Documenting Nutrient Accumulation Rates in Four Barley Varieties


The proposed study will be conducted at the Aberdeen Research and Extension Center in Aberdeen, ID during the 2015 and 2016 growing seasons. Little work has investigated nitrogen or other nutrient accumulation in barley, particularly in the various classes (i. e. , malt, feed, and food). The proposed study would seek to fill this gap and provide detailed information for growers and researchers. Four barley varieties will be used consisting of two malt, one food, and one feed class.

Interpretive Summary

This project was designed to determine the "Right Time" aspect of nutrient accumulation of four distinct barley varieties (for animal feed, malting, human food, and adjunct). A study conducted in Idaho investigated the cultivar effects on barley grain yield, quality, nutrient concentrations, removal, and nutrient accumulation patterns under irrigated conditions for two-row barley cultivars.

Barley is a cereal grain grown for animal feed, human food, and malting purposes where varieties have been developed to meet the specific goals associated with each use. In addition, malting variety breeding goals now exist for all-malt and adjunct brewing purposes due to increases in demand from the craft brewing industry in the United States.

Data on nutrient uptake and partitioning in modern barley cultivars is limited. Research was initiated to investigate uptake and partitioning patterns in three classes of commercially produced barley (i. e. , feed, food, and malt). Through selective breeding, barley has been bred for high yields and relatively high protein levels (animal feed), food barley (i. e.
