It’s time to plant small grains. Once planting oats, spring wheat, and barley, farmers generally plant two to 3 bushels of tiny grains per acre, yet there is a better way to optimize plant populations and grain yields. Farmers calculation corn and also soybean rates by seeds count and should perform the very same for little grains.


Plant stands When planting oats, barley, or wheat, work-related to accomplish harvest plant populations of 1.0 come 1.3 million plants per acre or around 22 come 29 plants every square foot. Several factors affect final tree stands at oat harvest, including: desired final tree stand, number of oat seed per pound, germination rate in the particle lot, and also expected was standing loss from irregular seeding depth or beforehand plant death.

Calculating seeding rates Calculating seeding rates in regards to seeds every acre rather than bushels will improve your planting accuracy and help to optimize yields. Oat bushels space standardized at 32 pounds every bushel, though there is a selection of actual test weights. In addition, seed number varies every pound relying on oat cultivar and the growing conditions under which the seed was produced. Particle counts for oats can range from 12,000 to 17,000 seed per pound and are no commonly detailed on seed bags. Seed certified dealer can administer that details if they have an automatic seed respond to in house. If particle counts space not easily available, weigh an ounce of seeds on a digital kitchen scale, count the seed per ounce, and multiply the by 16 come calculate seed per pound.

Calculating seed drop rate When calculating the seed autumn rate, account for the much less than 100 percent germination rate of her seed lot and for stand establishment losses, typically 10 to 20 percent. This will increase the quantity of particle you have to drop in ~ planting. Usage the adhering to formula to calculate oat seed fall rate:

Determine desired final stand per acre and divide by: (1-expected was standing loss).

Calculate seed per pound and multiply through the germination rate of the seeds lot.

Divide #1 by #2 for the final seeding rate.

The room of farming in Alberta, Canada has emerged an digital calculator (link: to identify seeding prices for oats and other little grains. Keep in mind that the rates are calculated utilizing grams no ounces. This can be converted by making use of 28.35 grams per ounce.

If oat or other tiny grain planting is delayed, much less tillering, fewer seed heads every acre, and also reduced serial yield will certainly result. The university of Minnesota advises boosting seeding rates by one percent because that each day after the optimum spring tiny grain seeding date to compensate for much less tillering.
