The study aimed to reflect on the promotion of digital payments among smallholder tea farmers in Kanungu District, Uganda. The study was guided by specific objectives, namely, investigating the effect of digital payments on financial deepening, assessing the effect of inflation rates on Uganda's economic literacy, determining the influence of per capita income on Uganda's economic literacy, and evaluating the effect of foreign direct investment on Uganda's economic literacy. The study used a descriptive research design utilizing a quantitative approach. The average cash payment was 3,862,241,831 before the introduction of digital payments such as mobile money and banks and after the introduction of digital systems, the cash payment decreased significantly to 3,895,754. However, after introducing digital systems, the payment of smallholder farmers increased significantly from 2,379,988,876 to 2,500,825,890 which implies that there was a huge improvement as well as an increase in the profitability rate of the factory. There was a strong significant negative relationship between digital payments and gross domestic product (-0.768). Understanding the factors that influence the adoption of digital payments can assist in identifying the obstacles that hinder some societal groups from using digital financial services. Then, specific actions can be developed by policymakers as well as financial institutions to encourage financial inclusion. The flexibility of the created models to satisfy the requirements of agricultural stakeholders and to react to their limits is crucial for the success of innovative tools in rural areas.

Honeybees play a crucial role in plant pollination, agriculture’s biodiversity, and environmental balance. This study was conducted for the first time in "the Golden Triangle Area". The objective was to identify the bee species that inhibited the Red Sea, focusing on the coast. The work was conducted through intensive and extensive visual observation on a 20 km long and 2.5 km wide area. Morphological measurements using a stereomicroscope and molecular identification were conducted using the mitochondrial COI gene. Body, antennal, forewings, hind wings, and hind leg lengths were recorded. The mitochondrial COI gene confirmed the species identification of dwarf bees in the studied area. COI sequencing produced a nucleotide length of 636 bp. and was deposited in GenBank under accession number (OP797664.1). The COI sequence was subjected to BLAST/N at the NCBI and revealed eight species of the genus Apis . On average, colonies were found to be about five per square kilometer. Also, the most preferred plantation for the red dwarf honeybees was sider trees. In conclusion, dwarf honeybees moved to the Triangle Golden Zone, which, if taken into consideration, will enrich the agriculture ecosystem. Also, increasing sider trees will increase the natural colonization of dwarf

The study aimed to estimate the production economics efficiency indicators for the cultivated wheat crop in the salt-affected lands in Sharkia Governorate. A sample of 102 households has been randomly selected from the studied area. The distribution of farm households across the defined five Villages (clusters) was determined. Interviewed farmers were randomly selected from the five studied villages. The results revealed: First: The effects of a 10% decrease in wheat productivity on indicators of economic efficiency in lands affected by salinity according to farm size are: (1) for the farmer. Small, both total costs and variable costs per unit increased by 11.1%. Farm margin, net profit per acre, net water return, casual margin per acre, and water productivity decreased by 25.4, 16.1, 16.1, 12.1 and 10.0%, respectively. (2) For large farms, total costs and variable costs per ardab were increased by 11.1%. Farm margin, net profit per acre, net return on water crossing, margin per acre, and water productivity decreased by 25.2, 15.6, 15.6, 11.8 and 10.0%, respectively. (3) At the average level, total costs and variable costs per ardab increased by 11.1%. Farm margin, net profit per acre, net return on water, margin per acre, and water productivity decreased by 25.3, 15.8, 15.8, 12.0 and 10.0%, respectively. Second: The effects of a 20% increase in wheat seed prices on indicators of economic efficiency in lands affected by salinity according to farm size. At the average level, the total costs and variable costs per ardab increased by 1.3% and 1.9%, respectively. Farmers' margin, net profit per acre, net water return, casual margin per acre, and farmer incentives decreased by 3.0, 1.5, 1.5, 1.1 and 1.5%, respectively. The research recommends the need to maintain lands affected by salts due to their impact on the productivity of the wheat crop, as well as so that agriculture can continue.

