Resumo


Peanut crop (Arachis hypogea L.) has great food interest due to its high content of protein and oil, however, there is the need to observe its aptitude for a certain region where temperature and rainfall data provided by Instituto Nacional de Meteorologia (INMET) were used from 1961 to 2012. The production of peanut crop is highly influenced by weather conditions as well as all crops, thus this study aims at determining agroclimatic aptitude of the peanut crop in the municipalities of Campo Novo do Parecis, Cuiabá, Cáceres, Diamantino, São José do Rio Claro and Tangará da Serra all located at the state of Mato Grosso. The means of meteorological elements were ten-day calculated, totaling 36 ten-day periods for each climate variable and municipality. Based on the analysis of climate variables together to hydro and thermal crop requirements ranging from 500 to 700 mm and between 22 and 28  C, respectively, it is concluded that peanut crop is considered suitable for the conditions found in the regions, considering that the thermal requirement of all ten-day periods were within or close to the ideal range of development. Rainfall is suitable by peanut crop from 13th to 26th of ten-days.
