Description
Establishing alfalfa (Medicago saliva L.) without prior tillage offers advantages over traditional methods in terms of reducing energy and labour requirements, erosion hazard and improving timeliness of operation. An economic advantage to the no-till method has been apparent in recent years. Alfalfa was seeded without prior tillage.after annual crops and into perennial sods. Alfalfa was no-till seeded into perennial sod with less than 10% of the energy and labour required by the conventional tillage method. Alfalfa no-till seeded less than 1 week after sod was treated with glyphosate, was less vigorous and yielded less the seeding year than alfalfa seeded with a longer time interval after glyphosate treatment. Pesticides other than glyphosate increased seedling stands and seedling vigour of alfalfa the year of establishment; however, stands and yields were not significantly increased the year after establishment. Yields of alfalfa were greater when seeded into an interim annual crop, compared with no-till seeding into perennial sod.
