Objectifs
Objective 1 : Develop management practices incorporating the latest technology developments for a field size aspirational four year, dryland crop rotation system with precision nutrient, agrichemical, weed control and crop population management. Sub-objective 1a. Identify and quantify production parameters most important in affecting economic yields across a dryland field-scape. Sub-objective 1b. Develop methods for quantifying optimal precision N management for specific management zones in wheat-based dryland rotation. Sub-objective 1c. Develop methods to quantify optimal corn populations for specific management zones in a four-year aspirational rotation. Sub-objective 1d. Develop and evaluate new tools for assessing soil quality across a field-scape using spectral scanning (FTIR) and other quick methods. Sub-objective 1e. Evaluate the use of drone based data for the quantification of crop water stress in dryland crop rotations. Objective 2 : Compare yields, economic returns, and environmental impacts of the aspirational rotation system, to a dryland rotation system currently used by producers of the region. Sub-objective 2a. Quantify and compare grain yields and economic returns from a precision-managed four-year aspirational no-till rotation with a “business as usual” reduced-till wheat-fallow rotation. Sub-objective 2b. Quantify and evaluate changes in soil quality as affected by both management systems across the field-scape. Objective 3 : Evaluate potential alternative crops and management practices for introduction into the aspirational wheat based dryland rotation system. Sub-objective 3a. Continue evaluations of germplasm and potential alternative crops for inclusion into wheat-based dryland systems. Sub-objective 3b. Evaluate new agronomic practices for inclusion into aspirational wheat-based dryland rotations.
