EFEITO DA APLICAÇÃO DE DIFERENTES DOSES DE NITROGÊNIO E DE ÁGUA TRATADA MAGNÉTICAMENTE NO FEIJOEIRO

Abstract

Rational use of nitrogen fertilizers is essential for the sustainability of agricultural systems, contributing to both increased profitability and conservation of natural resources. This study aimed to evaluate the effect of different nitrogen doses and the application of magnetic treatment in irrigation water on the agronomic performance of common beans, cv. Pérola. The experiment was conducted in a factorial design, using four nitrogen doses (0, 70, 140 and 210 kg N ha⁻¹, in the form of urea) and two types of water (with and without magnetic treatment). The results indicated that the range of 103 to 118 kg N ha⁻¹ was the most efficient to the growth and development of common beans. Additionally, the use of magnetically treated water favored the increase growth, productivity and water use efficiency of the bean, regardless of the nitrogen dose applied, indicating the absence of significant interaction between the factors. These results demonstrate the potential of magnetic water treatment as a low-cost complementary technology to increase production efficiency.
