| Sumario: | We conducted this experiment in a greenhouse at the Universidade Federal Rural Semiarido (UFERSA)
with the aim of evaluating the effect of pine seedlings under doses of ammonium sulfate. We tested five doses of
nitrogen fertilizer (0, 800, 1600, 2400 and 3200 mg dm -3
de N), tends as source the ammonium sulfate. The
experimental design was a randomized complete block with four replications and 10 plants per plot. Characteristics
were evaluated: number of leaves, shoot length, diameter, length of root, root dry matter, shoot dry matter, total dry
matter and dry matter weight of shoot and root dry matter for the production of apple seedlings in the Mossoro city
(Brazil, State of Rio Grande do Norte), as recommended maximum dose, 2000 mg dm-3
de N, tends as source the
ammonium sulfate, applied to the substrate. |
