While methods to reduce this use have been proposed by researchers, they have not yet been widely implemented by winegrowers. Involving winegrowers in the participatory design of new management strategies could encourage the adoption of these methods to reduce pesticide use. In this study, we designed and tested a participatory approach to reducing pesticide use that would be acceptable to winegrowers from a South-Western cooperative (i.e., not ‘pioneering’ winegrowers). The approach was composed of three main steps: A) co-design of the management strategies, B) implementation of the management strategies, and C) co-evaluation of the performances of the implemented management strategies. Winegrowers, researchers, advisors and engineers were involved in the study. The application of this participatory approach enabled the co-design and testing of two management strategies: IPM for Integrated Pest Management [50% reduction of pesticide treatment frequency index (TFI) as compared to the French High Environmental Value reference (HEV)], and ORG2kgCo for organic farming system with a maximum of 2 kg of copper/ha/year. These two management strategies were implemented by 11 winegrowers in three vineyards in South- Western France. In both management strategies, two main technical levers were selected to reduce pesticide use: a Decision Support System to optimise the use and substitution of pesticides by biocontrol products. The implementation of the IPM management strategy resulted in a significant reduction of TFI (from -14% to -57%, with an average of -25%, for all pesticides combined) compared to HEV, and the winegrowers who tested ORG2kgCo managed to not exceed the limit of 2 kg of copper per year. This original participatory approach, combining co-design workshops, on-farm experimentation and co-evaluation workshops, highlighted the benefits of involving winegrowers in the reduction of pesticide use.","PeriodicalId":14618,"journal":{"name":"Italian Journal of Agronomy","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139781491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results related to functional traits are presented along with the main agronomic and technological parameters that were determined. Several nutritional properties are included. Mean yield and stability performance over environments for each genotype were explored using the “Genotype and Genotype by Environment biplot” elaboration. Considering yield performances, “Benco” was closer to the ‘ideal’ genotype. All the results were evaluated with the farmers, who expressed their own preferences from field observations. The right coupling between environment and genotypes can discourage the abandonment of hilly and mountainous farms by enhancing the economic competitiveness of agriculture in these regions.","PeriodicalId":14618,"journal":{"name":"Italian Journal of Agronomy","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139840702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since cotton is an important economic crop, the cost of its cultivation and the resulting economic benefits are undoubtedly important aspects to be considered. In recent years, the high cost of coating materials and complex production processes have prevented the widespread application of cotton seed coating. Moreover, cotton plants emerge from cotyledons, and the coating material on the seed coat does not play a role after the seed emerges. Given the above shortcomings, to adapt to the mechanized direct seeding method and to include a large number of fertilizers and fungicides, insecticides can be used together with the seed direct seeding into the soil; at the same time, this will improve the cotton seedling emergence rate, the physiological qualities of cotton seedlings after the emergence of cotton seedlings, and the resilience of cotton seedlings in the early stage of resistance ability. In this study, we devised a technique for balling cotton seeds employing components such as cassava starch, bentonite, diatomite, attapulgite, and seedling substrate. The compositional ratios of the method were determined via a growth chamber trial, and we evaluated its effect throughout the cotton reproductive period using field trials. The results showed that the emergence and emergence hole rates of the balled cotton seeds increased by 34.42% and 28.84%, respectively, compared with the uncoated control. In terms of cotton yield, the seed balling treatment increased the number of bolls per plant and the overall cotton yield. Seed balling technology is different from traditional seed pelleting or seed coating techniques. It gathers one or more seeds in seed balls, enabling the simultaneous sowing of multiple seeds of the same variety or different varieties in the same crop. Additionally, seed balls can encourage seeds to carry fertilizer and pesticides into the soil, further weakening soil-borne diseases and abiotic stresses, form a relatively stable internal environment in the soil, and ensure the germination of cotton seeds. Our findings provide a reference point to improve cotton seedling emergence through the utilization of this novel technology.","PeriodicalId":14618,"journal":{"name":"Italian Journal of Agronomy","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2023-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139246640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The intercropping of lentil with wheat can be a valuable agroecological practice for stabilizing crop yields and improving weed control; however, this requires better knowledge about the technical viability, suitable varieties, sowing density, management practices for different conditions, and the feasibility of these solutions for farmers. In this paper, we present a three-stage participatory approach aimed at involving farmers in the evaluation and design of knowledge-intensive agroecological cropping systems and applied it to the case of wheat-lentil intercropping. The proposed approach is articulated into three connected stages involving experiments at different scales (plot, field and farm) and with different grades of interactions among farmers and researchers regarding the design of experiments and the evaluation of the results. In the first stage, we set up controlled plot experiments at an experimental station allowing all interested farmers to observe and comment on the various treatments that were investigated during dedicated events. This stage tested the potential of intercropping to improve the sustainability of the local farming system and provide a solid scientific background to the ecosystem services provided by wheat-lentil intercropping, such as crop production, yield stability, and weed control. While being agronomically beneficial, the technical feasibility and economic benefits of wheat-lentil intercropping have still to be proven. Therefore, based on the results obtained from the first stage and the feedback of local farmers on the opportunities and weaknesses of the on-station application of wheat-lentil intercropping, a second experiment was carried out using commercial agriculture machines with the objective to test the technical viability of intercropping at a larger scale. In the final third stage, we set up a co-designed on-farm experiment aimed at supporting a farmer in establishing lentil-wheat intercropping adapted to the farm conditions. This approach demonstrated that gradually involving farmers in the experimental process, starting from evaluating the most promising agroecological solutions on station to implementing them on farms, supports a successful agroecological transition of farms towards more diversified cropping systems.","PeriodicalId":14618,"journal":{"name":"Italian Journal of Agronomy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136067984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
