The high-density hybrids need additional fertilizer to reach their full yield potential. Stine also recommends applying fungicides to high-density corn.

Future high-density hybrids may be much shorter than current hybrids. Stine has started selecting for shorter plants. Why? He says tall hybrids waste energy-producing unneeded biomass. Instead, short hybrids have more upright leaves sticking above the tassel for efficient photosynthesis. This creates more corn yield.

And in the end it is all about yield. Stine will continue his quest to build yields to 300 bu. and beyond. He says Stine Seed will have hybrids able to handle 65,000 plants/acre in the future. If that happens, growers may need to invest in 10-in.-row equipment.
