Abstract: Harvesting machines are provided for use in harvesting corn from corn plants. An example harvesting machine includes a tractor and at least two row units coupled to the tractor and operable to remove ears of corn from corn plants. A first row unit of the at least two row units is moveable relative to the tractor to change a height and/or rotational position of the first row unit, and a second row unit of the at least two row units is moveable relative to the tractor independent of the first row unit to change a height and/or rotational position of the first row unit.

Abstract: The present invention provides a seed blend comprising pesticidal seed and refuge seed, wherein plants grown from said pesticidal seed type do not pollinate plants grown from said refuge seed type when the seed blend is planted. In some embodiments, the refuge crop reproductively matures at a different time relative to the time at which the pesticidal crop reproductively matures. Methods for deploying the seed blend and for reducing cross-pollination between plants grown from the pesticidal seed and refuge seed are also provided.
