Publication Investigation of polycyclic aromatic hydrocarbons (PAHs) uptake by cucurbita pepo under exhaust gas loading(Taylor & Francis Ltd, 2022-02-21) Cihangir, Perihan; Durmuş, Hafize; Taş, Birol; Cindoruk, S. Sıddık; Cihangir, Perihan; Durmuş, Hafize; TAŞ, BİROL; CİNDORUK, SABAHATTİN SIDDIK; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/Çevre Mühendisliği Bölümü.; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Tarla Bitkileri Bölümü.; 0000-0001-7536-0332; EPC-0182-2022; IKM-6534-2023; EBF-7938-2022; GBB-7012-2022It was aimed to compare the uptake of PAHs (Polycyclic aromatic hydrocarbon) by Cucurbita pepo fruits exposed to exhaust gas or not in a greenhouse chamber. Cucurbita pepo vegetable was grown in two greenhouses, which were formed as control group and experimental group. The experimental group greenhouse was regularly exposed to exhaust gas for a certain period, no intervention was made to the control group. PAHs were measured in grown Cucurbita pepo samples and indoor air of greenhouse by passive air sampler (PAS). The average n-ary sumation (16)PAH concentration in Cucurbita pepo in the experimental group (exposed to exhaust gas) was 191.5 ng/g, compared with 124.8 ng/g in the control group (not exposed). The nearness of the vegetable to exhaust gas source were effective on the PAH levels. A significantly positive relationship (p < 0.05) was observed in PAH concentration between Cucurbita pepo and indoor air. It was found that PAH levels measured in the Cucurbita pepo vegetable were increased in proportion to PAH exposure, but this amount tended to decrease in the Cucurbita pepo growing sufficiently. Benzo(a)pyrene had the highest toxic equivalence value in health risk assessment calculations. A negative effect of excess foliation on plant growth rather than fruit production was observed under exhaust gas exposure.Publication Effects of nitrogen and zinc fertilizers on grain yield and some yield components of pehlivan(Asian Journal of Chemistry, 2008-11-01) Taş, Birol; Çelik, Necmettin; TAŞ, BİROL; Çelik, Necmettin; AAG-7375-2021; JBS-6560-2023This research was performed to determine the effect of which wheat will have on yield and some yield components by applying two importants elements of which many researchers investigated only one of them (only N or only Zn). It was carried out on experimental areas of Uludag University Agricultural Faculty where Zn deficiency was present. As an experimental material, Pehlivan, an important bread wheat, was used for two cultivation periods. The experiment area was established in a randomized design with three replicates on 1.2 x 5 m = 6 m(2). In this experiment, five different zinc doses (Z(0): 0 g da(-1), Z(1): 100 g da(-1), Z(2): 150 g da(-1), Z(3): 200 g da(-1), Z(4): 250 g da(-1))and four different nitrogen doses (N-0: 0 kg da(-1), N-5: 5 kg da(-1), N-10: 10 kg da(-1), N-15: 15 kg da(-1)) were applied. As a result, it was determined that Zn is of no significant effect on plant height, seed number pers pike, 1000-seed weight and yield. However, extremely positive results were obtained in combinations in which Zn forms with nitrogen. The best results in terms of plant height were obtained in Zn2N3, seed number per spike in Zn3N10, 1000-seed weight in Zn0N15, respectively. As to yield, average Z(3)N(10), Z(3)N(10), Z(4)N(5), Z(4)N(10) and Z(4)N(15) combinations were over 700 kg da(-1).Publication Effect of different doses of nitrogen fertilizer on yield and yield concentration of two-rowed barley cultivars(Asian Journal of Chemistry, 2008-04-01) Çelik, Necmettin; Taş, Birol; Çelik, Necmettin; TAŞ, BİROL; Uludağ Üniversitesi/Teknik Bilimler Meslek Yüksekokulu.; JBS-6560-2023; AAG-7375-2021The research was conducted in the experimental field of Department of Field Crops, Faculty of Agriculture, Uludag University, Bursa, Turkey. Totally ten cultivars were examined for two years (Angora, Caminant, Goldie, Viva, Jubilant, Compact, Orbit, Kaya, Sladoran and Balkan-96). The experiment area was established in a randomized design with three replicates having 500 spikes m(-2) on 1.2 x 5 m = 6 m(2). Pure nitrogen dose (33 % NH4NO3-) was applied 0 kg N da(-1) (N-0), 5 kg N da(-1) (N-5), 10 kg N da(-1) (N-10), 15 kg N da(-1) (N-15) and 20 kg N da(-1) (N-20) to each cultivar. It was found that grain number per spike and yield of cultivars increased until N-10, 1000-grain weight of the cultivars increased until N-15 application but following the application of N-20, there was a decrease in the above-mentioned characteristics. However, increasing nitrogen doses increased plant heights up to N-20 doses including N-20 but it was observed that plant logging occurred in some cultivar. It was determined that there was a negative correlation between yield and plant height and a positive correlation between yield-and grain number per spike.Publication Effect of commercial and organic fertilisers on some heavy metal contents of semolina(Scibulcom, 2015-01-01) Taş, Birol; TAŞ, BİROL; Uludağ Üniversitesi/Teknik Bilimler Meslek Yüksekokulu; JBS-6560-2023; AAG-7375-2021Almost all nutrient elements include heavy metals in varying amounts. It is already known that the practices in plant production (such as irrigation, fertilisers, applying pesticides, etc.) have effects on the heavy metal contents of the crops that are grown in that field. For this reason, the effects of two growing techniques (Organic Farming System and Commercial Fanning System) on the heavy metal contents in semolina have been examined in this study, because many food products produced from semolina have important place in human nutrition. The study was planned in 3 replications according to the Randomised Complete Block Design. No agricultural production had been performed in the field where the study was conducted. The Kiziltan-91, Mirzabey 2000, Eminbey, Cakmak-79 and Kunduru 1149 varieties were used as the experiment materials. The varieties were grown in two different styles as Conventional Farming System (CFS) and Organic Farming System (OFS) style. The varieties were planted in 7 m(2) parcels by hand with a '5 m length x 1.4 m width; 20 cm row space, 8 rows' design. While the Cd amount was almost the same in all soil types, the Cr, Ni and Pb amounts gave the highest values in the soil types where CFS was applied. The amount of Cu and Zn was found to be the highest in the soil type where OFS was applied. In the semolina samples, statistically important differences were detected between the values found in OFS and CFS, except for the Cr.
