Green Synthesis, Characterization and Antimicrobial Activity of Silver Nanoparticles (AgNPs) from Maize (Zea Mays L.)
(Aloki Applied Ecological Research and Forensic Inst Ltd, 2019) Eren, A.; Baran, M. F.
In recent years, the biosynthesis (green synthesis) of metal nanoparticles such as silver nanoparticles (AgNPs) have become one of the safest, most cost-effective and environmentally friendly approaches. In this study, AgNPs were synthesized using maize (Zea mays L.) leaves. For the characterization of synthesized AgNPs different techniques were used, such as X-ray diffraction spectroscopy (XRD), Ultraviolet visible (UV-Vis) spectroscopy, transmission electron microscopy (TEM), Energy dispersive X-ray spectroscopy (EDX), Fourier-transformed infrared spectroscopy (FT-IR) and Thermal gravimetric and Differential thermal analysis (TGA-DTA). The XRD results showed that AgNPs had a mean diameter of 12.63 nm and a crystal-like appearance. In addition, antimicrobial activities of synthesized AgNPs were evaluated using 3 different antibiotics against Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus bacteria and Candida albicans yeast. Antifungal activity of AgNPs with antibiotics has been observed to be better than the antibiotics against Gram-positive and Gram-negative bacteria. The minimum inhibitory concentrations were found to be 0.084, 0.337 and 0.021 mg mL(-1) for Escherichia coli, Staphylococcus aureus, and Candida albicans, respectively. The results revealed that AgNPs synthesized from maize leaf extract have antibacterial activity against Gram-negative Escherichia coli, Gram-positive Staphylococcus aureus and antifungal activity against Candida albicans yeast, and that the produced AgNPs could be used in the production of biomedical products and in the pharmaceutical industry.

(Aloki Applied Ecological Research and Forensic Inst Ltd, 2019) Acay, H.; Baran, M. F.; Eren, A.
In this study, a direct approach to fabricating silver nanoparticles (AgNPs) via the leaf extract of common grape (Vitis vinifera) has been demonstrated. The produced particles were found with a maximum wavelength of 452.47 nm, spherical shape and the crystal size of 18.53 nm through UV-Visible spectrophotometry, XRD (X-ray diffraction) and SEM (Scanning electron microscopy) characterization methods. Furthermore, the functional groups involved in the reduction were specified with FTIR (Fourier transform infrared spectroscopy), the elemental compounds were identified with EDX (Energy dispersive X-Ray spectroscopy) and the degradation points were determined with TGA-DTA (Thermal gravimetric analysis) methods. AgNPs were found to be effective against hospital pathogens, namely Gram-negative Escherichia coli ATCC 25922, Gram-positive Staphylococcus aureus ATCC 29213 and Candida albicans fungus at the concentrations of 0.314, 0.078 and 0.334 mu g mL(-1), respectively.

Effect of Nitrogen Fertilization Levels on Grain Yield and Yield Components in Triticale Based on AMMI and GGEBiplot Analysis
(Aloki Applied Ecological Research and Forensic Inst Ltd, 2018) Oral, E.
This study examined the effects of nitrogen doses rate on grain yield (GY) and yield components of spring triticale (xTritico secale) cultivars in dry area, based on cultivars plus cultivar x nitrogen doses interaction GGE biplot and AMMI analysis. The research was designed to evaluate the effects of different nitrogen fertilization levels (0, 40, 80, 120 and 160 kg ha(-1) of N) on the grain yield and agronomic performance of two cultivars in two growing seasons (2015-16/2016-17). Split plot layout with in randomized complete block design with 3 replications was used in both years. The response to fertilization levels were evaluated through GGE (Genotype main effects and Genotype x Environment interaction) biplot graphic methodologies and regression. Combined analysis of variance of nitrogen applications of two cultivars showed highly significant (p < 0.01) difference between the cultivars, nitrogen applications and interaction. The grain yield of triticale was most of all affected by cultivars (70.8%) and then by nitrogen doses (23.5%) and interaction (5.7%). On the other hand, the study showed that plant height, number of spikes per m(2), number of grain of ears and grain yield increased depending on the increasing nitrogen doses of the cultivars. The highest performance of grain yield of both cultivars were associated with nitrogen N-3 (120 kg/ha) fertilization in regression and AMMI analysis. The results showed that 80 kg/ha N application can be recommended in triticale traits and grain yield with Esin (new) cultivar. Further more, we found that the GGE biplot method generated highly useful results with high visual quality in the study.

