Incidence of Smut at Three Corn Plant Populations1
- J. N. Rutger and
- M. L. Risius2
Average smut infection of a group of 30 corn hybrids tested in 5 locations increased as plant populations were increased from 20,800 to 29,200 plants per acre. A highly significant (1% level) hybrid × population interaction for incidence of smut indicated that hybrids respond differentially to planting rates.
Although most of the hybrids were believed to be relatively tolerant to smut, highly significant hybrid differences in infection were observed. Smut infection, averaged over locations and populations, ranged from a low of 2.9% for hybrid 16 to a high of 18.3% for hybrid 26.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
