Izuwa Iwanegbe | K.O. Durojaiye
The study produced milk drink that is high in protein and energy from soy beans and tiger nuts blends as well as to assess the beverage qualitatively and customer acceptability using response surface methodology (RSM). The principal raw materials used were soybeans and tiger nut. They were processed into milk at different formulations without using chemical preservative. Sensory evaluation, pH, titratable acidity as well as proximate and mineral compositions were determined. The results showed that the minimum and maximum colour score varied from 4.4 to 5.0. The quadratic model for colour was found to be significant (p<0.05) in tiger nut inclusion. The model equation obtained for colour = 4.50 + 0.048*A + 0.098*B + 0.019*A2 + 0.12*B2 + 0.18*A*B where A = Soybeans, B = Tiger nut. Mouth feel model’s F-value of 7.35 indicates that it was significant (p<0.05). Model terms are considered important when the “Probability > F” value was less than 0.05. The model for quadratic equation for mouth feel was 7.290. +5.00 -0.091*A -0.19*B -0.14* A2 -0.44* B2 +0.45* A*B. The model for the quadratic equation for Taste = +3.90 +0.030*A +0.020* B +0.21*A2 +0.056*B2 +0.075*A*B adequate precision = 3.65, corrected R2 = 0.29, R2 = 0.59 and the predicted R2 = -1.94. It was observed the pH values decreases with storage days from day 0 to day 8 for samples A, I and Z. On day 12, the pH values increased for all the samples except for sample M. The Titratable acid increased as the pH decreased. On the 0 day, sample A had value of 20.8 while sample M was 23.33. However, sample I increased from 0, 4, 8 and 12 days (20.19, 20.20, 22.47 and 23.73) respectively. Sample M had the highest protein content (3.52%), followed by sample A (3.21%), sample I (3.01%) and sample Z (2.02%). Sample Z had the lowest fiber content (0.30%), next was sample I (O.43 %), sample A (0.51%), and sample M (0.54%). The range of moisture contents was 81.03 to 82.04%. Conclusively, optimizing soybeans at 100g/ml with 40 g/ml of tiger nut could help to improve the sensory attributes such as colour, taste, mouth feel, flavor and overall acceptance. The formulation could influence shelf stability of product, bridge protein in-balance and reduction in malnutrition level.

Sakuna Nepal | Pratibha Khatiwada | Pankaj Karki Dholi | Safal Adhikari
Promoting rooftop farming using suitable grow bag media is of utmost importance in densely populated cities like Lalitpur to sustain the human race. To assess the productivity and other economic characteristics of bell peppers, an experiment was conducted from Feb 2022 to Jun 2022 in different grow bag media on the premises of Vegetable Crop Development Centre, Khumaltar, Lalitpur. The experiment was conducted in Randomized Complete Block Design (RCBD), with four replications and five treatments with growing media: Coco peat: vermicompost (1:1), Soil: sand: FYM (Farmyard Manure) (1:1:1), Soil: Sand: FYM: Vermicompost (1.25:0.75:0.5:0.5), Soil: vermicompost (1:1), and Soil: ash: FYM (1:0.5:1) on the cultivar California Wonder. Growth parameters like plant height (47.865 cm), number of leaves (50.6), number of branches/plant (9.5), and stem diameter, and yield parameters like total fruit weight (1693.93 gm), average fruit weight (84.68 gm), number of fruits (42.75), fruit diameter (6.37 cm), and fruit length (7.22 cm) were observed during the experiment. The media consisting of T3 (Soil: Sand: FYM: Vermicompost (1.25:0.75:0.5:0.5)) proved to be statistically superior over the rest of the combinations for almost all aspects under investigation, whereas comparatively poor performance was observed in Coco peat: vermicompost (1:1) media. This study suggests that the grow bag media of Soil: Sand: FYM: vermicompost (1.25:0.75:0.5:0.5) gave the highest gross return and net return, with the highest B: C ratio (2.08) observed in the grow bag media of Soil: Sand: FYM (1:1:1).

