Öğe Comparison of Quality and Yield Components of Peanut Market Types Using PCA(Kahramanmaras Sutcu Imam Univ Rektorlugu, 2023) Sahin, Cenk Burak; Yilmaz, Mustafa; Yildiz, Resat; Isler, NecmiThe aim of this study was to compare of agronomic and quality parameters of peanut varieties (Arachis hypogea L.) grown as main crop in Mediterranean Region of Turkiye. Principal component analysis (PCA) was used for evaluating the results of varieties. Field experiments were conducted over during the main crop seasons of the years 2018 and 2019. The experiment was designed as randomized complete block design (RCBD) with three replications. Runner (Georgia Green), Spanish (Florispan) and Virginia market types (Sultan, Brantley, BATEM-Cihangir, BATEM-5025, Arioglu-2003, Halisbey, NC-7, Flower-22, Wilson, NC-V-11, Com, Osmaniye-2005, Gazipasa) peanut varieties were used as plant materials. According to PCA two-year average, PC1, PC2 and PC3 explained about 80% in joined years. Georgia Green could be recommended to achieve high efficiency shelling percentage (73.96%) and pod yield (497.24 kg da-1), and Arioglu-2003 could be the optimum selection on the first quality pod ratio (80.28%) and protein content (28.76%).Öğe DETERMINATION OF OIL QUALITY AND FATTY ACID COMPOSITIONS OF SOME PEANUT (Arachis hypogaea L.) GENOTYPES GROWN IN MEDITERRANEAN REGION(Soc Field Crop Sci, 2022) Sahin, Cenk Burak; Yilmaz, Mustafa; Isler, NecmiThis study was conducted to determine the performance of fifteen peanut lines from India and four peanut varieties (NC-7, Halisbey, Sultan and BATEM-5025) registered in Turkey. The present study was carried out in Osmaniye, which is under Mediterranean climate conditions as main crop season in 2020 and 2021. The experimental design was randomized complete block design (RCBD) with three replications. The highest oil content of peanut was observed in ICGV 10193 (52.16%+/- 0.34), followed by ICGV 10179 (51.58%+/- 0.35) and ICGV 16013 (51.47%+/- 0.35). However, Oleic Acid / Linoleic Acid (OIL) ratio and iodine value are both indicators of peanut shelf life and oil stability. ICGV 15074 and ICGV 16013 came to forefront with high 0/L ratio (9.46 +/- 1.46, 5.44 +/- 0.61) and low iodine value (72.68 +/- 0.60, 76.41 +/- 0.69), respectively. As a result of the study, it was concluded that some Indian peanut lines, mentioned above, can be proper to include breeding program due to their higher oil and oleic acid contents.Öğe Determination of Oil Quality Factors and Fatty Acid Compositions of Some Peanut Varieties(Univ Namik Kemal, 2023) Yilmaz, Mustafa; Sahin, Cenk Burak; Yildiz, Resat; Isler, NecmiThe aim of this study was to determine the oil properties and fatty acid compositions of peanut cultivars (Arachis hypogaea L.) grown as the main crop in the Eastern Mediterranean transition zone of Turkey. The field experiment was conducted at the Oil Seed Research Institute experiment area in the main crop seasons of 2018 and 2019. The experiment was designed according to the randomized complete block design (RCBD) with three replications. Oil ratio, saturated fatty acids (palmitic acid, stearic acid), unsaturated fatty acids (oleic acid, linoleic acid), iodine value, and oleic/linoleic acid ratios were investigated in the experiment. Runner (Georgia Green), Spanish (Florispan), and Virginia market types (Sultan, Brantley, BATEM-Cihangir, BATEM-5025, Arioglu-2003, Halisbey, NC-7, Flower-22, Wilson, NC-V- 11, Com, Osmaniye-2005, Gazipasa) varieties were used as plant materials. As a result of this study, NC-V- 11 (52.23%) cultivar with the highest oil content was determined, followed by Florispan (52.16%), Brantley (52.10%), and Gerogia Green (51.54%). The lowest oil content was obtained from BATEM-Cihangir (44.57%) variety. Brantley variety was found to have the least palmitic acid ratio with 8.04%, while Florispan variety was found the highest with 12.24%. In terms of stearic acid ratios, the lowest value (1.38%) was determined in Com variety, while the highest value (2.91%) was found in Brantley variety. Brantley variety was found to have the highest oleic acid content (71.83%), which is one of the unsaturated fatty acids. Florispan variety had the lowest oleic acid content (43.70%). While Brantley variety had the lowest linoleic acid ratio (9.78%), it was determined that Com variety had the highest linoleic acid ratio (35.77%). The iodine value varied between 78.71-100.71, the lowest value was in Brantley and the highest value was in Com. The oleic acid/linoleic acid ratio was determined to vary between 1.22 and 7.35, the lowest value was in Florispan and the highest value was in Brantley. As a result of the research, it was determined that the variety with the highest oleic acid ratio in the Eastern Mediterranean Transition Zone was Brantley. Peanuts with high oleic acid content are preferred by producers and consumers because they have good quality and extend the shelf life of products producing with them.