In today's growing economy, consumer demand for rice is evolving, with a preference for high-quality varieties that are soft and aromatic when cooked. We conducted a study to identify high-quality rice varieties that meet these consumer preferences. Molecular markers were used to find genes linked to desirable traits in rice. These genes are DRR-GL for grain length (gene GS3), Wxin1 for amylose content (gene Wx), and BADH2 for aroma. The findings revealed that the molecular marker DRR-GL, used with primers EFP, IRSP, ERP, and IFLP, accounted for 90% of the expression of the long-grain phenotype. Similarly, the Wxin1 marker, with primers GF, TR, GR, and TF, explained 90% of the variation in amylose content. The BADH2 marker, using primers ESP and IFAP, INSP, and EAP, accounted for 100% of the aroma phenotype expression across all tested varieties. Among the 20 traditional rice varieties examined, the variety Nep Trong Vo exhibited superior qualities, including an elongated grain length of 7.13 mm, an average amylose content of 17.58%, a soft gel consistency graded at 3, and high heat resistance also graded at 3. These characteristics make Nep Trong Vo a promising candidate for meeting the high-quality standards demanded by consumers.

The study was carried out to evaluate the resistance of various domestic citrus species to the root lesion nematode Pratylenchus sp. for further research in rootstock selection as well as nematode management. The experiment was accomplished in a completely randomized design with 19 popular citrus species as 19 treatments, with thirty repeats and one plant for each experimental unit. The population of the nematode after 15 days of inoculation was calculated from growing media and roots for classifying the resistance capability of Citrus species. As a result, referred to the statistical analysis results and the Reproductive Index of the target nematode, they were suggestively classified into 5 distinctive groups: (i) resistant species: C. grandis var. Duong La Cam, C. maxima var. Tam Quy, L. littoralis, C. nobilis var. typica; (ii) moderately resistant specie: C. nobilis var. Sanh; (iii) moderately susceptible species: C. latifolia, C. macroptera, C. sinensis cv. Soan, C. microcarpa , and C. reticulata var. Duong; (iv) susceptible species: C. maxima var. Da Xanh, C. maxima var. Long Co Co, C. maxima var. Nam Roi, C. sinensis var. Mat, and C. nobilis var. chrysocarpa; (v) highly susceptible species: C. limonia, C. hystrix,  C. volkameriana and P. trifoliatus. Therefore, C. grandis var. Duong La Cam, C. maxima var. Tam Quy, L. littoralis, and C. nobilis var. typica could be further researched to select appropriate rootstocks for citrus cultivation in the nematode-infected regions.

This study utilized a range of machine learning algorithms to predict the hourly streamflow in the Ikpoba River. Data gathering relied on a Hydromet System installed along the river, collecting hourly measurements of gage height, ambient temperature, and atmospheric pressure. To convert the gage height to streamflow data, historical gage and streamflow data covering the period from 2015 to 2020 were extracted from the Ikpoba River rating curve and were analyzed using curve fitting techniques to establish the precise relationship between streamflow and gage height. Various goodness-of-fit measures, such as adjusted R-squared value, standard error of estimate, and coefficient of determination, were utilized to identify the best-fit relationship. The estimated streamflow data were subsequently validated using the Soil and Water Assessment Tool, incorporating the digital elevation model of the study area, along with other input parameters like soil, slope, daily maximum precipitation, and daily maximum temperature. Validation results were illustrated using regression plots generated in Microsoft Excel. From the machine learning results, random forest algorithm outperformed other methods in predicting streamflow, with a mean square error of 0.02 and a coefficient of determination of 0.98. Conversely, decision trees showed superior accuracy in predicting individual data points, with the lowest root-mean-square error of 0.02.

Computer vision is considered a useful tool for evaluating the external quality of fruits. Some solutions for capturing the entire surface image of fruits have been implemented, but they still have limitations, such as not being able to guarantee capturing the entire surface, bulky, or expensive. In this study, a two-shot and simple system for capturing the entire surface image of fruits was proposed. With the support of a mirror system, the top and lateral surfaces of the fruits were captured. To capture the bottom surface of the fruits, a flip mechanism has been integrated into the system. Testing results with pomelo and mango showed that the entire surface of the fruits was fully observed with two shots. This shows that the proposed system has great potential for imaging the entire surface of fruits. Besides, this solution can also be easily integrated into automatic inspection applications to evaluate the quality of agricultural and other products.

