APLICAÇÃO DE DIFERENTES CONCENTRAÇÕES DE BIOFERTILIZANTE LÍQUIDO TRATADO MAGNETICAMENTE PARA PRODUÇÃO DE MUDAS DE TOMATE

Abstract

The use of biofertilizers in agriculture has proven to be an effective alternative for cost reduction, sustainable waste disposal, and mitigation of exposure to fluctuations in fertilizer prices. Additionally, the quality of irrigation water is a crucial factor for the production of tomato seedlings; in this context, magnetic treatment emerges as an innovative approach to stimulate growth. The objective of this study was to evaluate the growth of tomato seedlings subjected to four concentrations of liquid biofertilizer (0; 1/30; 1/20; 1/10 v. biofertilizer/v. water) and magnetic treatment of the biofertilizer (with and without). The results indicated that the increasing concentration of liquid biofertilizer promoted a quadratic effect on height, stem diameter, shoot fresh matter and shoot dry matter. This suggests that the use of biofertilizers, especially when combined with magnetic treatment, can be a promising alternative to enhance the growth of tomato seedlings. The biofertilizer concentration between 0.050 and 0.072 (v. biofertilizer/v. water) can be considered for practical application of producers.
