Growing maize landraces in industrialized countries: from the search for seeds to the emergence of new practices and values

Marianna Fenzi

In industrialized countries, maize cultivation is mainly associated with the use of hybrid varieties and input-intensive monocultures. Despite the homogeneity of European maize landscapes, alternative models of maize production based on landraces exist. Un ...
