A Preliminary Study on the Effect of Different Phosphorus Levels on the Yield and Some Yield Components of Horse Bean (Vicia faba var. minor) Grown under Shade and Open Conditions

2024-09-20T13:35:15+03:00

The experiment was carried out during 2022-23 winter seasons to find out the effect of phosphorus levels on the grain yield and yield components of horse bean (Vicia faba var. minor) grown under shade and open conditions. Six different levels of phosphorus (0, 30, 60, 90, 120 and 150 kg P₂O₅ ha^-1) were tested on the crops, and, some properties were measured such as plant height, number of pod per plant, thousand grain weight, yields of biological and grain in the research experiment. Growing condition (media) and rate of phosphorus had a significant effect on all of the measured traits of horse bean. Crops grown at open condition produced higher grain yield compared to shade and was significantly superior. Increasing rates of P increased the yield and yield components of horse bean compared to the control (P0). Among different P levels the highest biological and grain yield were recorded with the application of 90 kg P₂O₅ ha^-1 for horse bean grown under open condition.

Influence of Nickel on Urease Activity and Nitrogen Dynamics in Maize (Zea mays) Under Saline Conditions

2024-10-21T15:48:13+03:00

Nickel (Ni) is a vital micronutrient that significantly contributes to essential plant functions, including normal growth, enzymatic activities, and nitrogen metabolism. Soil urease activity can markedly decrease under saline conditions, and both plants and soil organisms necessitate Ni for the effective assimilation of urea. This study investigates the effects of varying levels of Ni supplementation (0, 25, 50, and 100 mg kg^-1) under saline soil conditions on soil and plant urease activity, biomass yield, chlorophyll content, nitrogen (N) content, and nitrate assimilation. Thermal imaging was employed to assess plant stress by measuring leaf temperature. Results showed that the 25 mg kg^-1 Ni treatment notably improved soil urease activity, leading to enhanced nitrogen uptake and biomass production. This Ni dose also resulted in the lowest leaf temperature in maize, indicating reduced stress. Low Ni levels increased nitrate reductase (NR) activity, nitrate content, and free amino acids in maize, while sharply reducing ammonium accumulation, suggesting that Ni promotes plant growth by regulating nitrogen assimilation. However, the 100 mg kg^-1 dose caused toxicity in maize. All Ni concentrations decreased plant urease activity, indicating decreased urea uptake from the soil. Overall, these findings suggest that low doses of Ni support nitrogen metabolism and plant performance by regulating urease activity in both soil and plants, while higher doses have toxic effects.

Assessment of Cardıac Hypertrophy ın Natıonal Race Horses by Ecocardıography

2024-11-12T12:03:03+03:00

Since there is no sufficient data regarding the development of the heart and maximal frequency running speed in national racehorses, the morphological and physiological capacity of the heart can be easily measured non-invasively by echocardiography. The main goal in selecting a racehorse is to select one that will show above-average athletic potential in its future racing life. The horses participating in our study were healthy and of different genders. The horses were examined in their shelters using an Esaote AU5 brand Color Doppler echocardiography device with a 10 mHz probe. Standard echocardiographic evaluation of horses was performed using two-dimensional (2D) mode, M-mode and Doppler echocardiography methods from 5 different windows, parasternal and apical. Detailed echocardiography was performed on the left and right chest of the horses included in the study. In the study, reference ranges of end-diastolic diameter, end-systolic diameter, interventricular septum (IVS) diastolic and end-systolic thicknesses, and posterior wall diastolic and end-systolic thickness diameters were established. Fractional shortening, ejection fraction, heart rate and ventricular masses were measured. Echocardiography showed that the horses' heart muscles were hypertrophic. Thickening was observed in the interventricular septum and posterior walls. In order to determine the athletic potential of national racehorses, field-oriented, non-invasive tests that do not disrupt the trainer's work routine are needed. One of these tests is the data obtained using the echocardiography technique on the morphological and physiological capacities of the heart in horses.

