Abstract
Abstract The evaluation was carried out on a Hagerstown silt loam soil in central Pennsylvania, near University Park, and planting was done on 22 May in continuous corn. The design was RCB with five replicates of each treatment. Plots were 20 ft long X 2 rows wide, with row spacing at 30 inches. Granular treatments were applied at planting using a Max Emerge John Deere 7000R corn planter. T-band applications were applied in 7-inch bands over the row and into the furrow, and in-furrow applications were directed into the furrow only. Furadan 4F was broadcast on 20 Jun, and cultivation for the Furadan 4F + cultivation treatment was done the same day. The Regent 80 WG treatment was applied at a rate of 2 gal water per acre as a spray directed into the furrow. Rainfall totals for the research site during the trial were: 3.03 inches (May), 4.95 inches (Jun), 5.20 inches (Jul), 5.53 inches (Aug), 12.55 inches (Sep), and 4.97 inches (Oct. Plots were rated with the Towa’ rating method on 30 Jul (5 plants/plot), and by quantifying yield on 15 Nov (total grain weight/plot). Final yields were expressed as grain acre at 15.5% moisture.
