MATURE EMBRYO CULTURE IN BARLEY (Hordeum vulgare L.) UNDER DIFFERENT CONCENT TIONS OF SODIUM AZIDE
(FRESENIUS ENVIRONMENTAL BULLETIN, 2021) Alsoudan, Ismaeil; Haliloglu, Kamil; Kosunkartay, Hasan; Kızılgeçi, Ferhat; Kutlu, Meral
The present study was performed to determine the effects of different genotypes and concentrations of sodium azide on callus formation and plant regeneration from endosperm supported mature embryo derived calli of barley. Callus formation of endosperm supported mature embryos of two barley genotype were cultured in MS medium with five different concentrations of sodium azide (NaN3) (0, 10(-4), 10(-3), 10(-2), and 10(-1) mM). Results revealed that the main effects of both genotypes, sodium azide concentrations and their interactions on callus and embriogenic callus development and regeneration were significant or highly significant, suggesting that genotypes responded differently to the different sodium azide concentrations. The application of sodium azide application decreased the callus induction rate, embryogenic callus rate, responded embryogenic callus rate and regeneration efficiency. When evaluating the concentrations based on the averages, the highest regeneration efficiency and responded embryogenic callus rate were obtained at 10(-1) mM and 10(-4) mM concentrations, respectively, compared with the control. The highest callus induction rate (81.12%) in Alcar genotype and the highest regeneration efficiency (1.99 plants) were observed in OI-gun genotype.

PROFICIENCY OF BIPLOT METHODS (AMMI AND GGE) IN THE APPRAISAL OF TRITICALE GENOTYPES IN MULTIPLE ENVIRONMENTS
(CORVINUS UNIV BUDAPEST, 2019) Kendal, Enver; Tekdal, Sertaç; Karaman, Mehmet
The AMMI (additive main effect and multiplicative interaction) and GGE (genotype, genotype x environment) biplot analyses were used to evaluate and identify stability and yield of Triticale genotypes at three different locations throughout two years (2014-15-2015-16). The AMMI analysis of variance showed significant genotype, environment and GE interaction and indicated 1.31, 98.40 and 0.28% of total variation, respectively. The GGE bi-plot analysis indicated 78.19% of the total variation (PC1 (priciple component) 50.01%, and PC2 26.08%). This study has been useful to discriminate genotypes with superior and stable yield evaluated by the AMMI analysis and yield stability index incorporating the AMMI stability value and yield capacity in a single non-parametric index. The AMMI analysis indicated that G4, G8 (candidate) and G6 were found to be quite promising genotypes. In the GGE biplot analysis genotypes were investigated in two mega-environments, and the first mega-environment covered E3, E5 and E6, and the second mega-environment covered E1, E2 and E4. The genotypes G6, G8, G9 and Gll were the wining genotypes in ME (mega-environment) I, G3, G4 and G12 and in ME II. The GGE and AMMI biplot approaches let us to describe the best genotypes, and G8 to be stable and high yielding for both ME, G6 only for ME I, G4 only for ME II and can be recommended to release as a cultivar.

(Kahramanmaraş Sütçü İmam Üniversitesi Tarım ve Doğa Dergisi, 2022) Derviş, Sibel; Türkölmez, Şahimerdan; Eren, Abdullah; Özer, Göksel
In this study, a total of 78 Talaromyces isolates were isolated from the pistachio (Pistacia vera L.) rhizosphere heavily infested with Neoscytalidium spp. The identification studies of the four representative isolates based on morphological and molecular methods showed that all isolates were T. funiculosus. The 575 bp long sequence of the internal transcribed spacer region of T. funiculosus isolate ST976, selected as a representative of the isolates, was deposited in GenBank under accession no. MW130842. The Maximum Likelihood tree clustered the ST976 isolate with reference T. funiculosus isolates derived from the GenBank nucleotide database. The phosphorus dissolution ability of ST976 isolate was determined by an experiment using six soil samples collected from agricultural lands in various locations of Şanlıurfa province. The pH of the soil samples taken varied between 7.21 and 7.88. As a result of the analysis performed with the addition of the isolate ST976 applied to soil samples with different soil structures (Clay and Clay-Loam), it was determined that the isolate ST976 dissolved 109–311% more phosphorus than the control sample. The study is one of the first studies proving the ability of T. funiculosus isolate ST976 to dissolve phosphorus without any additives to soil solution was determined.

