Various methods exist to mitigate heat stress such as genetic and nutritional approaches, air conditioning, ventilation, and antibiotic growth promoters but they are often expensive and not always adequate. Keeping this view in mind, research has been focused on medicinal herbs which are available, cheap and safer to use. Amla fruit possesses antioxidant, antimicrobial, and anti-stress properties that could mitigate heat stress’s harmful effects on broilers. Therefore, this study was conducted to evaluate the impact of amla fruit powder on growth performance, gut microbiota and blood lipid profile of broilers under ambient temperature and heat stressed condition. A total of 126 broiler chicks were divided into two major groups, one group kept under ambient temperature and another group exposed to heat stress. Each major group was split into 3 subgroups with 3 replications having 7 chicks per replication. In case of each major groups, first sub groups were kept as a control and latter two groups were supplemented with 0.5% and 1.0% amla fruit powder, respectively. Total duration of the experiment was 35 days, where treatments were given with basal diet from 12 days. All the experiment birds were maintained with the similar management except the experimental diets. The results showed that body weight and body weight gain at the end of the experiment were higher in amla treated group than in the control group at both temperatures. Supplementation of amla fruit powder also improved feed conversion ratio (FCR) and dressing percentage than the control groups. Additionally, amla powder reduced TC, TAG and LDL levels and slightly increased HDL content. Amla fruit powder decreased pathogenic bacterial population such as Escherichia coli and Salmonella spp. concentration in the gut and increased probiotic bacterial concentration such as Lactobacillus spp. under both rearing temperatures. Taken together, it can be concluded that, amla fruit powder could be used as an alternative tool to improve broiler performance and mitigate the deleterious effects of heat stress on broiler chickens.","PeriodicalId":11865,"journal":{"name":"European Journal of Agriculture and Food Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135218826","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 needs for traditional medicine, which are present in both local and international markets, are met in large part by medicinal and aromatic plants (MAPs). Due to the abundance of medicinal plants, people in many tribal and rural parts of Bangladesh, like many other nations, have traditionally relied on nature and natural remedies to heal themselves and avoid ailments. The market is flooded with items made from medicinal and aromatic herbs. Plants can be used to produce specialty materials like biocides, cosmetics, medicines, essential oils, dyes, and colorants. Most of the species of MAPs are produced for such industrial uses, but most of them are still wild collected. The increasing demand in botanicals results in a great trade from local to international level. Identifying the significant role played by MAPs in serving health and well-being security, it is very important for the countries to utilize the need to conserve, sustainably use, and commercialize the MAP biodiversity resources responsibly throughout the world. The total trades in MAPs have increased from 2.4 billion USD in 1996 to 6.2 billion USD in 2013 with annual growth rate of 5.4% in past 18 years, and growth rate of 10.7% is noticed in recent years. By 2023, it will be expected that the market for herbal medicines would develop at a compound annual growth rate (CAGR) of 5.88% and reach USD 1,29,689.3 million. Nowadays, roughly 80% of the world’s population gets their healthcare mostly from plants and plant extracts. According to a World Health Organization (WHO) forecast, the worldwide herbal industry would reach $5 trillion by the year 2050. China, India, Hong Kong, USA, Germany, Republic of Korea, Canada and Poland are the top export countries while top destinations include USA, Hong Kong, Japan, Germany, France, Republic of Korea, China and Singapore. The study suggests five major trade centers of MAPs worldwide viz. USA, Hong Kong, Germany, Republic of Korea and China. A number of Non-Governmental Organizations (NGOs), Governmental Organizations (GOs) and International Non-Governmental Organization (INGOs) have been working on improvement and expansion of commodity-wise value chains for selected MAPs throughout the world. For commercial developments of MAPs sub-sector, it is required to gather experiences of technical, socio-economical, institutional and policy inputs.","PeriodicalId":11865,"journal":{"name":"European Journal of Agriculture and Food Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135665234","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}

