Imagine, test, evaluate and adapt innovations to support the agroecological transition on the farm
January 06, 2022
In order to support the agroecological transition on farms, the CASDAR OUTILLAGE project (operational resources for OUTILLing the step-by-step design of agroecological cropping systems on farms) aims to develop tools to support farmers. Led by Terres Inovia and involving 22 partners, the OUTILLAGE project has made it possible to develop decision trees, dashboards and observation methods enabling farmers and their advisors to imagine, test, evaluate and continuously adapt innovations that meet their expectations.

Calculation of the nitrogen nutrition index for oilseed rape: updating the critical nitrogen content curve (results of the Inn Colza project)
February 10, 2022
The nitrogen nutrition index (NNI) is a key agronomic variable for determining the nitrogen supply status of a crop at a given point in its growing season. It is calculated as the ratio between the measured nitrogen content of the above-ground parts of the plants and the reference (so-called "critical") nitrogen content for the level of dry biomass reached by the crop.
The critical nitrogen curve for oilseed rape used today is based on work that is almost 25 years old. It was necessary to update it with the most recent data available.
Speakers : Sébastien GERVOIS & Luc CHAMPOLIVIER
What is the status of Fileg, the project to create a legume industry in Occitania?
February 24, 2022
In order to promote legumes, Terres Inovia, together with the interprofessional organisation Terres Univia and numerous partners, is working on the creation of a sector dedicated to legumes in Occitania.
This regional and federative project, whose ambition is the creation of values (economic, social, societal, environmental...) for regional agriculture, responds in particular to the major challenges of food and agro-ecological transitions.
This regional agreement on these issues has led the project's pilots, the heads of agricultural and economic organisations and institutions to commit to phase 2 of the Fileg project, which began in 2020.
Speaker : Christophe VOGRINCIC
Demonstration of decision support tools for harvest date and seeding density for sunflower
March 10, 2022
Terres Inovia provides a series of simple technical tools to accompany you throughout the sunflower cycle. The first two presented are :
• A calculator to estimate the recommended seeding rate and adapted to each situation, in order to ensure a satisfactory stand according to the water constraints of the plot.
• Mapping to estimate the harvest period according to the sowing date and varietal precocity in order to make the right choices to secure the sunflower harvest
Speakers : Sébastien GERVOIS & Claire MARTIN MONJARET
How a seed observatory works
March 24, 2022
The seed quality observatories, organised by Terres Inovia with the support of Terres Univia, have been used since the 1990s to characterise seed collection in France. This characterisation focuses on quality criteria that are essentially physico-chemical and have a technical or economic impact on the first use or processing (market, outlets) and/or are taken into account in the transaction amounts.
The observatories allow the constitution of multiannual references over a long period on the quality of seeds obtained according to recognised and homogenous methodologies and allow the information of the operators of the sector on the supply of French seeds
They enable the materialization and identification on a large scale of agronomic and environmental effects on the quality of the seeds collected and to capture trends in quality that can generate collective technical or organizational actions
The dissemination of the results of the observatories is free and open to all on the Terres Inovia and Terres Univia websites, and we propose to (re)present the work on these observatories with a focus on the latest trends observed with the 2021 harvest data.
Speakers : Vincent JAUVION et Charlotte CANALE (Terres Univia)
Innovative agroecological practices in farmers' networks
April 21, 2022
Launched by the Regional Chamber of Agriculture of Occitania in 2018 and bringing together many actors in regional agriculture*, the AGLAE project (Farmers share Their Agroecological practices) aims to create a reference system of agroecological practices in Large Scale Crops and Livestock, qualified by experts, and based on feedback identified locally among farmers in the Occitania region. These testimonies deal with specific technical issues: how to effectively control weeds? How to regulate bio-aggressors in the plots?
The AGLAE project has been supported until the end of 2021 by funding from the Adour-Garonne Water Agency, and comprises 3 complementary components:
- The identification of innovative agroecological practices in farmers' networks, aiming at the acquisition of technical references;
- The qualification of these practices and the assessment of the risks involved in their implementation, thanks to a process involving a committee of experts;
- The large-scale dissemination of qualified practices, through fact sheets and video testimonials.
