  abstract = {{I}n the current setting, marked by the major challenges of growing food demand and climate change impacts, the ability of sub-{S}aharan agriculture to meet population needs depends on the resilience and adaptation capacity of this system. {U}sing agro-biodiversity to promote agricultural sustainability is a strategy that has garnered much attention lately. {R}esearch suggests that mixing species or varieties within crop fields could increase the yield and/or stability. {T}his mixing is also geared towards the conservation of crop diversity while ensuring that the various associated products and services will be available at the farm level. {F}ew recent research studies have highlighted the benefits of varietal mixtures for {A}frica. {T}his lack of research is a concern, given that this continent is considered to be highly vulnerable to climate change. {T}his study was carried out to test whether plots with varietal mixtures would outperform monovarietal plots in terms of yield and pathogen regulation under smallholder farm -ing conditions in {S}enegal. {T}ogether with farmers, we conducted 30 experiments in which mixtures of early-and late-flowering pearl millet landraces were grown in these farmers' fields, while monitoring their low input management. {W}e noted a significant positive effect of varietal mixtures on grain yield (mean gain of 63 +/- 31.5 kg ha(-1) for mixture plots, p = 0.046) with a relative yield total ({RYT}) averaging 1.87 +/- 0.94. {B}oth early-and late-flowering landraces benefited from mixtures, with a greater impact on late -flowering landraces. {H}igher fertility in terms of the seed number, percentage of fertile tillers and number of panicles per tiller, was documented in mixture plots. {W}e did not find a significant effect of mixture on fodder, striga or weed infestation. {I}n water and nutrient resource limiting conditions, such as in {S}ahelian agroecosystems, growing mixtures of early-and late -flowering landraces appeared to be an efficient way to increase productivity while ensuring agrobiodiversity conservation. {P}er-haps even more importantly, mixtures allowed farmers to harvest multiple products with different uses in an agrosocioecosys-tem context with constantly increasing land pressure.},
