Optimum plant density for crowding stress tolerant processing sweet corn in the Upper Midwest
… to better tolerate higher plant densities (i.e., crowding stress) than their predecessors. Yield gains in processing sweet corn, however, pale in comparison to field corn. Recent studies have identified modern sweet corn hybrids with crowding stress tolerance (CST); however, such hybrids appear to …

A comparison of virginiamycin and a lactobacillus probiotic as feed additives for swine and the effects of virginiamycin supplementation and crowding stress on swine performance
Two experiments were conducted to compare the feedlot performance of swine fed diets containing a commercially available lactobacillus probiotic and virginiamycin, a gram-positive antibiotic (experiment I) and to evaluate the feedlot performance of starter and grower-finisher swine housed under …

Agronomic and marker-assisted breeding strategies for improving nitrogen use efficiency in maize
… merits of important agronomic factors (e.g. N stress tolerance, yield response to N fertilizer, crowding stress tolerance, and yield response to narrower row spacing) to maize yield, and iv) evaluate the importance of hybrid characterization for agronomic traits to obtain maximum maize yield …