The experiment was conducted on a private farm in Sharm El Sheikh City, South Sinai Governorate, Egypt during the summer seasons of 2020 and 2021 to examine the effects of four different colors of shade nets (green, blue, grey, and black shading net) and four soil mulch materials (organic mulch and both black and silver plastic mulches, as well as without soil mulch) on shielding cucumber plants from high temperatures, improving microclimate as well as growth, quality, and fruit yield. The results demonstrated that the use of colored shade nets altered the microclimate around cucumber plants, resulting in a drop in average monthly both air temperature and light intensity as well as an increase in air relative humidity when compared to un-shaded treatment. Furthermore, the temperature of the soil was higher without mulch than it was with mulch. The findings showed that cucumber plants covered in green nets combined with organic soil mulch had the highest values of vegetative development features, such as root length, plant height, number of leaves, and both fresh and dry weight of plants, followed by black shade nets with organic soil mulch. Also, the outcomes revealed the highest values of yield per fed. were attained by green shade nets and/or black nets interacting with soil organic and/or black soil mulch. The results analysis indicate that P-fruit content created the most significant effect from the combination of grey shade nets with organic soil mulch. In terms of N-fruit content, cucumbers covered by green shade nets with organic soil mulch or/and black soil mulch had the greatest values.

Natural pollen feeding induces a wide range of morphological and anatomical changes in honey bees. The worker honey bee is used to determine the effect of the natural feeding of two different types of pollen collected by the honey bee upon the development of the stinger, venom sac length, and bee venom production. This experiment was carried out in 2022 during the period from May to August in two private apiaries, where honey bee colonies are fed naturally on pollen collected from clover plants. In the present experiment, it was assessed how different plant impact the stinger and venom sac length. The results clearly showed significant differences in the stinger and venom sac parameters between the workers fed on clover plants and those fed on clover for the clover plant pollen. The present study showed that bees fed on clover pollen have longer stingers than that fed on corn pollen, also venom sac length (t=5.987; p < 0.000), and venom sac width (t=9.205; p < 0.0001) for worker bees fed on clover pollen compared to worker bees fed on corn plant pollen, the same for other parameters which showed significant differences in the Stylet length (t=7.216; p < 0.0001), and the lancets length (t=7.216; p < 0.0001), barbs lancet length (t=9.205; p < 0.0001. These results indicated that the development of the stinger, venom sac parameters, and quantity of collected bee venom is extremely sensitive to the type of nutrients.

Experiments were conducted on cucumber plants under greenhouse conditions (Barracuda cultivar) at Armant district, Luxor Governorate, Egypt, throughout two successive growing seasons (2021 and 2022) to study the population dynamics of the whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae). The effect of temperature, relative humidity, and plant development on the oscillations of B. tabaci was studied. The results cleared that the number of B. tabaci individuals was detected on cucumber plants during the period from January 23 rd till April 17 th , i.e., the insect infestations appeared on plants that were eight weeks old after emergence (WAE) in 2021 season. While, it appeared during the interval from March 6 th until July 9 th , i.e., the injuries discovered on plants that were thirteen weeks old after emergence (WAE) in 2022 season. Furthermore, the total estimates of B. tabaci during the first growing season (2021) were smaller than those during the second growing season (2022). In the two seasons, a gradual increase in the numbers of B. tabaci on cucumbers was observed during the month of April, indicating that the management of the pest should begin before it reaches its highest level, during the seedling and flowering stages. The results indicated that the influences of weather circumstances and plant development on B. tabaci abundance were highly significant over the two seasons studied and that these variables varied from season to another. As well, the percentages of explained variance were 98.05 and 93.43% in the two seasons, respectively. This information can help establish a greenhouse whitefly management and monitoring programme.

Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae), poses a significant threat to newly targeted okra plants. This pernicious pest can be found on all plant parts, leading to desiccation and ultimate demise. Our study aimed to examine the spatial distribution pattern of P. solenopsis infestation in okra plants, specifically focusing on the Balady cultivar, over two consecutive seasons (2021-2022) in the Luxor region of Egypt. We employed insect counts and determined the percentage of infested plants to characterize the insect population. Our findings revealed that P. solenopsis infestation on okra plants emerged five weeks after planting (WAP) and persisted until harvest in every season. During each season, we observed three distinct peaks in population numbers and infestation rates of P. solenopsis . Notably, the initial season exhibited higher overall quantities of P. solenopsis compared to the subsequent season. At 20 WAP, we observed the most suitable time for population estimates to increase, while at 5 WAP, it was the least favorable for activity during both seasons. Statistical analysis of variance demonstrated significant variations in P. solenopsis population estimates and infestation percentages across different inspection periods. Additionally, through nonlinear regression analysis, we elucidated the relationship between P. solenopsis numbers and phenological development. Data were evaluated using dispersion measures, and all P. solenopsis dispersal indices had substantial aggregated behavior and were strongly related to the host's phenological evolution during each season. Based on the available data, we can develop effective strategies for monitoring and controlling mealybugs in okra plants.

We employed insect counts and determined the percentage of infested plants to characterize the insect population. Our findings revealed that P. solenopsis infestation on okra plants emerged five weeks after planting (WAP) and persisted until harvest in every season. During each season, we observed three distinct peaks in population numbers and infestation rates of P. solenopsis . Notably, the initial season exhibited higher overall quantities of P. solenopsis compared to the subsequent season. At 20 WAP, we observed the most suitable time for population estimates to increase, while at 5 WAP, it was the least favorable for activity during both seasons. Statistical analysis of variance demonstrated significant variations in P. solenopsis population estimates and infestation percentages across different inspection periods. Additionally, through nonlinear regression analysis, we elucidated the relationship between P. solenopsis numbers and phenological development. Data were evaluated using dispersion measures, and all P. solenopsis dispersal indices had substantial aggregated behavior and were strongly related to the host's phenological evolution during each season. Based on the available data, we can develop effective strategies for monitoring and controlling mealybugs in okra plants.","PeriodicalId":34040,"journal":{"name":"SVUInternational Journal of Agricultural Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41741288","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}

Bananas are one of Indonesia's potential horticultural commodities. The global market favors bananas because they are affordable and highly nutritious, whose exports can be used to increase the country's foreign exchange. During the last five years, Indonesia's banana production has continued to increase, making bananas the most significant fruit production of the whole national fruit. However, when viewed from the other side, Indonesia's banana exports are relatively low. So it is necessary to know the performance of Indonesian banana exports in the international market. This study aims to analyze the performance of Indonesia's banana exports in the five major destination countries, such as China, Malaysia, Japan, United Arab Emirates, and Singapore. The method in this research is Constant Market Share. The analysis results show that the standard growth effect of Indonesia's export performance is better than the world standards growth. The commodity composition effect shows that the contribution of Indonesian bananas is relatively high in the international market. Regarding market distribution effects, Indonesia can distribute and dominate the export market share of bananas in China, Malaysia, and the United Arab Emirates. Furthermore, the competitiveness effect, Indonesia is a strong competitor as a banana exporter to Malaysia, Japan, and Singapore. The conclusion from these four aspects is that Indonesia's export performance as a whole is good. The government must provide the appropriate policies through promotion, bilateral cooperation, product quality improvement, and affordable prices. It is hoped that Indonesian bananas will have strong competitiveness and be able to fulfill international market demand.

In ovo feeding refers to a method of delivering nutrients or supplements directly to the developing embryo inside the egg before it hatches. This method is commonly used in the poultry industry to improve the health and performance of the chicks after they hatch. One specific application of in ovo feeding is the use of probiotics. Probiotics are beneficial bacteria that can help improve gut health and overall immune function. By delivering probiotics directly to the developing embryo in ovo feeding can help establish a healthy gut microbiota early on leading to improved health and performance in the hatchlings. Probiotics can compete with harmful bacteria in the gut preventing them from colonizing and causing infections. This can reduce the need for antibiotics as the chicks are better equipped to fight off infections naturally. This can lead to better growth rates and feed conversion efficiency in the chicks. In ovo feeding probiotics is a relatively new and evolving technique in the poultry industry. Research is ongoing to optimize the delivery methods doses and types of probiotics used. Overall, in ovo feeding probiotics is a promising approach to improve the health and performance of poultry. By supporting the gut microbiota early on in the development of the chicks the benefits can be seen throughout their lifespan. Continued research and advancements in in ovo feeding techniques will likely lead to further improvements in the future.
