Activity of Metalaxyl-M plus mancozeb, Fosetyl-Al, and Phosphorous Acid against Phytophthora Crown and Root Rot of Apricot and Cherry Caused by Phytophthora palmivora
(CZECH ACADEMY AGRICULTURAL SCIENCES, 2017) Türkölmez, Şahimerdan; Derviş, Sibel
Crown and root rot, caused by the Oomycete pathogen Phytophthora palmivora, has become a destructive disease of apricot and cherry in eastern Turkey. There are no currently registered fungicides labeled for its control. In greenhouse experiments conducted in 2012 and 2013, 1-year-old potted apricot rootstock Zerdali and cherry rootstock Mahaleb plants were treated either with foliar spray of fosetyl-Al (140, 160, and 180 g a.i./100 l) or phosphorous acid (187.5, 200, and 215 g a.i./100 l) or soil drench of 100 ml of metalaxyl-M (= mefenoxam)+mancozeb (12+192, 16+256, and 20+320 g a.i./100 l) one day after wound inoculation of crowns and roots. In both years, phosphorous acid at 200 and 215 g a.i./100 l, fosetyl-Al at 160 and 180 g a.i./100 l, and metalaxyl-M+mancozeb at 20+320 g a.i./100 l significantly reduced the root rot severity on Zerdali by 70.68-80.00% and crown rot severity on both Zerdali and Mahaleb, by 68.32-91.96 and 74.21-82.60%, respectively, compared with phosphorous acid at 187.5 g a.i./100 l, fosetyl-Al at 140 g a.i./100 l, metalaxyl-M+mancozeb at 12+192 and 16+256 g a.i./100 l and control. Moreover, fosetyl-Al at 180 g a.i./100 l and metalaxyl-M+mancozeb at 20+320 g a.i./100 l significantly reduced the root rot severity on Mahaleb compared to fosetyl-Al at 140 and 160 g a.i./100 l, metalaxyl-M+mancozeb at 12+192 and 16+256 g a.i./100 l, phosphorous acid treatments and control in 2012, providing the best control of the disease by 88.00-90.68%. Two/three phosphorous acid foliar applications at 200 g a.i./100 l suppressed symptom development when field applications were made on a curative basis in 2014 and 2015.

Allelic variations of glutenin subunits and their association with quality traits in bread wheat genotypes
(2017) Aktaş, Hüsnü; Baloch, Faheem Shehzad
The present study was conducted to evaluate the genotype × environment interaction of the yield and quality traits for five bread wheat varieties commonly grown in the Southeastern Anatolia Region of Turkey and 20 advanced lines developed within the framework of the International Winter Wheat Improvement Project. We also determined the allelic pattern of the Glu-1 and Glu-3 loci of these genotypes and examined whether these loci had an effect on the quality traits. There was a significant variation among the genotypes and environments in terms of grain yield, protein content, sedimentation volume (SV), and the extensograph dough energy value (EDEV). The results of the study indicated that genotypic effect was more influential on SV and EDEV than environmental effect; thus, both traits could be used in breeding programs to develop elite cultivars with better quality. Twelve different high-molecularweight (HMW) glutenin alleles were identified at the Glu-A1, Glu-B1, and Glu-D1 loci, resulting in 14 allelic combinations, and 17 different alleles were observed in 19 combinations for low-molecular-weight (LMW) subunits. Furthermore, among all the genotypes, 13 + 16 and 13 + 19 alleles at Glu-B1 and 5 + 12 at Glu-D1 were observed to have the lowest frequency. Our study indicated that the combinations of HMW glutenin alleles with 2* at Glu-A1, 17 + 18 and 13 + 16 at Glu-B1, and 5 + 10 at Glu-D1, as well as the combinations of LMW alleles with subunits c and d at Glu-A3; subunits d, b, c, and g at Glu-B3; and subunits a and b at Glu-D3 had positive effects on the quality traits.