The objective of this study was to evaluate the effects of palm oil, African walnut oil and their blends on hematological, inflammatory, and some oxidative stress markers in high fat diet (HFD) obese-induced Wistar rats. Obesity was induced for 60 days and treated for 28 days using edible oils [palm oil, African walnut oil, palm oil: African walnut oil (50:50) and palm oil : African walnut oil (60:40)] and orlistat (10 mg/Kg). Thereafter the animals were sacrificed, blood was collected for hematological studies and the preparation of the serum, while the organs harvested were used to prepare organ homogenates. Serum and organ homogenates were used for the evaluation of inflammation and oxidative stress markers. Results showed that the oils utilized were confirmed to be of high quality through their good stability indices (peroxide value: 2.52-3.87meq O2/Kg; p-anisidine value: 8.24-12.33, TOTOX value: 13.37-19.46,). Looking at the haematological study, animals that received the HFD presented the lowest (p<0.05) hematocrit and Platelet. PO:WO (50:50 and 60:40) significantly (p<0.05) decreased the granulocytes concentration in the blood of rats. PO:WO (50:50) significantly (p<0.05) increased the lymphocyte concentration while 100% PO increased the mid-size white blood cells level in the animals. Serum levels of inflammation markers were higher (p<0.05) in the negative control group (354.44-385.82 pg/mL) compared to the other groups (147.22-271.55 pg/mL). The analysis of oxidative stress parameters revealed that the administered oils and orlistat generally exhibited good protections compared to the normal and negative control groups, which might be due to the presence of omega-3 fatty acids and bioactives such as β-carotene and vitamin E which have good antioxidant and anti-inflammatory properties. It can be concluded that these oils have a role in protecting against obesity through their effects on oxidative stress, hematology, and inflammatory cytokines.

Developments in Geographic Information Systems and Remote Sensing (RS) technologies and innovative approaches emerging in deep learning (DL) supported analysis methods have an important place in disaster research as in every field. Convolutional neural networks such as Mask RCNN, U-NET, one of the deep learning methods for disaster damage impact assessment and classification, have started to show successful results. However, high-resolution geospatial imagery and drones provide faster and more accurate detection of structural damage. In this study, damaged building detection was performed using Göktürk-1 satellite images from 6 February 2023 using Mask-RCNN architecture. In this study, deep learning methods were used to detect the collapsed buildings in the city of Malatya during the 6 February 2023 earthquakes. The study aims to emphasize the significance of GIS and remote sensing for the timely and efficient evaluation of building damage after a disaster. Considering this, high quality images of Malatya city before and after the earthquake were analyzed and data sets were created by masking using Mask RCNN deep learning method through ArcGIS Pro 3.4.0 software. According to the results of the research, it quickly detected damaged buildings with an accuracy rate of 70% according to satellite images after the earthquake. As a result, GIS and deep learning models were used to detect and map the initial damage after the earthquake.
Afficher plus [+] Moins [-]The Impact of PEG-induced Drought Stress on Seed Germination and Initial Seedling Growth of Lupinus albus L. Texte intégral

Ramazan Beyaz | Veli Vural Uslu
Drought is regarded as one of the most significant abiotic constraints to agricultural crop output worldwide. Drought in the spring and early summer, which coincides with important reproductive stages, severely limits lupin yield in Mediterranean climate zones. The purpose of this study was to determine how different drought treatments affected seed germination and initial seedling growth in Lupinus albus L. (white or field lupin). Seed germination parameters and initial seedling growth traits were tested against five levels of drought stress induced with Polyethylene glycol-6000 (PEG6000) at concentrations of 0, 4, 8, 12, and 16%. An experiment with four replications was conducted using a completely randomized design. The results revealed that the negative effect of drought stress started at 4% (-0.03 MPa or -0.3 bar) treatment for the initial seedling growth stage; whereas, it started at 12% (-0.2 MPa or -2 bar) treatment for the germination stage. Therefore, it was determined that L. albus was more sensitive to drought stress at the initial seedling growth stage than at the germination stage. However, it was observed that the growth parameters were more sensitive in shoot growth than in root growth to drought stress. There will be a sharp loss of yield in soils with levels of drought stress imposed by 12% PEG6000 (-0.2 MPa-moderate drought-) and beyond. Therefore, it is likely that L. albus has low drought tolerance.

Okra (Abelmoschus esculentus) cultivation in regions like Ramechhap, Bagmati Province, Nepal faces challenges in improving yield and economic returns due to suboptimal agronomic practices. To address this issue, a field experiment was conducted to assess the effects of pinching and micronutrient sprays (zinc and boron) on growth, yield, and economic returns of okra. The study aimed to evaluate the impact of pinching and zinc-boron foliar application on key growth parameters, including the number of leaves, fruit length, number of fruits per plant, and total yield. Pinching significantly increased the number of leaves and fruits per plant, as well as the total yield. The application of 0.25% Zn + 0.25% B resulted in the highest fruit length, fruit weight, and total yield. The combined treatment of pinching and Zn-B spray (P1M3) recorded the highest fruit length (11.13 cm), number of fruits per plant (21.91), and yield (17.68 t ha-1). Economic analysis revealed that this combination resulted in the highest net return (NRs. 774,869.35 ha-1) and the highest benefit-cost ratio (B:C = 1.95), indicating that it could significantly improve farm income for smallholder farmers in the region. These results demonstrate the potential of integrated agronomic practices, including pinching and micronutrient application, to enhance both productivity and profitability in okra cultivation.

