In this study, canonical correlation (CCA) was used to examine the associations between the soil parameters (X set) of the Amik plain and the fractions of selenium (Se) (Y set). A statistically significant correlation (P < 0.01) of 0.391 ± 0.06 was observed between the first canonical variable pair (FCVP). The clay, sand, and silt variables exhibited the greatest standardized canonical coefficients, with values of 74.55, 75.83, and 94.77, respectively. Additionally, the B3 percent had a standardized canonical coefficient of 1.029. The analysis of the FCVP showed that the original variables of the X set and/or its canonical variable (U1) had the strongest linear connection (0.770) with organic matter (OM) and the B3 percentage in the Y set (0.603). The OM (0.3012) exhibited the most substantial linear structural correlations between the canonical variables of the Y set and the original variables of the X set. However, the canonical redundancy analysis revealed that in the FCVP, the variance of the X set was described by its canonical variables to the extent of 20.97%, whereas the Y set was explained by 21.96%. Hence, it can be inferred that the use of canonical correlation is effective in elucidating the relationship between soil parameters and various components of plant nutrition.","PeriodicalId":119729,"journal":{"name":"Soil Studies","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139282869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, significant reductions in yield and marketable fruit quality were observed under stress conditions that exceeded the tolerance level. Eggplant has wild relatives which are known as tolerant to stresses. As a part of the comprehensive project this research includes drought-tolerant line development from the F4 population obtained by interspecific crossing between Solanum incanum L., a wild relative of eggplant naturally distributed in the Sub-Saharan zone, and a pure line with superior characteristics developed in BATEM. Qualified 50 inbred lines were selected as drought tolerant among F3 progenies in previous studies. In this experiment, 12 plants from each 50 genotypes at F4 level were exposed to drought stress, which was created by 25% watering of full irrigation. On the 25th day of treatment, tolerant plants were distinguished by using 0-5 scale. From each genotype, 4 plants were selected as drought tolerant, and they were transferred to greenhouse to identify their heat tolerance. Among the drought-tolerant group 42 F4 lines were found as heat tolerant.","PeriodicalId":119729,"journal":{"name":"Soil Studies","volume":"100 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139349500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The morphological and metabolic characteristics of the isolates were tested under laboratory conditions. According to molecular identification, eight bacterial isolates were identified as Agrobacterium tumefaciens, and two isolates (F4DC and F6DC) were identified as Rhizobium gallicum. Field experiments were carried out to compare the effect of one native rhizobia (Rhizobium gallicum F4DC), chemical fertilizer, and nonfertilizer control in SFWRRI Sarayköy Research and Application Station in Ankara. Our results show that sugar bean (Phaseolus vulgaris L.) inoculation with Rhizobium gallicum F4DC (MZ156852) induced a significant increase in the number of nodules, grain yield, number of pods, and plant height compared to the control. These results show that Rhizobium gallicum F4DC is a suitable choice for use in symbiotic association with beans to work as a biofertilizer.","PeriodicalId":119729,"journal":{"name":"Soil Studies","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139355540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the key factors that shape the composition and function of the rhizosphere microbiome is root exudates, the complex mixture of organic compounds released by plant roots. Root exudates serve as a source of energy and nutrients for the rhizosphere microbiome, as well as a means of communication between plants and microbes. The dynamic interplay between root exudates and rhizosphere microbiome is a complex and highly regulated process that involves multiple feedback loops and interactions. Recent studies have revealed that the composition and quantity of root exudates are modulated by a range of biotic and abiotic factors, including plant genotype, soil type, nutrient availability, and microbial community structure. In turn, the rhizosphere microbiome can influence the production and composition of root exudates, through processes such as nutrient cycling, plant hormone synthesis, and modulation of plant defense responses. Understanding the dynamics of root exudates and rhizosphere microbiomes is crucial for developing effective strategies for microbiome engineering, plant-microbe symbiosis, and sustainable agriculture. This review provides an overview of the current state of knowledge on the dynamic interplay between root exudates and rhizosphere microbiomes, highlighting the key factors and mechanisms that govern this complex relationship.","PeriodicalId":119729,"journal":{"name":"Soil Studies","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139355266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was performed under greenhouse conditions using surface soil samples and 1.5 kg pots. Furthermore, the study was planned as an incubation experiment and the application of PVA, PAM, and HA at 500, 100, and 500 ppm doses for each soil texture class, respectively. During the incubation times (1 (0), 2 (15), 3 (30) 30, and 4 (45) days), the irrigation process was repeated as half of the available moisture in the soil was depleted. Ultimately, the applications of PVA, PAM, and HA on soils in sandy loam, loam, and clay textures increased the liquid limit/ pF'2 moisture ratio (LL/pF'2) values in them by 6.30%, 5.99%, and 7.30%, respectively, (reducing the tendency to dispersion) compared to the control. Furthermore, the applications increased the plastic limit/pF’2 moisture ratio (PL/pF’2) values (resistance to mechanical forces) by 22.31%, 16.50%, and 9.27%, respectively. Incubation time 1 was more effective in reducing dispersion and increasing resistance to mechanical forces, and the effects decreased over time.

The average annual temperature is 12.52 °C and the annual average rainfall is 518 mm. According to the Newhall simulation model, soil temperature and moisture regimes are Mesic and Typic Xeric, respectively. Field observations and investigation of topographical, geological, and geomorphological maps, 16 soil pedons were described. Soil samples were taken from each pedon based on the genetic horizon and laboratory analyzes were performed. The detailed field study was carried out by considering the grid method and auger examination. The determination and description of 16 soil series were made by evaluating the findings of analyses and field research. Due to their quick pedological processes, six of them were classified as Entisol, six as Inceptisol, three as Verisol, and one as Alfisol. Vertisols cover about 35.63% of the total area followed by Inceptisols at 22.3%, Entisols at 22.3%, and Alfisol at 13.58%. As for FAO-WRB classification system, soils were classified as Vertisol, Cambisol, Leptosol, and Luvisol.
