Influence of planting date and row covers on yield and economic value of muskmelons

Abstract

In 1990 and 1991, earliness, yield and economic value of three sequential plantings of muskmelons were compared using black plastic soil mulch alone (NC) and in combination with clear polyethylene (PT) or spunbonded polyester (RT) row covers. Both row covers increased daytime temperatures and heat unit accumulation relative to NC treatments, with PT producing the warmest microclimate. Early growth and fruit yield were highest in PT plots followed by RT. The NC crop was slow to develop and most fruit failed to mature before first frost. Early planting increased fruit yield when row covers were used, while late planting was best in NC treatments. The increase in economic value obtained with the tunnels more than offset their cost. Key words: Muskmelon, Cucumis melo, planting date, row covers