Globally, there is growing concern about the transfer of heavy metals into human food and water due to their ability to move from soil to plants. This study evaluated the health risks associated with the transfer of heavy metals from soil to Celosia trigyna and Amaranthus viridis along the Lekki Peninsula in Lagos. Soil and vegetable samples were collected from 12 locations, and the levels of heavy metals in the samples were determined using an Atomic Absorption Spectrophotometer. Soil pH was slightly acidic (5.31 –6.82). EC values range from 121 to 382µs/cm, while low soil CEC, N, TOC and OM were recorded in all the study sites. The concentrations of heavy metals in the soils were in this order: Zn >Cu>Mn >Cd>Pb. The uptake of metals by the vegetables was in the order Cu>Zn>Mn>Cd>Pb. Estimated Daily Intake (EDI) from Consumption of C. trigyna and A. viridis ranged between 0.1320-0.000mg-1kg-1adult-1d-1. The Health Risk Index ranged from 5.23 to 0.01. The total Hazard Index was 41.75. The concentration of heavy metals in the vegetables was a function of contaminated soil and toxic elements deposition from passing vehicles. Following the hazard index result, the vegetables in locations 1 – 6 are not safe for human consumption.

This study aimed to evaluate the effectiveness of different conditions (i.e., different salt concentrations from 3.5 to 4.5%, and initial Lactobacillus plantarum populations from 104 to 106 CFU/mL) on the quality of fermentative grey oyster mushrooms at 15oC during 25 days. The quality parameters i.e., total color difference, texture, total soluble solid, pH, lactic acid bacteria counts, total polyphenol content (TPC) and the free radical scavenging activity were measured during the fermentation. The results illustrated that the fermentation of grey oyster mushrooms would be in NaCl (3.5%) and initial Lactobacillus plantarum (104 CFU/mL). The obtained data showed that although no significant difference was observed among different salt concentrations and inoculum starter culture on the quality of fermented mushrooms, the fermentation conditions enhanced the rising of TPC resulting in an increase in antioxidant activities of fermented oyster mushrooms. This study reveals that fermented grey oyster mushrooms can be used as a source of healthy plant-based foods by vegetarians to improve their nutrition diet.

Natural antioxidant products are receiving great attention as a safe alternative to chemically synthesized ones. For this, the phenolic compounds in the Sesbania sesban L. leaves possess potential antioxidant activities. Therefore, in this study, the Sesbania sesban L. leaf extract (SSE) was prepared and incorporated in the carboxymethyl cellulose (CMC) hydrogel as a natural antioxidant product. Firstly, the SSE was produced by the sonication-assisted extraction method, which demonstrated a total phenolic content of 61.44 ± 7.23 mg gallic acid equivalent/g dry powder weight, and a high antioxidant activity (IC50 = 15.381 ± 1.270 µg/mL). Then, the SSE was loaded into the CMC hydrogel and physicochemically evaluated in terms of physical observation, viscosity, gelation time, and drug release profiles. The hydrogel showed acceptable properties with a gradual release of polyphenol content over two stages for at least 180 min. Finally, utilizing the 2,2-diphenyl-1-picrylhydrazyl (DPPH) test, the antioxidant action of the SSE was well-maintained in the SSE loaded CMC hydrogel. In summary, the SSE loaded CMC hydrogel could be further investigated to become a potential cosmetic in the market.

However, areas such as irrigation, market assistance, and farm-to-market roads still needed improvement. Farmer beneficiaries highlighted the importance of irrigation, fertilizer assistance, market access, training, machinery access, financial support, electrification, and post-harvest facilities for enhancing farming practices. These findings emphasized the need to address water management, input accessibility, infrastructure development, knowledge dissemination, technological advancements, financial support, and value chain enhancement to enhance productivity, profitability, and sustainability in farming activities in Barangay Itombato.

Education is continuously evolving and adapting to meet the diverse learning needs of students. A significant innovation in this field is the flipped class model, a pedagogical approach that redefines the traditional classroom structure. This creative approach seeks to enhance student-centred learning by combining in-class discussion with pre-class video instruction. This paper aims to investigate its effects on undergraduate students' writing performance. In this study, the flipped model was implemented to teach writing lessons, aligning sessions with Bloom's Taxonomy. A quasi-experimental design was employed with two groups of eighty non-English major students at a university in the Mekong Delta, South Viet Nam. The experimental group was exposed to the flipped model, while the control group received conventional writing instruction. The treatment consisted of six 50-minute writing sessions. Results show that students in the experimental group achieved higher mean scores compared to their counterparts in the control group. This finding highlights the effects of the flipped classroom technique in enhancing writing proficiency. Pedagogical implications are suggested for teaching writing to learners who study English as a foreign language.