Alternaria alternata causing inner black rot of lemon (Citrus limon) fruits in Turkey: Genetic diversity and characterisation
(ScienceDirect, 2023) Güney, İnci Güler; Derviş, Sibel; Fatih Tekin, Tacettin Utku Günen, Göksel Özer
The market sales of symptomless lemons in 2020 revealed a persistent and severe internal black rot with browning of the membrane wall and juice sac. To investigate the causal agent, externally symptom-free lemons from Mediterranean locations were sampled from supermarkets, local markets, and bazaars in three southeastern Turkish provinces. Internal black rot symptoms were observed in 13.69% of the 1300 externally symptomless fruits, and Alternaria was isolated from 96.63% of those exhibiting these symptoms. Morphological analysis confirmed the identity of Alternaria alternata in 26 representative isolates collected from various markets and bazaars. To examine genetic diversity or polymorphisms, start codon targeted (SCoT) markers were used. Species identification was based on the sequences of translation elongation factor 1-alpha (TEF 1-α), RNA polymerase second largest subunit (RPB2), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH). SCoT 29 exhibited the highest amount of polymorphic amplicons, with 18 polymorphic bands scored when compared to the other six scoreable markers. The 26 representative isolates from various markets and bazaars were divided into four clades by SCoT 29. However, multilocus sequence analyses confirmed the identification of a single species, A. alternata. In terms of virulence and the impact of temperature on growth, representative isolates from four SCoT clusters were evaluated. Data suggests that SCoT markers can be used to evaluate virulence-based polymorphism in A. alternata; nonetheless, all clades showed comparable temperature responses, with 25 ◦C being the optimum. There was also no association between individual morphotypes and SCoT clade membership. Due to the lack of obvious signs on lemon fruits, producers, merchants, and consumers are unable to identify black rot, and the widespread presence of A. alternata in lemons may pose a significant risk that must be avoided at all costs.

(Scibulcom Ltd, 2015) Dogan, Y.; Doğan, Yusuf; 06.02. Department of Plant Protection / Bitki Koruma Bölümü; 06. Faculty of Agricultural Sciences and Technologies in Kızıltepe / Kızıltepe Tarım Bilimleri ve Teknolojileri Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Chickpea has significant amounts of all the essential amino acids except sulphur-containing types. It was found that chickpea is a rich source of protein and minerals. The experiments were conducted in a Randomised Complete Block Design with three replications 2013 and 2014 years in South-Eastern Turkey. A total of fifteen varieties, lines and populations were used as materials. In the study were investigated different parameters such as amino acids of protein, seed yield, protein and fat rate in seed, phosphorus, potassium, calcium, manganese, zinc, copper and iron contents and of seeds. The essential amino acid leucine (8.43 mg/100 g in 2013 and 8.59 mg/100 g in 2014) was found in highest concentration, followed by lysine (7.14 mg/100 g in 2013 and 7.27 mg/100 g in 2014) and phenylalanine (5.99 mg/100 g in 2013 and 6.07 mg/100 g in 2014) in the chickpea. Mineral composition of chickpea genotypes showed that they contribute sufficient amount of Ca, P, K, Cu, Zn and Mg in human diets to meet the recommended dietary allowance. According to the average of two years, the highest grain yield was obtained from Diyar-95 variety with 1618 kg ha(-1), the lowest grain yield was obtained from M-1 local population with 1104 kg ha(-1).

AMMI Model to Assess Durum Wheat Genotypes in Multi-Environment Trials
(JOURNAL OF AGRICULTURAL SCIENCE AND TECHNOLOGY, 2018) Tekdal, S; Kendal, E.
The goal of this research was to assess the stability and yield performance of 150 durum wheat genotypes in multi-environment trials in two locations (Diyarbakir and Kiziltepe), in 2011-2012, and 2012-2013 growing seasons. The trials were designed by Lattice Experimental Design with two replications (incomplete block design). The AMMI (Additive Main Effects and Multiplicative Interaction) and GEI (GenotypexEnvironment Interaction) analysis were used in the study to estimate GEI effects on grain yield, because of plant breeders' great interest in these models for breeding programs. AMMI evaluation indicated that genotypes made the most important contributions to treatments Sum of Squares (59.8%), environments (3.5%), and GEI (36.7%), respectively, suggesting that grain yield had been affected by environment. IPCA 1 and IPCA 2 axes (Principal Component) were significant as P< 0.01 and explained 63.8 and 36.2%, respectively. Results showed that Kiziltepe 2013 was more stable and high yielding, meanwhile Diyarbakir 2012 and Diyarbakir 2013 environments were unstable and low yielding. According to stability variance, usually the province lines were more productive and stable than some old cultivars and many landraces/genotypes. Moreover, genotype G24 was more effective in all environments. The GEI model according to AMMI analysis suggested that this genotype can be considered as a candidate, due to extensive adaptability and high performances in all environments.

