The impact of COVID-19 on alternative and local food systems and the potential for the sustainability transition: Insights from 13 countries.
(Elsevier, 2021-06-23)The COVID-19 pandemic has been a major stress test for the agri-food system. While most research has analysed the impact of the pandemic on mainstream food systems, this article examines how alternative and local food ... -
Genome-wide association analysis of agronomical and physiological traits linked to drought tolerance in a diverse potatoes (Solanum tuberosum) panel
(Wiley-Blackwell Publishing, 2021-06-12)Potatoes is often considered a drought-sensitive crop and its sustainable production is threatened due to frequent drought episodes. Drought tolerance is a complex trait of increasing importance in potatoes therefore its ... -
Assessment of the main sources of variability of soybean (Glycine max) expeller composition and quality: a field study
(International Commission of Agricultural and Biosystems Engineering, 2020-12-26)Pairs of soybean seeds and their correspondent expeller samples were collected from ten extrusion-expelling processing plants in Argentina. Seeds were analyzed for proximal composition, bulk moisture content (MC) and ... -
Caracterización del uso del silo bolsa en la provincia de Buenos Aires
(Facultad de Ciencias Agrarias, Universidad Nacional de Rosario, 2019-03-03)En Argentina existen numerosos estudios aconsejando cómo utilizar el silo bolsa, sin embargo, no se ha analizado la manera en que los productores usan realmente esta tecnología. El objetivo de este trabajo es caracterizar ... -
