Downtown Shell Knob MO Come Visit! | Did a little study this year. Twin row corn planted at 42k made 2bu per acre, 20 inch corn planted at 38k made 2bu per acre. 36inch corn planted at 20k made 14bu per acre. 30inch corn planted at 29k was inbetween but closer to 2 than 14. I don't recall but I think it was inbetween 4 and 5
All row widths had 2 ton of poultry manure, 60 pounds of dry N at planting half urea half AN, and sidedressed with 120 pounds of UAN. with Allis Chalmbers G tractor at V4. ( And incase you were wondering the Allis G had no problems going down the 20inch and twin row corn :) ) |
36vs 30 vs 20 inch row spacing corn
