    Comparison of agricultural characteristics of some triticale (X-triticosecale Wittmack) and barley (Hordeum vulgare) cultivars in Diyarbakir ecological conditions
    (Gaurav Soc Agricultural Research Information Centre-Aric, 2009) Aydin, A. L. P.
    This research was conducted to compare yield, yield and quality characteristics of triticale and barley cultivars in Diyarbakyr ecological conditions in Applying Research Farm, Faculty of Agriculture, University of Dicle during 2001-02 and 2002-03 growing seasons as randomized complete block design with three replications. Tatlycak-97, Karma-2000, Presto, Melez-2001 and Tacettinbey triticale cultivars and Erginel-90 and Kyral-97 barley cultivars were used as material in this research. According to the results as average of two years, statistically significant differences were found between cultivars in terms of agronomical traits such as plant height (104.66 cm in triticale and 100.51 cm in barley), the number of tillers per plant (3.14 in triticale and S. 14 in barley), days to heading (185.60 in triticale and 157.42 in barley), spike lengths (10.60 cm in triticale and 6.23 cm in barley), the number of grains per spike (41.27 in triticale and 44.23 in barley), grain yields (3515.7 kg/ha in triticale and 3055.7 kg/ha in barley); quality traits such as 1000-grain weight (37.13 g in triticale and 34.73 g in barley), protein percentage (11.25% in triticale and 9.68% in barley) and feeding traits such as fresh herbage yields (12508.7 kg/ha in triticale and 10569.4 kg/ha in barley) and dry herbage yields (3341.4 kg/ha in triticale and 2124.2 kg/ha in barley) in this research. It was concluded that Melez-2001 cultivar better adapted on account of grain yield and grain quality to regional conditions in triticale cultivation, Presto triticale cultivar was earlier. Because Tacettinbey and Tatlycak-97 cultivars showed high values with regard to fresh and dry herbage yields between both triticale and barley cultivars, they were found important as alternative cereal plants for animal feeding in this region. These cultivars can be expected to become widespread in areas where wheat and barley could not be grown economically.

    Determination of some agronomical characteristics and Ochratoxin-A level of Karacadag rice (Oryza sativa L.) in Diyarbakir ecological conditions, Turkey
    (Academic Journals, 2010) Aydin, A. L. P.; Yesilmen, Simten; Vural, Aydin; Guran, H. Sahan
    This study was conducted to determine yield, quality and Ochratoxin-A level of Karacadag rice local varieties grown widely in Karacadag ecological conditions of Southeast Anatolian Region and to compare with some commercial rice varieties during 2006 and 2007. In the study, total 12 rice genotypes consisting of 10 local varieties and 2 cultivars from foreign origin were used as material. Statistically the differences among the genotypes for all the characters were highly significant. The longest plants of 99.50 cm were recorded in Karacadag landrace No. 1 location with 10.47 tillers per plant, 7.82 panicles per plant and biological yields of 285.10 g plant(-1). Whereas, cv. Ribe showed 99.52 grains per panicle, cv. Baldo had 2.686 g grain yield per panicle and 5662.2 kg ha(-1) grain yield per unit area. Unbroken rice output rate of all rice landraces was higher compared to breeding cultivars. No 3 and 8 of Karacadag rice samples; which showed superior values in terms of plant height, number of tillers per plant and grain yield. It was concluded that these Karacadag rice landraces can contribute in obtaining of high yielded cultivars. That air temperature of Southeast Anatolian Region reached about 40 degrees C at booting stage lead to high spikelet sterility, but yield differences among landraces and breeding cultivars could be eliminated with great number of panicles per plant. All rice and white milled rice samples in this study were analysed in respect of Ochratoxin-A with ELISA test. It was found that ochratoxin-A level in samples from Odabasi-Cermik and Mehmediyan-Kocakoy locations were higher compared to samples taken from other locations. In general, the samples were found suitable to Turkish Food Codex and European Union (EU) regulations
