Wheat replanting decisions
If possible, replanting should be done at a 45 degree angle to the original stand to minimize damage to the existing stand.
Until the end of October, producers could cross-drill at the rate of 30-40 pounds per acre in western Kansas and 40-60 pounds per acre in central and eastern Kansas, using a double-disc opener drill if at all possible to minimize damage to the existing stand. If the replanting is done in November or later, increase the seeding rates to 60-75 pounds per acre in western Kansas and 75-90 pounds per acre in central Kansas. If stands are less than 30 percent of normal, increase the seeding rates just mentioned by 20-30 pounds per acre. If a hoe drill is used, the seeding rate should be higher than if a disc drill is used because the hoe drill will destroy much of the original stand. With a hoe drill, add about 20-30 pounds per acre to the seeding rates mentioned above.
Where there was no emergence in all or parts of the field, producers would have to use a slightly higher seeding rate than used initially -- 75 to 90 pounds per acre in western Kansas and 100 to 120 pounds in eastern and central Kansas, using the higher end of those ranges when planting in November or later.
Seeding rates on non-irrigated fields should not be higher than 90 lbs/acre in western Kansas or 120 lbs/acre in central and eastern Kansas. Under irrigation, seeding rates should never be higher than 150 lbs/acre.
