Players gain 17 Farming experience for planting 3 sweetcorn seeds and gain 19 Farming experience for each ear harvested.
A scarecrow is used to protect growing sweetcorn from disease, and nine raw sweetcorn are used as payment for a farmer to watch over your growing apple tree. Putting 15 raw sweetcorn in a Compost Bin will yield normal compost.
A farmer will protect sweetcorn for 10 jute fibres.
It takes about 50 minutes to grow sweetcorn.
Players can cook sweetcorn on a range or a fire to make cooked sweetcorn (or occasionally burnt sweetcorn); this requires level 28 Cooking, and gives 104 experience. Cooking Sweetcorn gives a decent amount of experience, and thus is one of the ways that low-level members train their Cooking skill. Players stop burning sweetcorn at level 54 Cooking using a fire.
It is more frequently used as an ingredient in making tuna potatoes.
Players can also take raw sweetcorn to a windmill, put it in the hopper, and use an empty pot on the flour bin to get the pot of cornflour used to free Sir Amik Varze in the Recipe for Disaster quest.
