It’s time come plant tiny grains. As soon as planting oats, feather wheat, and also barley, farmers commonly plant 2 to three bushels of small grains every acre, however there is a better way come optimize tree populations and also grain yields. Farmers calculation corn and also soybean rates by seeds count and should execute the exact same for small grains.


Plant stands When planting oats, barley, or wheat, job-related to attain harvest plant populations of 1.0 to 1.3 million plants every acre or about 22 come 29 plants per square foot. Numerous factors influence final plant stands at oat harvest, including: desired final plant stand, variety of oat seeds per pound, germination rate in the seed lot, and expected stand loss from irregular seeding depth or early plant death.

You are watching: How many bushels of oats per acre

Calculating seeding rates Calculating seeding prices in terms of seeds per acre fairly than bushels will improve your planting accuracy and assist to optimize yields. Oat bushels are standardized in ~ 32 pounds per bushel, though there is a variety of actual check weights. In addition, particle number varies every pound depending on oat cultivar and also the growing problems under i beg your pardon the seed to be produced. Seed counts for oats can selection from 12,000 come 17,000 seed per pound and are no commonly listed on seeds bags. Seed certified dealer can carry out that info if they have an automatic seed counter in house. If seed counts space not readily available, weigh an oz of particle on a digital kitchen scale, count the seed per ounce, and also multiply that by 16 come calculate seeds per pound.

Calculating seed drop rate When calculating the seed fall rate, account for the much less than 100 percent germination price of your seed lot and also for stand facility losses, generally 10 come 20 percent. This will rise the lot of seed you must drop at planting. Use the adhering to formula to calculation oat seed autumn rate:

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

Calculate seed per pound and also multiply by the germination rate of the particle lot.

Divide #1 by #2 because that the final seeding rate.

The room of agriculture in Alberta, Canada has developed an digital calculator (link: to determine seeding rates for oats and also other small grains. Keep in mind that the rates are calculated utilizing grams no ounces. This can be convert by utilizing 28.35 grams every ounce.

If oat or other little grain planting is delayed, less tillering, under seed heads every acre, and reduced serial yield will certainly result. The college of Minnesota advises enhancing seeding rates by one percent for each day after the optimum spring little grain seeding date to compensate for less tillering.
