Öğe Comparison of protein and oil concentration of soybean (Glycine max. Merr.) cultivars under main and second cropping systems(Mrs Pushpa Agarwal, 2006) Sogut, TahsinMaturity group (MG) II, III and IV soybean cultivars are shown the best adaptations in the conditions of southern Turkey. These cultivars generally can be sown from April (as a main crop) to July (as a second crop). The study was conducted to determine the effect of early and late planting dates on oil and protein concentration of soybean cultivars from different maturity groups in Diyarbakir conditions, during 2003 and 2004. It has been found that oil and protein concentrations were not affected significantly by planting dates. However, significant differences were observed among cultivars for protein concentration but not for oil concentration, thus a greater performance was seen in the cultivars from MG IV. Planting date x cultivar was significant for protein concentration and the protein concentration was found to be higher for Stressland (MG IV), Cisne (MG IV) and Macon (MG III) in the early planting (387, 383 and 381 g kg(-1), respectively). Similarly, Stressland has also the highest protein concentration in the late planting (390 g kg(-1)), whereas Amsoy 71 (MG II) has the lowest protein concentration in both planting dates.Öğe DETERMINATION OF SOME AGRONOMICAL CHARACTERISTICS AND ESSENTIAL OIL VARIATION IN DIFFERENT LOCAL Ocimum basilicum L. ECOTYPES UNDER SEMI-ARID CLIMATIC CONDITIONS(Wydawnictwo Akad Rolniczej W Lublinie, 2019) Kizil, Suleyman; Toncer, Ozlem; Sogut, Tahsin; Diraz, Emel; Karaman, SengulThe study aimed to determine agronomic characteristics and essential oil components of different basil ecotypes in semi-arid climatic conditions of South Eastern Anatolia, Diyarbakir, Turkey. Two-year harvest data about fresh and dry herb yield, dry leaf yield, essential oil content and its components from the plants of year 2015 and 2016 was analyzed in this study. Essential oil components were detected by gas chromatography/mass spectrometry (GC/MS). The resulting outcomes demonstrated that both ecotypes and harvests had important effects on fresh and dry herb, dry leaf yield and essential oil contents of sweet basil. The highest dry leaf yield was noted from green leafy ecotypes and from second harvest stage. Twenty-three constituents were detected in the essential oil of O. basilicum ecotypes. The main components of basil essential oil were linalool, methyl chavicol, neral, geranial and methyl cinnamate that differed according to ecotypes and harvests during experimental years 2015 and 2016. Purple leafy basil ecotypes were determined as linalool rich, while greenish leaf ecotypes were abundant in methyl chavicol. Silbe - green ecotype contains higher neral and geranial levels than the other ecotypes. It was concluded that basil plant could be grown successfully and harvested two or more times to prefer for maximum dry leaf yield and essential oil contents under semi-arid climatic conditions.Öğe Diurnal Variation Effects in Essential Oils of Wild Thyme (Thymbra spicata var. spicata L.) Under Cultivation Conditions(Taylor & Francis Ltd, 2016) Toncer, Ozlem; Karaman, Sengul; Diraz, Emel; Sogut, Tahsin; Kizil, SuleymanThere are many folkloric uses of Thymbra spicata var. spicata. Very few thyme species are found in semi-arid climatic conditions. T. spicata is one among these which is not under cultivation anywhere. The essential oil of plant possesses high antibacterial and antioxidant properties due to presence of large amounts of phenolic components. The aim of this study was to verify the variation of essential oil and its composition among 12 different populations harvested every three hours in a day (from 06: 00 to 21: 00 h) along 24 hours for Thymbra spicata var. spicata on May 30, 2013. The essential oil of samples were analysed by GC-MS/FID. The results, proved that essential oil content of T. spicata var. spicata harvested at different times varied and ranged 2.02 to 5.04 % such that the amount of essential oil content increased around noon (reaching its maximum at 12: 00 h) followed by a decrease in afternoon hours. The essential oil of T. spicata var. spicata was analysed and a total of 20 components representing 89.57-99.14 % of the oils were identified. The highest carvacrol content (70.87 %) was obtained from 6.00 h harvest and the lowest one was obtained at 12.00 h harvest as 66.36 %. Diurnal variation in p-cymene content was observed with maximum at 21: 00 h harvest (6.89 %) and minimum at 09: 00 h (5.02 %) harvest gamma-Terpinene content of essential oil was maximum when the plants were harvested at 12: 00 h, while the lowest content was found when harvested at 06: 00 h. Carvacrol content was highest in the morning harvest. The results suggest that high oil yield and carvacrol content vary according to the temperature and can be optimised by considering the harvest time of the plant during a day.