“…Such cultivar mixtures that increase grain yield are easily transferable to the low‐input management systems common throughout most Asian and African crop systems (Teng et al ., ; Nankya et al ., ). The effects of cultivar mixtures on grain yield have been attributed to genetic diversity (Smithson & Lenne, ; Casagrande et al ., ), but have never been linked to kin recognition among crop cultivars. In sharp contrast to the effects of genetic diversity, kin recognition requires the homogeneity of genetic background with less diversity among co‐occurring crop cultivars.…”

Kin recognition in rice (Oryza sativa) lines

Kin recognition is an important mediator of interactions within individuals of a species. Despite increasing evidence of kin recognition in natural plant populations, relatively little is known about kin recognition in crop species where numerous cultivars have been generated by artificial selection. We identified rice (Oryza sativa) cultivars with the ability for kin recognition from two sets of indica-inbred and indica-hybrid lines at different levels of genetic relatedness. We then assessed this ability among kin and nonkin and tested potential mechanisms in a series of controlled experiments and field trails. Rice cultivars with the ability for kin recognition were capable of detecting the presence of kin and nonkin and responded to them by altering root behavior and biomass allocation, particularly for grain yield. Furthermore, we assessed the role of root exudates and found a root-secreted nitrogen-rich allantoin component to be responsible for kin recognition in rice lines. Kin recognition in rice lines mediated by root exudates occurs in a cultivar-dependent manner. Rice cultivars with the ability for kin recognition may increase grain yield in the presence of kin. Such an improvement of grain yield by kin recognition of cultivar mixtures offers many implications and applications in rice production.

Weed Management in the Transition to Conservation Agriculture: Farmers’ Response

et al. 2020

Recently adopted in France, conservation agriculture still faces some challenges to its adoption, particularly weed management. To highlight the weed management practices used by farmers in conservation agriculture and the changes induced by its adoption, a large sample of 425 French farmers were invited to complete an online survey. Weed management practices used by farmers were requested for three periods: before adoption, during the first years of conservation agriculture (one to two years after adoption), and when the agricultural system is considered “mastered” by the farmer. The use of each farming practice was firstly studied independently for each period. Then, a multiple correspondence analysis followed by a hierarchical ascendant classification resulted in groups of farmers with different combinations of practices for each period. Finally, the groups of farmers were followed through the periods. Results showed that changes in weed management done according to farmers when adopting and mastering conservation agriculture are multiple and vary according to farmers and their previous weed management. Although some similar choices were identified, some farmers’ trajectories, especially those with a prior combination driven by either a soil disturbance strategy or a crop competitiveness strategy, are difficult to identify when adopting conservation agriculture. Upon mastering the agricultural system, farmers’ choices become more apparent.

“…Research indicates that farmers might prefer closed questions to open-ended questions [48], that the length of the survey might influence their willingness to answer the open questions [49] and that alternatives to written communication, such as video, are acknowledged as an efficient way to foster learning for farmers; for example, [50]. This supports the observation that farmers might be reluctant to formulate answers in written form, and might be less willing to spend a lot of time on filling in surveys.…”

During farming demonstrations, peer-to-peer learning is known to be more effective than technology transfer when encouraging farmers to consider adopting more sustainable farming practices. Interactive knowledge creation has the potential to create a stimulating peer-learning environment focusing on the use of hands-on activities, knowledge scaffolding, discussions and negotiation. This study investigated how insight can be gained about the interactive knowledge creation that occurs during farming demonstrations by monitoring and evaluating a diverse sample of farming demonstrations in Belgium, Spain and Denmark via surveys and observations originally designed for the AgriDemo-F2F project. The study found that the selected monitoring tools provided insight about how participants experienced specific interactive knowledge creation. However, several stumbling blocks were also identified in using the proposed tools to monitor these learning processes, including the monitoring of abstract concepts and the reluctance among farmers to respond to self-administered open-ended survey questions. Based on these learning points, several proposals were made to improve the monitoring process of interactive knowledge creation. This study confirms that the improved understanding of learning practices and their impact on actual change presents a challenge, but it is essential if the adoption of sustainable farming practices is to be increased.
