Crops: Corn for grain (Ranked by 2004 cash receipts) 1  With Iowa leading the way, Iowa, Illinos, and Nebraska, together, produce almost 1/2 of the nation's grain corn. 2  The numbers listed for Value ($1,000) represent the value of the product or commodity in thousands of dollars.
Commercial corn today is 100% hybrid corn. This means that the seed corn is produced by cross-pollinating two inbred lines. Because corn plants have both male (tassels) and female (silks) reproductive parts, a seed corn field has to be altered in order to keep the plants from pollinating themselves and therefore just producing more inbred seeds. This is done by detasseling the 'female' rows of corn.
