Abstract

INTRODUCTION Common bean (Phaseolus vulgaris L.) has a great importance as a food crop worldwide and Brazil has a production about 3.29 million tons (FAO, 2014). Nitrogen (N) is the nutrient most absorbed and extracted by common bean and its use has a significant influence on yield. Due to the high cost of nitrogen fertilizers and the losses of this nutrient in the soil, which contributes to environmental pollution, it is of great interest to search for techniques that can maximize its efficiency. Although bean plants have the capacity to establish mutual symbiosis with bacteria, biotic and abiotic factors can act to reduce the efficiency of this relationship. This study aimed at evaluating the efficiency of inoculation practice with rhizobia and doses of nitrogen on production components of common bean.
