growing season (Olson and Sherman, No Date). Irrigation can be supplied via overhead or

seepage system.

 Squash is also planted as a second crop in a double cropping system following either a

tomato or pepper crop. The double cropping system may use the full-bed mulch system

requiring the use of plastic in conjunction with methyl bromide (Hochmuth, 1993). Methyl

bromide is not registered for use in squash production, however, when squash is planted as a

second crop following tomato or pepper, it can benefit from the residual effects of methyl

bromide from the initial application for the first crop.

 The following is a description of a sequence of operations that may occur during the

installation of the full-bed mulch system. The field should be plowed and checked for leveling,

especially in areas where seepage irrigation is to be used. Soil requirements are tested, and soil

amendments are applied, such as lime for adjustment of pH. Disking may be required to

prepare the field for planting. A bed disc or disc hiller can then be used to shape the beds. A

bed press may follow to ensure good contact between the surface of the bed and the plastic. All

chemical and fertilizer requirements are applied prior to installation of the plastic. After

completed harvest of first crop (such as tomato or pepper), an application of a herbicide, such

as paraquat, can be used to kill any remaining vines. A cutter bar or mower may then be used

to remove any remaining debris. Squash may then be direct seeded into the same bed.

Additional application of fertilizer, such as nitrogen (N) and potassium (K), may be required and

can be injected via an injection wheel or drip system if the drip system is already in place.

Irrigation requirements can be met by the use of seepage, drip, or overhead irrigation.
