Hi when I grow sweetcorn the corn seems to not mature properly very skinny narrow small cobs that stay white without many kernels which are very pale.i an in Brisbane Qld
Your corn is not being pollinated. Plant several rows - helps pollination. When the tassel (top part) and ears (cob) have come out, run your hand up (close the fingers in) the tassel to release the pollen and it falls down on the ears. It will collect the pollen as you run your hand up and then drop it on the ears, Plenty of water.
I usually give my corn a hit up with fertiliser when I hill the plants up when they are about 15-18" high. You could use de-composted manure or compost. The wind usually helps with the pollination process but sometime no wind or it is too strong.
