Öğe CONJUNCTED FERTILIZATION REGIMES BOOST SEED YIELD AND CHEMICAL COMPOSITION OF SUNFLOWER (Helianthus annuus L.)(Parlar Scientific Publications (P S P), 2022) Elicin, Ahmet Konuralp; Ozturk, Ferhat; Koca, Yakup Kenan; Kizilgeci, Ferhat; Asan, Nihan Tazebay; Iqbal, Muhammad AamirIn the frame of sustainable farming systems to decrease chemical fertilizers use and protect the environment , organic fertilization regimes hold potential as an alternative strategy to supply essential nutrients to crops. A field trial was conducted to sort out the most superior fertilization regime for boosting sunflower production and quality under semi-arid conditions. Treatments included chemical fertilizer (Cf) (80 kg N ha(-1) and 80 kg P205 ha(-1)), manure from sheep barn manure (MSB) (5161 kg ha(-1)), manure from cattle barn (MCB) (4878 kg ha(-1)), liquid manure from cattle barn (LMCB) (27580 kg ha(-1)) and vermicompost (VCm) (4000 kg ha(-1)), while a control treatment was kept for comparison purpose. The randomized complete block design (RCBD) with regular arrangement was implied to execute the experiment having three replications. The results exhibited that MSB outperformed rest of fertilization regimes for plant height and leaf number. In contrast, the maximum 1000 seed weight and seed yield were recorded by LMCB. The MCB remained unmatched for protein content, while no significant effect of fertilization regimes was recorded for oil content. Regarding chemical composition, control exhibited the maximum palmitic and stearic acids, while MSB gave the highest arachidic acidÖğe 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.

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 SOME MECHANICAL PROPERTIES OF SOYBEAN (Glycine max) STEMS AND SEEDS(Univ Agricultural Sciences & Veterinary Medicine Bucharest, 2017) Ozturk, Ferhat; Pekitkan, F. Goksel; Esgici, Resat; Elicin, A. KonuralpHarvesting is the most important operation in soybean production. To develop a new harvesting machine with any cutting system, we have to exactly know cutting properties of stems and seeds. Firstly, the design of the machine was based on cutting properties. This study was carried out to evaluate the stem cutting properties and mechanical behavior under compression load of soybean grains (Glycine max L.). This research was conducted at the Department of Agricultural Machinery and Technologies Engineering, University of Dicle, Diyarbakir, Turkey. The soybean cultivar, SA-88, used for this study. It was obtained from the local a commercial farm in Diyarbakir Province, Turkey. In this research, Cutting force (CF), cutting strength and cutting energy (CE) for stems and seeds were measured by considering cross sectional area at during the harvesting season in year 2016. Cutting properties of soybean stems and compression properties of seeds were measured by The Lloyd LRX plus materials testing machine. The highest pod cracking force was observed as 13.43 N at vertical orientation, while the least value of cracking force was determined as 4.59 N at horizontal position. According to Tukey's multiple range tests, the internodes effects were not found significant effect on seed force and energy. The average cracking force and energy were obtained as 146. 62 N and 10.05 N.cm, respectively. Cutting force values increased linearly with the increase in stem diameters.Öğe SOYBEAN (Glycine max. (L.) Merrill) VEGETATIVE GROWTH PERFORMANCE UNDER CHEMICAL AND ORGANIC MANURES NUTRIENT MANAGEMENT SYSTEM(Parlar Scientific Publications (P S P), 2021) Elicin, Ahmet Konuralp; Ozturk, Ferhat; Kizilgeci, Ferhat; Koca, Yakup Kenan; Iqbal, Muhammad Aamir; Imran, MuhammadOptimization of fertilizers sources and doses occupies pivotal position for triggering crops growth along with reducing a halt to environmental pollution caused by excessive use of mineral fertilizers. This field research was conducted to determine the effect of chemical and organic fertilizers on vital vegetative growth parameters including leaf area index and chlorophyll content of soybean (cv. Nova).Treatments included four different sources of fertilizers manures from sheep and cattle barns, liquid manure from cattle barn, chemical fertilizers and a control treatment was kept for comparison purpose. The chlorophyll contents of plants at different growing stages Beginning bloom (R1) and Beginning seed (R5) were measured using SPAD-502 and CM 1000 chlorophyll meter. The results indicated that physiological growth parameters including leaf area index and chlorophyll content of soybean differed significantly at stage R1 and R5 growth stages under varying fertilization regimes. The chemical fertilizers remained unmatched for recording the maximum physiological growth, while liquid manure from cattle barn performed superiorly by exhibiting the maximum leaf area index and chlorophyll content. It is recommended to use liquid manure from cattle barn for boosting physiological growth of soybean and these research findings also necessitate evaluation of different doses of liquid cattle manure to sort out the best performing dose for soybean production under changing climate.Öğe THE USE OF RAPESEED OIL METHYL AND ETHYL ESTERS AND OF RAPESEED OIL-DIESEL MIXTURES AS FUELS FOR DIESEL ENGINE(Parlar Scientific Publications (P S P), 2019) Elicin, A. Konuralp; Ozturk, Ferhat; Baran, Mehmet Firat; Esgici, ResatThis study was conducted over a year period incorporating one growing seasons of 2013-2014 with the aim being to investigate the effects of the free fatty acid and yield characteristics of different rapeseed genotypes planted at different sowing times in the climate of Diyarbakir, Turkey on biodiesel production, on engine performance and on emission values. The study was conducted in the trial areas of the Department of Field Crops of the Dicle University Faculty of Agriculture, in which the quality traits of the rapeseed (oil ratio and fatty acid content) were analyzed. The genotypes, 'Licord' was achieved the highest oil content (38.13%). The highest alpha-linolenic acid (1.25%), and oleic acid (65.1%) were recorded from the genotype 'Express'. The highest linoleic acid (18.16%) was achieved from Lirown genotype. Among the different varieties of rapeseed, those with the highest oil ratio and fatty acid content were selected and subjected to transesterification to obtain rapeseed oil methyl and ethyl esters. These were then tested in a small power diesel engine in accordance with the EN 14214 standard, which is considered applicable by the Energy Market Regulatory Board of Turkey for the investigation of the performance and emission characteristics of such ester fuels. The study made use of single-cylinder, direct injection, four-cycle, 5.5 kW nominal power diesel engine. The use of fatty acid esters was found to give moment and power values close to those of diesel engine fuel, although the ester fuels showed a slight increase in fuel consumption values. The transesterification of rapeseed was found to reduce viscosity and to decrease calorific value and specific weights. Emission values for CO and CO2 were found to be lower than number 2-D diesel fuel, while an increase was observed in the level of NON.
