Previous research suggests that reducing row spacings increased grain sorghum's [Sorghum bicolor (L.) Moench.] yield potential. However, most of this research was conducted in environments with lower yield potentials than currently found in northeast

Field studies were conducted to determine the effect of soil pH ranging from 5.1 to 7.1 on imazaquin persistence on a Grundy silty clay loam (2.8% OM). Imazaquin residues were equivalent at pH 5.5 or higher but persisted longer at pH 5.1. Corn shoot

Response of soybean [Glycine max (L.) Merr.] to changes in row spacing and seeding rate have been variable. Some researchers have reported grain yields to be higher with the use of narrow row spacings. Other investigators have found that wide row spa

Sulfur deficiencies have been identified throughout the central USA with increasing frequency in recent years, yet little work has been reported on S needs of perennial cool-season forage grasses. Field studies were initiated on established smooth br
