Improvingyields in organic farming: data and knowledge within the OrganicYieldsUPproject
Improving yields in organic farming remains oneof the main challenges for the consolidation and expansion of this productionmodel across Europe. This objective is constrained by a significantlack of systems for continuously monitoring organic production, reflected inthe near absence of databases specifically designed to capture theparticularities and complexity of organic farming. It is in this context that, within theframework of the OrganicYieldsUP (OYUP) project, a database has beendeveloped bringing together detailed information on organic farming systemsacross a range of European contexts, with the aim of supporting the analysis ofthe factors that influence crop productivity and performance.
This database brings together contributionsfrom several European countries, including Switzerland, Germany, Denmark,Estonia, France, Hungary, Italy, Luxembourg, Poland, Sweden, Slovakia andSpain. The information collected, covering a period of over three decades, fromthe early 1990s to the early 2020s, results from a variety of researchapproaches, including factorial field trials, system comparison studies,variety trials and monitoring activities on commercial farms, performed over aslittle as one year and as much as 27 years. This diversity reflects both theheterogeneity and complexity of organic farming systems, as well as the varietyof research methodologies applied across Europe. At the same time, ithighlights the significant challenge of integrating such varied informationinto a single, unified database.
Despite the breadth of information collected,the availability of different types of data is not uniform. While farmoperation data and rotations are relatively well represented, indicatorsrelated to soil properties and crop protection appear in fewer datasets. Thisimbalance makes it possible to identify both the strengths of the informationcurrently available and areas where data collection remains more limited.
An analysis of the volume of observations alsohighlights marked differences between countries and between types of study. Asubstantial share of the data derives from factorial field trials and varietytrials, whereas farm-level monitoring is concentrated in only a few specificcontexts. This distribution primarily reflects differences in the datacollected and reported by the participating partners, rather than the broadernational research infrastructures or priorities in organic farming.
In addition to data from organic systems, thedatabase also includes a smaller set of observations relating to conventionalsystems, collected mainly within the context of comparative trials. Althoughthese data represent only a fraction of the total information available, theyallow certain analyses to be placed within a broader frame of reference. For more advanced analytical steps—such as calculating organic yieldgaps—the database will be further enriched with data from official statisticson conventional cropping systems.
The distribution of data across crops,countries and time periods shows a clear concentration in certain crops andregions, as well as within specific temporal windows. This aggregation islinked to the historical focus of research on some major crops and moreintensively studied contexts, while at the same time highlighting gaps inrelation to intermediate crops, more diversified systems and less representedregions.
The database developed within theOrganicYieldsUP project constitutes an important resource for advancingknowledge on the factors that influence yields in organic farming. At the sametime, the uneven distribution of information underlines the need for caution ininterpreting results and extrapolating conclusions, pointing to the importanceof careful analytical approaches and future efforts to further expand andrebalance the database.