Effects of chemical, organic and microbial fertilization on agronomical growth parameters, seed yield and chemical composition of chickpea
(POLISH SOCIETY MAGNESIUM RESEARCH, 2023) Doğan, Serap; Çığ, Fatih
Because of its valuable nutritional content, chickpea is expected to become the most important crop for the increasingly larger global population. Therefore, this research was carried out in 2018 and 2019 to investigate the effects of microbial (Bacillus-GC group, Pseudomonas tetraodonis and Brevibacillus choshinensis), organic (vermicompost and chicken manure) and chemical (DAP/2 ve DAP) fertilizer applications on yield and nutritient content of two different chickpea cultivars (Arda and Azkan). The experiment was laid out according to a randomized complete split-block design with three replications. The results expressed as the average values of two-year experiments projected that the application of chicken manure significantly improved the morphological traits of chickpea plants compared to the other treatments, while the highest phosphorus content was recorded after the application of farm manure. Additionally, the highest grain yield from both cultivars was obtained owing to the application of chicken manure. Apart from this effect, other microbial applications also played a positive role in plant growth and production, but chicken manure excelled in this respect. Thus, it has been concluded that chicken manure could be used as a suitable alternative to chemical fertilizer for chickpea culti vation in order to create a sustainable agricultural system, increase productivity and protect and improve soil properties.
NUTRIENT STATUS AND YIELD OF CHICKPEA (Cicer arietinum L.) AS INFLUENCE BY APPLICATION OF DIFFERENT HARVEST TIMING AND SULPHUR FERTILISER
(Oxidation Communications, 2015)
The objectives ofthis research were to study the effect of harvesting time and sulphur levels on the yield, protein and mineral nutritional value of chickpea seeds. Three dif ferent harvesting times (early, on-time and late) and four sulphur levels (0,20, 40 and 60 kg ha-1) were used. Yield, protein ratio and mineral nutritional value of chickpea were significantly affected by sulphur and harvest timing. The highest grain yields according to the harvest time were obtained from on-time harvest with 1527 and 1434 kg ha 1 for the first and second years, respectively. The lowest grain yields were obtained from the control plots, whereas the highest values were obtained from the plots given 60 kg ha 1 sulphur. Generally, protein, phosphorus, calcium, magnesium, copper, zinc, and manganese concentrations of the seeds in on-time harvest and 60 kg ha 1 sulphur aplication were found to be greater than in early and late harvested plants. Positive significant relationships were found between harvest time and protein (r = 0.64"), Fe (r = 0.75") and Zn (r = 0.27*). Positive significant relationships were found between sulphur doses and grain yield (r = 0.44*), protein (r = 0.26*), P (r = 0.71” ), K (r = 0.73**), Ca (r = 0.36**), Mg (r = 0.76*), Zn (r = 0.57) and S (r = 0.96*).

(2021) Eliçin, Ahmet Konuralp; Öztürk, Ferhat; Kızılgeçi, Ferhat; Koca, Yakup Kenan; Iqbal, Muhammad Aamir; Imran, Muhammad
Optimization of fertilizers sources and doses occupies pivotal position for triggering crops growth along with reducing a halt to environmental pollu tion 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 in dex and chlorophyll content of soybean (cv. Nova).Treatments included four different sources of fertilizers manures from sheep and cattle barns, liq uid manure from cattle barn, chemical fertilizers and a control treatment was kept for comparison purpose. The chlorophyll contents of plants at different grow ing 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 fertiliz ers remained unmatched for recording the maximum physiological growth, while liquid manure from cat tle barn performed superiorly by exhibiting the max imum 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.

