    Effects of different nitrogen doses on forage yield of some sweet sorghum [sorghum bicolor var. saccharatum (l.) mohlenb.] varieties
    (Bursa Uludağ Üniversitesi, 2022-06-01) Yönter, Fikret; Taşkın, Sinem Zere; Bilgili, Uğur; Ziraat Fakültesi; Tarla Bitkileri Bölümü; 0000-0002-4813-1611; 0000-0002-2243-2993; 0000-0003-0801-7678
    This study was carried out to determine the forage production potentials of different sweet sorghum genotypes under Mediterranean-type climate conditions as the second crop in 2020. Three different sweet sorghum genotypes (Erdurmuş, Uzun varieties, and M81-E line) and four nitrogen doses (0.0, 7.5 12.5, 17.5 kg da-1) were used in this research. The experimental design was a randomized complete block with three replications. Some parameters such as plant height, stem diameter, plant number per m2, leaf number, leaf and stem ratio, forage yield, and dry matter yield of sweet sorghum genotiyps were investigated in the experiment. According to the results, M81-E gave the highest values in terms of stem diameter, leaf number, forage yield, and dry matter yield parameter compared to other genotypes. Forage yield values of the genotypes were between 2969.9 and 5815.0 kg da-1 and dry matter yield values were 1105.7 and 2837.8 kg da-1. Forage yield values vary between 2920.1 and 4674.6 kg da-1 for the nitrogen doses. The highest forage yield was obtained at 12.5 and 17.5 kg da-1 nitrogen doses, which were in the same statistical group. Fertilization can be made with a 12.5 kg da-1 nitrogen dose in sweet sorghum due to the negative environmental effects of chemical fertilizers.

    Evaluation of Gebze-Orhangazi-İzmir Highway’s landscape plants
    (Bursa Uludağ Üniversitesi, 2022-06-01) Özkan, Esra; Zencirkıran, Murat; Ziraat Fakültesi; Peyzaj Mimarlığı Bölümü Bölümü; 0000-0003-3325-0391; 0000-0003-0051-8937
    In this study, Gebze-Orhangazi-İzmir Highway, which is the longest completed highway in Turkey with a length of 426 km, landscape plants have been examined in terms of ecological, aesthetic and suitability criteria. Gebze-Orhangazi-İzmir Highway consists of 7 sections, namely Gebze-Orhangazi, Orhangazi-Bursa, Bursa-Susurluk, Susurluk-Balıkesir, Balıkesir-Kırkağaç, Kırkağaç-Manisa, and Manisa-İzmir. It has been determined that 107 landscape plant taxa are used in the whole study area. It has been determined that Gebze-Orhangazi section has the highest taxa diversity and Bursa-Susurluk section has the least taxa diversity. It is seen that a total of 6,144,974 plants are used in the whole highway. Of landscape plants which are used as taxa, 59.81% are exotic (foreign), 40.19% are natural (domestic). It has been found that 74.77% of them are resistant to frost, 63.55% of them are resistant to drought, and 37.38% of them are resistant to salinity. It is observed that 92.52% of the taxa are suitable for the highway landscape.

    Technical and economic analysis of electricity production with solar panels: Bursa example
    (Bursa Uludağ Üniversitesi, 2022-06-01) Biçen, Tuba; Vardar, Ali; Ziraat Fakültesi; Biyosistem Mühendisliği Bölümü; 0000-0001-6826-2494; 0000-0002-5741-8841
    Nowadays, technology is rapidly evolving. The overuse and adverse effects of fossil fuels have also accelerated the work in the field of renewable energy. Considering that the sun is an endless source of energy, it is inevitable to produce clean and sustainable power. In this case, the use of photovoltaic facilities by small and medium-sized enterprises is also economically effective. To this end, world states constitute various incentive mechanisms. Monocrystalline and polycrystalline panels are commonly used in photovoltaic plants. In this study, considering various incentive mechanisms samples were examined a photovoltaic plant in Turkey. In addition, the technical and economic analysis of electrical energy production from the photovoltaic solar power plant was conducted. In this study, technical and economic analysis of a 23 kW photovoltaic plant to be installed in small and medium enterprises in Bursa province, which is obtained from our country market, has been examined. From the technical point of view, the annual energy production obtained from the plant consisting of monocrystalline panels varied between 28081 kWhyear-1 and 32239 kWhyear-1 and the total energy production obtained during the economic life varied between 617838 kWhxyear-1 and 709250 kWhxyear-1. Annual energy generation from the plant consisting of polycrystalline panels was between 26209 kWhyear-1 and 31886 kWhyear-1 and the total energy production was between 524179 kWhxyear-1 and 637720 kWhyear-1 and less than the monocrystalline plant.
