Resumo:  Heart-of-palm, palm heart, or "palmito" can be considered as a non-conventional vegetable, largely consumed in Brazil and exported to more than sixty countries. Timing of heart-of-palm harvesting is a critical issue in palmito agribusiness, since it affects yield, quality and costs. A three-year field experiment was utilized to identify the correct timing for king palm heart-of-palm harvesting, from the standpoint of maximizing yield and minimizing growing period. The experimental site was located at Pariqueraçu, Vale do Ribeira, a region where palmito agribusiness has increased recently, due to adequate climatic conditions, low costs and high industry demand. Crop was grown in 2 x 0.75 m spacing, utilizing six-month old seedlings. Growth was assessed periodically by measuring plant diameter and height (from soil level to insertion of leaf spear), as well as leaf number and size. Harvest was done, from 36 to 40 months after planting date. The results showed high plant variability, a common feature in palm. In spite of genetic variability, the adequate timing for start heart-of-palm harvesting (considering plant growth rate, yield, quality and market type), was reached when palms were 80 to 115 cm (small diameter) and 200 to 300 cm tall (large diameter). The time to attain those heights varies widely among plants and growing conditions. In this experiment, harvesting could be started at 22 months after planting.