Determination of Heart Tumor Foci in Pets and Clinical Results

2024-11-12T10:37:52+03:00

To evaluate echogenic increases in the heart chambers (cardiac tumor-myxoma) in domestic animals with echocardiography and to share the results. Different images were obtained from dogs and cats that came to veterinary clinics between 2001 and 2024 for echocardiography. For the echocardiography study, a cat-dog cardiac probe was used and the images were recorded with a color printer device. In cardiac studies, especially in dogs, most intracardiac echogenic foci were unilateral, but bilateral echogenic increases were observed. Although the left atrium was the most common location, rare images were observed in the right atrium. The origin of the tumor was determined on echocardiography and medical treatment was given first. The patient's relatives were told that if medical treatment did not respond, the tumor would have to be removed. Some of our patients with cat and dog cardiac tumors responded to treatment. Our dog, who had left and right atrium biatrial myxoma, seemed to be fine with medical treatment at first, but later died in a short time. Two cats with left atrial myxoma died after one year. Our cats and dogs, which are still being followed, are prolonging their lives as their other cardiac problems respond to treatment.

2024-10-28T20:52:16+03:00

The aim of this study was to determine how different tillage systems and herbicide application impact weed density and grain yield in the double crop maize (Zea mays L.) agriculture after barley. For this purpose, a two-years field trial was carried out in the experemental areas at Agriculture Faculty, Dicle University, Diyarbakır, Turkiye in the 2022-23 growing season, comparing different soil tillage methods [conventional tillage (mouldboard plough+cultivator), reduced tillage (disc harrow) and no-tillage] and herbicide applications [pre-emergence, post-emergence, pre-emergence + post-emergence, weed-free control, weedy control]. In the experiments carried out with three replications according to the split plot design in randomized blocks, the main plots were composed of soil tillage methods and the sub-plots were composed of herbicide applications. The results of the study indicated that while different soil tillage methods had no effect on both weed density and the grain yield, herbicide applications significantly affected them. Both pre-emergence and post-emergence herbicide application significantly reduced the weed density and biomass.

2024-11-11T15:32:51+03:00

Hawthorn fruit (Crataegus spp.) has a broad ethnobotanical history and traditional use, primarily recognized for its heart health-supporting properties. Throughout history, it has been widely utilized in various cultures’ folk medicine to regulate heart rhythm, improve blood circulation, alleviate digestive issues, and strengthen the immune system. Modern scientific studies further validate these traditional uses by confirming that hawthorn’s bioactive compounds, including flavonoids, phenolic compounds, triterpenoids, and proanthocyanidin, provide potent antioxidant, anti-inflammatory, and cardiovascular-supporting benefits. Consequently, hawthorn fruit holds significant potential as a natural ingredient in functional foods and health products. Hawthorn fruit is particularly valued for its ethnobotanical importance worldwide and especially in Turkey. In many Turkish regions, it is employed for its ability to lower high blood pressure, soothe digestive problems, enhance blood circulation, and provide a calming effect. In Anatolian culture, hawthorn is regarded not only as a food but also as a source of health. Its contributions to heart health, immune system enhancement, and metabolic balance are particularly emphasized. This study examines the antioxidant properties of hawthorn fruit, its effects on reducing oxidative stress, and its cell health-supporting attributes, with an evaluation of its potential as a natural component in modern health products and functional foods. However, further research is required to thoroughly understand the beneficial effects of hawthorn fruit on health. Specifically, determining safe and effective dosage ranges, elucidating its biochemical effects, and exploring its potential role in serious conditions like cancer are of paramount importance. Hawthorn can be consumed in forms such as tea and capsules to support cardiovascular health, while dried fruit or jam offers a natural antioxidant boost. Traditional forms like molasses, vinegar, and marmalade are also recommended as part of a health-supportive diet for immune system benefits.

Investigation of Hemocyte Types in Lepisma saccharina

2024-11-14T00:55:30+03:00

Hemocytes are specialized hemolymph cells found in insects, responsible for a variety of important physiological functions such as immunity, wound healing, and the regulation of the insect's circulatory system. The study of insect hemocytes has become increasingly important in recent years due to the emergence of insect-borne diseases and the need to develop new strategies for insect control. Understanding the biology of insect hemocytes has the potential to lead to the development of novel insecticides and strategies for controlling insect-borne diseases. The aim of this study was to examine the hemocytes in Lepisma saccharina to determine if there were any variations in the types of hemocytes present among ametabolous and holometabolous insect or in comparison to other arthropods. Hemolymph of L. saccharina collected and hemolymph smears were stained with Wright’s stain. In adult L. saccharina two hemocyte types, prohemocyte and plasmatocyte were observed. The hemocyte types were identified based on their size, presence or absence of granules, and the ratio of their nucleus to cytoplasm, using light microscopy.