Öğe Effect of main and second cropping on protein and oil concentrations and yield of groundnut (Arachis hypogaea L.)(Wfl Publ, 2009) Sogut, TahsinMaintaining yield potential and quality criteria of groundnut (Arachis hypogaea L.) are very important for late planted. This study was conducted to evaluate the protein and oil concentrations and productivity of different cultivars of groundnut grown in main and double cropping systems in the southern Turkey. Results indicated that cropping system significantly affected on characters examined. The highest pod yield was obtained when groundnut cultivars were planted as main crop in April. Across the two years study, the highest pod yield was obtained from cultivar NC 9 with 2589.4 kg ha(-1), about 781 kg ha(-1) more yielded than the plant introduction PI 269084. Oil and protein concentration and yield were affected from cropping systems. Results from the seed analyses indicated that oil concentration was higher in main cropping than in the double cropping, while protein concentration was lower in main cropping. Oil and protein yields appeared to change with cropping systems and in general, the main cropping increased oil and protein yield as a result of higher pod yield. The results of current study are consistent with the earlier reports that late planting dates negatively affect groundnut pod yield through reductions in all yield components except for protein concentration.Öğe EFFECT OF MAIN AND SECOND CROPPING ON SEED YIELD, OIL AND PROTEIN CONTENT OF SESAME (Sesamum indicum L.) GENOTYPES(Soc Field Crop Sci, 2009) Sogut, TahsinDouble-cropping of sesame (Sesamum indicum L.) with small grains has been quite successful across the southeastern Turkey. However, producers in this region use planting dates ranging from early May as main crop (normal) through late June as second crop (late). We investigated the effect of the two sowing periods (early May and late June) on oil and protein content and seed yield of sesame genotypes under agro-climatic conditions of southern of Turkey in 2003 and 2004 growing seasons. Results indicated that sowing time significantly affected seed yield, 1000-seed weight, oil yield and protein yield. The highest seed yield was obtained when sesame genotypes were planted late (20 June) as second cropping. Genotype Y-A30 produced the highest seed yield (1352.2 kg ha(-1)) across the 2-year study, averaging 430 and 422 kg ha(-1) more seed yield than Vara Verde and Muganli varieties, respectively. Results from the seed analyses indicated that no difference in oil and protein contents between sowing time was observed, while genotypes displayed significant variation amongst them for oil and protein contents. Furthermore, oil and protein yields appeared to change with sowing time and in general, the earlier sowing time decreased oil and protein yield as a result of higher pod yield.Öğe EFFECT OF SOWING TIME ON PEANUT (Arachis hypogaea L.) CULTIVARS: I. YIELD, YIELD COMPONENTS, OIL AND PROTEIN CONTENT(Univ Agricultural Sciences & Veterinary Medicine Bucharest, 2016) Sogut, Tahsin; Ozturk, Ferhat; Kizil, SuleymanThe objectives of this research were to investigate the effects of sowing time and cultivar on pod yield, yield components, oil and protein content of peanut crops under irrigated condition in south-eastern of Turkey. Three peanut cultivars, Halis Bey, Osmaniye-2005 and Sultan developed by Cukurova University were grown at the experimental area of Agricultural Faculty, Dicle University, Diyarbakir, Turkey in 2010 and 2012 with two sowing times ( 15 April as early sowing and 25 June as late sowing). Treatments were arranged in split plot design replicated three times with sowing time in the main plots and cultivars in the subplots. Sowing time affected pod yield, pod number plant(-1) and oil content in both years. Early sowings resulted in higher pod yields, pod number plant(-1) and oil content compared to late sowing for all cultivars. The results also showed that cultivars were different for pod yield in both years. Sultan produced the highest pod yields under both sowing times.