ARC-Apopka Research Report RII-1980-12

Four inch seedlings of Tree Fern, (Asparagus virgatus) wreep nTa 'd o
Jnniary 17, 1979 under 73% shade at the Agricultural Research Center Apopka.
Twelve plants were spaced 16 inches by 1 foot in plots 3 by 5 feet. Three
levels of nitrogen were applied in combination.with 2 levels of potassium and
a constant level of phosphorus. Fertilizer was applied every 4 weeks using
ammonium nitrate, phosphoric acid and potassium chloride. Fern were harvested
April 22, July 1, and September 29, 1980.

Initial results indicate that Tree Fern should be fertilized with
1000-500-1000 pounds per acre of N-P205-K20 per year, or 80-40-80 pounds per
acre of N-P205-K20 per month. Yield after initial cut is equivalent to
approximately 10 fronds per square foot per year when grown under 73% shade
at the high fertilizer levels.
