Field experiments were conducted to determine dry matter yield of shoot of upland rice (Oryza sativa L.), common bean (Phaseolus vulgaris L.), corn (Zea mays L.), and soybean (Glycine max L. Merrill) grown in rotation on an Oxisol. Plant samples were taken at 19, 43, 68, 90, 102, and 130 days after sowing of rice; 15, 29, 43, 62, 84, and 96 days after sowing of common bean; 18, 35, 53, 69, 84, and 119 days after sowing of corn and 27. 41, 62, 82, 120, and 158 days after sowing of soybean. Dry matter production of four crops was significantly (P&lt0.01) influenced during the crop growth cycle. Dry matter production differ among crop species and it was in the order of corn &gt upland rice &gt soybean &gt common bean. Concentrations or all the nutrients decreased with the advancement of plant age except few exceptions. However, the magnitude of decrease varied with the crop species and nutrients. The nutrient concentrations values at different growth stages can be useful in interpretation of plant tissue analysis results of rice, common bean. corn, and soybean.  aArroz  aFeijão  aNutriente  aOryza Sativa  aOxisol  aPhaseolus Vulgaris  aSoja  aRotação  tCommunications in Soil Science and Plant Analysisgv. 35, n. 7/8, p. 961-974, Apr. 2004.
