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.

(Corvinus University of Budapest, 2019) Dogan, Y.; Togay, N.; Togay, Y.; Doğan, Yusuf
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-P2O5 - 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. © 2019, ALÖKI Kft., Budapest, Hungary.
First report of Neoscytalidium novaehollandiae on common sage (Salvia officinalis)
(Springer link, 2021) Dervis, Sibel; Guney, Inci Guler; Kosar, Islim; Bozoglu, Tugba; Ozer, Goksel
In June 2020, many plants exhibited symptoms of root rot and foliar blight in the experimental field of common sage in Sanliurfa province, Turkey. The pathogen was identified as Neoscytalidium novaehollandiae based on morphological characteristics and phylogenetic analysis of partial sequence of the transcription elongation factor 1-alpha gene and the internal transcribed spacer of rDNA. Koch's postulates were fulfilled by successful re-isolation of the pathogen from inoculated plants in the pathogenicity assay. To our best knowledge, this is the first report of N. novaehollandiae causing root rot and foliar blight of common sage worldwide.

(University of Montenegro, 2021) Düzgün, M.; Kendal, E.; Zahir Düz, M.; Hatipoğlu, A.
The purpose of this study was to determine the content of some macro and trace elements in grain of spring barley cultivars, and to state the relationships between those elements. In this study macro and trace elements (Ca, K, Mg, Fe, Zn, Mn, Si, Sn, Cu, Cr, Cd, Ni, V, Pb, As and Se) of barley cultivars were determined by inductively coupled plasma optic emission spektometry (ICP-OES) using grain. The grain samples were digested by microwave system, as well as. As and Se were determined by hydride system. The result of study showed that the content Si of barley cultivars are quite high, however, the concentrations toxic heavy metals of Cd, Pb and as were determined to be below the limit values. The biplot indicated that three group occurred among macro and trace element and the correlation of Zn with Sn, Cr with Ca and Fe, Ca with Fe and Pb was significant and positively, while V with Si was significant and negatively. On the other hand, the study showed that Samyeli is the best cultivar based on macro and trace element concentrations and this variety can be used in animal husbandry. © 2021, University of Montenegro.

(NORDIC JOURNAL OF BOTANY, 2021) Kılıç, Murat; Mungan Kılıç, Fatma
The nutlet (mericarp) morphology of nine species of Salvia sect. Salvia (Salvia bracteata Banks & Sol., Salvia macrochlamys Boiss. & Kotschy, Salvia suffruticosa Montbret & Aucher ex Benth., Salvia trichoclada Benth.), Hymenosphace (Salvia multicaulis Vahl), Aethiopis (Salvia montbretii Benth., Salvia palaestina Benth., Salvia syriaca L.) and Hemisphace (Salvia russellii Benth.) (Lamiaceae) has been studied by scanning electron microscopy (SEM), and a detailed description of the nutlet morphological features of all examined taxa is provided. The basic shape of nutlets in most species is subprolate or prolate and the size ranged between 3.02 and 6.47 mm in length and between 1.78 and 5.10 mm in width. Three basic types of sculpturing can be distinguished: colliculate, reticulate and verrucate. The colliculate type is the most common among the studied species. The colliculate type is characteristic for sect. Salvia. Subsection Salvia with colliculate/slightly furrowed sculpturing is easily distinguished from the other subsections. The systematic and biological implications of the nutlet characteristics are shortly discussed. © 2021 Nordic Society Oikos. Published by John Wiley & Sons Ltd
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.
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.
