In the last years the sorghum production in Brazil has increased so much, as consequence of the expansion of the planted area and productivity increments. However, studies of the organic manuring on the development of the culture are still incipient. In that way, it was aimed at to evaluate the effect of the applied organic manuring in the planting furrow in the development of plants of Sorghum bicolor. The experiment was droven in randomized blocks design, with six repetitions, being the hybrid of grain sorghum A9735R submitted to eight treatments: 0, 10, 20, 30, 40, 50 and 60 t ha-¹ of organic fertilizer applied in the planting furrow and 500 kg ha-1 of the formulation 04-14-08 + Zn. The concentrations of organic manuring in the planting furrow provided differences among the treatments. Being observed that you plant submitted to the doses 40 to 60 t ha-¹ organic manuring presented better vegetative acting for the appraised parameters. The largest answer of growth of the stem was what received 40 t ha-¹ of organic manuring.
