FX – 39’ 9-Bar Harrow Tests

FIELD #1 RESIDUE TESTS

  • Corn Stalks were shredded from combine and chopped in the fall.
  • No-Till soybeans were planted with a Kinze planter.
  • Residue was 92% before planting.
  • Residue after planting was 74%.
  • The field was then harrowed diagonally one pass with a Pepin 9-bar harrow with the teeth set to the least aggressive position.
  • Residue after planting was back up to 90%!

PLANT POPULATION TESTS ON FIELD #2

  • Drilled in No-Till soybeans with a Great Plains drill.
  • ½ of the field was harrowed diagonally one pass with a Pepin 9-Bar harrow with the teeth set to the least aggressive position.
  • ½ of the field was not harrowed.
  • Soybean plant population tests were done with the farmer and a UW Extension Agent on August 4, 1993 using “Field Crops 27.424” publication from the University of Wisconsin from June 1993.
  • Results showed that the harrowed ½ of the field averaged 28 plants per 36” hoop, equaling 170,000 plants per acre.
  • The ½ of the field that was not harrowed averaged 19 plants per 36” hoop, equaling 115,000 plants per acre.

THIS IS APPROXIMATELY A 48% INCREASE IN PLANT POPULATION, SOLELY ATTRIBUTABLE TO HARROWING ONCE WITH A PEPIN 9-BAR HARROW!!
