Hydramulch for Muskmelon and Bell Pepper Crop Production Systems

Abstract

Abstract Hydramulch is an experimental biodegradable mulch material comprising cotton by-products, newspaper, gypsum, and a proprietary adhesive. Three formulations of hydramulch were evaluated for potential use as a more sustainable alternative to polyethylene mulch for vegetable production at Loxahatchee in southeastern Florida and at Gainesville in north central Florida. Two crops with differing shoot architecture were selected to evaluate canopy effects on weed suppression and the persistence of hydramulch. Less cracking and wind removal of hydramulch occurred with muskmelon (Cucumis melo L) than with bell pepper (Capsicum annuum L.) and with 4-mm-thick hydramulch compared with 2-mm-thick material. Hydramulch suppressed broadleaf weeds and grasses, but was readily penetrated by purple nutsedge (Cyperus rotundas L.). Muskmelon and bell pepper shoot growth was significantly lower with hydramulch compared with polyethylene mulch. Marketable yield of muskmelon with hydramulch at Loxahatchee and Gainesvill...
