Öğe Alleviation of salt stress by increasing potassium sulphate doses in four medicinal and aromatic plants(Taylor & Francis As, 2018) Yaldız, Gülsüm; Özen, Ferit; Çamlıca, Mahmut; Sönmez, FeritIn this study, the effects of potassium doses (control, 150, 300 and 450mg K2SO4 kg(-1)) and salt stress (control, 100mM NaCl) on the yield and some element content of four medicinal and aromatic (Coriandrum sativum, Anethum graveolens, Ocimum basilicum and Foeniculum vulgare) plants were investigated in climate chamber. Both salinity and K fertiliser levels affected the fresh and dry weight of all evaluated plants. Anethum graveolens, Ocimum basilicum species are more sensitive to salinity, particularly at the vegetative productive stages. The highest fresh and dry weights of leaves, stems, roots and herb in Coriandrum sativum and Foeniculum vulgare species was observed in 300mgkg(-1) fertiliser applications. In general, there was a relatively consistent and positive correlation between root element content and aerial parts element content. The result of the present study showed that NaCl treatment caused an increase in Na+ concentration, and a decrease in K+ and Ca+2 concentration in Coriandrum sativum, Anethum graveolens, Ocimum basilicum and Foeniculum vulgare. There was an interaction between K2SO4 application and salinity effects on Na+ concentration in the all evaluated plants. Given the experimental results, especially Foeniculum vulgare and Coriandrum sativum species were the most resistant to salt stress.Öğe Artan dozdaki biyokömür ve solucan gübresi uygulamalarının buğdayda ve toprakta besin elementi içeriği üzerine etkilerinin belirlenmesi(2019) Sönmez, Ferit; Çığ, FatihDeneme Bolu Abant İzzet Baysal Üniversitesi, Ziraat ve Doğa Bilimleri Fakültesine ait iklim odasında yapılmıştır.

Experiment was conducted as a randomized complete block design with 3 replications. At the end of the study, it was seen that Rhizobium inoculation affects the N, Mg, and Pb contents of the lentil straw on by P<0.05, P and Ca contents by P<0.01 in the first year; the N, Fe, and Zn contents on P<0.05 level, on the Pb content P<0.01 level in the second year. Lentil grains were affected only on the K, Fe, Pb, and Cd contents by P<0.05. Sewage sludge applications were used to detect the effects on the N, Mg, Fe, Mn and Cu contents of the lentil straw by P<0.01, Co content by P<0.05, and Pb content by P<0.01 in first year; on the N, K, Zn and Pb contents by P<0.01, P and Mn contents by P<0.01, on the Mg, Fe, Cu, and Co contents by P<0.05 in the second year. Effects received by the lentil grains are as follows: The N, K, and Cu contents by P<0.01, on the Pb, Fe, P, and Mg contents by P<0.01, on the Ca and Zn contents by P<0.05 in the first year; on the P, K, Ca, Mg, Fe, Mn, Zn, Cu and Co contents by P<0.01, on the Pb content by P<0.05 in the second year. The effects of inoculation on the lentil straw and grain, regarding the nutrient and heavy metal contents were determined to be insignificant. This result may be a result of weak inoculation application and the heavy metal content of the sewage sludge, as well as the negative effects of Rhizobium inoculation.Öğe Effect of biochar and PGPR on the growth and nutrients content of einkorn wheat (Triticum monococcum L.) and post-harvest soil properties(MDPI, 2021) Çığ, Fatih; Sönmez, Ferit; Nadeem, Muhammad Azhar; Sabagh, Ayman ElLimited availability of nutrients to crops is a major agricultural concern. Deteriorated soil health and poor fertility status decrease the bioavailability of essential nutrients to the plants. Consequently, organic soil amendment biochar is gaining attention due to its potential benefits. Rhizobacterial inoculation, are also documented as an effective technology for mobilization of immobile nutrients in soil. However, limited literature is available on combined use of rhizobacteria and biochar. Therefore, this study was carried out to examine the changes in the nutrient content of einkorn wheat and the change in some soil properties during the application of plant growth-promoting rhizobacteria (PGPR) with biochar. Four doses of biochar (0, 