Öğe Effect of sowing time on peanut (Arachis hypogaea L.) cultivars: II. Fatty acid composition(Elsevier Science Bv, 2016) Sogut, Tahsin; Ozturk, Ferhat; Kizil, SuleymanThe aim of this study was to determine the effects of sowing time on fatty acid composition of three Virginia-type peanut cultivars developed at Cukurova University. The experiment was conducted at the experimental area of Agricultural Faculty, Dicle University, Diyarbakir, Turkey in 2010 growing season. The treatment was replicated three times in split-plot based on randomized complete block design with two sowing times (15 April as early sowing and 25 June as late sowing) in the main plots and three cultivars (Halis Bey, Osmaniye-2005 and Sultan) in the sub-plots. The results showed that palmitic (16:0), stearic (18:1), oleic (18:1) and gamma-linolenic acid (C18:3n-6) contents decreased, whereas, linoleic (18:2), arachidic (20:0) and eicosadienoic acid (20:2) increased with delay in sowing time. With regard to cultivars, Osmaniye-2005 was high in total unsaturated fatty acid/saturated fatty acid ratio for both sowing times. The results show that sowing time has a marked effect on the fatty acid composition of these peanut cultivars. (C) 2016 The Authors. Published by Elsevier B.V.Öğe Effects of harvesting time on some yield and quality traits of different maturing potato cultivars(Academic Journals, 2011) Sogut, Tahsin; Ozturk, FerhatThe effect of harvesting time was investigated on yield and quality traits for spring season production in different maturing potato (Solanum tuberosum L.) cultivars under agro-climatic conditions of southern of Turkey in 2006 and 2007. The experimental layout was a randomized split plot with three replications, including six potato cultivars as main plots and four harvesting times as subplots. The cultivars tested were adora (early), carrera (early), felsina (mid-early), marfona (mid-early), mondial (mid-late) and vangogh (mid-late). Samples of tubers were harvested at 75, 90, 105 and 120 days after planting (DAP) in spring crop. Early cultivars carrera and felsina gave more than 2 t ha(-1) tuber yield at 120 DAP. However, vangogh and mondial (mid-late cultivars) proved to be superior cultivars in relation to dry matter, specific gravity or starch content at 105 DAP.Öğe Essential Oil Composition of Thymus x citriodorus (Pers.) Schreb. at Different Harvest Stages(Univ Agr Sci & Veterinary Med Cluj-Napoca, 2017) Toncer, Ozlem; Karaman, Sengul; Diraz, Emel; Sogut, Tahsin; Kizil, SuleymanThymus is represented by 39 species (60 taxa) in Turkey and the rate of its endemism is 45% in Turkey. The herb is widely used for several purposes. Its essential oil compositions and biologically active substances are affected by the phenological stages. Therefore, the aim of this study is to evaluate the variations in the essential oil composition of Thymus x citriodorus (Pers.) Schreb. growing in Southeastern Anatolia Region of Turkey at different phenological stages (pre-flowering, full flowering, post flowering). The oils were obtained by hydrodistillation of air-dried samples. The yields of oils (w/w %) at different phenological stages was respectively 2.0% at pre-flowering state, 1.9% at flowering stage, and 1.3% at post-flowering stage. T. x citriodorus was determined mainly by using GC/MS. A total of 21 compounds, representing 93.9% in the pre-flowering stage, 98.8% in the flowering stage and 98.91% in post-flowering of the total oil, were identified. Monoterpene hydrocarbons (terpinolene) and oxygenated monoterpenes (alpha-terpineol) were observed to have the highest percentage in T. x citriodorus oil. The major compounds of the oil were terpinolene, alpha-terpineol, linalool, bornyl acetate and borneol. The highest percentage of terpinolene was determined to be 71% in flowering stages.