    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.
