Within 90 days after micropropagation, pineapple (Ananas
comosus L. Merril) cv. Vitória seedlings were transferred from trays
to black polyethylene plastic bags containing sand as substrate,
with 800 gm-3 of simple superphosphate. They were acclimated for
six months and, during this period, irrigated twice a week with water
with an electrical conductivity of 0.44 dS m-1. Transplantation was
performed in April 2009; the plants were arranged in double rows,
spaced 0.90 × 0.40 × 0.30 m, with an area of 38.4 m wide and 88.0
m long, totaling 14,080 plants in 0.348 ha. Each plot consisted of
four subplots, with four double rows with 11 plants per row, and the