Traditional uses of wild plants in Mardin central district and attached villages (Turkey)
(INDIAN JOURNAL OF TRADITIONAL KNOWLEDGE, 2021) Kılıç, Murat; Yıldız, Kemal; Mungan Kılıç, Fatma
This research reveals traditional uses of wild plants found in Artuklu district in Mardin Province in the Southeastern Anatolia Region of Turkey. This study, conducted between 2017 and 2019, gathered information on the medicinal and other uses of plant species traditionally used in Artuklu and the local names of these plants. Face to face surveys were conducted with 183 people in 91 neighbourhoods. The ethnobotanical uses of 125 plants belonging to 35 families, which are traditionally underutilized by the local people, have been recorded. Our results showed that the highest Relative Frequency of Citation (RFC) was recorded for the species Lathyrus pseudocicera Pamp. (0.32). 1 taxon is from Stereocaulaceae of Fungi, 2 taxa are from Pteridophyta and the others 122 taxa are from Magnoliophyta. In the region, plants mostly belonging to the families Fabaceae (21 taxa), Lamiaceae (11 taxa), Asteraceae (10 taxa) and Brassicaceae (10 taxa) were determined. The recorded ethnobotanical uses are for: food (64), medicinal (40), fodder (12), children's toys (5) and various other purposes (4). Due to the fact that Turkish, Kurdish, Arabic and Assyrian people have lived together in the Artuklu district, this ethnic diversity increased the use of wild plants and added richness. Preserving the coexistence of different cultural and religious groups in the research zone is essential for the maintenance of the rich wild plant local heritage.

ORGANIC AMENDMENTS AND NANO-MICRONUTRIENTS RESTORE SOIL PHYSICO-CHEMICAL PROPERTIES AND BOOST WHEAT YIELD UNDER SALINE ENVIRONMENT
(FRESENIUS ENVIRONMENTAL BULLETIN, 2021) Sorour, Sobhy; Amer, Megahed Mohamed; El Hag, Dalia; Hasan, Etab Ahmed; Awad, Mahrous; Kizilgeci, Ferhat; Ozturk, Ferhat; Iqbal, Muhammad Aamir; El-Sabagh, Ayman
Ensuring food security under climate change scenario requisites amending degraded soils and sustainably boost staple crops yield in a biologically viable way through effective plant nutrition management strategies. Two multi-year lysimeter experiments were conducted to investigate the impact of soil organic substances and foliar application of some nano-nutrients on soil properties and wheat yield under saline conditions. The experiment was executed in split plot with three replications. Treatments included organic amendments (molasses, compost tea, K-humate, molasses+ compost tea, molasses+K-humate, compost tea+ K-humate and molasses+K-humate+Compost tea and control) in main plots, while sub plots had nano-micronutrients (nano-selenium, nano-manganese and nano-silica) and a control treatment. The results showed that physio-chemical properties (bulk density, cation exchange capacity, electrical conductivity etc.) of the soil were significantly influenced by all organic amendments; however, co-application of molasses+K-humate+compost tea remained unmatched. The same treatment combination also remained effective in boosting nitrogen uptake and recovery along with wheat yield during both seasons. Among foliage applied nano micronutrients, silicon remained superior by recording the highest yield attributes and grain yield of wheat. Therefore, it is inferred that co-application of organic amendments and foliage applied nano-fertilization management could be developed as an effective approach to restore and conserve the soil and increase wheat productivity under saline environment of arid and semi-arid regions.

TRACING HIGHLY ADAPTED STABLE YIELDING BREAD WHEAT (TRITICUM AESTIVUM L.) GENOTYPES FOR GREATLY VARIABLE SOUTH-EASTERN TURKEY
(CORVINUS UNIV BUDAPEST, 2016) Aktas, H.
Wheat (Triticum aestivum L.) is the most widely adapted and cultivated cereal grain in the world. In 2013 cropping season, wheat was harvested on 1.3, 7.8, and 214 million ha in south-eastern Turkey, Turkey and World, respectively. Breeding programs in the Turkey have achieved tremendous gains in grain yield over past two decades. However, yield fluctuated over the years due to change in environmental conditions and genotype by environment interactions. Therefore, this study was conducted with overall objectives to identify high yielding and stable candidate genotypes for release in southeastern Turkey. A total of 25 genotypes with 20 advanced experimental lines and five check cultivars were planted at 10 locations in south-eastern Turkey in 2010-11 cropping season. Grain yield stability was determined using Eberhart and Russel, AMMI and GGE-biplot methods. Based on these results G1, G12, G13 and G19 were identified as the potential candidate genotypes for release. GGE-biplot classified south-eastern Turkey into two mega-environments. AMMI and GGE biplot explained 86.49% and 86.43% of the total variation for grain yield, respectively. These result suggested that all three methods were equally efficient in determining the stability of the genotype. However, the GGE biplot methodology is more preferred than AMMI and Eberhart and Russel because it facilitates clearly visualize which-won-where pattern and the discriminating ability of environments.