2.5, 5, and 10%) were applied with and without PGPR in the study. Biochar increased the growth criteria such as plant fresh weight (PFW), plant dry weight (PDW), root fresh weight (RFW), root dry weight (RDW), number of tillers, germination rate (GR) and potassium (K), calcium (Ca), sodium (Na), iron (Fe), copper (Cu), zinc (Zn), manganese (Mn), and nickel (Ni) elements. While PGPR application increased soil pH, dry and fresh weight of root, R/S, K, Ca, Mg, Fe, and Ni contents, and it caused a decrease in PH, PFW, tillers, GR, P, Cu, and Zn values. Combined biochar applications and PGPR had a significant effect on the pH, RFW, R/S, P, Na, and Cu. In conclusion, the combination of biochar and PGPR applications has shown a positive effect in terms of soil properties, plant growth, and element contents of einkorn wheat.Öğe Effect of Phosphorus and Molybdenum Applications on Macro and Micro Nutrient Content of Bean (Phaseolus vulgaris) Straw and Grain(2024) Erman, Murat; Çiğ, Fatih; Sönmez, Ferit; Ceritoglu, MustafaThe aim of this research is to investigate the effect of phosphorus and molybdenum treatment on macro and micronutrient biofortification in bean. The study sheds light on the individual and interactive effects of phosphorus and molybdenum on macro and micronutrient uptake and biofortification in Phaseolus vulgaris. Three levels of phosphorus and molybdenum were used in the experiment laid out in a randomized block design with four replications. Phosphorus and molybdenum treatment promoted nitrogen accumulation in both straw and seed. Nitrogen content increased with rising phosphorus doses in straw and seed over control by 42.3% and 7.4%, respectively. Moreover, phosphorus addition increased straw manganese content while molybdenum enhanced straw manganese. In addition, 4 g Mo kg-1/seed treatment boosted seed magnesium concentration over control by 28.2%, however, no phosphorus, potassium, copper, iron, and zinc in the plant materials, likely due to the sufficient levels of these nutrients in the soil composition of the experimental area. According to results, nitrogen, phosphorus, potassium, calcium, magnesium, manganese, copper, iron, zinc varied in straw and seed between 3.15-7.05% and 17.5-19.2%, 586-990 ppm and 1049-1355 ppm, 695-2690 ppm and 1021-1727 ppm, 5839-11162 ppm and 559-1303 ppm, 690-1474 ppm and 348-1036 ppm, 25.3-38.3 ppm and 8.29-9.29 ppm, 8.6-16.9 ppm and 11.3-19.9 ppm, 469-927 ppm and 70.2-80.3 ppm, 6.5-10.8 ppm and 17.9-23.3 ppm, respectively. Consequently, it has been determined that molybdenum supplementation is necessary along with phosphorus fertilization in areas where beans are grown, especially in acidic soils.Öğe The effect of potassium and humic acid applications on yield and nutrient contents of wheat (Triticum aestivum L. var. Delfii) with same soil properties(Taylor & Francis Inc, 2019) Dinçsoy, Mehmet; Sönmez, FeritThis study was conducted in the farmer field between the years 2014 and 2015. In this study, 3 doses of potassium (K) (0, 10, and 20 kg da(-1)) of K2SO4 (50% K2O) fertilizer and 3 doses of humic acid (HA) (0, 20, and 40 kg da(-1)) (85% HA) were used. Increase in the HA dose reflected significant effects on pH, salt, organic matter, phosphorus, magnesium, iron, and manganese contents of the experiment area at p < .01 level. It was determined that increased potassium applications affected the salt, magnesium (Mg), iron (Fe), and copper (Cu) contents at p < .01 level. Increased HA application on plant growth criteria had a significant effect on biological yield, grain yield, and harvest index (p < .01). However, K did not reflect any effect on the growth stage of wheat. Increased number of HA applications on grain and straw nutrient content were found to have significant (p < .01) effects on P, K, Ca, Mg, Fe, and Zn. Increased potassium applications had an effect on the P, K, Mg, Fe, and Zn contents with a significant level (p < .01). It was observed that HA applications were more effective than potassium applications on both general soil properties and yield and nutrient content.