2024-11-24T02:57:29+03:00

G×E interaction is critical for understanding how genetic and environmental factors affect plant performance, and this interaction is essential for developing more efficient and adaptive genotypes in plant breeding. In study, The GGE biplot analysis played a crucial role in determining effects on the yield performance of genotype × environment (G×E) interactions and comparing the stability and adaptability of genotypes in Diyarbakir and Kiziltepe. Additionally, cluster analysis was performed using the Ward method, which grouped the genotypes based on yield similarities and identified distinct groups adapted to different environmental conditions. The experiments were arranged by the factorial experimental design with four replications in each environment during the summer seasons of 2015 and 2016.Consequently, the significant differences were determined between genotypes and locations and their interactions. GGE biplot analysis found that the variations in the yield performance of genotypes were caused by 81.24% by the first principal component (PC1) and 18.76% by the second principal component (PC2). FLIP98-206C and FLIP98-143C genotypes were shown high yield potential and stability. In contrast, genotypes D1-3 and Azkan exhibited lower stability and yield performance. Therefore, the high-yielding and broadly adapted genotypes must be prioritized for experiments in regions Diyarbakir and Kiziltepe. However, narrower target regions must be identified for low-performing genotypes and large-scale experiments in these regions should be conducted to understand the long-term yield and stability performance of high-yielding genotypes.

2024-11-29T03:17:15+03:00

This study focused on the significance of weed control in organic chickpea (Cicer arietinum L.) cultivation and the effectiveness of alternative weed control methods. The environmental impacts of herbicide use and the development of resistance in weeds, which are among the chemical control methods, necessitate the improvement of alternative weed control methods for sustainable agricultural practices. In this study, the effectiveness of different methods, such as organic source materials, biological control agents, mechanical hoeing and other cultural practices on weed control was evaluated. The research was carried out in the area reserved for organic cultivation in the field crops application and research area of Dicle University Faculty of Agriculture, Faculty of Agriculture in the 2021 growing season. The experiment was set up according to the Randomized Block Design with 3 replications and Arda chickpea was used. Weedless control, weedy control, hand plucking before flowering, hoeing before flowering, hand plucking at pod stage, hand plucking at pod stage, hand plucking before flowering + pod stage, sowing with 20 cm spacing, sowing with 45 cm spacing, whey, whey + hoeing, pickle juice and pickle juice + hoeing were applied as weed control. Plant height, fresh weight, total number of pods, total pod weight, number of full pods, number of empty pods and number of grains per plant were investigated. Consequently, mechanical practices such as hoeing and manual weed control have reduced weed pressure and increased plant yield. Hoeing treatment increased the number of full pods by 28%, grain weight by 35%, and manual weed control reduced weed pressure by 20% and increased yield by 25% compared to other treatments. In the treatment without weed control, a 40% loss in yield was observed. By comparing different control methods in the research, it will contribute to the determination of sustainable weed management strategies and increase agricultural productivity. Furthermore, different control methods should be investigated in order to develop sustainable weed management strategies.

Mapping Environmental Noise from Road Transportation Using SoundPLAN: The Case of Harran University Osmanbey Campus

2024-12-03T12:16:59+03:00

Noise pollution is a critical environmental problem that negatively affects human health and quality of life. It is particularly significant in educational environments, where excessive noise can impair students’ learning abilities, concentration, and overall academic performance. This study evaluates noise pollution on the Osmanbey Campus of Harran University, with a specific focus on traffic-related noise levels. Measurements were conducted at 11 key points during the Ld (07:00–19:00), Le (19:00–23:00), and Ln (23:00–07:00) periods. The SoundPlan 7.4 model was used to generate noise maps and analyze the distribution of environmental noise across the campus. Road traffic was identified as the main source of noise, especially in areas with high vehicle density, such as intersections and bus stops. The results determined that noise levels on campus exceeded the thresholds established by the WHO across all periods. The highest noise level was recorded at Point 2 during the day (74.90 dBA), a busy area with frequent bus activity and human movement. The lowest level, measured at Point 5 during the night (56.40 dBA), was in a quieter area near the Faculty of Sports Sciences but still slightly above the recommended nighttime limits. These findings underscore the importance of addressing noise pollution, particularly in educational settings, to support a conducive learning environment. Suggested mitigation strategies include traffic management, acoustic landscaping, and continuous noise monitoring. Additionally, promoting sustainable transportation options, such as cycling can contribute to reducing noise levels and fostering a healthier campus atmosphere.

