Both human and animal health are adversely affected by these hazardous secondary metabolites. They can get into the food chain through tainted fruits and crops as well as through processed foods and animal feed. Products from agriculture and the food industry, such as cereals, spices, nuts, fruits, vegetables, and dry fruits, might contain aflatoxin B1. It has been shown in numerous investigations that feeding broilers pure aflatoxin B1 has a negative impact on their growth. Higher levels of Aflatoxin B1 (1–5 mg/kg) have been shown to be hepatotoxic to broilers, causing pathological liver lesions. The impact of broiler food contaminated with high or low levels of aflatoxins on the health and sustainability of production, however, has not been thoroughly explored in the literature. Although most of the experiments produced modestly beneficial benefits, substantial outcomes were infrequent. There needs to be more investigation because there are practically infinite options for aflatoxin B1 dosage and length of exposure. Results comparison becomes challenging when there is a lack of standardization. To assess the ideal aflatoxin B1 dosage, the precise mechanism of action, and its effects on the sustainability of broiler meat production and residues of aflatoxin B1 in broiler meat, additional research under more standardized conditions is still required.","PeriodicalId":34040,"journal":{"name":"SVUInternational Journal of Agricultural Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46753552","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}

The first ratoon crop and plant cane both displayed the same trend in terms of quality features.When sugarcane was planted late (in May), bud chips produced better yields of canes and sugar per hectare than cane cuttings did in the plant's cane and first ratoon (14.95 and 3.23 tonnes and 10.20 and 2.07 tonnes, respectively). Meanwhile, May's late planting resulted in a significant decline in the values of the examined quality parameters of both the plant and the first crop of rats . Applying the bud chips approach had a comparative economic advantage over the traditional planting of cane cuttings in both early and late sugarcane planting, in terms of planting expenses, gross and net return, as well as benefit-cost ratio.","PeriodicalId":34040,"journal":{"name":"SVUInternational Journal of Agricultural Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47638453","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}

To determine the best seaweed extracts that can promote growth and produce a higher grain yield of ratoon lowland rice. Evaluate the profitability of rice ratooning as influenced by foliar application of seaweed extracts grown under high maximum temperatures. The experiment was implemented following a Randomized Complete Block Design (RCBD) with the spraying of seaweed extracts as a treatment. The different seaweed extracts used were Guso (Eucheuma dentilatum) , Samo ( Sargassum aquifolium), and Loci (Sargassum polycystum) . Results revealed that spraying with fermented Sargassum polycystum extract achieved a higher grain yield (1.24 t ha -1 ) and eventually a higher gross margin (USD 283.40) of ratoon lowland rice than unsprayed control and those plants sprayed Algafer commercial foliar fertilizer. Foliar application of seaweed extracts did not influence all parameters gathered even though higher productivity in plants applied with Sargassum polycystum and Sargassum aquifolium extracts. The real effect of foliar application might be due to the plant's exposure to high maximum temperatures that might reduce the absorption and translocation of applied nutrients into the ratoon crops. Thereby decreasing productivity but still higher compared to commercial foliar fertilizer. This study speculated that foliar application of seaweed extracts is one of the best options to alleviate the crop productivity that might experience low yield due to soil problems, although enhancing its productiveness when plants are grown under normal environmental conditions.","PeriodicalId":34040,"journal":{"name":"SVUInternational Journal of Agricultural Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41347602","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}

The study recruited 180 processors following three (3) stage sampling procedure. Primary data was collected with a validated and reliable interview schedule. Descriptive and t-test statistics were employed to analyze data. Results revealed that 91.1% of the processors were females with average age of 47.6 years while 56.7% had primary education. It was also found that 72.2% of the processors sourced for information about JICA technologies through agricultural extension agents. Study also found that all JICA technologies were effective. However, quality parboiling of paddy rice with the false bottom ( X̅ = 3.99) and soaking method ( X̅ =3.98) and whole grains realized when milled by Ajifa ( X̅ = 3.98) were the leading JICA technologies considered effective by the respondents.

The results revealed significant interactions between planting date and genotypes on seed yield/plant in both seasons and the number of umbel/plant in the 2 nd season.

Under the latter extreme conditions, treating plants with silica products was the common managerial practice used for enhancing uptake and plantation. A split-split plot experimental design with four replicates was used to conduct the research in Oraby Village, Maryout area, Alexandria, Egypt in the last year of the most water-scarce decade. The aim of the experiment was to put the sink/ source term of Richard’s equation, S, into consideration under a macroscopic electrical modeling, AMUN_SHC. The S-shaped relative stress response function was used to describe the relation SSI= f (h, z, t). AMOUN_SHC showed that the sink term of Richard’s equation is the product of multiplying the soil hydraulic capacitance and soil stress index. The soil stress index, plant stress index and strain of straw sap were calculated. The soil hydraulic capacitance was derived estimated and discussed. The effect of silicon as a beneficial element on the soil hydraulic capacitance and therefore the winter wheat water uptake was estimated and discussed.
