Abstract

The increase in vegetable production has increased due to atypical factors such as the Covid-19 pandemic, where techniques such as hydroponics gain importance for obtaining results similar to conventional production, reducing water consumption by up to 70% and managing to control environmental factors in development. of cultures. In this sense, the objective is to evaluate the effects on the production of hydroponic lettuce subjected to magnetic and electromagnetic treatment in the nutrient solution. A completely randomized design was used, with four replications. The treatments were exposure of the nutrient solution to magnetic, electromagnetic and no exposure treatment (control) over four monitoring periods 7, 14, 21 and 28 days after transplantation (DAT), with four replications. The use of magnetism and electromagnetism in the nutrient solution provides an improvement in the development, productivity and presence of algae, with magnetism having good results in biometric variables, while the concentration of nutrients had no differences throughout the development of the hydroponic lettuce culture. This study presents a technological alternative to enhance the productivity of different crops with greater tolerance to the effects of stress and lower fertilizer consumption.
