Below are diagrams and information about the ginger field plot layouts, practices, and treatments.

Objective:  To grow wilt-free ginger in pathogen-free soil.

Location of field: SCM farm Pepeekeo S2 (above water tank) (see plot map below)

Plots:

  • Number of plots: 2
  • 20 ft. x 15 ft. = 300 sq. ft. = 0.0069 ac.
  • Three rows of 20’; each row spaced 5 ft. apart
  • Spacing of ginger: 5 ft. between rows and 8 inches within rows

Planting:

  • Planting date: April 13, 2011
  • Size of ginger seed pieces: 2-3 ounces (0.167 pounds)
  • Number of seed pieces: 30 per row x 3 rows = 90 per plot; 180 per 2 plots
  • Weight of ginger seed pieces used: 15 pounds per plot or 30 pounds per 2 plots

Fertility amendments:

  • TSP = 0-46-0; (20% P)
  • Dolomite = 98% CaCO3 equivalent
  • Pelleted chicken manure
  • 10-30-10 (prefer w/ minors)
  • 10-20-20
  • Muriate of potash

Data collection:

Harvest ginger rhizomes during January 2012, after approximately 9-10 months of growth. Obtain data on the fresh weight of ginger rhizomes in the middle row (20 feet long). Take small samples of any suspicious-looking ginger to test for presence of ginger wilt or other pathogens. Take small samples to determine moisture content. Prepare ginger rhizomes for planting in a 2nd planting cycle; use experimental area immediately above the current plots provided that no ginger wilt was found in crop.
