Abstract


The objective of the present work was to define the dose of N in the necessary cover to the greater development of the cultivated Vanda cultivar. Five treatments, doses of Napplied in a cover (0, 30, 60, 90 and 120 kg ha-1)and four replicates, were given in equal dosesat 10, 20, 30 days after transplantation (DAT). Harvest was carried out at 60 DAT where they evaluated: leaf number, plant height, leaf width, leaf length, plant width, stem diameter and total productivity. The 98.5 kg ha-1dose of N in cover fertilization provided a better development in field cultivated lettuce.
