Öğe IMPACT OF BORON APPLICATION ON YIELD AND MINERAL NUTRITION OF WHEAT(Parlar Scientific Publications (P S P), 2021) Yalcin, Mehmet; Konuskan, OmerFoliar application of boron plays an important role in the enhancing of growth and yield of wheat. This study was conducted in the field with consecutive two years (2017-2018) to examine foliar boron fertilization to improve grain yield and grain quality in eastern Mediterranean conditions. The experiment was arranged splits- plots design with three replicates. In wheat production, it was determined that boron application increases the grain yield as well as B, Ca and Fe content in the grain. Our results indicated that boron application produces a positive impact on wheat growth and productivity in the years with little rainfall. The control treatment (no B application) produced the lowest grain yield which was significantly lower than the yield observed with the soil treatment. Boron application improved an effective way in wheat and improvement in nutritive values by B application.Öğe Mapping the salinity of common soil groups of siverek district of sanliurfa province by geographical information systems (GIS)(Parlar Scientific Publications, 2020) Karaduman, Hamza; Yalcin, MehmetThis study aims to determine the salinity status of the common soil groups of Siverek district of Sanliurfa by mapping with Geographic Information Systems (GIS).For this purpose, a total of 76 soil samples were taken from 38 different points in the depths of 0-20 and 20-40 cm, representing the common soil groups of Siverek district of Sanliurfa province. pH, cation exchange capacity (CEC) and exchangeable cation (DK) values were determined in order to determine some properties of soils.In order to determine the salinity status of soils, properties such as total salt, salinity class, sodium adsorption rate (SAR), changeable sodium percentage (ESP) and soluble cations (Na, Ca and Mg) were determined.

Copper, iron or mangan was available in all soil samples. It. was found that there was a negative relations of total nitrogen content. with salt contents, available phosphorus with pH and clay contents, changeable potassium with sand contents, available copper and iron with pH and sand contents, available mangan with pH values and calcium with sand contents. It. was determined that there are positive relations of total nitrogen, changeable potassium and available iron with salt, silt., organic matter and KDK values, available phosphosrus with salt, silt and organic matter content, available copper and calcium with salt, clay, silt, lime, organic matter and KDK values and available mangan with organic matter.Öğe Quality of shallow groundwater and drainage water in irrigated agricultural lands in a Mediterranean coastal region of Turkey(Springer, 2006) Odemis, Berkant; Bozkurt, Sefer; Agga, Necat; Yalcin, MehmetSpatial and seasonal differences in water quality of drainage water and unconfined shallow groundwater were related to irrigation in Samanda. g, a Mediterranean coastal region. Eighteen wells, seven drainage points and Orontes River were monitored bimonthly for one year for analyses of electrical conductivity (EC), total dissolved solids (TDS), sodium adsorption ratio (SAR), cations (Na, K, Ca + Mg) and anions (CO3, HCO3, Cl and SO4). Agricultural irrigation using saline groundwater decreased water quality of Orontes River during the irrigation season ( May to September) more than during the non-irrigation season ( October to April). Seasonal fluctuations in water quality of shallow groundwater were greater during the irrigation season than the non-irrigation season in the study area. Excessive use of groundwater resulted in a decline in the water table levels in the irrigation season. Water table level rose up to the soil surface in areas where there was a lack of drainage or poor drainage, due to the impact of precipitation in the winter. SAR and pH values of drainage water increased in the irrigation season, while the other properties of drainage water decreased. Irrigation water quality of Orontes River was classified as C3S1 in both seasons. Irrigation water quality of shallow groundwater and drainage water varied from C2S1 to C4S2 in one year. Drainage and well waters were found to be different on yearly basis in terms of Na, SAR (p < 0.01) and Ca + Mg concentrations (p < 0.001). Ca + Mg concentrations for both sources were different for all sampling dates (p < 0.001).