They seek to maximize the yield of Andean corn

Tridge summary

Researchers from various institutions are studying to improve corn cultivation in Argentina's Northwest, where high altitude and limited scientific information challenge farmers. The research focuses on evaluating local corn varieties and developing management practices, with a survey revealing that high-altitude producers use a greater variety of local corn and face more restricted irrigation conditions. The project, funded by the International Treaty on Plant Genetic Resources for Food and Agriculture, highlights the importance of in situ conservation and integrating terrestrial and bank conservations. A study by Diego Salve shows that increasing planting density can improve corn yields at higher altitudes, despite expectations. This research aims to support producers in sustaining their productive systems, which are threatened by climate change.

Made up of different agroecological ecosystems, the Argentine Northwest (NOA) comprises a territory of around 14 million hectares ranging from 1000 to 4000 meters above sea level (masl). There, more than 60,000 peasant families cultivate and work the land. Of the most important crops in the region (corn, beans and potatoes), corn is the one that is most sensitive to low temperatures associated with increased altitude. In this sense, specialists from INTA (Salta and Pergamino, Buenos Aires), IPAF NOA, the National University of La Plata and Conicet are studying different alternatives, such as the evaluation of local varieties and the development of specific management practices for altitude conditions. In addition, they seek to strengthen the conservation of the genetic resource in situ, that is, in the territory where corn is grown. According to Mariana Ferreyra, researcher at INTA Salta, "the yield of corn in these environments is limited by the conditions of the sites where they ...
