Maximizing winter wheat production with conservation tillage in the Northern Great Plains
Project assessing the potential for reduced tillage production of winter wheat in the Northern Great Plains
IPNI-1985-USA-MT4
13 Jun 2001
Objectives
- Maximize winter wheat production in semiarid regions of the Northern Great Plains. The winter wheat yield goal will be 10 bu/acre/inch of investigations outlined in objectives 2-5.
- Determine the timing and extent of water and nutrient extraction from the soil by winter wheat varieties as affected by summer fallow and conservation tillage cropping systems.
- Compare root exploration patterns of winter wheat varieties on summer fallow and conservation tillage acreage.
- Differentiate winter wheat varieties relative to nutrient and water use efficiencies and yield and protein response to tillage and nutrient variables.
- Determine the optimum seeding rate and row spacing needed for maximum winter wheat production on no-till and fallow conditions.
