This chapter of the North Carolina Organic Commodities Production Guide covers key management practices for organic corn production: hybrid selection, planting date, crop rotation, soil fertility and plant reproduction, and propagation.
Corn ear rot is a disease of corn caused by various types of fungi, including Fusarium spp. , Aspergillus spp. Penicillium spp., and Stenocarpella maydis (Diplodia Ear Rot). Ear rot diseases in corn are characterized by the molding and decay of corn ears. Environmental conditions, the susceptibility of the variety to disease, and previous disease populations in the field contribute to the emergence of corn ear rot and the severity of corn yield loss.
Many organic vegetable farmers are interested in producing sweet corn. Organic sweet corn can be grown in North Carolina and throughout the Southeast, but special considerations for variety selection, insect and disease control, economics, and markets must be made for it to be a profitable crop.
This corn disease information note offers information on the symptoms and management of gray leaf spot in corn production in North Carolina.
This publication discusses elevated nitrate levels in drought-stressed corn silage, which can result in harm to humans and livestock.
This publication discusses the Realistic Yield Expectations database as a resource for nitrogen fertilization rate decisionmaking. Topics include recent research and the resulting updates to the database for improved nitrogen fertilizer rates based on new yield data.
This publication summarizes the findings of a three-year study that analyzed the effects of fungicides, bio controls, and Bt hybrids on reducing mycotoxins in corn. It reviews effectiveness, application rate, and yield for each control option.
This chapter of the North Carolina Organic Commodities Production Guide discusses rolled cover crop mulches for organic corn and soybean production.
This publication discusses tillage treatments for large-seeded crops like corn and soybeans in the Piedmont region and recommends minimizing tillage based on research at the Upper Piedmont Research Station.
