  • Objective: Due to the importance of bean in human consumption, vegetative development and seed yield of Negro Veracruz beans were evaluated using a nutrient solution with different magnetization times in combination with different pH levels.

    Design/Methodology/Approach: The experimental design used was completely randomized with a 46 factorial arrangement with three replications. 24 treatments of the combination of four magnetization times and six degrees of acidity of the nutrient solution were evaluated. The variables evaluated were vegetative development and yield components. The results were subjected to an analysis of variance and media separations were performed using Tukey’s test (0.05).

    Results: The magnetization and the degree of acidity of the nutrient solution significantly inf luenced the variables. The most outstanding treatments were 2 and 24 hours of magnetization in combination with pH values of 4 and 5, for most of the variables of vegetative development and evaluated yield components. The magnetization treatments of 2 h together with pH values of 4 and 5 increased height, biomass, days to f lowering, number of pods, harvest index and seed yield.

    Study Limitations/Implications: Care should be taken that exposure to the magnetic field at high intensities may produce adverse effects on growth and development.

    Findings/Conclusions: It is concluded that an appropriate combination of magnetization time and degree of acidity of the nutrient solution improves vegetative development and yield.
