Loam Soil

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.

Abstract Thirteen corn rootworm granular soil insecticide treatments were evaluated on a Hagerstown silt loam soil near Rock Springs, PA, during 1992. A RCBD with 5 replications was used. Insecticides and rates were applied in-furrow or as a T-band application. Plots were 39 ft × 5 ft wide (2 rows). Treatments were applied using a Max Emerge John Deere 7000® corn planter on 20 May. T-band applications were applied in 7 inch bands over the row and into the furrow ahead of the press wheel, and in-furrow applications were directed into furrow in front of the press wheel.

Abstract Experimental plots measuring 2 rows (30-inch row spacing) by 50 ft were planted on 12 May in a Waukegan silt loam soil at the University of Minnesota Agricultural Research Station, Rosemount. Treatments were arranged in a RCBD with 4 replications. Granular insecticides were applied with a modified Noble applicator at planting, either banded ahead of the press wheel or in furrow. Postemergence (25 Jun) sidedress applications of liquid insecticides were made with a CO2-powered backpack sprayer at 20 gpa. Percent lodging was determined on 16 Aug. On 25 Aug, 5 roots from each plot were dug, washed, and rated using the Iowa 1-6 scale (with half-point increments for higher sensitivity).

Vegetative growth of lingonberries was observed on plants growing in four unsterilized, native-Alaskan substrates: coarsely-ground Lemeta peat, Fairbanks silt loam soil, a mixture of peat and silt loam soil and washed Chena very fine sandy loam soil. Following three growing seasons, plants in the peat treatment showed the greatest increase in vegetative growth as revealed by the number of new stems produced, stem length and dry weight per plant. Leaf size did not differ among substrate treatments. The leaves on plants grown in the peat substrate remained green throughout the entire experiment. The leaves of plants in all other treatments showed varying degrees of chlorosis followed by reddening and necrosis. Differences in concentration of N, P, K, Mn, Fe, Zn and Al in whole-plant tissue samples were recorded. The results indicate lingonberries should be grown in a peat substrate for maximum growth and dry matter accumulation.