(Aloki Applied Ecological Research and Forensic Inst Ltd, 2019) Tekdal, S.; Dogan, S.; Kendal, E.; Karaman, M.
The development of stable and adaptable new cultivars are based only on positive results obtained from the interaction between the genotype and the environment. Therefore, the study aimed to test the stability and general adaptability of promising barley lines in terms of grain yield and traits in multi -environments. For this purpose, twelve barley genotypes were used in the study. The trials were carried out with four replications in a random design at seven environments in years 2012-13 and 2013-14. The superior and stable genotypes were identified with GGE biplot and AMMI (Additive main effects and multiplicative interaction) models. The AMMI analysis showed that the major treatment sum of squares was affected by environments (80.6%), GE (14.0%) and genotypes (5.4%), respectively. On the other hand, the first two principal component axes (PCA 1 and PCA 2) contributed to the complete interaction with 88.1%, whereas, PCA 3 and PCA 4 axes only with 12.0%. The GGE biplot indicated that G4 is adaptable for all environments, while Altikat, G2 and G3 showed specific adaptation to El, E3 and E5, G6, G7 and G8 to E6, respectively. According to both techniques, G2, G3, G6, G7, G8 and Altikat were the best genotypes with high yield, whereas G4 was the best with high yield, and stable and general adaptation. The results of biplot indicated that G4 (ARUPO /K8755//MORA/3/CERISE/SHYRIHALEL I/4/CANELA/5/HART-BAR) was recommended for release and it was released as HEVSEL in 2017. On the other hand; G7 and G6 were protected as genetic material to use as parent in breeding programs for yield stability and quality respectively.

Canker and leaf scorch on olive (Olea europaea L.) caused by Neoscytalidium dimidiatum in Turkey
(ScienceDirect, 2022) Güney, İnci Güler; Özer, Göksel; Türkölmez, Şahimerdan; Derviş, Sibel
In a recent survey of olive groves in the Southeast Anatolia Region of Turkey, a new and serious decline of olive trees, beginning with foliar scorching and then dieback of twigs, branches, and even whole trees, was observed for the first time. In more advanced stages of the disease, necrosis and cankers were observed on the bark of the trunk, branches, and twigs. Isolations from symptomatic tissues from multiple cultivars in diverse locations yielded Neoscytalidium dimidiatum, which were identified using ITS, tef1, and tub2 loci of genomic DNA, in combination with morphological data. In vitro studies showed that conidial germination, hyphal growth, and pycnidia formation of the pathogen were positively correlated with elevated temperatures. Wild type olive “Delice”, “Edincik Su”, and “Memecik” seemed like the most resistant cultivars on which disease severity values were the lowest among 14 screened olive cultivars in two experimental orchards under natural conditions. Pathogenicity tests showed that “Gemlik” was the most susceptible cultivar showing the largest cankers and extensive scorch lesions. Isolates caused canker but not leaf scorch on O. europaea cultivars “Arbequina” “Halhalı”, “Manzanilla”, “Nizip Yağlık”, and “Saurani”. Neoscytalidium isolates are likely to have a negative impact on the health of diverse olive groves, which are primarily confined to Mediterranean-type climatic regions. These findings suggest an increased risk of infection in environments with increasing temperatures, as is common in the Southeast Anatolia Region of Turkey. The information gathered in this study will be used to examine the disease's epidemiology and establish disease control initiatives. This is also the first report of N. dimidiatum infecting O. europaea in the world.

