Colombia: Potato crops are most productive in mid-altitudes

Tridge summary

A study by Pedro Lizarazo, a Master in Agricultural Sciences from the National University of Colombia (UNAL), has found that the growth, development, productivity, and cultivation cycles of five varieties of Creole potato are influenced by altitude and temperature. The study, conducted in the municipalities of Sibaté and Granada, Cundinamarca, found that higher altitudes increase cultivation cycles and favor the growth of the tuber, while lower temperatures favor leaf growth but decrease biomass. This research, conducted in an altitudinal range to understand the response of potatoes to changes in altitude and temperature, could help producers select cultivars based on their performance at different altitudes and provide insights into the species' susceptibility to climate change. The study included five diploid cultivars from the Phureja Group, one of which, Ocarina, develops more uniformly sized potatoes, a characteristic valued in the precooked potato industry.

An investigation carried out by Pedro Lizarazo, Master in Agricultural Sciences from the National University of Colombia (UNAL) highlights that variables such as altitude and temperature influence the development, growth, productivity and cultivation cycles of five varieties of Creole potato. : Dorada, Ocarina, Paola, Violeta and Criolla Colombia, the most planted in the country. As revealed by the UNAL News Agency, in terms of development, the study found that a higher altitude increased the cultivation cycles, that is, the potatoes lasted longer to be harvested, although the thermal time did not vary between altitudes. It was also evidenced that cultivars present a difference in the duration of this crop cycle, such as the fact that not all creole potatoes are harvested at the same time. There are early varieties such as Criolla Colombia, intermediate varieties such as Ocarina and Dorada, and late varieties such as Paola and Violeta. The study also reveals that, in terms of ...