This project thus contributes to securing advice for farmers and to the agro-ecological transition of farms.
Speakers : Matthieu ABBELA & Mélanie LOBIETTI (CRA Occitanie)
Promote and develop new seed legume-based industries
May 19, 2022
The European LegValue project (2017-2021), coordinated by Terres Inovia and Terres Univia, has analysed the development dynamics of grain legumes at the territorial, national and EU levels, based on numerous case studies, in relation to market trends driven in particular by the diversity of human food outlets. The results of this project are now feeding the actions led by the Interprofession to support this development.
Speakers : Frédéric MUEL et Tiana SMADJA (Terres Univia)
A new method for characterising sunflower blight races (results of the Optimildiou project)
June 02, 2022
Sunflower blight is a disease that has been on the rise for the last 3 years. Nearly 20 races have currently been identified in France and this pathogen is once again proving to be particularly progressive.
Optimildiou is a project, essentially methodological, which aims to validate a brand new method for characterising sunflower downy mildew races, based on molecular markers. The main results will be presented during this session.
Speaker : Emmanuelle MESTRIES
The new recommended lists for rapeseed 2022
June 16, 2022
In order to optimise the choice of varieties according to the pedoclimatic context, Terres Inovia supports producers by proposing the recommended lists of rapeseed varieties for sowing in 2022.
The choice of variety is an essential agronomic lever for sustainable pest management and allows the crop to express its full potential.
To help producers make their choice, the lists recommended by Terres Inovia must meet several objectives: minimum productivity, but also lower sensitivity to phoma, lodging and elongation.
Speaker : Arnaud VAN BOXSOM
Orto-box: the toolbox that characterises sunflower varieties against cumana broomrape
June 30, 2022
The objective of the Orto-box project was to build a "toolbox" for reliable characterisation and distinction of sunflower varieties against cumana broomrape when registering varieties with the CTPS. It comprises three complementary elements:
- An official protocol for characterising and distinguishing sunflower varieties against the parasitic plant under controlled conditions.
- A set of differential lines, public and diffusible, to characterise the populations of Orobanche cumana, associated with a reference collection of different races of the parasite.
- A protocol for the maintenance and multiplication of broomrape populations in the collection.
Speaker : Christophe JESTIN
Bird damage to crops: what solutions?
September 29, 2022
Bird damage has been increasing in intensity for several years but no sufficiently effective solution is available. The only way to win is to understand the adversary: we must first study the behavior of birds to design new means of control and prevention, and find the winning combination.
Several initiatives have been launched in this regard. The new avenues explored by Terres Inovia and other actors in research and development will be presented in a synthetic way on the occasion of this Thursday of TI. To deepen the subject, a symposium organized on November 24 will review the work done and in progress.
Speaker : Christophe SAUSSE
Agroecological management of insect pests on a territorial scale: the progress of the R2D2 project
November 10, 2022
Since 2019, 10 farmers cultivating about 1300 ha on the plateaus of Burgundy are developing an agroecological pest management strategy, aiming eventually at no recourse to insecticides, based on two lines of work:
- To create environmental conditions favorable to the biological regulation of pests by their natural enemies and unfavorable to insect pests;
- Promote crop robustness through agroecological strategies to avoid and mitigate pest damage.
What are the evolutions of the ways of cultivation in the territory and the observed effects? What are the prospects for successfully doing without insecticides? A look back at some of the salient elements highlighted in a mid-term evaluation.

Optiplasm: optimizing the official evaluation of rapeseed varieties against clubroot
November 17, 2022
The cruciferous clubroot is a damaging disease for many brassicas including rapeseed. Resistant rapeseed varieties are available to combat it. A valuation of this criterion is proposed at the time of the registration of varieties in the French catalog thanks to a test under controlled conditions. GEVES, Terres Inovia and INRAE have decided to work together to optimize this official tool for rapeseed variety evaluation under controlled conditions.
Various actions have been carried out (development and production of single-spore isolates, comparison of a genetic panel tested in the field and under controlled conditions) with, in the long term, a new official evaluation tool, more efficient, which is part of the variety registration continuum between GEVES, UFS and Terres Inovia
