An experiment was carried out to evaluate the growth and division of treated tomato plants grown in soil covered or not with black polypropylene. The experimental design was of randomised complete blocks, in split plots and four replications. In the plots, the treatments consisted of two systems (with and without a black polypropylene TNT covering) and in the subplots, plant-sampling times of 14, 28, 42, 56, 70, 84, 98 and 112 days after transplanting (DAT). The following were evaluated: dry matter accumulation in the leaves (DML), the branches (DMB), the inflorescences (DMI), the fruits (DMFR) total dry mass (TDM), the leaf area (LA), leaf area ratio (LAR), net assimilation rate (NAR), absolute growth rate (AGR) and relative growth rate (RGR). The ground cover did not influence the DML, DMB, DMI DMFR or TDM as well as LA, LAR, NAR, AGR or RGR. The fruits behaved as preferential drain for the plant, reaching the end of the cycle with 47.77% of the total dry mass accumulation. The LA, LAR and AGR reached maximum values at 83, 27 and 73 DAT, averaging 75,835 cm² plant-1, 201.5 cm² g-1 and 14.87 g plant-1 day-1 respectively, while the RGR and NAR decreased throughout the evaluation period.
