Sustainable Vegetable Production in Rural Mississippi

Sustainable Vegetable Production in Rural Mississippi

Summary

Effect of cropping systems (conventional, transitional, and organic) on sweet potato, tomatoes, bell pepper, and collar green growth and yield were conducted on Mclaurin loam and Memphis silt loam soils. Findings indicated that cropping system did not influence plant growth. Marketable yield for sweet potato, bell pepper, and tomatoes were higher for conventional cropping system while there was no yield difference on collard green due to the cropping system. Although yield were higher due to conventional cropping system, yield from the companion herbs when considered, overall yields from transitional and organic cropping systems will be compatible to conventional cropping system.

Objectives/Performance Targets

• To determine the growth, yield potential, and nutritive quality of fresh vegetable crops grown in a sustainable farming system.

  To determine the effect of sustainable crop production practices on the soil physical and chemical properties and water quality.

  To determine the input requirements, costs, and returns for vegetables produced in a low-input sustainable farming system, and compare these costs and returns with those conventionally grown.

Accomplishments/Milestones

Data from the growth components and harvest have been analyzed. Cover cropping (hairy vetch) has been planted. Surveys from the counties are partially completed. Also to be completed, are the results on soil and water qualities, as well as economic impact of the cropping systems.

Impacts and Contributions/Outcomes

Many farmers and extension personnel indicated their willingness to consider sustainable production of these crops. They admit that the plots are true learning laboratories for them. The on-campus plot was selected for visit by the year 2000 Field Day participants at Alcorn State University.