Öğe Genotype x environment interaction and stability analysis of sweetpotato (Ipomoea batatas) genotypes(Taylor & Francis Ltd, 2007) Caliskan, Mehmet Emin; Erturk, Elif; Sogut, Tahsin; Boydak, Erkan; Arioglu, HalisNine introductions of sweetpotato (Ipomoea batatas) of diverse origin and two local genotypes were evaluated for storage root yield and average storage root weight in four locations of Turkey (Diyarbakir and Sanliurfa representing semi-arid environment and Adana and Hatay representing Mediterranean environment) in 2000 and 2001. The genotype x environment (GE) interaction was evaluated for two yield components (mean storage root weight and storage root yield) using the joint regression analysis and the Additive Main Effects and Multiplicative Interaction (AMMI) analysis. Stability of the genotypes over environments was estimated by using different stability parameters. GE interaction was found to be significant for both yield components, and genotype main effect contributed more than environment and GE interaction to total variability. Total storage root yield varied from 6.72 to 112.60 t ha(-1), depending on genotypes and environments. The introduced genotypes produced a higher yield than local genotypes. Our study revealed that sweetpotato has a great adaptability and yield potential in irrigated Mediterranean-type and semi-arid environments, whereas non-traditional production areas such as Adana, Diyarbakir, and Sanliurfa may be more suitable for sweetpotato production than Hatay, the traditional production area, because of the potential for higher yield. The AMMI model appeared to be a better option for evaluating both GE interaction and the stability of sweetpotato genotypes in multilocational trials. The stability parameters tested in this study could not identify high yielding and stable genotypes.Öğe MINERAL CONTENTS AND FATTY ACID COMPOSITIONS OF WILD AND CULTIVATED ROSE HIP (ROSA CANINA L.)(Parlar Scientific Publications (P S P), 2018) Kizil, Suleyman; Toncer, Ozlem; Sogut, TahsinWild Rose hip (Rosa canina L.) clone samples were collected from Dicle, district of Diyarbakir, and conserved by planting since 2002 in the Department of Field Crops, Agriculture Faculty, Dicle University, Diyarbakir, Turkey. Morphological characteristics of fruits together with mineral contents, oil yield, protein contents, ash and fatty acid contents of wild and cultivated forms of the plant were determined. Thousand seed weight were determined as 27.5 g for wild and 22.5 g for cultured rose hips. Ca concentrations were found higher in fruits compared to seeds both in wild and cultivated forms. Whereas, Fe was lower in seeds than fruits. Zn and Na concentrations were 26.7 mg kg(-1) and 129.1 mg kg(-1) in wild seeds and 39.4 mg kg(-1) and 129.4 mg kg(-1) in cultivated seeds. The fruits had Zn, Na concentrations as 16.5 mg kg(-1) and 140.9 mg kg(-1) for wild and 33.8 mg kg(-1) and 148.7 mg kg(-1) for cultivated forms, respectively. Major fatty acids of rose hip fruit and seed oil of wild and cultivated forms were oleic, linoleic, palmitic, stearic and linolenic, respectively. The fruits had main fatty acid component as linoleic acid, while in the seeds it was determined as oleic acid.Öğe PERFORMANCE OF GLYCINE MAX (L.) MERR. GENOTYPES UNDER MAIN AND SECOND CROPPING SYSTEMS: II. FATTY ACID COMPOSITION(Bangladesh Botanical Soc, 2018) Sogut, Tahsin; Ozturk, FerhatThe impact of planting date on fatty acid composition of soybean genotypes planted at main and second cropping systems was determined. The experiment was conducted in two planting dates in the main plots with four genotypes, namely HA 16-21 (MG IV), HA 36-37 (MG IV), Nova (MG III) and SA-88 (MG III)] in the sub-plots. The results showed that stearic (18 : 0), oleic (18 : 1), alpha (C18 : 3n-3) and gammalinolenic acid (C18 : 3n-6), eicosadienoic acid (20 : 2) and lignoceric (24 : 0) contents decreased, whereas, linoleic (18 : 2) and arachidic (20 : 0) increased with delay in planting date. Total unsaturated fatty acid content was higher in soybean genotypes planted late. With regard to genotypes, HA 36-37 (MG IV) was high in total unsaturated fatty acid content for both planting dates.Öğe PERFORMANCE OF SOYBEAN (GLYCINE MAX (L.) MERRILL.) GENOTYPES UNDER MAIN AND SECOND CROPPING SYSTEMS: I. GROWTH, YIELD AND YIELD COMPONENTS(Bangladesh Botanical Soc, 2017) Sogut, Tahsin; Ozturk, FerhatTo determine the effects of planting date on growth, yield and yield components of soybean genotypes an experiment was conducted. The results showed that plant height, seed yield, pod number and protein content were affected significantly by planting date. Seed yield was 22.6% higher for optimal compared to late planting. Seed mass, plant height, oil and protein content were found significantly different among genotypes. Seed yield of genotypes ranged from 2443.93 to 2542.75 kg/ha, but the differences among genotypes were not statistically significant.