Sweet corn cultivation profit harvesting stage green cob market difference from field maize.

Sweet corn can be profitable near cities because it sells as fresh green cobs at a premium, but it is a different crop from grain maize in management and timing. You harvest sweet corn at the milk stage, usually around 70 to 80 days, when kernels are tender and sugary, not at full grain maturity. Picking at the right milk stage is critical because sugar converts to starch quickly after harvest, so sell or cool the cobs fast. It needs assured irrigation, good market access, and isolation from field maize to keep sweetness. Returns depend heavily on fresh market demand and how quickly you can move the produce. Start with a small area to learn the market before scaling up.
Near Pune sweet corn sells well to vendors and roadside roasters. The key is picking at the milk stage and selling the same day, otherwise it loses sweetness. Margins are good if you have a buyer ready.
I grow it in small lots staggered every two weeks so I have a continuous harvest for the market. It needs more care and water than grain maize but the per cob price makes up for it.
Keep your sweet corn block away from field maize, otherwise cross pollination spoils the sweetness and you get starchy kernels. I plant it in a separate corner or sow it at a different time so they do not flower together.
The biggest risk is having no buyer ready, because the cobs do not wait. One time my trader backed out and the crop turned starchy in two days. Now I confirm the buyer before I even sow.
