Publication Effects of chemical and organic fertilizer treatments on yield and quality traits of industrial tomato(Namik Kemal Üniversitesi, 2021-05-01) Turhan, Ahmet; Özmen, Neşe; TURHAN, AHMET; ÖZMEN, NEŞE; Mustafakemalpaşa Meslek Yüksekokulu; Gıda İşleme Bölümü; 0000-0002-1976-8082; AAG-5956-2021; AAG-5889-2021Increasing plant production by protecting the environment is one of the main goals of today's agriculture. On the other hand, the use of both inorganic and organic fertilizers is becoming increasingly extensive. This study was carried out in field conditions to determine the effects of organic and inorganic fertilization on yield and quality characteristics of industrial tomato (Solanum lycopersicum L., cv. Heinz 1015 F-1). For this purpose, contents of fruit total soluble solid contents, total dry matter, titratable acidity, lycopene, total carotenoids, and vitamin C contents and yield (marketable yield and paste yield) were determined. Experiments were conducted in randomized blocks design with 3 replications. There were seven experimental treatments as of control (without fertilizer), chemical fertilizer, organic farmyard manure, sheep manure, poultry manure, vermicompost and leonardite. According to the research results, the highest marketable and tomato paste yield were obtained from chemical fertilizer, followed by organic fertilizers and the lowest values were obtained from the control. As compared to chemical fertilizers, organic fertilizers influenced fruit quality attributes more positively. The highest lycopene, total carotenoid and vitamin C contents were obtained from organic fertilizers, especially from poultry manure. Fruit soluble solids and dry matter contents, important processing traits assumed by tomato industry, were obtained from poultry manure treatments. Fruits from leonardite-treated plants had considerably higher titratable acidity levels. Except for total dry matter and titratable acidity, lowest values of quality parameters considered important in industrial tomatoes were obtained from unfertilized (control) plots. Present findings revealed that chemical fertilizers were essential for high and economic yield levels in tomato farming, but organic fertilizers should also be supplemented to improve tomato fruit quality attributes.Publication Influence of chloride on growth, fruit yield and quality parameters of processing pepper(Kahramanmaras Sutcu Imam Univ Rektorlugu, 2021-01-01) Turhan, Ahmet; Özmen, Neşe; TURHAN, AHMET; ÖZMEN, NEŞE; Mustafakemalpaşa Meslek Yüksekokulu; 0000-0002-1976-8082This study was carried out to investigate the effects of irrigation water containing different Cl- on plant growth parameters, fruit yield and quality characteristics of pepper (C. annuum L. cv. Postal Capija). Nutrient solutions containing Cl- concentrations were applied to processing pepper plants and effects of Cl- on growth parameters, fruit yield and quality traits, leaf water potential and chloride contents were determined. Greenhouse experiments were conducted with the Cl- concentrations [control (0.27), 1.5, 3.0, 4.5, 6.0, 7.5 and 15.0 mM] were applied to pepper plants. Plant height, fresh and dry weight, fruit yield and fruit weight, length and diameter were not affected by increasing Cl- concentrations up to 3.0 mM, but further increases in Cl- concentration negatively influenced this results. The greatest dry matter and soluble solids content were obtained from 3.0 and 4.5 mM Cl- treatments. Increasing Cl- concentration increased fruit acid content; the greatest acid content was from the greatest Cl- concentration. Increasing growing media Cl- concentration increased leaf Cl- accumulation and Cl- concentration >3.0 mM reduced leaf water potential. Research results showed that Cl- concentrations in irrigation water are important for efficient and economical pepper cultivation, and using water containing more than 3.0 mM chlorine will jeopardize yield and quality.Publication Response of red pepper (Capsicum annuum L.) to foliar applications of zinc(Taylor, 2021-02-21) Turhan, Ahmet; Kuşçu, Hayrettin; Özmen, Neşe; TURHAN, AHMET; KUŞÇU, HAYRETTİN; ÖZMEN, NEŞE; Mustafakemalpaşa Meslek Yüksekokulu; Gıda İşleme Bölümü; 0000-0002-1976-8082; 0000-0001-9600-7685; AAH-4682-2021; AAG-5889-2021; AAG-5956-2021An open-field study considering the responses of red pepper plants to foliar applications of zinc (Zn) was conducted with the aim to understand its effect on fresh fruit yield (FFY) and paste yield (PY), and some physical and quality properties of the fruits. Four different doses of Zn (control 0.0%, 0.05%, 0.10% and 0.20%) were applied from the plant leaves as zinc sulfate (ZnSO4.7H(2)O). The effect of Zn applications on plant height (PH) and crop canopy percentage (CCP) was in a positive direction. The longest plants were obtained from 0.10% Zn application. Treatments of 0.10% and 0.20% Zn positively affected the weight (FW), diameter (FD) and height (FH) of pepper fruits, significantly increased compared to control. The highest FFYs were obtained from 0.10% and 0.20% Zn applied plants. PY increased 33% in response to 0.10% Zn treatment when compared with control. The highest fruit dry matter (DM) was obtained from both applications (0.10% and 0.20% Zn), while the highest soluble solids content (SSC) was determined at 0.20% Zn application. These results indicate that foliar application of Zn could be considered for red pepper cultivation to improve plant development, yields and some quality properties, particularly in regions where Zn insufficiently is high.