Characterization and pathogenicity of Pythium-like species associated with root and collar rot of kiwifruit in Turkey
(In Plant Disease, 2021) Türkkan, Muharrem; Özer, Göksel; Karaca, Gürsel; Erper, İsmail; Derviş, Sibel
During the period of June to October in 2018, a widespread decline was observed on kiwifruit vines in the vineyards located in Altınordu, Fatsa, and Perşembe districts of Ordu province. The symptoms were associated with reddish-brown rots expanding from the root to the collar with sparse off-color foliage. Based on the percentage of the total infected samples across 18 vineyards, the most common oomycete species were Globisporangium intermedium (37.1%), Phytopythium vexans (34.3%), G. sylvaticum (14.3%), G. heterothallicum (11.4%), and Pythium dissotocum (2.9%). The morphological identification of isolates was confirmed based on partial DNA sequences containing the nuclear rDNA internal transcribed spacer region (rDNA ITS) and the mitochondrial cytochrome c oxidase subunit II (coxII) gene. The optimum growth temperature and the optimum pH of 5 species ranged from 22.98 to 28.25°C and 5.67 to 8.51, respectively. Pathogenicity tests on the seedlings of kiwifruit cv. Hayward revealed significant differences in virulence among isolates. Phytopythium vexans and G. sylvaticum isolates caused severe root and collar rot resulting in seedling death, while G. heterothallicum and G. intermedium isolates had relatively lower virulence. All Globisporangium spp. and P. vexans isolates significantly decreased plant growth parameters (plant height, shoot and root dry weights and root length); however, P. dissotocum caused very mild symptoms and did not affect these parameters of growth. To our knowledge, this is the first study reporting G. sylvaticum, G. heterothallicum, and G. intermedium causing root and collar rot on kiwifruit not only in Turkey but also in the world.

The characterization of phenolic compounds via LC-ESI-MS/MS, antioxidant, enzyme inhibitory activities of Salvia absconditiflora, Salvia sclarea, and Salvia palaestina: A comparative analysis
(ScienceDirect, 2022) Önder, Alev; İzgi, Mehmet Necat; Cinar, Ahsen Sevda; Zengin, Gökhan; Yılmaz, Mustafa Abdullah
Abstract Salvia L. genus, one of the medicinal and aromatic plants belonging to the Lamiaceae family, is represented by many endemic species in temperate regions worldwide. The Salvia species have plenty of usages in traditional medicine, important pharmacological effects and economic value. In this context, this study was conducted to evaluate the chemical profile and potential bioactivity of ethyl acetate extracts from 3 different Salvia species; Salvia absconditiflora (Salvia cryptantha- an endemic species), S. sclarea and S. palaestina collected from different localities in Anatolia. Total phenolic-flavonoid contents, antioxidant properties and enzyme inhibition experiments were investigated in tested Salvia species. The phenolic profiles were also determined by liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The analysis revealed the presence of phenolic compounds in ethyl acetate extracts such as cynaroside, rosmarinic acid, cosmosiin, luteolin, apigenin and acacetin. The highest level of phenolic components was detected in S. absconditiflora with 74.16 mg GAE/g. The best radical scavenging and reducing abilities were found in S. absconditiflora (DPPH: 251.39 mg TE/g; ABTS: 340.16 mg TE/g; CUPRAC: 496.20 mg TE/g; FRAP: 322.94 mg TE/g). Moreover, the inhibition of AChE, BChE, and α-amylase has also been studied. The most potent AChE inhibitory ability was recorded in S. sclarea (4.00 mg GALAE/g), followed by S. palaestina (3.38 mg GALAE/g) and S. absconditiflora (3.01 mg GALAE/g). The extracts exhibited similar amylase inhibitory effects. These results reveal that Salvia species [S. absconditiflora (S. cryptantha), S. sclarea and S. palaestina] confirming their potential can be rich sources of promising bioactive compounds as a starting point for further analysis. In addition, it is thought that this study may be the new report for the construction of helpful databases in terms of shedding light on future research and researchers with the valuable information obtained about these economically important Salvia species.