Devices Used in Measurement of Moisture Values in Wooden Elements and a New Device Proposal

2024-11-18T15:11:47+03:00

The relationship of wooden elements with humidity is of economic and technical importance. This is because the important structural behaviour of timber elements, especially their processing properties and mechanical behaviour, changes with the change in moisture content. The determination of the amount of moisture in a wood material is now carried out with electric moisture meters in addition to the drying methods used in the past. This type of devices used in wood moisture measurement are generally imported from abroad, but they have only limited features due to their physical and technical structure deficiencies. In addition, they have high costs as they are purchased from abroad in foreign currency. It has been preferred to install the moisture measurement in wood on the Arduino system, which is frequently preferred in automation system designs and is also suitable for the production of economic solutions. The moisture measurement values obtained from different types of woods with the device we have created are compared with the moisture measurement values of the devices available in the market and shown on graphs

Effects of Different Doses of Biochar and Zinc Phosphate Applications on the Development of Canola Plants

2024-12-10T22:21:43+03:00

In agriculture, many organic compounds are used as organic fertilizers to maintain plant production. Biochar organic soil amendments are commonly recommended for improving problematic soils due to their environmental friendliness, efficiency, and economic viability. In this experiment, canola (rapeseed) was used as the plant material. Zinc phosphate and cotton stalk biochar at different doses were used as nutrient sources. The study was conducted using a randomized block design with 3 replications, and plastic pots were used. All treatments were applied along with the planting process. In the control group, no treatment was applied, while in the second treatment, only 0.8 g of zinc phosphate was added to the soil, and the soil was mixed thoroughly. In other treatments, cotton stalk biochar was applied along with 0.8 g of zinc phosphate in the following doses: 1.2 g/pot, 2.4 g pot^-1, and 3.6 g pot^-1. The results showed that the application of zinc phosphate and zinc phosphate + biochar increased the canola plant yield in relation to increasing doses. Specifically, with 0.8 g zinc phosphate, the increase was 6.40%, with 0.8 g zinc phosphate + 1.2 g biochar it was 14.57%, with 0.8 g zinc phosphate + 2.4 g biochar it was 20.21%, and with 0.8 g zinc phosphate + 3.6 g biochar, the increase reached 25.75%. The highest increase was observed with the application of 0.8 g zinc phosphate + 3.6 g biochar, while the lowest increase was observed with 0.8 g zinc phosphate. The study demonstrated that the application of biochar positively contributed to the plant parameters.

Digital Mapping of Soil pH and Electrical Conductivity: A Comparative Analysis of Kriging and Machine Learning Approaches

2024-12-13T07:45:52+03:00

Soil pH and electrical conductivity (EC) are critical soil properties influencing agricultural productivity and environmental sustainability. This study evaluates the performance of stacked machine learning models in predicting and mapping soil pH and EC values. Base models such as Ordinary Kriging (OK), Universal Kriging (UK), and Disjunctive Kriging (DK) were employed, and their outputs were integrated into a Multilayer Perceptron (MLP) neural network meta-model. The results reveal the superior performance of the MLP meta-model across all metrics. For instance, in predicting pH, the MLP model achieved an RMSE of 0.028, an MAE of 0.020, and an R²of 0.858 on the training dataset. For EC predictions, the MLP model outperformed others on the test dataset, with an RMSE of 0.039, an MAE of 0.028, and an R² of 0.900. In contrast, the UK and DK methods exhibited lower accuracy, particularly on test datasets. This study shows the advantage of modern machine learning algorithms in modeling nonlinear spatial relationships and their significant potential in digital soil mapping. The findings demonstrate the applicability of these approaches in enhancing agricultural productivity and supporting sustainable soil management practices.

