Corn Plan and request for comments

15 years ago

Would appreciate comments and suggestions on this corn schedule for the spring. I have read that synergistic varieties such as serendipity and honey select don't need isolation. Do they need isolation from each other and can they be grown with other types?

My fields are really just small adjacent plots able to handle about 50 plants each (5 rows x 10 plants). The only isolation I can provide is time and I have attempted to plant the fast growers first to get a bit more time separation on tasseling.

Early Sunglow 62 days, 5-May, SU

xtra tender 277A 77 days, 19-May, SH2

Honey Select 79 days 2-Jun, SYN

Serendipity 82 days, 2-Jun, SYN

Sugar Dots 85 days, 16-Jun, SU

Silver Queen 91 days, 30-Jun, SU

Thanks

Scott

If you don't want varieties to cross, keep them separated by time. I wouldn't want Honey Select and Serendipity to cross just because they are related.

I would move Extra Tender up to about May 10..Honey Select to May 22..Serendipity up a couple days..Sugar Dots about June 10 and Silver Queen about June 20. That Silver Queen might not do well planted late as the daylight hours shrink near maturity.

Silver Queen will be a problem with your proposed planting date. It is a long season corn and will still be growing way too late in the fall.

I'm zone 7 as well with a growing season for corn from late March thru October. My plan is one early maturing variety planted very early, late March. This variety must have tolerance to cold soil in early spring. Then starting in early April the soil is warm enough to plant the same full season variety every 2-3 weeks. Actual planting date is based on size of the prior planting. When a prior planting reaches about 6-8 inches tall, I plant another planting. This gave 7 plantings last year and 9 the year before that.

I have corn to eat from mid June until early November.

By planting the same variety every 2-3 weeks there are no pollination issues and a constant supply of corn. My last planting of a ~76 day corn is about August 1. So far no freeze injury on either end of the season.

I'm changing varieties in 2011, all from Harris seed. Thinking Sweet Chorus, SB 67 day, as an early. It's supposed to be a very strong grower in cold soil and good quality. For all later plantings I may try 7002R, shA and 72 day, for it's quality and resistance to leaf rust. Leaf rust gets bad here on the last 3-4 plantings.

Will the two synergistic varieties cross pollinate? The catalogs seem to indicate otherwise.

Could be wrong. But the two SYN will cross pollinate but it won't have any effect on taste. If one is yellow and one white, they may both end up mixed but that won't affect eating quality.

Scott,
I think you've got too many varieties for that small a space. I agree with the others that Silver Queen may not produce well planted that late. And I worry that your SH2 might cross causing starchy kernels with your proposed June 2 sowings. I might suggest keeping Sunglow as your 1st early (Sunglow has never failed me!), then like Fruitnut says pick one of the SY or SH2 midseason varieties and sow it every 2-3 weeks.
