[QUOTE="ollie989898, post: 7061958, member: 54866"] The usual answer was stress. Any kind of grief and it will attempt to respond by throwing more cobs. The bulk of secondary cobs often do not fully ripen or reach the size of the first. Typically you would expect 1 fully formed cob to appear, often the second is a bit smaller. If they are both of equal size the plant has had a pretty good life I would say. Seen plenty of two cobbed plants in the USA. It's a genetic trait but there is thought to be some environmental effects involved. Higher populations of corn (the USA pushed these to get more yield) seemed to encourage it but they can sometimes be barren if there isn't enough pollen about or they form/silk at the wrong time. I don't recall ever walking a crop in the UK that had the bulk of the field only producing one cob. Some good crops pictured above. Excellent weed control even now with no weeds present under the canopy. [/QUOTE]
