    DETERMINATION OF THE SILAGE QUALITY CHARACTERISTICS OF DIFFERENT SWITCHGRASS (PANICUM VIRGATUM L.) CULTIVARS
    (Aloki Applied Ecological Research And Forensic Inst Ltd, 2019) Elis, S.; Ozyazici, M. A.
    This study was carried out to determine the silage quality characteristics of some switchgrass (Panicum virgatum L.) cultivars. Kanlow, Shelter, Shawnee, BoMaster, Alamo, Trailblazer, Cave in Rock and Long Island cultivars of switchgrass constituted the plant material of the study. For silage purposes, the plants were harvested 10-15 days after reaching the flowering period. The harvested plants were allowed to ferment for 70 days. According to the results, the silage of switchgrass cultivars was statistically significantly at p<0.01 level for both physical and chemical properties. In the study, pH content, the dry matter, lactic acid, butyric acid, acetic acid, crude protein, acid detergent fiber, and neutral detergent fiber ratios of the silage of switchgrass cultivars varied between 3.84-4.86, 39.0-51.0%, 1.78-2.35%, 0.05-0.33%, 0.35-1.55%, 3.76-5.57%, 39.30-41.73%, and 70.96-75.41%, respectively. In terms of the Fleig score, it was determined that the quality of the silage obtained from switchgrass cultivars could be classified as very good. According to result, it was determined that BoMaster, Alamo, and Trailblazer cultivars, especially Long Island and Cave in Rock cultivars of switchgrass that came to the forefront in terms of silage quality, could be successfully used in silage production.

    DETERMINATION OF VEGETATION AND SOIL PROPERTIES OF THE FLOODPLAIN RANGELAND IN THE CONTINENTAL CLIMATE ZONE OF TURKEY
    (Corvinus Univ Budapest, 2019) Demirhan, E.; Ozyazici, M. A.
    This study was conducted in May 2017 to investigate vegetation and soil properties of a floodplain rangeland, which is located in the continental climate zone of Turkey. In the study, vegetation surveys were performed in the rangeland areas with two different slope degrees (0-1% and 2-5%), and the Modified Wheel Point method with loop was used in vegetation measurements. A total of 23 different species belonging to 20 genera from 9 families, were identified in the rangeland where vegetation surveys were conducted. It was determined that 2 of the identified species were decreaser, 2 of them were increaser, and 19 of them were invasive species. The plant cover ratio of the studied rangeland area where the study was conducted covered with the plant was 76.87%. In general, the ratio of the Poaceae in the botanical composition of the examined rangeland was 35.32%, the ratio of legumes was 28.60%, and the ratio of other families was 36.08%. The examined rangeland soils had medium structure, mild alkaline character, and no salinity problem. It was determined that organic matter, available phosphorus and potassium content of the rangeland's moderately calcareous soils were higher in the base areas than in the slightly inclined areas.

    The Effect of Salinity on Root Architecture in Forage Pea (Pisum sativum ssp. arvense L.)
    (Agricultural Research Communication Centre, 2021) Acikbas, S.; Ozyazici, M. A.; Bektas, H.
    Background: Plants face different abiotic stresses such as salinity that affect their normal development, growth and survival. Forage pea is an important legume crop for herbage production in ruminants. Its agronomy requires high levels of irrigation and fertilization. This study aimed to evaluate the effect of salinity on seedling root system development in forage pea under semi-hydroponics conditions. Methods: Different treatment of NaCl doses (0, 50, 100, 150, 200, 250 and 300 mM) on root architecture was investigated in two different forage pea cultivars (Livioletta and Ulubatli) with contrasting root structures under controlled conditions. The experimental design was completely randomized design with three replications and nine plants per replication. Result: Salinity affects root and shoot development differently on these cultivars. Despite the salinity, Livioletta produced more shoot (0.71 g) and root biomass (0.30 g) compared to Ulubatli (0.52 g and 0.25 g for Root and Shoot biomass, respectively) at 150 mM and all other salinity levels. Livioletta developed a better root system and tolerated salt to a higher dose than Ulubatli. Understanding root system responses of forage pea cultivars may allow breeding and selecting salinity tolerant cultivars with better rooting potential.
