The oil extracted from canola has high industrial and economic value, since it is used as edible oil and feedstock for biodiesel production. It is also the third most produced oilseed in the world. Due to the great interest on the water requirement for canola crop (Brassica napus L. var. oleifera Moench.), the present study aimed at evaluating the response in growth rate and crop development depending on the groundwater levels variation (GL) and the use of swine farming waste from biodigester (biofertilizer). The study was conducted on a set of drainage lysimeters of 200 mm nominal diameter in protected experimental area of the State University of West Paraná, Unioeste, campus Cascavel, Paraná, Brazil, in the period from April to September, 2013. The experimental design was completely randomized with six treatments of groundwater variation using biofertilizer: 0.1, 0.2, 0.3, 0.4, 0.5 and 0.6 m in triplicate. A control treatment was performed concomitantly with the same depth levels using only water, also in triplicate. The parameters evaluated included: plant height, stem diameter, dry weight of root and shoot and number of pods. Data analysis was performed using the Origin software 8.05, generating graphics and curve fitting. For the Student’s t-test, the ASSISTAT software version 7.6 beta was used for regression analysis at 5% probability of error. Statistical data showed positive effect on the growth of canola plants with increasing groundwater. Treatment using biofertilizer also showed satisfactory results in the evaluated parameters, especially the number of pods per plant when compared to the control.
