Sow directly when ground temperature reaches 18 degrees Celsius. Cold ground temperatures will result in poor germination as the seed is untreated and may rot. Space rows 76-90cmapart, sowing every 15-17cmat a depth of 2.5cm. To achieve maximum pollination sow corn in blocks as opposed to a single row. Corn is wind-pollinated and having the plantsin close proximity toeach other will ensure well filled ears.
