Trial effect of timing of Roundup CT and Spray.Seed application and cultivation on crop establishment and growth.
The general tendency was for yield to decrease as the time to seeding after Spray.Seed application increased.
For trial 87NO85 the site was a 'problem', heavy textured soil where crop emergence problems following glyphosate had been experienced in previous years.
Crop establishment - time of seeding following herbicide application.
Use of a knockdown herbicide greatly increased yield when compared to the unsprayed treatments. Further work is required to resolve contrasting results.
