Abstract

Excluding insects by covering rows of cantaloupe or summer squash with spunbond polypropylene material offers an alternative to insecticide application. Labor for manually establishing row covers may be reduced if a satisfactory system to mechanize row cover establishment can be developed. Field tests of a commercial semi-mechanized implement were conducted in medium and coarse soils at two different moisture contents to examine the machine’s ability to successfully insert supporting hoops and lay fabric row cover in these soil conditions. This study also helped identify specific facets which require modification to improve machine performance.

Soil bin tests indicated adequate soil force to resist hoops springing out of the ground with minimal insertion. Subsequent implement operations in the field indicated that other machine adjustment features were affecting success of wire insertion after depth wheels were set to at least 13 cm insertion. Success of wire insertion generally increased with experience operating the implement. Hoops inserted deeper into coarse soil, but were more likely to lean in the direction of the row. Covering hoops with spunbond polypropylene material was successful if hoop placement was successful.
