Oh come on Norm!! There is no such record on record. What would the purpose of such a record be? Human consumption. The ears maybe, not the stocks. That would be fodder not something grown for human consumption. Come on we can do better than that!! Gianty.

golaith corn from RHShumway MIGHT BE A GIOOD PLACE TO START . Save the seeds at any rate.

With 20 tillers, it sounds more like teosinte than corn, or maybe a teosinte-corn hybrid. The plant produced ears?
I tried producing a teosinte corn hybrid this year, but the teosinte (Zea nicaraguensis and Zea mays subsp. huehuetenangensis) seem to have extremely long growing seasons. I'm going to have to stop them indoors in the winter to have a chance of a cross.

At the Royal Winter Fair my corn measured in at 25 feet 6 inches.And the stalk weighted 25 lbs. My 21 foot stalk weighted 21 lbs.
My Teosite corn Hydrid plant weighted 65 lbs.

Weight of biomass produced gets important if you're growing for biomass to be charred for bio-char, or for biomass to be shredded for mulch, or for biomass to be composted for fertilizer for next year's crop. Charring biomass (in this case cornstalks) can provide a variety of fuels and chemicals.

I would like to get seed to grow big corn if anyone has any available

Hey ncraven,what kind of corn did you plant that got 25 feet tall? And do you have any for sale?