Clonostachys rosea Strain ST1140: An Endophytic Plant-Growth-Promoting Fungus, and Its Potential Use in Seedbeds with Wheat-Grain Substrate
(SpringerLink, 2023) Türkölmez, Şahimerdan; Özer, Göksel; Derviş, Sibel
In this study, Clonostachys rosea strain ST1140, a naturally occurring endophyte in healthy roots of a pistachio tree, was identifed morphologically and molecularly through DNA sequencing, and its endophytic ability and growth efect in/on three solanaceous plant species were tested. Three diferent organic substrates (bread wheat-grain, sawdust, and leonardite) were also investigated for their utility in cultivating and multiplying the strain. In-tray and pot experiments, the rates of seed germination and vegetative development of pepper, tomato, and eggplant inoculated with C. rosea at planting were compared to those of non-inoculated controls. In pot experiments, inoculating seedbeds with increasing doses of C. rosea strain ST1140 with wheat-grain substrate resulted in higher plant height values for all plant species, and the strain endophytically colonized the roots of all plant species. In-tray experiments revealed that ST1140 inoculation resulted in 2–4 days earlier and 10% higher germination rates for all plant species, as well as more vigorous and accelerated seedling growth (10–13 days earlier for seedlings at the 4–5 true leaf stage) on all inoculated plant species. Among three diferent organic substrates, wheat-grain was found to be the most efective for long-term cultivation and multiplication of the fungus, which could be of interest for its development as a commercial product. These results promised the strain ST1140’s use as a biofertilizer in seedbeds with a wheat-grain substrate.

(Fresenius Environmental Bulletin, 2021) Eliçin, Ahmet Konuralp; Öztürk, Ferhat; Kızılgeçi, Ferhat; Koca, Yakup Kenan; Iqbal, Muhammad Aamir
Environmental pollution sed by leaching and gaseous issions from chemical fertilizers necessitates evluation and optimization of organic sources of plant nutrition for soybean production under changing climate scenario. A field study was executed to test different fertilization regimes including chemical fertilizers (CF) (80 kg N and 80 kg P2O5 ha(-1)), sheep barn manure (SBM) (5161 kg ha(-1)). cattle barn manure (CBM) (4878 kg ha(-1)), liquid cattle barn manure (LCBM) (27580 kg ha(-1)) and vermicompost (VC) (4000 kg ha(-1)). The yield attributes, grain yield and fatty acid composition of soybean were taken as response variables in this investigation. The experimental design was randomized complete block design with three replications. The results revealed that SBM and CF recorded the tallest plants and first pod height respectively at both R1 and R5 growth stages, In addition, SBM remained superior for recording significantly higher leaf number at R1 and R5 and node number at R5 stage along with maximum pod number and seeds per pod. The maximum 1000 grain weight and grain yield were exhibited by LCBM which was followed by SBM. In addition, CBM gave the highest protein content while LCBM recorded the maximum oil percentage along with linoleic, mysteric and behenic acid contents, Furthermore, LCBM outperformed other fertilization regimes in terms of palmitoleic, stearic, linolenic and arachidic acids percentages along with oleic: linoleic acid ratio.

Comparing durum wheat cultivars by genotype x yield x trait and genotype x trait biplot method
(CHILEAN JOURNAL OF AGRICULTURAL RESEARCH, 2019) Kendal, Enver
The specification of the most convenient cultivars based on multiple trait indices is a new approach in durum wheat (Triticum durum Desf.) adaptation and stability studies. This approach helps to define the best cultivar based on multiple traits and multiple locations because cultivars are affected by unpredictable climatic conditions. Some traits (ears per square meter, spike length, number of grains per spike, spike yield, and leaf chlorophyll content among others) can be produced for primary breeding purposes because they are influenced by environmental factors and indirectly affect grain yield and quality. Therefore, in the present study, the new genotype × yield trait (GYT) biplot approach was used to identify the best cultivar among 10 durum wheat cultivars based on multiple environments (8) and multiple traits (18). Cultivar ranking was examined by a superiority index that combined yield and other target traits with the GYT biplot. The general adaptability of each cultivar in terms of all the traits indicated differences based on environment means, and significant differences were found between varieties for the GYT biplot. In the GYT biplot, yield-trait combinations clearly indicated the most stable cultivars, whereas in the genotype × trait (GT) biplot, the best cultivars were not defined for all traits. ‘Sariçanak’ was ranked as the best combination of physio-morphological traits with grain yield, ‘Zühre’ was the best for more quality traits, and ‘Güneyyildizi’ was the best for both physio-morphological and quality traits in the GYT biplot. The GYT biplot combines traits with yield and can help the visual identification of the best cultivars; it is better than the GT biplot method.