Öğe Effect of storage conditions on nutritional quality and color characteristics of quinoa varieties(Elsevier, 2021) Kibar, Hakan; Sönmez, Ferit; Temel, SüleymanTo maintain grain quality and prevent loss, effective storage systems are required. The aim of this study was to evaluate the effects of storage duration (0, 60, 120, 180, 240, 300, 360 days) and temperature (4, 10, and 25 °C) on proximate and nutritional components, and color properties of Mint Vanilla and Titicaca quinoa varieties. The results showed that the increase in storage duration and temperature leads to changes in the grain moisture, protein and ash contents, nutritional component and color properties. There was an increase in ash content at 25 °C, moisture content at 10 and 25 °C, and protein content at 4 °C in the stored grains compared with the grains on the initial of storage for Mint vailla variety. Whereas, there was an decrease in ash and protein content for all the temperature at the end of 360 days storage for Titicaca variety. Overall, there was a decrease (except Fe, Zn, Co, Ni, Cd and Pb) in the nutritional component of both quinoa varieties. L?, H° and WI values decreased, and a?, b? and C? values increased as a function of storage duration and temperature and showed some temperature-dependent degradation for both quinoa varieties.Öğe Effects of ameliorative applications on photosynthetic pigments and some leaf properties of barley (Hordeum vulgare L.) under salt stress(Parlar Scientific Publications (P S P), 2021) Sönmez, Ferit; Kılıç, Özlem GürbüzThe aim of this study was to determine the effects of potassium, zinc and mycorrhiza applications on chlorophyll -a (Chl-a), chlorophyll -b (Chl-b), total chlorophyll (total Chl), chlorophyll a/b (Chl-a/b) and Total carotenoid (TC), leaf area index (LAI), sub stomata number (SSN), upper stomata number (USN) and germination rate (GR) in salt -stressed barley (Hordeum vulgare L.).

This study evaluated the impact of Se treatments, comprising sodium selenite (selenite) and sodium selenate (selenate) forms, on the growth of 10 plant pathogenic fungi. Materials and Methods: The impact of Se treatments on the mycelial growth and sporulation of fungi was assessed in in vitro conditions. Probit analysis was used to determine the concentrations of salts that induced a 50% reduction (EC50) in both mycelial growth and sporulation of fungi. Results: At the highest concentration (120 ppm), selenite demonstrated inhibitory effects on mycelial growth across various species, with a reduction in growth ranging from 6.82% to 62.46%. In contrast, selenate exhibited a broader spectrum of inhibition, affecting mycelial growth from 0% to 87.14%. Across different concentrations, Fusarium pseudograminearum displayed the highest sensitivity to selenite (EC50<24 ppm), followed by Bipolaris sorokiniana and Verticillium dahliae. Similarly, Colletotrichum coccodes exhibited the highest sensitivity to selenate treatment (EC50<24 ppm), followed by B. sorokiniana, Botrytis cinerea, Sclerotinia sclerotiorum, and V. dahliae. Both salts effectively inhibited sporulation across fungal species, with no significant difference observed. Colletotrichum coccodes, F. pseudograminearum, B. cinerea, F. culmorum, V. dahliae, and B. sorokiniana were significantly inhibited by selenite, while F. oxysporum exhibited lower inhibition. Similarly, these species, along with V. dahliae and F. oxysporum, were significantly inhibited by selenate, with slight differences between their inhibition percentages. EC50 values below 24 ppm were observed for C. coccodes, B. cinerea, F. culmorum, B. sorokiniana, and F. oxysporum, indicating potent inhibition of sporulation by both salts. Fusarium pseudograminearum required slightly higher concentrations for 50% inhibition. Verticillium dahliae showed higher sensitivity to selenate than selenite, with EC50 values of 33.16 ppm and below 24 ppm, respectively. Conclusion: The findings of this study contribute to our understanding of Se's antifungal potential across diverse plant pathogenic fungal species in sustainable agriculture. Further research is warranted to elucidate its mechanisms and optimize treatment protocols for disease management.
