dc.description Winter wheat acreage increased 400% in North Dakota form 1981-84 and eventually stabilized at over 500,000 acres sown annually since the fall of 1983. Growing winter wheat in a spring wheat region include early spring growth, greater competition with weeds, a tendency to escape disease, temperature and moisture stresses that sometime occur during flowering of spring wheat. Using conventional management methods in the Northern Great Plains greatly increases the chances for winterkill of winter wheat. Production decisions involving tillage and tillage and variety selection must include consideration of potential winter injury and stand loss. The selection of winterhardy varieties and the seeding of these into standing stubble is recommended in those regions of North Dakota where continuous cropping is practiced. The covered in this article had the objective of studying the survival of winter wheat in low temperatures under conventional, reduced and no-tillage systems, to determine the influence of tillage and variety selection on winter survival and to study the relationship between grain yield and survival percentage as affected by tillage and variety selection. The methods, results and discussion thereof ensue. In summation, tillage and variety selection have a significant impact on winter survival of winter wheat and ultimately on grain yield. Choosing the proper tillage method can have more effect on winter survival than variety survival
