The results demonstrated that the application of organic amendments and bio-fertilisers enhanced leaf nutrient status as well soil health parameters. The highest concentrations of total N, K, Fe and Zn in the leaves and concentrations of organic, inorganic and total carbon, total N, available N, K, Fe, Mn, Cu and Zn and abundance of bacteria, fungi and actinomycetes in the soil were recorded with T10. Thus, T10 was considered the most effective in terms of increasing leaf nutrient status and soil physico-chemical properties in the Khasi mandarin production system.","PeriodicalId":8904,"journal":{"name":"Biological Agriculture & Horticulture","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45328416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All products affected T. erytreae survival in both types of trials. In the semi-field trial, diatomaceous earth resulted in the highest percentage mortality of T. erytreae nymphs, followed by kaolin, apart from on the final day of assessment when the highest mortality was recorded for paraffin oil, though this effect was not significantly different to that of the other insecticides. In the 2018 field trial, orange oil treatment resulted in the highest mortality rate of T. erytreae nymphs, followed by azadirachtin and garlic extract.

Agrofilm mulches can be used to reduce soil water evaporation as well as to control weeds. The SoilTain DW® geotextile blanket, which is a solid waste material generated in water treatment plants, has the potential to be used for mulching in agriculture. The aim of this study was to evaluate the technical feasibility of using this geotextile waste material as an alternative to different agrofilms for mulching in lettuce under the semiarid conditions of the state of Alagoas, Brazil. Four experiments were carried out in 2020–2021, each with four mulching treatments (white and black polyethylene, geotextile blanket, uncovered soil). Soil surface temperature, plant density, weeds and biometric parameters of the lettuce were assessed and evaluated by univariate and multivariate statistical analyses. Significant treatments × experimental period interactions for all lettuce parameters were observed, except for root biomass. Experiment 2 (winter) presented the most favourable environmental conditions for plant development (mild temperatures) and resulted in an average yield of 25.0 Mg ha−1. In Experiment 1 (autumn/winter), high temperatures (47.9°C) under the black polyethylene reduced plant density (96,800 plants ha−1), though leaf length (16.2 cm) and yield (13.1 Mg ha−1) were not significantly affected. The two canonical variables explained 97.7% of the total variation, forming three similarity groups by Tocher method. All mulches effectively controlled the weeds. Application of the geotextile blanket was concluded to be technically feasible, but it was not recommended for use in the summer when temperatures are high.","PeriodicalId":8904,"journal":{"name":"Biological Agriculture & Horticulture","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47963593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present short-term trial, the effects of dry mulching, green manure and compost treatments were evaluated as restoration strategies to enhance soil functionality in degraded vineyard areas at two Tuscan farms that had been under organic management for different lengths of time. Soil nematode community, soil physical and chemical properties were monitored as indicators of soil quality. The restoration treatments scarcely affected soil chemical or physical qualities; only the compost application increased soil total organic carbon (TOC). Bacterial feeder nematodes increased under dry mulching in response to the organic carbon inputs on the farm in conversion. Plant-parasitic nematodes decreased only after the first year of the restoration treatments and predators decreased during all 3 years. Nematode indicators showed only a few differences between the different management regimes; the diversity weighted abundance expressed as biomass indicated that the restoration practices sometimes represented a disturbing factor in ecosystem services regulation. The abundance of nematode taxa was differently affected by soil physico-chemical properties. On the farm that had been managed organically for longer, the higher proportion of large sized stable aggregates and greater soil porosity benefitted large nematodes such as predators, while the higher moisture levels were unfavourable for some plant-parasitic nematodes. However, on the farm still in conversion, increases in TOC and C/N ratio values were associated with a reduction in plant-parasitic nematodes.","PeriodicalId":8904,"journal":{"name":"Biological Agriculture & Horticulture","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42291062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the application of exogenous plant hormones has become widespread in recent years, data regarding the response of interspecific grapevine cultivars to treatments with biostimulants are scarce.

The application of GA3 at 50 mg L−1 increased the plant productivity (36%), promoted fruit growth and rachis elongation, improved the percentage of the marketable yield (by 5.5%), balanced the sugar/acidity ratio, but affected the synthesis of phenolic compounds. Foliar application of Cropmax® at 2.5 mL L−1 significantly improved the berry diameter, and sugar and anthocyanin accumulation, but grape acidity remained high. All treatments allowed the normal development of plant phenophases and grape maturation, but GA3 application slightly extended the number of days of the annual biological cycle of the Moldova hybrid cultivar (up to 5.5 days), probably due to a temporary variation in the physiological parameters (except for stomatal conductance), as determined in mature leaves after the application of the exogenous growth regulator.","PeriodicalId":8904,"journal":{"name":"Biological Agriculture & Horticulture","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45149095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Foster cow systems, where foster cows stay with calves in low-input pasture-based systems, have been implemented in France since 2010. The aims of this study were to explain farmers’ motivations for establishing their cow-calf contact systems and to describe the ways in which they have implemented them, in terms of daily practice and as part of their organic dairy farm. A documented investigation of the introduction of these rearing systems in France was carried out. In addition, individual semi-structured interviews were conducted between January and March 2019 on 20 organic farms that had implemented this practice. Farmers’ perceptions of the practice were explored through content analysis of the interview responses. Calves were separated from their dam after an average of 4.5 days. The bonding phase was conducted by leaving them together for 2–7 days in small bonding pens. Weaning and separation took place either simultaneously or gradually, between the age of 4–10 months. The farmers perceived these systems as working very well and being easy to implement on grazing-based farms, as well as ensuring good profitability and working conditions. According to the farmers, the calves appeared to have high growth rates and good health status, enabling the first calving at a younger age. These rearing systems seemed to be compatible with an agroecological transition.","PeriodicalId":8904,"journal":{"name":"Biological Agriculture & Horticulture","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42444493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Until 31st December 2021, the protein quality in organic pig feed in Europe was improved by using 5% conventional components, mainly potato protein. To investigate the effects of 100% organic feeding on growth performance, meat and fat quality in pigs, a total of 700 fattening pigs were studied in an on-farm feeding trial. The 95% organic diet fed on each farm served as the control diet (CON) and a 100% organic diet with higher proportions of soybean cake and grain legumes was used as the experimental diet (ORG). ORG-fed animals had slightly lower daily weight gains, lower carcass weight, and significantly higher iodine and PUFA values in the backfat. The feeding trial showed that the 100% organic diet led to a slightly deficient dietary amino acid profile and thus to slightly lower performance in a few traits. However, the implementation of consistent 100% organic feeding was considered valuable for organic farming even with the lower performance and change in meat and fat quality of the organic pigs.","PeriodicalId":8904,"journal":{"name":"Biological Agriculture & Horticulture","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49077189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
