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 EVALUATION OF THIRTEEN DURUM WHEAT (TRITICUM DURUM DESF.) GENOTYPES SUITABLE FOR MULTIPLE ENVIRONMENTS USING GGE BIPLOT ANALYSIS(Parlar Scientific Publications (P S P), 2019) Kizilgeci, Ferhat; Albayrak, Onder; Yildirim, MehmetThe present study was undertaken to identify the best durum wheat genotypes suitable for the South-Eastern Anatolia Region of Turkey with desirable grain yield and quality. In the context, thirteen spring durum wheat genotypes were evaluated in four environmental condition of the target region in consecutive two growing seasons in the year 2013-14 and 2014-15. The stability and superiority of genotypes, and favorable testing environments were described by using ANOVA and GGE biplot analysis (genotype, genotype x environment). Genotype, environment and GEI (genotype x environment interaction) was found to be highly significant for multiple traits. The total variation of PCI (principles component) and PC2 was calculated 90% for ETI (environment trait interaction), 57.35 for GTI (genotype trait interaction), and 87.5% for GE interaction. The results of total variation of ETI was found higher than GTI and GEI. On the other hand, the biplot analysis showed that four megaenvironments occurred among ETI and three environments (E1, E2 and E3) correlated with different traits, while environments E4 did not correlated with any traits. The environment El was found the best for Grain yield, test weight, thousand kernel weight and starch content, E2 for L*, b*, SPAD, and E3 for zeleny sedimentation, protein content and wet gluten content. In the biplot analysis, the environments divided three sector based on traits. Among the genotypes, the genotype G8 was performed the best in all tested environments, while G9 was found the best based on all traits. The results of the study showed that GGE biplot analysis can be used as a good tool to identity of the most suitable environment in terms of all the characteristics as well as to identify the best genotypes for future breeding program.Öğe Evaluation of yield and yield components of some Turkish maize landraces grown in south eastern Anatolia, Turkey by biplot analysis(Life Sciences Soc Pakistan, 2019) Kizilgeci, Ferhat; Albayrak, Onder; Yildirim, Mehmet; Akinci, Cuma; Bicer, Behiye TubaMaize has comparatively high genetic diversity. Thus, we evaluated yield and yield traits on 92 maize landraces collected from Black Sea and Marmara Regions of Turkey and investigated three maize hybrids for yield and some morphological traits under Diyarbakir conditions in 2016 growing season. Mean value of plant height varied between 131-270 cm among maize landraces, 62.33-177cm for first ear height, 13.07-24.70 mm for stalk thickness, 9.04-22 cm for ear length, 10.70-44.16 mm for ear diameter, 7.33-16.80 for row number of ear(-1), 10-44.60 for the number of kernels in row(-1), 16.43-27.46 mm for rachis diameter and 1387-18226.7 kg ha(-1) for grain yield. According to our finding of the hybrid and the local maize genotypes, the grain yield, the number of grains in the cob and the weight of the cob, plant height, and number of rows were collected in the single group in the biplot chart. DZM-194-2 and DZM-11 local maize genotypes were found more stable for all investigated traits. DZM-7, DZM-194-2, DZM-11 and DZM-222-4 genotypes shown superiority to other genotypes in terms of grain yield.Öğe EVALUATION OF YIELD TRAITS, QUALITY PARAMETERS AND SEED YIELD STABILITY FOR LENTIL GENOTYPES UNDER DIFFERENT LOCATIONS IN TURKEY(Parlar Scientific Publications (P S P), 2019) Kizilgeci, Ferhat; Bicer, Behiye Tuba; Yildirim, Mehmet; Akinci, Cuma; Albayrak, Onder; Bayman, SerkanLentil is conventionally grown as a rain fed crop, mostly in the Middle East; it's a rich source of protein for human feeding. Yield, seed quality, adaptability and chalky spot syndrome of fifteen lentil genotypes and five lentil cultivars were evaluated in the South-Eastern Anatolia of Turkey. Yield and yield trails as well as seed quality such as protein content, seed rate with chalky spotted and germination rate for of all genotypes were varied significantly. Seed yield were varied from 1337 to 2142 kg/ha among the genotypes. While cultivar 'Sakar' produced the maximum yield and cultivar 'BM 848' produced the minimum seed yield. It was also revealed that genotypes 'ILL10975', 'FLIP2010-94L' and cultivar 'Sakar' was found the most sensitive to cold. Lentil crops with chalky spotted were detected in Adiyaman location and its rate ranged from 42% to 13%. Genotype x environment interaction was significant for seed yield and different stability parameters were computed for genotype adaptability. Ecovalance (W(2)i) and stability variance (sigma(2)i) were low value in genotypes ILL 3375 and Kafkas, but Firat 87 had high values.