Should be at least four rows wide to ensure good pollination. In loamy soils and one to two inches in sandy soils. Space early varietiesĨ to 10 inches apart in the row (20,000 plants/A) and the remaining varieties 10 toġ2 inches apart in rows (14,000 plants/A). Plant 10 to 12 lbs/A of graded seed in rows 36 to 38 inches apart.
For additional information on fertilizing, consult Extensionįact Sheet HLA-6036, available at your county Extension office or online at. Ppm may need zinc included in the preplant fertilizer to promote good sweet corn growth Soils with available zinc levels below 0.8 Additional N may be needed to produceĭark green husks for good market quality. Or topdress 60 lbs/A N when corn is one foot high. Nitrogen: Apply 50 lbs/A (pounds per acre) N with the P 2O 5 and K 2O fertilizer, as shown in the preceding table, at preplant or planting. To determine if they offer some advantage over currently grown varieties. Quality will be greater in cool, dry weather. The actual number of days required to reach harvest Reduced eating quality compared to those that mature later. Early varieties often produce smaller ears and have Sweet corn varieties that have performed well in Oklahoma trials are described inĮxtension Fact Sheet HLA-6035. If theĬorn is offered for sale, check the product regularly to ensure that cross-pollination Separate the plantings with at least four to six border rows. If isolation space is limited, plant the most affected variety on the upwind side the silk on one variety is dry before or after the tassel on another develops). Of sweet corn by at least 250 feet or by planting so the flowering occurs at different Which could affect kernel sweetness or color by separating stands of different types Wind pollinated, therefore farmers will need to reduce the risk of undesirable cross-pollination, Table 1 summarizes isolation requirements of the various types. Pollinated by varieties having the dominant forms of these genes, sweetness will be If varieties having these “sweet” genes are

Growers should make small trial plantings initially to determine They also have smaller, more brittle seeds, which crackĮasily if mishandled. Seed of supersweet types may not germinate as well as normal or modified sugary types, Tougher skinned, lower in starch and retain their quality longer after harvest. Compared to normal or modified sugary types, supersweet types are higher in sugar, Sugary sweet corn because of its shrunken2 gene (sh 2). Supersweet corn has higher sugar content than normal sweet corn or modified Modified sugary sweet corn has the sugar-enhancer gene (se) which increases the sugar content of the kernel by modifying the sugary1 gene. Merit) has the recessive version of the “ sugary1” gene (su 1). Sugary sweet corn, and supersweet corn comes from different genes. The sweetness in normal sweet corn, modified Thus, for example, if a white variety receives pollenįrom a yellow variety, ears on the white variety will have bicolor kernels.Īnother feature which has become increasingly important in selecting a sweet corn SweetĬorn kernels may be yellow, white, or a mixture of yellow and white (termed bicolor).
Sweet corn varieties are often classified by seed color and by maturity date. For early production,Ĭhoose sandy soils that can be plowed early on a site that is not subject to late Sweet corn grows on a wide range of well-drained sites and soils. Of sweet corn in Oklahoma is 1,000 dozen ears (200 bu) per acre. To corn earworm is especially important if fall production is attempted. Program throughout crop development is necessary. Fall production is possible, however an intense insect control Without an adequate insecticide spray program during the silking to harvest stages Temperatures, which normally occur in early July, interfere with pollination and preventĬorn earworm is a serious insect pest, and sweet corn production should not be attempted Growing conditions in central Oklahoma provideĪbout a six-week harvest period beginning in early June and ending in mid-July. It is subject to serious injury if exposed to prolonged cool temperatures Sweet corn is a warm season crop, easily killedīy frost. Large-scale production requires a considerable investment in harvesting equipmentĪnd packing and hydrocooling facilities to prepare shipments for terminal markets Sold directly from the farm or at roadside stands, farmer’s markets or local stores. High quality sweet corn is a very popular vegetable.