(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.

Effect of Different Harvest Dates to Essential Oil Components of Oil-Bearing Rose (Rosa damascena Mill.) in Mardin
(Taylor & Francis Online, 2022) İzgi, Mehmet Necat
Rosa damascena Mill. is the most prominent rose source for the manufacturing of rose oil, rose water, concrete, and absolute from flower petals. The purpose of this study was to see how different harvest dates affected the essential oil components and rates obtained from flowers in oil rose planted for the first time in Turkey's Mardin Province. Blossoms were taken five times with three replications, at around one-week intervals, from a garden in the Yaylabaşı district at 6:00 a.m. (4, 11, 18, 24, and 31 May). Animal manure and leonardite were used instead of chemical fertilizers for plants. No chemical pesticides have been applied. Essential oil components of the oils obtained by a water distillation system (Clevenger apparatus) were determined by GC/MS. The citronellol ratio, which is the most important component for the quality of the essential oil in the plant, was found to be highest (35.90%) in the first harvest period and lowest in the last harvest period (17.57%). Geraniol levels decreased in the first three harvests, with the greatest level (27.16%) coming in the last harvest. The percentages of citronellol/geraniol varied between 1.51 and 0.65 depending on the different harvest dates. Nerol rates peaked at 15.44% on the first harvest, progressively declined until the fourth harvest (7.92%), then slightly increased on the fifth harvest. Nonadecane continuously increased from the first to the last harvest (4.10%-11.66%). No methyl eugenol was detected. Mardin is a promising location for oil-bearing rose cultivation, given the essential oil components and their ratios.

The Effect of Different Phosphorus Doses on Agronomic and Quality Characteristics of Coriander (Coriandrum Sativum L.)
(Aloki Applied Ecological Research and Forensic Inst Ltd, 2020) Izgi, M. N.
In a two-year study, under the environmental conditions of the plains of Mardin province in Turkey, the effects of different doses of phosphorus (0, 30, 60, 90, 120 kg ha(-1)) on the yield and quality characteristics of the coriander (Coriandrum sativum L.) were examined. Plant characteristics such as plant height, number of branches, number of umbels, thousand seed weight and seed yield were examined, besides quality characteristics such as essential oil rate and composition. The essential oil was isolated with a Clevenger apparatus from mature fruits. Essential oil components were determined with Gas chromatography-mass spectrometry (GC-MS). The results revealed that phosphorus doses affect the plant characteristics of coriander including plant height, number of branches, number of umbels and thousand fruit weight with positive significance. Fruit yield was not affected significantly. Phosphorus doses had a significant positive effect on essential oil rate. Increasing phosphorus doses affected rates of alpha-pinene, geranyl acetate and camphor positively. However, Linalool and gamma-terpinene were not affected by phosphorus doses significantly. The application of 120 kg phosphorus per hectare, which had the highest essential oil rate in both years, can be recommended in coriander farming.

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.