Öğe Exploring genetic diversity and Population structure of five Aegilops species with inter-primer binding site (iPBS) markers(Springer, 2022) Kizilgeci, Ferhat; Bayhan, Bora; Turkoglu, Aras; Haliloglu, Kamil; Yildirim, MehmetBackground Turkey is not only a center of origin for wheat, but also contains wild forms of various cereals. Turkey, located in the Fertile Crescent, has conserved its genetic richness to the present day. The aim of the study was to investigate the genetic diversity of 70 wild wheat species, to evaluate the structure of diversity in germplasm and to generate useful data for further breeding programs. Methods and results Genetic diversity and population structure of 70 wild wheat species (Ae. cylindrica, Ae. geniculata, Ae. triuncialis, T. dicocoides, Ae. columnaris) collected from Eastern and Southeastern Anatolia regions of Turkey were investigated in this study with the use of inter-primer binding site (iPBS) markers. Of 35 iPBS primers used, 11 yielded a total of 61 alleles. Number of alleles per marker varied between 2 (iPBS-2085) and 9 (iPBS-2394) with an average value of 5.55. Polymorphic information content (PIC) values varied between 0.22 and 0.47, with an average value of 0.35. Average number of effective alleles (Ne) was identified as 1.9488, Nei's genetic diversity (H) as 0,4861 and Shannon's information index (I) as 0.6791. Cluster analysis through unweighted pair-group mean average (UPGMA) method revealed that 70 wild wheats were divided into three main clusters. Genetic similarity between the genotypes, calculated with the use of NTSYS-pc software, varied between 19% (YB2 and YB70) and 98% (YB66 and YB67). Principal coordinate analysis (PCoA) revealed that three principal coordinates explained 62.33% of total variation. Moreover, population structure analysis showed that all genotypes formed three sub-populations. Expected heterozygosity values varied between 0.2666 (the first sub-population) and 0.2330 (third sub-population), with an average value of 0.2500. Average population differentiation measurement (Fst) was identified as 0.3716 for the first sub-population, 0.3930 for the second subpopulation and 0.4804 for the third sub-population. Conclusions Based on present findings population structure of 70 wild wheat genotypes collected from Eastern and Southeastern Anatolia regions of Turkey were successfully characterized with the use of iPBS markers. Present findings suggested that iPBS-retrotransposon markers could reliably be used to elucidate genetic diversity of Aegilops genotypes.Öğe Nitrogen Rate and Timing Implementation on Durum Wheat in a Bed Planting System(Univ Kebangsaan Malaysia, 2016) Yildirim, Mehmet; Yakut, Zeki; Akinci, Cuma; Kurt, Firat; Kizilgeci, FerhatThe effects of nitrogen (N) fertilization at different growth stages were investigated on durum wheat (Triticum durum L.) grain yield and yield components (with irrigated bed planting) in Diyarbakir, Turkey. N was applied at a rate of 140 kg ha(-1) and distributed to one, two and three applications at various combinations with five different growth stages (i.e. sowing, seedling growth, early tillering, stem elongation and booting). This study included 13 treatments, including the control (zero nitrogen). The N application timings (NAT) of the 50% sowing + 50% early tillering and 66% sowing + 33% early tillering treatments were most suitable for durum wheat. The results showed that NAT had significant effect on flowering time, SPAD readings of the early milky ripe stage, plant density, thousand kernel weights, grain filling duration, grain filling rate, grain N content, grain yield, harvest index and grain N yield. In summary, the highest values of parameters studied were obtained from the 50% sowing + 50% first tillering and 66% sowing + 33% early tillering treatments. N fertilization application rate and time of durum wheat genotypes should consist of applying 50-60% of the total N fertilizer at sowing and 40-50% at the early tillering stage under irrigated conditions and with bed planting.