Seeding Rate

How many seeds does it really take to get 100,000 plants per acre at harvest?

Yield response across four planting dates

jvandyk — Thu, 05 Apr 2007 10:19:59 -0500

Yield response for four harvest plant populations averaged across four planting dates for two studies. Study 1 was conducted at Ames, Crawfordsville, and Nashua from 2003 to 2005. Study 2 was conducted at DeWitt, Nevada, and Whiting from 2004 to 2006. Yield values are not significantly different from each other when the difference between values is less than the LSD.

Seeding rate and harvest population

The relationship between seeding rate and harvest population. Ideally, we would like to have every seed planted be present at harvest; this would signify a 1:1 ratio. Most hybrids have a 95 percent germination rate, which means that each seeding rate should parallel the 1:1 line, except that it would be slightly below it. As the seeding rate increases though, the final populations start to drag down from the 1:1 line.
