    A COMPARATIVE STUDY OF YIELD AND QUALITY OF LOCAL KARACADAG AND OSMANCIK-97 IN CONVENTIONAL AND ORGANIC AGRICULTURAL CONDITIONS
    (Bangladesh Botanical Soc, 2019) Kahraman, Serif; Alp, Aydin
    The work was carried out to compare the yield and quality of local Karacadag rice variety with the Osmancik-97 in conventional and organic agriculture conditions. In the organic agricultural conditions higher values were obtained compared to conventional conditions. Flowering took 82.6 days, 1000-kernel weight (31.38 g) and non-fractured rice yield were 61.75%. Local Karacadag rice variety under the organic conditions showed significantly higher values compared to Osmancik-97 breeding variety took 87.3 days for flowering, 128.2 days for ripening days. Plant height (84.1 cm), number of tillering in plants (2.82), number of bunches in the m(2) (369.3), kernel number of bunch (56.5), bunch length (15.9 cm), biological yield (13440 kg/ha), yield for unit area (4681 kg/ha) and non-fractured rice yield (64.7%) were observed. While there was no difference between the two rice varieties with regards to the kernel weight of bunch. Local Karacadag variety proved its ability to adapt to the ecological conditions of the region. It is suggested that the cultivation of the Karacadag rice cultivar in organic agriculture conditions may be expanded in the region.

    THE COMPARISON OF AGRICULTURAL AND TECHNOLOGICAL PROPERTIES OF SOME CORN (ZEA MAYS L.) VARIETIES AS THE MAIN AND SECOND CROP
    (Parlar Scientific Publications (P S P), 2018) Alp, Aydin; Kahraman, Serif
    No doubt, investigating the possibility of cultivating maize in two different periods without a decline in yield and quality of the maize will contribute to the cultivation of maize in the region. In this study, the agricultural and technological properties of grain maize varieties grown as main and second crop were investigated. The study was conducted in the research and application field of GAP International Agricultural Research and Educational Center between 2014-2015 as three replicates in Randomized Blocks Trial Design. Different 15 grain maize varieties that were compatible with the Southeastern Anatolia Region climatic conditions which had different vegetation periods and which were provided from different seed institutes were used as the material in the study. In terms of two year average values in the main and second cropping periods; significant differences according to 1 % among the maize varieties in silking periods (82.4-64.9 day), first ear height (99.4-102.6 cm), stem thickness (21.9-23.50 mm), ear length (21.0-21.4 cm), ear thickness (46.58-48.97 mm), number of ear per plant (1.0321.039 number), kernel/ear (% 85.58-81.32), moisture (% 15.64-25.17). It was determined that a plant grain yield was 188.59 g in main cropping, 176.3 g in second cropping. In terms of unit area grain yield, the average of maize varieties was found significantly different according to 5%; the average unit area yield was determined as 138.88 kg/ha in main cropping and 126.60 kg/ha in second cropping. As a conclusion, it was determined that, PR31D24, Sy Radioso, Suertoda, 72May80, P.31G98, Katone and Sy Lucroso varieties had superior values in the main crop, and Katone, PR31D24 and Kerbanis varieties had superior values in the second crop in Diyarbakir climatic conditions in terms of yield and technological properties.

    DETERMINATION OF COMPETITION CAPACITY OF LOCAL KARACADAG AND OSMANCIK-97 RICE VARIETY AGAINST SOME WEEDS
    (Bangladesh Botanical Soc, 2017) Alp, Aydin; Celik, Sadettin; Kaya, Burhan
    In the first part the effects of aqueous extracts of leaf, straw, hull and seed of 7 different weed species on germination of local Karacadag and Osmancik-97 rice seeds was investigated. In the second part, Karacadag and Osmancik-97 rice seeds were sown together with weed seeds to plots, and it was determined effects of varied weed species on germination, root, seedling, leaves and grain yield of rice varieties in field conditions. As a result of the findings; aqueous extracts of Echinochloa crus-galli L. Beauv, E. oryzoides(Ard.) Fritsch., Amaranthus retroflexus L. and Physalis peruviana L. were found to be the weeds which inhibit the germination of both rice seeds the most in both laboratory and field conditions.