2025
Simge Doğan | Levent Genç | Sait Can Yücebaş | Metin Uşaklı
Agricultural lands are known not only as agricultural production areas but also as areas with high income expectations as an investment tool. In Turkey, recent fluctuations in economic indicators such as the euro, dollar, and gold, along with increasing investment demand, have caused agricultural land prices to rise uncontrollably. Controlling land price increases is important for preventing the misuse of agricultural lands. The sustainable management of agricultural lands and price stability are closely related to the United Nations Sustainable Development Goals (SDGs), particularly SDG 11 and 15, “Sustainable Cities and Communities” and “Life on Land.” In this context, accurately predicting prices is important for minimizing price fluctuations in agricultural lands for investors and landowners and supporting sustainable development. In general, the Multiple Linear Regression (MLR) model is considered one of the effective traditional methods for predicting real estate prices. However, depending on the data, more reliable results can be obtained than with powerful deep learning models such as the Extreme Gradient Boosting (XGBoost) algorithm, which exhibits superior prediction performance. This study aims to compare the MLR and XGBoost algorithms to predict agricultural land prices in villages located in the central district of Çanakkale and to examine daily fluctuations in economic indicators such as the dollar, gold, and euro. The results showed that XGBoost (R2 = 0.66) has an advantage in terms of coefficient of determination values compared to MLR (R2 = 0.01). Accurate price prediction for agricultural lands will help control fluctuations in land prices. Additionally, it will support farmers and investors in making informed decisions for a sustainable agricultural economy.

The existing practice of using excessive mineral fertilizers for maize production not only degrades the soil quality but also poses a threat to the overall ecosystem. Thus, in our research, we attempt to investigate the influence of biofertilizers on yield and yield attributing traits of maize, as a better, alternative, cheaper, eco-friendly, and sustainable solution. A two-factorial field experiment (RCBD) was carried out in Gaindakot, Ward No. 8, Nawalpur district, to assess the effect of Azotobacter in association with other fertilizers on the growth and yield of different maize varieties. The experiment consisted of 15 treatments (3 maize varieties and 5 different nutrient sources) with 3 replications. The three maize varieties used were Local Pahelo, Rampur Composite, and Rampur Hybrid-14, while the nutrient sources included Control, Farmyard Manure (FYM) only, Azotobacter-inoculated seeds, Azotobacter + FYM, and Azotobacter + chemical fertilizers (NPK). The results obtained revealed that the optimum performance was observed in Rampur Hybrid-14 with the nutrient source being Azotobacter inoculation in combination with FYM, resulting in a Leaf Area Index (LAI) of 0.39, 15 leaves, a grain yield of 8.41 tons per hectare, dry stover weight of 0.964 kg per meter square and a root length of 32.33 cm. The results demonstrated that the use of Azotobacter in combination with FYM in the Rampur Hybrid-14 variety could result in higher yields in commercial maize production, reducing the need for excessive mineral fertilizers.

In this study, it was aimed to examine the potential therapeutic effects of Urtica dioica seed (UDS) oil on hepatorenal damage induced by methotrexate in rats. Thirty-two Wistar albino rats were divided into four groups: Control, Methotrexate (MTX, 20 mg/kg i.p.), UDS (30 ml/kg feed containing UDS), and MTX+UDS (20 mg/kg i.p. + 30 ml/kg feed containing UDS oil, respectively). At the end of the six-week study, the MTX-treated group demonstrated elevated levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) in serum and increased levels of malondialdehyde (MDA), an indicator of lipid peroxidation in liver, kidney, and blood tissues. However, reduced glutathione (GSH) levels (apart from erythrocytes) showed a significant decrease (p<0.005). The MTX group's liver and erythrocyte tissues showed a significant decrease in glutathione reductase (GR) activity compared to the control. Additionally, there was a significant decrease in the activities of glutathione peroxidase (GPx) and catalase (CAT) in the MTX group as compared to the control. The co-administration of MTX+UDS decreased liver MDA concentration and the levels of the enzymes AST, ALT, and LDH compared to the MTX group. On the other hand, there was an increase in kidney glutathione S-transferase (GST) activity and GSH levels. Histopathological investigation revealed that pellets containing UDS oil significantly reduced the degenerative and necrotic changes that MTX had generated in the liver and kidney, including parenchymal and hydropic degeneration and inflammatory cell infiltration. Immunohistochemical staining showed that caspase 3, a marker of apoptosis, decreased significantly with the administration of UDS oil. In conclusion, MTX-induced hepatorenal damage was either prevented or greatly decreased by UDS oil.