Öğe Response of Durum Wheat Seedlings to Salinity(Univ Agr Sci & Veterinary Med Cluj-Napoca, 2015) Yildirim, Mehmet; Kizilgeci, Ferhat; Akinci, Cuma; Albayrak, OnderSalinity is an important source of abiotic stress, limiting crop performance in most arid and semi-arid areas of the world. This research was conducted to determine the effects of salinity on physiological parameters of durum wheat (Triticum durum Desf) genotypes. The research was conducted in the tissue culture laboratory at the Agriculture Faculty of Dicle University. The study consisted of one durum wheat commercial cultivar, five local cultivars and four advanced genotypes. There were three replications in a split-plot experimental design. Genotypes were germinated in four NaCl concentrations (0, 50, 100, 150 mM) in plastic boxes. There were statistically assured significant differences among the genotypes for all salt concentrations and all observed parameters (coleoptile length, seedling length, root length, seedling fresh weight, root fresh weight, seedling dry weight, root dry weight, germination rare and seedling vigor). There was significant decrease in all examined parameters depending on the increase of salt concentration. The 'Sorgul' genotype was most tolerant to salinity, in terms of root length and root dry weight, whereas 'Altintoprak 98' was most tolerant as measured by the impact of salinity on coleoptile length, seedling fresh weight, germination rate and seedling vigour. The 'Beyaziye genotype was the most sensitive to salinity-induced stress. The results from this study demonstrated differences among durum wheat genotypes for seedling parameters measured in the presence of salinity stress.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 STABILITY EVALUATION OF BREAD WHEAT GENOTYPES UNDER VARYING ENVIRONMENTS BY AMMI MODEL(Parlar Scientific Publications (P S P), 2019) Kizilgeci, Ferhat; Albayrak, Onder; Yildirim, Mehmet; Akinci, CumaStable and high yield varieties identification under various conditions prior to release as a variety is the main steps for breeding program. In order to exploit narrow and broad adaptability of genotypes and assess their effects, environment and GE interaction, 12 spring bread wheat genotypes were grown at four various experimental locations during 2013-14 and 2014-15 growing seasons. The stability and superiority of genotypes were identified by the AMMI (additive main effect and multiplicative interaction) and GGE (genotype, genotype x environment) biplot analysis. The AMMI analysis showed that the variance of genotype, environment and GE interaction were significant and the major treatment sum of squares were significantly affected by environments (85.47%), genotypes (8.51%) and GE interaction (6.07%). On the other hand, the first principal component axes (PCA 1) distributed to the complete interaction as 62.56%, and the second PCA 2 axes 37.44%. The GGE bi-plot analysis indicated that the total variation PC (principle component) was 83.09%, and PC1 was accounted as 63.69%, PC2 only 19.40%. The AMMI analysis showed that C11 was quite stable as well as the highest yielder among test genotypes, while C7 and C8 were unstable and low yielding across environments. The GGE biplot indicated that it was detected in two mega-environments, and the first mega-environment covered three environment (E1, E2 and E3), and the second mega-environment covered only E4. The genotypes C11 and C12 remained superior under ME I, while genotypes C1, C3 and C5 were for ME II. Among the genotypes, the genotype C1 may be recommended to be developed and released as an approved cultivar for being comparatively more stable and the highest yielder. Therefore the AMMI and GGE biplot models have an opportunity to determine the best genotypes under multiple environments considering on adaptability and stability concentrating on overall performance for screening superior genotypes.
