Table 3 shows there was a slight yield advantage for both hybrids to 15,000 kernels per acre versus 21,000. Hybrids 3970 and 3984 compared at two different plant populations. Yields are in bushels per acre. The tested area has an average 14 inches of annual precipitation. For now, a good rule of thumb would be to drop 1,000 seeds per acre for every inch of average annual precipitation.
Many herbicides are available for use in corn.
However, in dryland no-till corn, some herbicides have limited use because of their soil incorporation requirement. Other herbicides may have limited use because of their rotational crop restrictions. Wild oats, Russian thistle and some winter annuals can be troublesome weeds in corn. Banvel herbicide controls most broadleaf weeds when applied according to label recommendations. For wild oats and grasses, Accent herbicide performs well in no-till corn.
