The objective of this work was to avaliate the viability of canola (Brassica napus L.) in different municipalities in the Alto Paranapanema Basin through crop modelling. We used daily meteorological data of maximum and minimum temperatures (ºC), rainfall (mm) and global radiation (MJ.m-2.D-1) of ten municipalities in the region between 2009 to 2019 and, later, introduced in the DSSAT plataform to the determination of attainable productivity. Ten dates of sowing were simulated, spaced fifteen days, from February 15 to June 30, with the objective to understand the right sowing window of the canola in the Alto Paranapanema Basin. Finally, data was spatialised with Quantum Gis software (QGis 3.18). Even though these simulations are far from productivity indices of traditional countries in canola production, as Canada, at the national level the region can be an exponent of production, with average attainable productivity on the best sowing dates, between April 15 to 15 June, of 1.492,85 Kg.ha¹ and average standard deviation of 139,60. This shows the potential of canola in the Alto Paranapanema Basin region, and should therefore have investments to quantify and, subsequently, increase agricultural productivity.
