Study checks time of ripening of different cultivars of Arabic coffee in São Paulo state
Researchers from Instituto Agronômico de Campinas (IAC), São Paulo, Brazil, demonstrated that the region of Alta Mogiana, in São Paulo, has weather conditions favorable to maturation of arabic coffee. The research was published in Ciência Rural journal, v.42, n.4, of April 2012.
In order to generate maps of likely time of maturity of three different cultivars of arabica coffee, the researchers built up the growing degree-days (DD) from the date of flowering via geographic information systems (GIS). The researchers observed the cultivars in two regions of the state of São Paulo: the central west and northeast (Alta Mogiana).
The results show that the arabica coffee cultivars have different maturation times depending on the region of São Paulo where they are grown. The Midwest region had the shortest cycle for the three cultivars, anticipating maturation. This is due to low altitudes (below 600 m) and high temperatures in the region. In the northeastern state, maturation occurred in periods subsequent to May, due to its altitude above 800 m. Maturation in the last region favors the obtainment of coffee beverages with superior quality.
The research breaks new ground by addressing new information on the maturation of the phenology of the main varieties of Arabica coffee grown in Brazil. According to researcher Marcelo Bento Paes de Camargo, this knowledge presented in map form can support the identification of areas with different potential for the production of superior quality coffee drinks in state of São Paulo. The data can also assist in agricultural planning and in the advance collecting of seeds, to the formation of seedlings to the beginning of the rainy season.
According to Marcelo, there are several articles in the field of agronomy research linking climate and phenology, especially for annual crops and perennial. "This research becomes important in the current scenario that requires new knowledge of the relationship between climate and phenology of coffee, with a focus on producing quality coffee in Brazil," he concludes.