Agroforestry practices are critical in all agro-based sectors like tea industry because of benefits like provision of fuel wood for curing tea. The purpose of this study was to understand the current agroforestry practices adopted by smallholder tea estate farmers and investigate options for scaling up the technology to alleviate the fuelwood scarcity faced by tea industries. The study involved a survey that was conducted in Kyenjojo district located in Western Uganda in June 2020. A total of 65 small holder tea farmers (respondents) were interviewed during the study. A purposive sampling method was used and data analyzed with SPSS to generate descriptive statistics that included frequencies, percentages, tables, graphs and charts. Results showed that shade was the most benefit of agroforestry trees by a proportion of 33% towards tea growing and followed by climate modification at 24%. Protection of the environment was also revealed as one of the leading benefits of tea agroforestry with a proportion of 34%, as well as trees acting as a source of poles at 23%. Eucalyptus at 34% was the most dominant agroforestry tree used at tea farm level as a woodlot, followed by Grevillea robusta at 28%. The most dominant adoption method of tea agroforestry practices at tea farm level was through farmers learning from fellow farmers at 34%, followed by adoption by trainings at 23%. Planting of agroforestry trees was the only remedy stated by farmers as an effort done to retain trees on farm. As a recommendation towards increased uptake of agroforestry at farm level, farmers identified certification and other factory-based incentives such as Rain Forest Alliance being the most important. Based on the identified benefits of tea-agroforestry systems, efforts should be made by Public, Private and Development partners to make all tea farmers aware of the existing and appropriate agroforestry practices while developing appropriate incentive models for increased adoption of tea agroforestry system in Uganda.","PeriodicalId":11865,"journal":{"name":"European Journal of Agriculture and Food Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136034639","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}

In a field experiment, eight boro rice varieties were evaluated (five inbreed varieties, two high-yielding varieties, and one wild variety) to observe varietal performances against blast disease. A pot experiment was also performed to study the resistance behavior of the tested varieties in an in-vitro condition by applying silica powder, K2SiO3, salicylic acid, cattle urine (both normal and pregnant cows), and PPN. Field study revealed that the wild variety was highly resistant (incidence and severity 0%) whereas BRRI dhan58 was susceptible (incidence 21.48% and severity 60.48%). Wild variety was also characterized by the highest tiller number (20.73), panicle length (24.90 cm), fresh grain weight (62.30 g), and dry grain weight (51.70 g). The highest number of panicles was recorded in BRRI dhan28 (18.40) which was statistically like the wild variety (17.50). Though wild variety performed best in another parameter it gave the lowest amount of yield (4.77 kg/plot). In morphological studies of pathogen, pyriform-shaped conidia were found in a sympodial fashion on conidiophores whose size varied from 22.13 to 28.47 μm × 9.13 to 11.72 μm (average 25.30×10.43 μm).

Three separate multistory agroforestry systems were covered by the three treatments, while an open field served as the control treatment. to keep track of the system's expansion and economic success; soil analysis, photosynthetically active radiation, plant height, number of leaves, head length, head width, head weight, total yield, BCR, and LER were calculated following different established methods. While compared to sole cropping, the agroforestry approach drastically reduced the production of broccoli by 89%. Soil organic matter, nitrogen, phosphorous, potassium, and sulfur were higher in agroforestry system than that of control plot. In fact, the agroforestry system had some negative effects on the rate of crop growth in understored conditions. Despite, net return and BCR from aonla-based multistoried agroforestry system were 4-11 lakh and 2.24-3.98, which was 69-87 and 41- 67 %, respectively higher than sole cropping systems. The LER of aonla based multistoried agroforestry system was 3.20.

Many studies have been conducted to determine the effects of climate variability and change on rice productivity in Bangladesh. This study aimed to investigate the relationship between rice crop production and climate variables (namely, average temperature, rainfall, CO2, and humidity) and find out the best model that has an actual impact on rice production. Selecting 'potential predictors' from numerous possible variables to influence the forecast variable and investigating the most appropriate model with a subset of the potential predictors are two major difficulties of fitting the multiple linear regression model. Best subset regression and stepwise regression were used to fit the model using R software. Our results revealed that temperature and CO2 were statistically significant for rice production at 5% and 1% levels of significance respectively. From Adjusted R2, climatic parameters account for 17.39 percent of the variation in rice production. Temperature and CO2 are the best predictors, according to model Cp and AIC values, and stepwise regression also supports this finding.
