  • [hal-04982344] CH10 -Advances in the reduction of herbicide use in Conservation Agriculture systems

    Conservation agriculture (CA) appears as a promising agricultural pathway to achieve multiperformance but is currently questioned due to its reliance on herbicides for weed management, especially glyphosate.<p>One limit in the development of CA-based agroecological cropping system less reliant on herbicide use is the strict definition of CA based on technical means (i.e. the three principles) rather than targeted objectives. In this chapter, we mobilize research carried out on experimental stations (e.g. CA-SYS platform) and farmer networks (e.g. French DEPHY-farm network) to synthesize knowledge on how pesticide-free no-till agriculture could be achieved. We provide insights on the multiperformance of pesticide-free and nature-based CA systems compared to reference CA systems. Designing cover crops to ensure growth in a context of unpredictable weather conditions and facilitate mechanical termination, and ensuring crop establishment in absence of tillage and herbicides represent major research avenues for the development of pesticide-free CA systems.</p>

  • [hal-04732768] Crop diversity used in branded products with focus on legume species worldwide

    Food diversity is a challenging issue for sustainable agrifood systems. Diets are increasingly dependent on branded packaged foods. Therefore, the crop diversity offered in the food market through these products is of particular importance. We scrutinize this diversity for some crops under great societal challenge: pulses. Based on the product launches referenced in the Mintel database over the last decade, we compare the food products containing pulse crops with those containing another legume-soy. From the 350,000 products analyzed, our results show that soy is mainly used but reveal some progress in the use of pulse species, particularly in Europe. The position of the examined species in the list of ingredients and in the product description allows us to assess its importance. The text-mining methods used usefully enable the monitoring of crop usage in the food market. We discuss several perspectives, notably how to deepen these results regarding consumer choices.

  • [hal-04654455] Interspecies diversity in morphological responses to water stress: study on a panel of weed and crop species.

    Climate change modifies the dynamics and the quantity of plant water supply, and plant morphological response to environmental factors plays a key role in crop-weed interactions. This study investigated the interspecies diversity related to the morphological responses of annual herbaceous species to water stress. Key morphological traits were measured at two growth stages on five weed and two crop (soft wheat, rapeseed) species grown on a gradient of water availability in a greenhouse experiment. For each trait, response curves to water stress were defined, and their parameters were used to quantify interspecies diversity. Generic morphological response patterns were identified across all species and plant stages. Water stress reduced leaf area per unit leaf biomass (SLA, lowering water demand) and increased the ratio of plant height to aboveground biomass for all species (HBR, keeping access to light). In most situations, the ratio of root biomass over total biomass (RBR) increased (improving water uptake). Variability in parameter values of morphological traits was primarily explained by the species, followed by growth stage. Geranium dissectum L. and Abutilon theophrasti Medik. were the most responsive species to water stress, especially at the flowering stage, with strong RBR and HBR increase and slight SLA decrease. Species differences were not related to clade (monocotyledonous/dicotyledonous) nor status (weed/crop), despite a near-significant clade effect on allocation of aboveground biomass, with grass species allocating more biomass to stems (vs leaves), while no general tendency was observed in broadleaved species. These findings provide new insights on comparative ecology of weed and crop species response to water limitation, and more research is expected to cover a wider range of weed and crop species.

  • [hal-04639611] Optimal species proportions, traits and sowing patterns for agroecological weed management in legume-cereal intercrops

    Intercropping, i.e., growing several species in the same field for a major part of their growing periods, often improves yield and weed control, but their performance greatly varies across situations. The aim of this study was to evaluate the effects of bi-species legume–cereal intercrops on weed dynamics and their impact on crop production, in the absence of nitrogen or water stress, via simulations with FLORSYS. This individual-based 3D model simulates daily crop–weed seed and plant dynamics over the years, from cropping system and pedoclimate, focusing on competition for light. The study tested seven species proportions in two species mixtures (wheat–faba bean and barley–pea) and nine spatial sowing patterns in three species mixtures (triticale–faba bean, wheat–faba bean, wheat–pea), in both cases comparing the intercrops with the corresponding sole crops (controls). Intercrops and controls were inserted into rotations and simulated over 30 years and repeated with 10 climate scenarios from South-Western France, either with or without weeds. The simulations showed that: (1) the intercrops that best controlled weeds were barley–pea and triticale–faba bean, (2) the spatial pattern alternating one cereal row with one legume row as well as the 67 %-cereal–33 %-legume and 100 %-cereal–50 %-legume species proportions were those that maximised yields and minimised losses due to weeds, (3) the weed biomass in intercrop was greater than or equal to that of the sole cereal, and less than that of the sole legume, and (4) legumes benefitted more from intercropping than cereals because cereals are more competitive against weeds. Intercrop yield was best when combining species with contrasting shading responses (etiolated with stockier plants, leafy with stemmier plants) but early and good plant emergence was essential, particularly for weed suppression.
