Data mining brings new clarity to plant breeding, according to new Iowa State University study

February 11, 2019

By Fred Love, University News Service

AMES, Iowa – The immense number of possible hybrids that can be created from inbred corn plants can leave plant breeders wondering where to start when attempting to produce new crop varieties with desirable traits. But new research from an Iowa State University agronomist shows how advanced data mining techniques can enhance the efficiency of the process.

Variable rate seeding prescription evaluate in corn

The purpose of this study is to evaluate different methodologies for developing variable rate seeding prescriptions in corn. Three prescription methods will be evaluated on yield and economics compared to a farmer chosen uniform rate. The three variable rate methods are normalized yield, topographic wetness index, and Corn Suitability Rating. This will be conducted in central Iowa in 2018 and 2019.

Evaluation of nitrogen fertilizer additives for enhanced efficiency in corn on Iowa soils

November 27, 2017

Recent years of high rainfall and prolonged wet soil conditions in Iowa have renewed interest to protect losses of fertilizer nitrogen (N) in corn. This study evaluated effect of N additives and a slow-release urea product on the soil NO3–N fraction of total inorganic N, mid–vegetative growth N stress, grain yield, and corn nitrogen use efficiency.

Accelerating Corn Elite Selections (ACES) Organic Breeding Program: Novel Strategies To Develop Field and Sweet Corn For Organic Producers

October 25, 2017

AMES, Iowa – Organic agriculture practices eschew many synthetic fertilizers and pesticides, putting pressure on crops that conventional farming circumvents. That means an organic farmer who doesn’t use herbicides, for instance, would value crop varieties better suited to withstand weeds.
