is the best nitrogen rate in maize production. According to the interaction of previous crop-nitrogen rate, the highest yield was obtained from the subject grown after lentil and Hungarian vetch with 160 kg N ha(-1). Maize following legumes in rotation did not respond to applications over 160 kg N ha(-1), while barley-maize, wheat-maize increased at all levels of N applied. Fallow-sorghum did not respond to-application over 200 kg N ha(-1).

    Evaluation of Antibiotic Susceptibilities and VISA-VRSA Rates Among MRSA Strains Isolated from Hospitalized Patients in Intensive Care Units of Hospitals in Seven Provinces of Turkey
    (Ankara Microbiology Soc, 2012) Cesur, Salih; Irmak, Hasan; Simsek, Husniye; Coplu, Nilay; Kilic, Hasan; Arslan, Ugur; Bayramoglu, Gulcin
    The aim of this study was to determine whether vancomycin resistant Staphylococcus aureus (VRSA) and vancomycin intermediate susceptible S.aureus (VISA) strains were present among methicillin-resistant S.aureus (MRSA) strains isolated from patients hospitalised at intensive care units (ICU) of hospitals located at different regions of Turkey and to determine the minimum inhibitory concentration (MIC) values of teicoplanin, linezolid, tigecycline, quinupristin-dalfopristin and daptomycin, which are alternative drugs for the treatment of MRSA infections. A total of 260 MRSA clinical strains (isolated from 113 lower respiratory tract, 90 blood, 24 wound, 17 catheter, 13 nasal swabs, two urine and one CSF sample) were collected from nine health-care centers in eight provinces [Ankara (n=52), Konya (n=49), Antalya (n=40), Istanbul (n=7), Izmir (37), Diyarbakir (n=15), Van (n=12), Trabzon (n=48)] selected as representatives of the seven different geographical regions of Turkey. Methicillin resistance was determined by cefoxitin disk diffusion in the hospitals where the strains were isolated and confirmed by oxacillin salt agar screening at the Refik Saydam National Public Health Agency. Screening for VISA and VRSA was conducted using the agar screening test and E-test. Susceptibility of the MRSA strains to other antibiotics was also determined by E-test method. None of the 260 MRSA strains were determined to be VRSA or VISA. All were susceptible to teicoplanin and linezolid, and susceptibility rates to daptomycin, tigecycline and quinupristin-dalfopristin were 99.6%, 96.9%, and 95%, respectively. Absence of VISA and VRSA among the MRSA strains surveyed currently seemed hopeful, however, continuous surveillance is necessary. In order to prevent the development of VISA and VRSA strains the use of linezolid, tigecycline, quinupristin-dalfopristin and daptomycin should be encouraged as alternative agents of treatment of MRSA infections.

    Response of Silage Maize (Zea mays L.) to Nitrogen Fertilizer after Different Crops in a Semi Arid Environment
    (Tubitak Scientific & Technological Research Council Turkey, 2008) Gul, Ismail; Yildirim, Mehmet; Akinci, Cuma; Doran, Ilhan; Kilic, Hasan
    The use of legume crops in maize rotation systems may decrease the need for nitrogen (N) fertilization and increase total output. The effect of previous crops (wheat, barley, lentil, Hungarian vetch, and fallow) and different N fertilization rates (0, 120, 160, 200, and 240 kg of N ha(-1)) on yield and N content of silage maize (Zea mays L.) were evaluated under irrigated conditions in Diyarbakir, Turkey, during the 1999-2000, 2000-2001, and 2001-2002 growing seasons. Dry matter yield varied between 10,068.2 and 16,480.4 kg ha(-1). It was determined that Hungarian vetch was a suitable rotation crop, and that 200 kg of N ha(-1) was the best N fertilization rate for silage maize production across years and N rates. Moreover, according to the previous crop x N fertilization rate interaction, the highest dry matter yield was obtained from 240 kg of N ha(-1) after barley. Silage maize following Hungarian vetch in rotation did not respond to the application of more than 120 kg of N ha(-1), in terms of dry matter and N yields, while in barley-maize and wheat-maize these 2 parameters increased in response to every level of N fertilization applied. Additionally, fallow-maize and wheat-maize did not respond to the application of more than 200 kg of N ha(-1). The legumes showed potential as previous crops that could replace fallow and cereals in silage maize production by reducing the amount of N fertilizer used on silage maize without significantly decreasing dry matter and N yield. Nonetheless, the cereals demonstrated high dry matter yields, based on annual production. According to regression analysis, the highest dry matter and N yields were obtained from the application of 198, 254, 211, 80, and 210 kg of N ha(-1) after previous crops of wheat, barley, lentil, Hungarian vetch, and fallow, respectively.
