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 two central lines indicated the usable area of the subplot.
