| 2025-05-10 | KBS | G1 | Planting | {"John Deere 7330 Tractor","Harvest International Planter"} | Planted corn in the Main Site GLBRC G1 treatment all replications (5, 4, 3, 2, & 1). Equipment used: Planted with JD 7330 tractor and Harvest International Planter (first time using this new planter). Variety Planted: Pioneer P0306Q seed corn Seed Rate: 34,000 seeds/acre. Planting depth: 2.00 inches. Pioneer P0306Q has a relative maturity of 103 days and is Roundup ready corn 2 and liberty link tolerant. Also has above and below ground traits (herculex extra, agrisureRW, Yield gard corn borer protection). Full fungicide, Insecticide, Nematicide seed treatment. Fertilizer Applied at Planting Time (starter fertilizer): Applied 16.5-16.5-0-2.9 liquid fertilizer at 18.6 gallons/acre. Fertilizer weighed 11.25 lbs per gallon. 16.3 gals/A of 16.5-16.5-0-2.9 supplies 30.25 lbs N/A, 30.25 lbs P205/A, 5.3 lbs of sulfur per acre. Zinc was added to the starter fertilizer and supplied 0.2 lbs/A of zinc. The fertilizer was placed 2.5 inches down and 2.5 inches from the seed trench. | 6579 |
