Given that uniform stands of corn are important for maximizing the yield potential of any given field (No-Till Corn Stand Establishment. I., P&C Newsletter, 4/5/96, No. 3) and that surface trash plays an important role in prevent uniform stands (No- Till Corn Stand Establishment. II., P&C Newsletter, 4/5/96, No. 3), what's a guy to do to ensure uniform stands of no-till corn? Here's a few tips and ideas to consider.

Planting Date Management. Okay, be honest with me. How many of you guys that no-till corn plant as early or earlier than when you planted into conventional tillage? After all, no-till ground supports equipment pretty dang well, doesn't it? Considering that the most common complaint I hear from disheartened no-till corn farmers revolves around "cold, wet soils", maybe.....just maybe....we should be planting no-till corn a little later than conventional till corn? Allowing the soil to warm up a tad and dry out a bit may be advantageous enough to outweigh the negative effects that we usually consider with delayed planting. Remember, soil temperatures at the seed depth should be consistently greater than 50 degrees F to encourage rapid corn germination and emergence within seven days after planting.

Hybrid Selection. The key factors for choosing hybrids for no-till environments are 1) overall yield performance, 2) hybrid traits important for no-till, and 3) seed quality.

Bottom Line on Hybrid Selection. Identify superior yielding hybrids. Eliminate those with obvious weaknesses for no-till. Accept only high-quality seed.
