Popis: The productivity of soybeans in Brazil is affected by the low availability of phosphorus in the soil. In this direction, the objective of this study was to evaluate the performance of soybean cultivars after the application of doses of phosphorus. A completely randomized design was used in a 5 x 2 factorial scheme for an experiment installed in a greenhouse. The first factor consisted of five doses of phosphorus (0, 50, 100, 200, 300 mg dm-3 of P2O5) and the second for two soybean cultivars (M-SOY 9144RR and NS 8094RR). Aspects such as plant height and weight of grain mass per plant were evaluated. The results were subjected to analysis of variance by the F test at 1% significance and the comparison test of means by the Scott and Knott test at 1% probability. Results showed that doses of 50, 100, 200, 300 mg dm-3 de P2O5 for the plant height variable presented satisfactory results regardless of the variety. The same was observed for the variable grain weight per plant.
