Resumen

The common bean crop (Phaseolus vulgaris L.) is a vital legume worldwide due to its nutritional value and its adaptability to various regions. Its ability to fix nitrogen with symbiotic bacteria makes it an ideal choice for improving soil fertility and crop rotation. However, the increasing demand for food has led to excessive use of chemical fertilizers, leading to environmental and health problems. The present study evaluated the effect of rhizobia strains E10 and LMT-R28 on the yield of canary beans, comparing it with nitrogen fertilization and a control. The results showed that rhizobia strains had a significant effect on bean growth and yield, especially the LMT-R28 strain. Significant differences were observed in plant height, number of pods per plant, pod size, 100 seed weight, root length and yield, with superior results in the inoculated treatments compared to the control. These findings suggest that the use of native rhizobia strains can be an effective and sustainable alternative to improve agricultural productivity and reduce dependence on nitrogen fertilizers.