Factors influencing adaptation of innovations in small ruminant production in the TRC3 Region in Turkey
(Emirates Journal of Food and Agriculture, 2021) Acıbuca, Veysi; Bostan Budak, Dilan
This study investigated the socio-economic factors affecting the adoption of innovation in small ruminant production in TRC3 region in Turkey. Stratified random sampling technique was used to select 366 small ruminant farmers from the region. Semi-structured questionnaire was used to collect main data for the study. Data collected were analyzed using descritive statistics, t-tests and multiple linear regression analysis. Results of the study showed that the farmers had a mean age of 45,8 years and 97,0% were male. Traditional production was dominant among the small ruminant producers and as the number of animal increases the income increases (p< 0,01). Out of twelve independent variables, eight of them were statistically significant on multiple linear regression analysis. The F-statistics was statistically significant at 1% level on communication behavior and animal health practices; 5% level on age, breeding reasons, milking way, produced products and fold type. The coefficient of multiple determination (R2) value was estimated to be 0,470 this implies that 47,0% of total variation in the output of small ruminant production was accounted for by the independent variables that were fitted into the model. The main problems of small ruminant production were high feed prices, high deaths of lamps/goat, insufficient use of pastures because of security problems and lack of shepherd due to young people unwillingness to live in rural areas
Correction to: Leaf spot caused by Alternaria crassa on Datura stramonium in Turkey
(Australasian Plant Disease Notes, 2022) Bozoğlu, Tuğba; Alkan, Mehtap; Derviş, Sibel; Özer, Göksel
In August 2021, jimson weed (Datura stramonium) plants growing as weeds in potato fields in Bolu province, Turkey, exhibited leaf spots with dark concentric rings. Sunken and lens-shaped lesions with a light center were also frequently observed on petioles, branches, and stems. Based on morphological characteristics and phylogenetic analysis of the transcription elongation factor 1-α, RNA polymerase second largest subunit, and glyceraldehyde-3- phosphate dehydrogenase loci, the causal agent was identified as Alternaria crassa. The pathogen was successfully re-isolated from inoculated jimson weed plants in the pathogenicity assay, proving Koch’s postulates. Alternaria crassa caused necrotic lesions on potato plants, similar to those of early blight, confirming them as an alternative host of the pathogen. This is apparently the first report of leaf spot caused by A. crassa on jimson weed in Turkey.

The purpose of this study was to investigate the resistance of bread and einkorn wheat genotypes under in vitro conditionsagainst drought stress during germination. Twelve bread and ten einkorn wheat genotypes were used as plant material and sevendrought stress levels were appliedbased ona three-replicate factorial restricted randomized block design in order to investigate their effects on germination rate (GR), germinating power (GP), coleoptile length (CL), shoot length (SL), root length (RL), shoot root length ratio (SRLR), root fresh weight (RFW), root dry weight (RDW), and root fresh dry weight ratio (RFDWR) during the year 2014-2015. PEG–6000 was used toevaluate the effect of drought stress under in vitro conditions on the wheat genotypes.The values of all traits were decreasedbytheincreased effect ofPEG levels (p≤ 0.05).The results of the variance analysisshowedthat thegenotypeshadsignificant statistical differences for theexaminedtraits under drought stress(p < 0.05).According to theresults of theGGE biplot analysis, of the total variation between the genotypes and traits investigated under drought stress (75.97%), PC1and PC2 represented51.51% and 24.47%, respectively. In addition, einkorn wheat populationswerelocated inthesector of GR, GP, and SRL,which means that these populations had agreater performance for these traits under drought stress conditions.Bread wheat and einkorn genotypes behaved differently for the traits under drought stress. It is considered that the results of the field and in vivo experiments for cold and drought stresswill contribute toproducingreliable suggestions.
DROUGHT TOLERANCE INDICES OF SELECTED LANDRACES AND BREAD WHEAT (TRITICUM AESTIVUM L.) GENOTYPES DERIVED FROM SYNTHETIC WHEATS
(APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH, 2016) Aktaş , Hüsnü
The present study was performed to determine performance of selected four synthetic derived bread wheat genotypes, four bread wheat landraces and four modern wheat genotypes under rain-fed and supplemented irrigation experiments based on randomized complete block design with four replications at GAP International Agricultural Research and Training Center, Diyarbakır, Turkey in 2013-2014 and 2014-2015 growing seasons. According to results of pairwise correlation and biplot analysis, significant and positive correlation was observed between grain yield in stress condition (Ys) and stress tolerant index (STI), geometric mean productivity (GMP), mean productivity (MP), harmonic productivity (HM), yield stability index (YSI), yield index (YI), drought resistance index (DI) and stress non-stress production index (SNPI) indicating these indices can be used as parameters for evaluating drought tolerant genotypes. Negative correlation between grain yield in stress (Ys) with SSI and no correlation with TOL indicated that these indices should be used in severe drought conditions for screening genotypes. Number seed in spike (NSS), plant height (PH) and thousand kernel weight (TKW) correlated with grain yield in stress conditions (Ys) according to biplot analysis, also genotypes with lower reduction relating to these traits had higher yield in stress conditions. According to results SEN-DER genotypes G7, G10, landrace group genotype G11 (Sorık) were determined as the most tolerant genotypes to be used to improve drought tolerant varieties, while modern wheat genotypes G4 (Ceyhan-99) and G2 (Tekin) were high productive in irrigation conditions and low productive in rain-fed conditions.

