Conservation tillage is an effective sustainable production system for vegetables. No-till planters and transplanters and strip-till cultivation equipment are presently available for most vegetables. Lack of weed management tools (herbicides, cultivators, etc.) continues to be the cultural practice that limits adaptability of some vegetables to conservation tillage systems. Nitrogen management can be critical when grass winter cover crops are used as a surface residue. Advantages of using conservation tillage include soil and water conservation, improved soil chemical properties, reduction in irrigation requirements, reduced labor requirements, and greater nutrient recycling. However, disadvantages may include lower soil temperatures, which can affect maturity date; higher chemical input (desiccants and post-emergence herbicides); potential pest carryover in residues; and enhancement of some diseases.

Organic and conventional fruits and vegetables contain compounds with important human health promoting effects. Whether fruits and vegetables grown via organic versus conventional production systems are superior in taste and nutrition, at present, is difficult to say with complete certainty. To ascertain possible quality differences and develop a definitive data base, direct comparative studies of organic vs. conventional produce requires following rigorous guidelines which includes 1) appropriate study approaches (retail market vs. farm vs. research center studies), and 2) standardized preharvest production site, harvest procedural, postharvest handling, and analytical methodology constraints.
