Abstract. The common beans (Phaseolus vulgaris L.) is an important food and subsistence crops in tropical agriculture. However, beans cultivation methods can be improved in soil preparation and fertilization, for greater sustainability and cost reduction. Thus, the aim of this study was evaluating the effect of fertilizations and soil management methods on the tropical common bean`s performance. The study was conducted on three soil preparation systems (conventional, minimum and direct), combined with two fertilization systems (broadcast and furrow) in bean crops. A randomized block design was used in a 2x3 factorial scheme composed of two fertilization systems and three soil preparations with four replications. The surface or in-furrow fertilization method did not significantly affect the productive performance of the beans. The fuel consumption and CO2 emissions are influenced by the soil management system, with the lowest average in No-Till system (NT), followed by minimum cultivation (MT) and conventional preparation (CT). Soil management not affected by tractor performance due to slippage. Thus, crop yield in MT system presented the best result compared to the CT and NT. MT provided a superiority yield of 7.55% and 39.83% in relation to CT and NT, respectively.