Öğe SPATIAL AND TEMPORAL VARIATIONS OF WATER QUALITY PARAMETERS IN ORONTES RIVER (HATAY, TURKEY)(Parlar Scientific Publications (P S P), 2009) Agca, Necat; Odemis, Berkant; Yalcin, MehmetOrontes (Asi) River, which is one of the important water Sources in the Middle East. rises in Lebanon, runs through Syria and Turkey and discharges into the Mediterranean Sea at the southern edge of Samandag, Hatay in Turkey. In this study, it is purposed to determine spatial and temporal variations of physicochemical properties and metal contents of Orontes River. Water samples were taken from 12 sampling sites on the Orontes River at six different periods. Water temperatures were measured at each site at the sampling times. Electrical conductivity (EC), pH. total dissolved solids (TDS), Na, K, Ca, Mg. Al, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, P, Pb, Zn, CO(3), HCO(3), and Cl determinations: were made on the water samples. Heavy metal concentrations of the Orontes River were found to be considerably low owing to the relatively low industrial activity in the basin. However, the presence of high concentrations of P especially around Antakya city was possibly due to the untreated sewage sludge discharge into this river. The seasonal and spatial fluctuations in the pH values were not excessive. The EC values at the sampling sites were found to be on the higher range in terms of salinity (754.5-1699.6 mu S cm(-1)). Both the EC and TDS values increased markedly in the rainy season probably due to the contribution of salts leaching from nearby lands. It can be concluded that soluble salts and the high P content are the most critical respective parameters threatening the agriculture and aquatic life in the lower Orontes River basin.Öğe Spatial distribution of heavy metals content in soils of Amik Plain (Hatay, Turkey)(Springer, 2011) Karanlik, Sema; Agca, Necat; Yalcin, MehmetThe purpose of the study was to investigate the total and bio-available contents of heavy metals (Cd, Co, Ni, and Pb) and to determine their spatial variability in the Amik Plain, Turkey. Samples of surface and subsurface soil were collected at 132 sites in the research area. All of the total metal concentrations except Ni were considerably lower than their maximum allowable concentrations. Mean available Pb concentrations at both depths were above the permissible limits, while the other metal concentrations were within the proposed limits. Semivariograms of all the total metal contents, pH, and available Ni and Pb content were best fitted to spherical models, while available Cd and Co contents were best fitted to exponential models. Block kriging was used to interpolate values at unmeasured locations, generating maps of spatial variation for each heavy metal and pH.Öğe Spatial distribution of heavy metals in common soil groups of Siverek District in Turkey(Parlar Scientific Publications, 2020) Yalcin, MehmetThe objective of the study was to investigate the heavy metal contents of common soil groups and spatial distribution in agricultural land of Siverek district in Sanliurfa, Turkey. A total of 76 soil samples in Siverek district of Sanliurfa province was obtained from two depth ranges (0-20 and 20-40 cm) and 38 separate spots in order to represent common soil groups. Salt, texture (clay, sand and silt), pH, line (CaC03), organic matter (OM) and heavy metal (Cd, Co, Cr, Ni, Cu, Fe, Mn and Zn) content were determined in samples. Descriptive statistics and correlation analysis were performed in transformed data from the soils of field of study. Maps of spatial distribution of heavy metal concentrations generated using kriging interpolation of data from two different depths (0-20 and 20-40 cm). Average pH, salt, lean and organic matter contents of soil were between 7.54-7.57, 0.06-0.06%, 3.64-3.84% and 1.89-1.99%, respectively. Ranking of average heavy metal values in research soils (0-20 and 20-40 cm) were Mn > Fe > Cu > Ni > Zn > Co > Cd > Cr. Semivariogram ranges for heavy metal content of research soils which defines maximum distance of spatial correlation was between 16 and 64 km. A positive correlation between Cd with Ni, Cu, Mn and Zn contents of soils was determined according to the results. Strong and weak heavy metal profiles of common soil groups in Siverek district of Sanliurfa exhibited as a result using heavy metal data sets and kriging interpolation methods. © 2020 Parlar Scientific Publications.
