    Transgenic Bt (Bacillus thuringiensis) corn (Zea mays L.) hybrids with resistance to corn rootworm (CRW; Diabrotica spp.) or European corn borer [ECB; Ostrinia nubilalis (Hübner)] can have greater tolerance to water and nutrient stress, and thus may have higher optimum plant densities. Experiments were conducted following soybean [Glycine max (L.) Merr.] over nine site-years in Illinois to ...

  • Impact of planting date and hybrid on early growth of sweet corn

    Sweet corn (Zea mays L. var. rugosa) is a warm-weather crop that is grown in most of the United States. Normally, it is planted over an extended planting window to provide a continuous supply for the fresh market. However, this planting window exposes the crop to various stresses and weather risks. The objective of this study was to determine the effect of planting date on early growth of sweet ...

  • Planting date and cultivar effects on grain yield in dryland corn production

    Corn (Zea mays L.) production is gradually spreading into the Sudan savanna zone of West Africa where production is limited by erratic and inadequate rainfall. To increase corn production, production practices should be properly designed to minimize the effects of low precipitation and high temperatures that characterize the zone. A study, to determine the performance of late (120 d), early (90 ...

  • Hairy Vetch management for no-till organic corn production

    Rolling-crimping to control hairy vetch (Vicia villosa Roth) may make organic no-till corn (Zea mays L.) possible. This study investigated how rolling-crimping date and growth stage of the cover crop affected hairy vetch control and if a rolled-crimped hairy vetch cover crop could supply weed control for no-till corn. Hairy vetch was planted in late August and was rolled and crimped and planted ...

  • Corn belt assessment of cover crop management and preferences

    Surveying end-users about their use of technologies and preferences provides information for researchers and educators to develop relevant research and educational programs. A mail survey was sent to Corn Belt farmers during 2006 to quantify cover crop management and preferences. Results indicated that the dominant cereal cover crops in Indiana and Illinois are winter wheat (Triticum aestivum L.) ...

  • Biocontrol of aspergillus flavus and aflatoxin b1 production in corn

    Aspergillus flavus and Aspergillus parasiticus are the most important aflatoxin-producing filamentous fungi. They can occur in several plant products, like spices, cereals and oily seeds (Jelinek 1998, Pittet, 1998 and Lewellyn, 1992). Aflatoxins (AF) are secondary metabolites with a high carcinogenic potential, especially in liver tissue. In addition the aflatoxins possess an acute toxicity at ...
