Fresh Local Sweet Corn Arriving On Schedule
Growers across the state are reporting that this year's sweet corn crop is arriving about on schedule. Paul Lebo of Oak Grove Farms in Mechanicsburg, Cumberland County, plans to start picking sweet corn about June 20 each year - this year it was June 22. Funk's Farm Market in Millersville, Lancaster County, also began harvesting its corn, which they had planted under clear plastic, on June 22. Bob Trax of Trax Farms in Finleyville, Washington Co., expected to have corn for July 4, their usual starting date.
While the weather was a little cooler than usual earlier in the spring and wet weather in many areas made planting schedules a challenge, the crop in general looks good so far. Assuming continued good weather in the coming month or so, consumers can expect an abundant supply of "Simply Delicious, Simply Nutritious" Pennsylvania sweet corn at community farmers' markets, roadside farm markets and supermarkets across the state throughout the summer. Fresh, local sweet corn is not only the best tasting corn to be had, it is also often available at economical prices at the height of the season in August. Thus in these days of increasing food and fuel costs, it represents a real food dollar bargain with a small carbon footprint besides the great taste.
Paul Lebo starts planting his corn around March 13 and plants about 12 acres a week until early July for a total of 160 acres of the summertime treat. This gives them a continuous harvest from late June until the beginning of October. They supply their own retail farm market as well local supermarkets such as Giant Foods, Weis Markets, Wegmans, Karns and Shurfine with about 2,500 dozen ears a day. Their customers prefer the white and bicolor varieties over the yellow varieties.
The corn being harvested in June and early July has been seeded under a clear plastic mulch. The warm moist environment under the clear plastic mulch is ideal for rapid seed germination and seedling development in cool March and April days. Some growers go an extra step and start their corn in the greenhouse and transplant it to the field under clear plastic row covers supported by wire hoops. Either system represents a greater investment for the grower in terms of time, equipment and supplies but enables the grower to hit the early market. Corn planted on bare ground with no row cover generally matures two to three weeks later.
Irrigation is essential to a good corn crop in many years. The critical period for adequate moisture for corn is during silking and ear development. Traditionally corn has been irrigated by overhead sprinklers or large irrigation guns that cover a large area at once. Many sweet corn growers are now turning to trickle irrigation which is the most water-efficient method of irrigation available. With this method of irrigation, a plastic tube with tiny emitters is laid down between every other row of corn. Water and fertilizer are pumped into the tubes and trickles out to the roots of the sweet corn crop.
The key to great-tasting sweet corn is freshness. The sugar in sweet corn rapidly begins turning to starch within hours after being harvested. About 40 percent of the sugar can be lost in six hours at room temperature. Refrigeration slows this process, but the sooner corn is eaten after harvesting, the better it will be.
Most growers are growing sugar-enhanced or super-sweet varieties that genetically have more sugar in the kernels. Some of these early sugar-enhanced varieties where developed at Penn State University. Because they have more sugar to begin with, they can be stored for longer periods and still have acceptable sweetness. However, standard sweet corn varieties, when purchased freshly harvested, will still have a delicious, traditional corn flavor and sweetness.
According to growers across the state, most Pennsylvanians prefer bi-color corn, traditionally known as Butter and Sugar. However, in south central and southeastern Pennsylvania, white is the preferred corn. Certain localities and clienteles still like their corn to be yellow, so many growers also grow some yellow varieties.
Sweet corn is the leading vegetable crop in the commonwealth with about 17,200 acres grown annually. About 86 percent of this sweet corn acreage is grown for fresh market sales. As a result, Pennsylvania ranks as the seventh largest fresh-market sweet corn producing state in the nation. About 2,400 acres of the sweet corn acreage are grown to be pro-cessed into frozen, dried or canned corn products available year around. Fresh corn will be available from late June into October.
While fresh sweet corn is a delicious ingredient in many recipes, it is most popular served right on the cob, and is so simple to prepare with these tips from Penn State Cooperative Extension. Simply boil husked ears for four to seven minutes in unsalted water - salt may toughen the kernels. If you prefer grilled corn, remove the silk from the ear but leave the husk on. Soak the ears for 10 minutes in cold water and then grill them for 15-20 minutes. To roast, remove the silk and husk from the ears, brush with melted margarine or butter and wrap in foil. Roast the wrapped ears for 15 to 20 minutes on the grill.
Fresh corn-on-the-cob is also easily prepared in the microwave by wrapping two husked ears in a damp paper towel and cooking them for seven minutes on high power, turning the ears once.
Many roadside farm markets offer larger quantities of corn for home freezing. Penn State University offers detailed instructions on the Web at http://foodsafety.psu.edu/lets_pre serve.html, This information is also available at any Penn State Cooperative Extension office or by contacting the Pennsylvania Vegetable Marketing and Research Program at 717-694-3596. Many general cookbooks offer detailed instructions and recipes as well.
