Several factors can interfere in the development of the soybean crop, among which we can mention the management of cultural remains and the method of applying the fertilizer. The objective of this study was to evaluate straw management equipment (knife roller, rotary mower and straw crusher) and fertilization systems (before sowing and sowing), soybean production and soil cover. The experiment was conducted in Red Latosol using a 2 x 3 factorial randomized block design with four replicates. The initial and final stand, longitudinal distribution, plant height and insertion of the first pod, number of pods per plant and number of grains per pod, mass of 100 grains and yield in addition to the percentage of soil cover and dry biomass in the soil. The straw management systems, individually, influenced the variables: stand, height of insertion of the first pod and number of pods per plant. The interaction between straw management and fertilization, whether at sowing or before sowing, did not influence soybean yield. Soil cover was higher for the treatment with a knife roller with fertilization in pre-sowing. The dry mass in the soil was higher after handling to the straw crusher in the before seeding fertilization.