Effect of Fertilization and Seed Size on Nodulation, Yield and Yield Components of Chickpea (Cicer Arietinum L.)
(Aloki Applied Ecological Research and Forensic Inst Ltd, 2017) Aktas, H.; Nadeem, M. A.; Erdemci, I
This study investigated the effects of seed size and fertilizer usage with seed at planting on agronomic parameters of chickpea as a winter crop. The experiment was conducted according to split-split plots of randomized blocks with four replications. As factorial two chickpea varieties (Arda and Diyar 95), two fertilizer applications (with and without fertilizer) and three seed sizes (large, medium and small) are discussed in this study. The results showed that fertilizer applications along with seed at planting and large seed increased significantly the number of seed per plant, number of pods, biological yield, grain yield and 100-grain weight. However, fertilizer applications with large seeds had a negative effect on the output of the seeds and reduced grain yield per unit. In general, plants germinating from large seed had higher number of pods and number of seeds plant(-1), 100 seed weight, biological and seed yield plant(-1), while plants germinated from medium seed had higher emergence percentage, first pod hight, nodule fresh weight plant(-1) and grain yield ha(-1). These effects tend to decrease in chickpea varieties having medium-grain weight as Arda. It was concluded that, application of fertilizer along with seed during the sowing time results in decreased emergence percentage of the seeds and lower the yield in chickpea.

The Effects of Nickel Applications on the Growth of Cocklebur (Xanthium Strumarium L.) Plant
(Aloki Applied Ecological Research and Forensic Inst Ltd, 2019) Eren, A.
Nowadays the environmental pollution caused by heavy metals is spreading all over the world, especially where the industry is developing rapidly, and soils are polluted very dramatically and hazardously at a high level. In this study, cocklebur-(Xanthium strumarium L.) plants were grown in nickel (Ni) contaminated soil (0, 50, 100, 200 and 400 mg Ni kg(-1)) under greenhouse conditions for 6 weeks to study the ability of Ni uptake and accumulation of the plants. The Ni treated plants were compared with the control (0 mg Ni kg(-1)) plant. As a result of that comparison, chlorophyll levels of old and young leaves, dry weights, reduced glutathione (GSH), macronutrient concentrations, such as nitrogen (N), phosphor (P), potassium (K), calcium (Ca) and magnesium (Mg)) and micronutrient concentrations, such as iron (Fe), zinc (Zn), and manganese (Mn) nutrient concentrations of the plants were decreased, whilst the concentrations of Ni and of copper (Cu) increased with increasing dose of Ni application. The results show that the studied plant (Xanthium strumarium L.) can be used for the cleaning up of Ni-contaminated soils and is suitable for phytoremediation.

(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.

(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.

(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.

Effects of Nitrogen Fertilization on Coriander (Coriandrum Sativum L.): Yield and Quality Characteristics
(Aloki Applied Ecological Research and Forensic Inst Ltd, 2020) Izgi, M. N.
Coriander (Coriandrum sativum L.) is a spice plant belonging to the Apiaceae family. In this study, the aim was to specify the effects of different nitrogen doses on the yield and quality properties of coriander. In this research; plant height, number of branches, number of umbels, thousand seed weight, seed yield, oil content, fatty acid composition, essential oil rate and essential oil composition were examined. The essential oil contents in coriander fruits was determined by Clevenger apparatus. Fatty oil was isolated by cold press. Essential oil and fatty oil compositions were determined by Gas chromatography-mass spectrometry (GC/MS-QP2020) device. While nitrogen doses did not positively affect fruit yield, they had a significantly positive effect on the herbal characteristics of coriander (plant height, number of umbels and thousand fruit weight). It was revealed that nitrogen doses had positive significant effect essential oil rate. Increasing nitrogen doses affected rate of linalool. Nitrogen doses had a significant effect only on butyric acid, and for fatty oil rate and other major fatty acids their effect was not significant. It has been determined that high fruit yields are obtained at 60 and 80 kg ha(-1) nitrogen applications and that the rate of essential oil and linalool is the highest at 100 kg ha(-1) nitrogen doses especially in the second year.
