It looks like peaches and cream sweet corn but I could be wrong. Anyway very nice looking veggies!!
I planted G90 bicolor sweet corn. It claims to be a 90 day crop but it is always 85 days for me.
Google search says, corn needs 1 lb of Urea = 46-0-0 fertilizer every 50 ft.
Fertilize 3 times, when seeds are planted, when plants are knee high, when ears have silks.
A 50 lb bag of Urea is $20 at Farmers co-op. I have 128 ft of corn, seed spacing 5", that = 307 seeds. This was a bad year about 100 seeds did not grow. I picked 48 more ears today = 186 ears of good corn. I cut all the corn stalks down. About 6 pm I will use riding lawn mower to mulch and blow chopped corn stalks and cobs into the garden then till it into the soil.
