Abstract The test plots were planted on 17 May. Seven inch banded (P/TB) and infurrow (P/TF) planting time treatments were applied with a cone-belt distributer mounted on a John Deere Maxemerge equipped with incorporation tines. Cultivation treatments (C/TB) were applied over the row on 22 Jun with the cone-belt distributer mounted on a hand-powered bicycle wheel applicator. The entire plot was cultivated immediately after application of the 22 Jun treatments by a tractor mounted cultivator. The seeding rate was 19,000 seeds/ acre on 30 inch rows. Soil type was silt loam (OM >3%, pH 6.5). Previous crop was late planted corn planted as a trap crop. The field was disked twice prior to planting. Preplant anhydrous ammonia was applied at the rate of 80 lb per acre prior to planting. Approximately 20% corn stalk residue was remaining after field preparation. The experimental design was a RCB with 4 replications, each treatment a single row 47 ft long. Five randomly selected roots from each replication were rated on the Iowa State 1-6 scale (1, no damage; 6, 3 or more nodes pruned to within 1/2 inch of the stalk). The roots were dug and rated on 24, 25, and 26 Jul. Topsoil and subsoil moisture was at field capacity at planting time.

Randomized Complete Block Design

Abstract Three studies were conducted at 3 SD sites (Delmont, Garretson, and Sinai) to evaluate insecticide application rates and techniques (hand and in-furrow) for control of NCR and WCR larvae. A randomized complete block design with 4 replications was used in these studies. Individual treatment plots were single 15.25 m long rows spaced 96.5 cm apart. Insecticide granules were applied with modified, ground-driven Noble metering units mounted on a specially-adapted Kinze 4-row corn planter. Metering units were calibrated on the planter prior to insecticide applications. Banded treatments were applied in an 18 cm swath in front of the furrow-closing wheels, and incorporated by the wheels and drag chains. In-furrow applications consisted of directing granules immediately between double disk furrow openers. Corn was seeded at 23,000 kernels per acre at all locations. Five roots per replicate were dug for each treatment. Roots were then washed, examined for feeding damage, and rated using the Iowa 1 to 6 scale.