SELECTION THE BEST BARLEY GENOTYPES TO MULTI AND SPECIAL ENVIRONMENTS BY AMMI AND GGE BIPLOT MODELS
(Fresenius Environmental Bulletin, 2018) Oral, Erol; Kendal, Enver; Doğan, Yusuf
The stability of genotypes is significant to selection and improves new varieties. The effect of genotype x environment interaction is revealed by different analysis methods. Nowadays, majority of researchers have been used the AMMI (Additive main effects and multiplicative interaction) and GGE biplot analysis in multi-environment trials. Therefore, ten barley advanced line and cultivars were used in the study. The experiments were performed according to a complete randomized block design with four replications at six environments in 2010-2011 seasons. The stability and superiority of genotypes for yield was determined using AMMI and GGE biplot analysis. Factors (G, GE, and GEI) were found to be highly significant (P 0.01) for grain yield. AMMI analysis indicated that the major contributions to treatment sum of squares were environments (89.77), genotypes (7.25) and GE (2.96), respectively, suggesting that grain yield of genotypes were effected environmental conditions. The GGE biplot indicated that PCA 1 axes (Principal component) was significant as P0.01 and sup- plied to 75.33 of complete GxE interaction. The AMMI indicated that G6 was stable, while G10 and G9 were high yielding for grain yield in multienvironment. Moreover, E1 and E4 were high yielding, while E2, E5 and E6 low yielding as forecast. On the other hand, GGE biplot indicated that three group were occurred among environments, first group (E1, E2 and E6), second group (E3, and E4), third group (only E5). Moreover: the study showed that G6 and G9 were the best genotypes for first group, G10 for second and G1 for third of environments, while other genotypes didn’t show any relation with environments. The results of AMMI and GGE biplot models indicated that G6 was stable in all environments. Therefore this genotype can be recommend for release to all environ- ments, while G9 for first group and G10 for second group.

(Aloki Applied Ecological Research and Forensic Inst Ltd, 2019) Dogan, Y.; Togay, N.; Togay, Y.
The aim of this study was to determine the most suitable irrigation schedules and sources of manure for maize under Mardin ecological conditions. For this purpose, four sources of fertilizer and three irrigation schedules were applied in hybrid maize cultivar to find out their effects on the yield and yield factors in the years of 2014 and 2015. The study used a randomized complete block with split block design with 3 replications. In the study, significant differences were determined on traits at the level of 1% and 5%. The plant height, first cob height, cob length, number of seeds per cob, cob yield, 1000 seed weight, seed yield per unit, hectoliter, protein and oil ratio in seed, Mg, K, Fe, Ni, Cu, Zn, Mn, Na, Ca content of seeds were significantly influenced by irrigation schedules and sources of fertilizer for two years. The highest values were obtained from chicken manure with 9646 kg ha(-1) in the first year and 11019 kg ha(-1 )in the second year, whereas the lowest values were obtained from control with 6363 and 6662 kg ha(-1) for the first year and the second, respectively. But the difference between 180-80 kg N-P(2)0(5) ha(-1) and chicken manure was not statistically significant in the second year. According to the irrigation schedules, the grain yield ranged between 6386-10678 kg/ha in the first year and 7575-12133 kg ha(-1) in the second year. The lowest grain yield per area was from the four-irrigation application, whereas the highest values were obtained from the six-irrigation application. The results of the study showed that grain yield and nutrient level of corn seeds increased, depending on irrigation time and number.
