Improving food-system efficiency and environmental conservation using agricultural biodiversity in Busia County: a pilot study por Manjella, A., Wasike, Victor W., Borelli, Teresa, Hunter, D.

“…Much of this biodiversity, used in traditional food preparations, has the potential to provide access to key micronutrients for healthy and balanced diets and to act as an important source of community resilience to climate change and economic turbulence. Yet, low consumer awareness of the value of local biodiversity, poorly developed value chains, and negative perceptions of traditional foods have led to the disappearance of many nutrient-rich species and the shift to unhealthy diets. …”

Photoperiod and vernalization requirements in Argentinian oat genotypes por Dietz, Juan Ignacio, Da Silva, Laura Victoria, Schierenbeck, Matías, Pardi, Martín, Simón, María Rosa

“…Understanding the response to temperature, vernalization, and photoperiod provides a significant advantage for optimizing the adaptability of oat (Avena sativa) genotypes to different production areas and sowing seasons in a climate change context. For this, two experiments were carried out in the Argentinian Pampas, where nine oat genotypes were sown on six sowing dates (from June to December, <10 h to >15 h photoperiod) and three vernalization treatments (40, 20, and 0 days at 4°C). …”