    The evaluation of durum wheat landraces for resistance to wheat yellow rust (Puccinia striiformis f. sp tritici) in the Southeastern Anatolia Region, Turkey
    (Wfl Publ, 2009) Alp, Aydin; Sagir, Abuzer
    Fifty wheat samples collected from 11 different durum wheat landraces produced in the central district and villages of Diyarbakir province were used as study materials. Suspension, prepared as 352,000 spores per ml by using the spores composed of a mixture of yellow rust (Puccinia striiformis f. sp. tritici) species provided by the Field Crops Central Research Institute, was injected into plant tissue in the pre-earing stage during the 2004-2005 and 2005-2006 growing seasons. Of the 50 durum wheat landrace samples 15 used in the study were classified as resistant to yellow rust, 19 as semi-resistant and 14 as semi-susceptible. Moreover, it was also found that one sample from the A sure landrace was in the susceptible group with the highest rust intensity of 61.68% while one sample from the Ruto landrace was found to be in the immune group with an intensity of 0%.

    Microbiological and physico-chemical quality properties of wheat varieties in Turkey
    (Asian Journal Of Chemistry, 2008) Alp, Aydin; Vural, Aydin; Erkant, Mehmet Emin; Yesilmen, Simten
    In this study, the microbiological and physico-chemical quality properties of 27 different wheat cultivars produced in Turkey were determined. The means total aerob mesophilic bacteria (TAMB), coliforms, Bacillus cereus, Staphylococcus aureus, mould and yeast counts were found 4.5 x 10(3) cfu/g, 3.1 x 10(1) cfu/g, 3.5 x 10(1) cfu/g, 1.6 x 10(1) cfu/g, 7.1 x 10(1) cfu/g and 8.1 x 10(1) cfu/g at wheat samples, respectively. While coliform, B.cereus, S. aureus, mould and yeast rates were detected 37.04, 18.52, 22.22, 40.74 and 37.04 %, respectively; in none of the samples, Salmonella spp., Escherichia coli and Clostridium perfringes were not determined. Dry matter, moisture, protein and ash means in wheat samples were calculated as 92.38, 7.62, 11.30 and 1.65 %. It was seen that the quality of wheat cultivars might change regarding production, storage, climate and other regional conditions. It is thought that it would be possible to get quality and healthy product with good production and protection techniques in all stages from harvest to the last product.

    TILLAGE EFFECTS ON SUNFLOWER (HELIANTHUS ANNUUS, L.) EMERGENCE, YIELD, QUALITY, AND FUEL CONSUMPTION IN DOUBLE CROPPING SYSTEM
    (Univ Zagreb, Fac Agriculture, 2008) Sessiz, Abdullah; Sogut, Tahsin; Alp, Aydin; Esgici, Resat
    The relation between crop growing and soil tillage treatment are play important role in agricultural production. Soils under conventional tillage (CT) generally have lower bulk density and associated higher total porosity within the plough layer than under no tillage (NT). No-till farming can reduce soil erosion, conserve soil moisture and minimize labor and fuel consumption. The aim of this study were to investigate the effects of conventional, reduced and notillage methods on soil physical properties, sunflower yield and yield components, protein and oil content and fuel consumption in Southeastern of Turkey. Six tillage methods for the second crop sunflower were tested and compared each other within after lentil harvesting at 2003 and 2004 years in a clay loam soil. According to results, the first year, the bulk density had decreased from 1.29 to 1.09 g cm(-3), the second year the delta b had decreased from 1.41 to 1.23 g cm-3. Differences between years and tillage methods in terms of yield were found significant (p<0.05). However, no differences were found between the NT and CT. There were also no significance differences in content of protein, oil and ash among six tillage methods. The highest fuel consumption was measured in conventional method (CT) whereas the lowest value was found in direct seeding method as 33.48 L ha(-1) and 6.6 L ha(-1,) respectively.