EFFECTS OF DIFFERENT DOSES OF NITROGEN AND CHICKEN MANURE ON TIR WHEAT (Triticum aestivum L. var. leucospermum (K o r n.) F a r w.) YIELD AND YIELD COMPONENTS
(SCIBULCOM LTD, 2015) Toğay, Necat; Toğay, Yeşim; Doğan, Yusuf
Chicken manure is a concentrated and quick acting fertiliser. Application of chicken manure at optimum doses together with nitrogen fertilising may provide balanced significant increase of crop productivity and production quality. In this study, the effects of nitrogen doses (0, 40, 80, 120 and 160 kg nitrogen ha(-1) with sowing and 60 kg nitrogen ha(-1) top fertiliser with tillering season except control plots in total 0, 100, 140, 180 and 220 kg nitrogen ha(-1)) under the condition with chicken manure (10 t ha(-1)) and without chicken manure on yield and yield components of Tir wheat were investigated. Experiment was laid out in Split Plots Design in Randomised Blocks with 3 replicates in Yuzuncu Yil University, in 2009-2010 and 2010-2011 growing seasons. While the highest seed yield was obtained at the chicken manure and 180 kg ha(-1) nitrogen fertiliser as 2346 and 2073 kg ha(-1), repectively, the lowest seed yield was obtained without chicken manure and control as 1451 and 1270 kg he in years of 2011-2012 and 2012-2013, respectively. The results of the study indicated that nitrogen and chicken manure applications increased significantly the seed yield and yield components.

Effects of different nitrogen doses on thymoquinone and fatty acid composition in seed oil of black cumin (Nigella sativa L.)
(JAOCS, Journal of the American Oil Chemists' Society, 2021) Telci, İsa; Izgi, Mehmet Necat; Ozek, Temel; Yasak, Selma; Yur, Suleyman; Ozek, Gulmira
Black cumin, Nigella sativa L. belonging to Ranunculaceae, is a valuable medicinal plant because of the curative effects of seed and oil. Despite studies on black cumin, there are few studies on the effects of nitrogen on fatty acid composition, no records on thymoquinone yield, and the thymoquinone content of the seed oil. In this study, the effects of different nitrogen doses on the seed oil yield, thymoquinone ratio/yield, and fatty acid compositions were investigated. Field studies with nitrogen doses (0, 40, 60, 80, and 100 kg/ha) were studied using the randomized plot design. As a result of the research, nitrogen doses significantly affected the oil and thymoquinone yields while insignificant on the thymoquinone ratio. The highest oil yield with 501.6 kg/ha was obtained from 80 kg/ha of the nitrogen doses, while the highest thymoquinone yield with 10.24 kg/ha was obtained from the control plots. Thymoquinone yields were in the same statistical group with other nitrogen doses, except for means of 100 kg/ha nitrogen doses. Linoleic, oleic, and palmitic acids were major fatty acids of black cumin, and their variations were insignificant in nitrogen applications. The values of butyric, capric, and linolenic acids varied significantly in different nitrogen doses. As a result of the study, it was determined that the highest oil yield was obtained from 80 kg/ha nitrogen application. It has been determined that nitrogen doses above 60-80 kg/ha should be avoided for the seed oil and thymoquinone yields in black cumin.

Lentil (Lens culinaris Medic.) is an important food crop with high protein content. This study aimed to determine the effects of increasing doses of phosphorus and humic acid applications on P, K, Ca, Mg, Fe, Cu, Mn, Zn, protein ratio and seed yield in lentil cultivar. The study was carried out in the research and application during the 2008–2009 and 2009–2010 cropping seasons in field of Agriculture Faculty Yuzuncu Yil University, Turkey. The experiment comprised a factorial randomised complete block design replicated three times with three phosphorus treatments 0, 40 and 80 kg ha–1, as triple superphosphate, and three humic acid treatments 0, 300 and 600 kg ha–1. For basic fertilisation 40 kg ha–1 ammonium sulphate were applied for nitrogen. The nutrient contents of seed and yield were significantly increased by increasing phosphorus and humic acid levels except for Zn content nutrient. The combination between phosphorus at 80 kg P2O5 ha–1 and humic acid at 600 kg ha–1 gave the highest growth and production as well as minerals composition (P, K, Ca, Mg, Fe, Cu and Mn) and protein content compared to other treatments. Humic acid increased the availability of phosphors, macronutrients and micronutrients. © 2016, Scibulcom Ltd. All rights reserved.