Öğe Rhizobium inoculation improves yield and nitrogen accumulation in soybean (Glycine max) cultivars better than fertiliser(Rsnz Publishing, 2006) Sogut, TahsinThis study was conducted to assess the effect of Rhizobium inoculation and nitrogen (N) fertiliser on N accumulation and yield in soybean (Glycine may). Six soybean cultivars belonging to maturity group (MG) II ('Corsoy 79', 'Dwight'), III ('Williams 79', 'Maverick'), and IV ('Cf 492', 'Pyramide') were grown following wheat in a double crop system in a clay soil, free of Bradyrhizobium japonicum, in 2002 and 2003. A split plot design with inoculation or no inoculation (N fertiliser application) as main plots and cultivars as subplot treatments was used, with three replications in both years. The results of these experiments indicated that inoculation increased N content and dry matter in seed and vegetative parts (stem and leaves), N harvest index, and seed yield. The interaction between inoculation and soybean cultivars (maturity group) showed that inoculation was more effective on late maturity cultivars for seed yield.Öğe TILLAGE EFFECTS ON SUNFLOWER (HELIANTHUS ANNUUS, L.) EMERGENCE, YIELD, QUALITY, AND FUEL CONSUMPTION IN DOUBLE CROPPING SYSTEM(Univ Zagreb, Fac Agriculture, 2008) Sessiz, Abdullah; Sogut, Tahsin; Alp, Aydin; Esgici, ResatThe relation between crop growing and soil tillage treatment are play important role in agricultural production. Soils under conventional tillage (CT) generally have lower bulk density and associated higher total porosity within the plough layer than under no tillage (NT). No-till farming can reduce soil erosion, conserve soil moisture and minimize labor and fuel consumption. The aim of this study were to investigate the effects of conventional, reduced and notillage methods on soil physical properties, sunflower yield and yield components, protein and oil content and fuel consumption in Southeastern of Turkey. Six tillage methods for the second crop sunflower were tested and compared each other within after lentil harvesting at 2003 and 2004 years in a clay loam soil. According to results, the first year, the bulk density had decreased from 1.29 to 1.09 g cm(-3), the second year the delta b had decreased from 1.41 to 1.23 g cm-3. Differences between years and tillage methods in terms of yield were found significant (p<0.05). However, no differences were found between the NT and CT. There were also no significance differences in content of protein, oil and ash among six tillage methods. The highest fuel consumption was measured in conventional method (CT) whereas the lowest value was found in direct seeding method as 33.48 L ha(-1) and 6.6 L ha(-1,) respectively.Öğe Yield and quality of soybean (Glycine max L.) sown as double crop under conservation and conventional tillage system in Turkey(Gaurav Soc Agricultural Research Information Centre-Aric, 2009) Sessiz, Abdullah; Sogut, Tahsin; Temiz, M. Gultekin; Gursoy, SongulSoil tillage is considered as the factor contributing to the total energy inputs in agricultural system. No-tillage (NT) is becoming increasingly attractive to farmers because it clearly reduces production costs in comparison to conventional tillage (CT). For this reason, six different soil tillage treatments in soybean production were tested within period 2003 and 2004. The effects of different tillage treatments as conventional tillage, reduced tillage (RT) and no-tillage on yield of soybean (Glycine max L.) and plant properties in south-eastern part of Turkey were studied. The soil was a clay loam with pH of 7.7 and organic matter content of 2.0%. The experiments were performed in randomized complete block design with six treatments and each treatment consisted of three replications. According to results, seedling emergence rates were not found significant between both the years and treatments (P>0.05). Results showed that the tillage treatments did not affect plant height, number of branches and first pod height for both the years. It was found that yield was significantly (P<0.001) different between years (F-year=41.288, df=1, 36; P=0.001). The yield in the second year was found to be higher than that of the first year. The highest yield was found in CT method as 3283 kg/ha and the lowest yield was found in NT method as 2520 kg/ha in year 2004. Protein, oil and ash content of soybean were not affected statistically (P>0.05) by tillage method.
