• Resumo:

  The nutrient uptake, the partitioning of dry matter and sweet pepper fruit yield were characterized under unheated greenhouse conditions. The experiment was carried out from March to December, and the randomized block design was used with 6 replicates and 16 treatments. Seedlings of Elisa cv. were transplanted to the field in 1 x 0.6 m spacing on April, 27th. Each treatment corresponded to a sampling time accomplished every 14 days from transplanting. At 224 days after transplanting (DAT) to the plastic house, the pepper plants presented 91 cm of height with a leaf area of 9056 cm² plant-1 and 189, 79 and 109 g plant-1 of fruit dry matter, stem and leaves, respectively, also presenting an absolute growth rate with maximum value of 4.11 g m-2 day-1. Plant growth was continuous along the plant cycle and fruits accumulated the highest amount of dry matter. Total ripened fruit yield was 51,960 kg ha-1 or 232 kg ha-1 day-1 of crop permanence in the greenhouse. Marketable fruits were represented by 92.8% of the total yield.