Öğe Effects of Foliar Fertilizer Applications on Leaf Area, Chlorophyll and Nutritional Content at Different Growth Stages of Soybean(Univ Namik Kemal, 2022) Sahin, Cenk Burak; Isler, NecmiPlants need all plant nutrition elements to be available and adequate level in soil for optimum growth and yield production. The uptake of macro and micro nutrients by plants is limited or they can not be beneficial for plants in calcareous soils with high pH such as being in Mediterranean Region. In such situations, management strategies such as foliar spray can be useful to benefit of plants from them particularly under soil-limed condition with restricted micronutrients uptake. In this study, it was aimed to evaluate the effects of foliar-applied zinc and iron on chlorophyll content, leaf area index (LAI) and chemical composition of soybean (Glycine max L.) at different growth stages. Field experiments were conducted over during the second crop seasons of the years 2018 and 2019 under the conditions of Hatay Province. The experiment was designed as split-split plot design with three replications. Varieties (Arisoy, Bravo, Nazlican) were placed in main plots, growth stages (V3, R1, R3) in subplots and foliar fertilizers (control, zinc, iron, zinc + iron) in sub-sub-plots. Foliar application of iron and zinc increased chlorophyll content and LAI values at different stages of growth in contrast to control (untreated) groups. The highest SPAD value (36.03) was obtained from Nazlican x R3 x Zn + Fe treatment and the highest LAI (7.57) was obtained from Bravo x V3 x Fe treatment. Generally, the higher results of SPAD value were observed in reproductive stages while the higher results of LAI were observed in vegetative stages. Leaf zinc and iron accumulations were higher in reproductive stages. As a result of this study, it was observed that micro nutrients needed by soybean plant can be supplied with foliar applications in calcareous soils.Öğe Foliar Applied Zinc and Iron Effects on Yield and Yield Components of Soybean: Determination by PCA Analysis(Taylor & Francis Inc, 2021) Sahin, Cenk Burak; Isler, NecmiIn this study, the effects of zinc and iron treatments in different growth stages on yield and yield components of soybean (Glycine max L.) plants were evaluated by principal component analysis (PCA). Field experiments were conducted over during the second crop seasons of the years 2018 and 2019. The experiment was designed as a split-split plot design with three replications. Three varieties of Arisoy, Bravo, and Nazlican were placed in main plots, growth stages of the soybean (V3, R1, R3) in subplots and foliar fertilizers (Zn, Fe, Zn+Fe) in sub-sub plots. Variance analysis revealed that all parameters were significant except the first pod length (2019) and 1000-seed weight (2019). PC1, PC2, and PC3 explained 84.50% of the total variation in 2018 and 86.10% in 2019. Zn + Fe mixture treatment could be recommended for foliar spray because the highest seed yields were obtained from Zn + Fe in both years.Öğe The impact of foliar applied zinc and iron on quality of soybean(Taylor & Francis Inc, 2023) Sahin, Cenk Burak; Isler, NecmiFor optimum growth and yield production, plants need all soil minerals to be available in adequate level, and unsuitable soil conditions can restrict root's ability for uptake of minerals nutrient. For that matter, foliar sprays can be the best option for plants to benefit from nutrients. Field experiments with split-split plot design with three replications were conducted in 2018 and 2019 to determine the effects of foliar spraying zinc and iron treatments on some quality parameters of soybean (Glycine max L.) plants under calcareous soil with high pH conditions. Varieties (Arisoy, Bravo, Nazlican) were placed in main plots, growth stages of the soybean (V3, R1, R3) in sub plots and foliar fertilizers (Zn, Fe, Zn + Fe) in sub-sub plots. Foliar application of iron and zinc increased oil and protein content per soybean seed at different stages of growth in contrast to control (non-fertilizers) groups. The highest protein contents (33.61%) and oil contents (22.02%) were obtained from Zn treatment in both years. However, Zn + Fe mixture (102.25 kg da(-1)) was more efficient on oil yield in both years. It was observed that two-year average of polyunsaturated fatty acids was 58.93% (linoleic 50.13%; linolenic 8.80%), monounsaturated fatty acid was 24.83% (oleic), and saturated fatty acids were 14.68% (palmitic 11.82%; stearic 2.86%). Foliar Zn + Fe mixture spraying can be recommended to get high oil yield, and foliar Zn spraying for oil and protein contents from soybean based on this study.