Determination of Natural Radiation Amount in Apricots Growing Up in Malatya

2024-12-23T09:43:35+03:00

The aim of this study is to determine the radioactivity concentrations of dried apricot samples collected from six different districts within the borders of Malatya province. Peaks originating from the radionuclides of ⁴⁰K and the natural series of ²³⁸U (²²⁶Ra) and ²³²Th were identified in the gamma spectra obtained using a NaI scintillation detector. The activity concentrations corresponding to these peaks were found to range between 493±23 and 629±30 Bq kg^-1 for ⁴⁰K, 4.3±0.6 and 18.5±2.2 Bq kg^-1 for ²³⁸U, and 0.6±0.1 and 4.3±0.3 Bq kg^-1 for ²³²Th. The average values were calculated as 570±27 Bq kg^-1 for ⁴⁰K, 10.4±1.2 Bq kg^-1 for ²³⁸U, and 2.6±0.2 Bq kg^-1 for ²³²Th. While the measured values for the ⁴⁰K radionuclide exceed 400 Bq kg^-1, they are within acceptable limits. It does not pose a risk to human health. It is evaluated that the use of potassium-containing artificial fertilizers to supplement the mineral content of apricot trees is the cause of this.

2024-11-15T23:51:24+03:00

Modeling and analyzing lifespan data is essential in many application areas, including medicine, engineering, and finance. These types of data have been modeled using various lifetime distributions. The assumed probability model(s) have a significant impact on the efficiency of the procedures used in statistical research.Forthisreason, much work has been devotedtoderivingalargeclass of normal probability distributions andrelated statistical techniques. However,real-worlddatachallenge all established probability models, leaving manyimportant issues unresolved.This present work add another novel distribution with two parameter called two-parameter betaexponential distribution (TPBED), including the beta (2,b)distribution and the new XLindley distribution as special cases. We provide a complete mathematical treatment of this distribution. We derive the moment generating function and the r-th moment, thereby generalizing some results from the literature. Expressions for the density, moment generating function, entropy and the r-th moment of the order statisticare also obtained. We observe in three applications to simulated and real data sets(demography and geostandards) that this model is quite flexible and can be used quite effectively for analyzing active data in place of one and two-parameter distributions such asthe exponential, Lindley, XLindley, new XLindley, Xgamma, Zeghdoudi, Chen, Lindley gamma, quasi-new Lindley, two-parameter Lindley, Power XLindley, and Gamma.

Determination of Nurses' Site Preference and Reasons For Intramuscular Injection in Gluteal Region: A Descriptive, Cross-Sectional Study

2024-12-24T12:08:12+03:00

Studies show that the ventrogluteal site is safer for intramuscular injection in the gluteal region, but nurses prefer this site less. The aim of this study was to determine the preferred site in the gluteal region for intramuscular injection and the reasons for preference. This descriptive and cross-sectional study was conducted in a University hospital. The study's sample consisted of 130 nurses. The data were collected with a questionnaire form and evaluated using number, percentage, mean, and standard deviation calculations. It was determined that 62.3% of the nurses preferred to use the dorsogluteal site, 5.4% to use the ventrogluteal site, and 32.3% to use both sites for intramuscular injection. The reasons for the nurses' preference for the dorsogluteal site were determined as a habit, mandatory position, obesity, patient's desire, cachexia, being a safe site, ease of application, and receiving training only on this site. The reasons for choosing the ventrogluteal site were determined as patient desire, obesity, forced position, more reliability, habit, cachexia, less risky, and less painful, respectively.

Novel One Parameter Family:Special Case, Bayesian Estimation, Simulation and Applications

2024-10-17T16:44:38+03:00

This paper introduces a new one-parameter family (NPFD) derived from the cumulative distribution function (CDF). We study the main properties of the proposed family, with a special emphasis on its moments, reliability parameters, and asymptotic distributions of the extreme order statistics. Then, inferential considerations are explored. We discuss the parameter estimation by the moments, maximum likelihood methods and the Bayesian estimation. Also, likelihood estimation and Bayesian estimation using the Pitman asymptotic criterion are given. Three applications reveal that the new model can fit well practical data sets.
