What is corn RM?
Relative maturity (RM) is determined by comparing grain moisture of hybrids at harvest. Corn is mature when kernels reach maximum dry weight. Optimum RM depends upon the harvest, use and storage methods on each farm.

What does RM mean in corn seed?
The term “Relative Maturity” is often used when discussing corn and soybean seed. It is best defined as a criteria or process to compare or group hybrids and varieties based on physiological maturity.
What month do you plant corn in Kentucky?
Kentucky’s growing season is long enough that corn may be planted from early April to mid-May in most years and still obtain high yields. Optimal planting dates usually range from April 1 to May 1 in West- ern Kentucky and April 15 to May 15 in Central and Eastern Kentucky.
How do you pick a hybrid corn?
Look for hybrids that have consistently high yield performance from location to location and from year to year. To ensure this, look at multiple data sources, including public hybrid trials such as those conducted by the Iowa Crop Improvement Association as well as seed company and retailer trials.
How many years of testing does a corn hybrid go through?
Corn Adjusts to Later Planting A three-year study that was conducted by researchers at Purdue and Ohio State Universities documented that hybrids can adjust their growth and development, requiring fewer growing degree units (GDUs) to reach maturity when planted late (Table 1).
How long does corn take to grow from seed to harvest?
Corn requires from 60 to 100 days to reach harvest depending on the variety and warm weather. Corn is ready for harvest when ears turn dark green, silks turn brown, and kernels are soft and plump; squeeze a kernel and the juice will be milky, not clear.
What can I plant in April in Kentucky?
If you’re interested in extending the growing season, you can plant cool-season crops like broccoli, peas, cauliflower, green onions, and lettuce/greens in the spring and again in the fall. For detailed information on vegetable gardening in Kentucky, click here. Happy planting!

What is ad hybrid corn?
Definition of hybrid corn 1 : a corn resulting from crossbreeding specifically : the grain of Indian corn developed by hybridizing two or more inbred strains.
How do I choose a corn variety?
Different varieties have different characteristics; for example, white corn is high in carbohydrates, yellow is high in vitamin A, and colored (“Indian corn”) is high in minerals. In general, higher test weight seed is of higher quality. To go through a planter well, seed should be graded for uniform size.
Why is hybrid corn important?
Hybrid corn varieties– both single- and double-crosses – have significant benefits. Plant breeders intentionally create varieties with particular traits; they might be fast-growing, or able to tolerate drought, or particularly resistant to a pest like European corn borer.
What is importance of corn hybrid breeding?
Hybrid maize generates high yields, increased value and reduced production costs. The plants are bigger, stronger and more vigorous. This hybrid vigor, or heterosis, occurs when crossing two genetically unrelated inbred parents to create a hybrid.
