Application of fumigant chemicals (labeled for injection) can be done using a drip irrigation

system if this system is already present.

 A second crop can be planted by either direct seeding or transplants. Seeding can be

accomplished by hand, however there are several machines available that can cut a hole in the

plastic and install the seed or plug-mix seed combination. Transplants can be installed via hand

or machine (Hochmuth, 1992).

 The use of a double-cropping system often requires the application of additional fertilizers

for the second crop. There are several methods that can provide supplemental fertilizers such

as cutting holes in the plastic to apply either liquid or dry fertilizers, applying fertilizers via

irrigation (e.g., drip system) or using a liquid injection wheel (Hochmuth, 1992).

 A double cropping system of pepper and cucumber production in Palm Beach County,

Florida is common. The pepper crop is considered the primary crop and is generally produced

using full-bed plastic mulch with seepage irrigation. This system generally requires that all soil

additives such as fumigants and fertilizers be added prior to application of plastic mulch. If the

plastic mulch from the first crop is in satisfactory condition, it is often re-used for a second crop

of cucumbers. It should be recognized that methyl bromide is not reapplied to the second crop.

The advantages of planting a second crop are that it (a) helps provide additional returns to fixed

costs beyond the variable cost of producing the second crop (e.g., land rent) and (b) re-uses

plastic mulch and other inputs (i.e., fumigant fertilizers, chemicals, and irrigation systems) that

would otherwise need to be applied if not present from the first crop.
