Abstract or Summary
  • No-till pasture renovation can increase the quality and forage yield of underproductive pastures. Decreased erosion, lower costs, and less lost grazing time are advantages of no-till renovation compared to conventional renovation. Unwanted vegetation is first controlled with herbicides to decrease competition for introduced orchardgrass. Two field trials were conducted using a split-plot design to compare three seeding methods and two herbicides. An Aerway no-till drill, a Tye double disk drill, and broadcast followed by harrowing were the seeding methods. Paraquat and glyphosate were used to determine herbicide effect on vegetation control. Orchardgrass did not adequately survive at either trial site. However, where some orchardgrass did survive, vegetation control was more important than seeding method. Competition from annual grasses, many germinating after herbicides were applied, was the reason for renovation failure. Herbicide and initial growth for best control. Yield was doubled in the first harvest by the addition of fertilizer. Early spring forage production from poor pastures is usually more than adequate, so the increase from fertilizer is of marginal value unless it is stored for later use. Yield increase did not carry over to the second harvest when it could be better utilized. Later application dates would extend yield increases from certain species if water is available.
