This research aimed to estimate winter wheat water consumption and WP in the central clay plain of Sudan by integrating remotely sensed images, climate data, and biophysical modelling. The wheat crop was cultivated under a centre-pivot irrigation system during the winter season of 2014/2015. The Landsat-8 satellite data were used to retrieve the required spectral data. The Surface Energy Balance Algorithm for Land (SEBAL) was supported with RS and climate data for estimating the Actual Evapotranspiration (ETa) and the WP for the wheat crop. The SEBAL outputs were validated using the FAO Penman–Monteith method coupled with field measurements and observation. The results showed that the seasonal ETa ranged from 400 to 600 mm. However, the WP was between 1.2 and 1.5 kg/m 3 during the wheat cycle. The spatial ETa and WP maps produced by the SEBAL model and Landsat-8 images can improve water use efficiency at field scale environment and estimate the water balance over large agricultural areas.","PeriodicalId":45740,"journal":{"name":"Open Agriculture","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135319825","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 consumption of ready-to-eat (RTE) food products, such as fresh vegetables, salads, dairy, pre-cooked meat, or pre-cooked meals, has increased in all western countries. This study aims at characterization of the Portuguese consumers’ attitude toward chilled RTE meat and dairy foods consumption. The study was performed using a questionnaire survey disclosed through an internet platform. The sample consisted of 350 individuals, who voluntarily answered the questionnaire. The survey included questions to characterize the Portuguese purchase and food safety attitudes related to dairy and meat RTE food products. The questionnaire also included questions for the sociodemographic characterization of the sample involved. According to the results, it is not clear to the customers as which is the safer refrigerated RTE food selling format, pre-packed or foods on request. The participants consider refrigerated RTE dairy and meat food products safer when purchased at the delicatessen department in the supermarket than those purchased at open markets or bazaars. With respect to the customers’ habits, they usually purchase RTE dairy or meat food products mainly from the supermarket, and in pre-packed format. Globally, the results reveal that Portuguese consumers are conscious and follow assertive attitudes toward food safety, contributing to maintain the refrigerated food chain, even when they take the product home.","PeriodicalId":45740,"journal":{"name":"Open Agriculture","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43475415","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 level of positive phenotypic correlations of descriptive traits with all group traits of the conformation type and the final score was height (0.19–0.34 and 0.34), chest width (0.06–0.29 and 0.17), body depth (0.28–0.53 and 0.48), angularity (0.35–0.77 and 0.62), rump width (0.29–0.36 and 0.46), rear legs posture (0.33–0.37 and 0.48), front udder attachment (0.23–0.39 and 0.41), height of rear udder attachment (0.17–0.27 and 0.29), and central ligament (r = 0.16–0.39 and 0.36). The body condition score was related to group traits but in a negative value, with correlation coefficients ranging from −0.07 (legs) to −0.47 (dairy strength).

This is because climate change causes high rainfall intensity and a prolonged dry season. Efforts to overcome this are fertilized using bioameliorants so that soil nutrients remain available for plants. Observations have been made from May to August 2018 at the JAMTANI Field Laboratory. The study used a factorial randomized block design with three replications. The first factor was a bioameliorant (P1 = goat manure 10 tons ha−1; P2 = goat manure 10 tons ha−1 + Azolla pinnata 10 tons ha−1; P3 = goat manure 10 tons ha−1 + Sesbania rostrata 2 tons ha−1; dan P4 = goat manure 10 tons ha−1 + A. pinnata 5 tons ha−1 + S. rostrata 1 tons ha−1) and the second factor was rice varieties (Ciherang and Mendawak). The application of bioameliorant increased C-organic of soil by 9.04% to 20.41% and soil nitrogen by 11.76% to 38.24%. The addition of bioameliorant did not cause differences in the weight of the plant between the Mendawak variety (61.34 g) and the Ciherang variety (56.96 g). The most efficient addition of bioameliorant is P3 (goat manure 10 tons ha−1 + S. rostrata 2 tons ha−1) with nutrient uptake efficiency value reaching 5.77%.

The purpose of this meta-analysis was to explore the influence of substitution of maize with dietary cassava on growth traits (i.e., average daily feed intake [ADFI], body weight gain [BWG] and feed conversion efficiency [FCE]) of broilers. Search done in PubMed, Google scholar and Scopus databases yielded 303 studies of which 27 were suitable for the analysis. Heterogeneity was explored by subgroup and meta-regression analyses using the following moderator variables: publication year, study continent, processing methods, cassava form, substitution level, broiler strain, number of birds per groups and treatment durations. Results show that dietary cassava reduced ADFI (mean difference [MD] = −5.19 g/day; 95% confidence interval [CI]: −8.60, −1.79; I 2 = 99%) and BWG (MD = −8.49 g/day; 95% CI: −9.65, −7.33; I 2 = 98%) and increased FCE (MD = 0.29; 95% CI: 0.24, 0.35; I 2 = 99%) in broilers compared to controls. Publication year, broiler strain, treatment durations and substitution level) influenced the outcomes of the study and explained some of the sources of heterogeneity. In conclusion, our results suggested that dietary cassava inclusion at 5% (minimum) and 62% (maximum) reduced growth performance in broiler chickens.

Isolates were selected based on their ability to solubilize phosphate, produce indole-3-acetic acid, and improve seed germination and seedling growth under laboratory conditions. Following this screening, eight bacteria were selected (S1, S4, S13, S14, S16, B9, B11, and B15) to assess their performance on seedling growth in greenhouse. Seeds of two tomato varieties (one improved, Raja, and the local one, Foolewouh) were used in this study. The experiment was performed in sterilized and non-sterilized soils. Phylogenetic analysis of the 16S rRNA sequence showed that these bacteria belong to the genus Bacillus, including B. thuringiensis, B. cereus, B. pacificus, and B. aerius. The bacterial performance depended on the variety and conditions of soil treatment. Isolates improved seed germination (up to 31.93%) and seeding strength (up to 78.59%) in vitro. In greenhouse, inoculation with PGPB significantly increased stem height, root length, and weight of fresh and dry stems and roots. Raja variety was more sensitive to bacteria and performed better than the Foolewouh variety. Bacterial isolates on sterilized soil allowed to better seedling growth compared to non-sterilized soil.
