Changes in sowing date can strongly affect plants development ( Hay, 1986 ). Sowing dates can be manipulated to avoid the periods of greatest risk from pests, weeds, and diseases and hence increase yield of the crop ( Harper, 1999 ). Many

supplying the northern United States ( USDA, 2017b ). In Florida, cabbage is typically grown without a plastic mulch and as a result, weeds are a significant problem in most fields. Weed competition may reduce cabbage growth, quality, and yield by competing

summer weeds can be problematic in fallow fields. Cover cropping can provide effective weed control, but the practice must be simple to implement. In the northeastern United States, there are few options available fitting the requirement for a rapid

in squash production, any uncontrolled weeds can cause serious yield reductions ( Webber et al., 2010 ). In general, there are limited options for control of annual broadleaf weeds in summer squash and both organic and conventional producers would
