In recent times, the use of magnetic fields has been used to stimulate germination processes in vegetables seeds, without deepening in their interaction with the variables of growth, development and productivity of these. In this regard, this research characterized the effect of induced electromagnetic fields on the production and composition of the biomass of plants of Brassica napus L.; It is noteworthy that electromagnetic fields are generated from moving electrical charges, and the Tesla is the magnetic induction unit (or magnetic flux density) defined by the International System of Units (SI). Likewise, for the induction process of electromagnetic fields, coils were used, which with the help of a power source kept the variables of volts (V) and amps (A) fixed in time, thus guaranteeing the constant intensity of the field generated. A 3 x 4 bifactorial experimental design was used, where 3 are the field intensities and 4 the exposure times to be evaluated. In this context, biomass yield, growth and development characteristics, as well as bromatological characteristics of biomass were determined. For the study of these effects, a statistical analysis was performed using the Statgraphics 5.1 PLUS software, performing an analysis of ANOVA with 95% confidence to establish if there are significant differences between the treatments, as well as a multiple range test. In consequence of the experimental process, the results show a significant increase in the variables studied, mainly in biomass and synthesis of photosynthetic pigments at longer exposure times and lower intensities. Further, the variables studied for the growth and development of the plants of B. napus L.; confirming this way, a direct stimulation of these processes.
