Abstract
Cover crops and reduced tillage practices have been commonplace within agronomic crops for many years. The benefits of cover crops have been heavily researched and include improving soil health, increasing infiltration rates, reducing runoff and erosion. Despite these benefits, their adoption in vegetable production has been slower due to the perception that incorporating cover crops and reduced tillage causes yield reductions. Issues with weeds in these systems can also be a deterrent. Fewer herbicides are available for use in vegetable production, making tillage the primary method of weed control. Weeds are a significant threat to vegetable yields. Incorporating cover crops as a strategy for weed control may be effective at suppressing weeds within low-input agriculture. This research was conducted to determine the effect of cover crops combined with reduced-tillage on vegetable crop yield, weed abundance, and distribution and to evaluate variable fertilizers rates to overcome nitrogen sequestration by cover crops.
