Three experiments in 1976 and one in 1977 were conducted in three Indiana soils: Tracy sandy loam, Chalmers silty clay loam, and Bedford silt loam, to study the responses of six corn inbreds (A619, A632, B14AHT, B37, B73, and OH43) to various herbicidal treatments under field conditions. several factors: corn inbreds, herbicidal rates, soil types, soil temperatures and others, influenced the responses of corn inbreds to herbicidal treatments. Experiments were carried out under greenhouse conditions to clarify the responses of corn inbreds to several factors and their interactions. Results obtained from field and greenhouse experiments allowed many important observations concerning the responses of corn inbreds to various herbicidal treatments. Experiments carried out on Chalmers silty caly loam soil showed that stands of strains A632, B37, and B14AHT were most affected by EPTC 9PPI) at 6.72 followed by choramben at 6.72 kg/ha. Best results were obtained by butylate at 6.72, followed by cyanazine at 6.72 kg/ha. Chloramben, at 6.72 and 4.48 kg/ha caused stunting on the strains A632 and B14aht respectively. Dicamba at 1.68 kg/ha caused stunting in B37 and A619. In general, dry and fresh weights were worst affected by cyanazine + X-77 at 4.48 + 0.5% v/v/, and dicamba at 1.68 kg/ha respectively. The best results were obtained with atrazine at 6.72 kg/ha. Penoxalin at 6.72 kg/ha caused a 66, 71, and 50% stand reduction in strain A632, B37 respectively when applied on a Bedford silt loam soil. EPTC at 10.08 (...).
