 Rates – current industry recommendations  Soil and Foliar Applied ◦ Boron, Chlorine, Copper, Zinc ◦ Calcium – Foliar only  NDVI, Soil, Tissue, Yield  4 site-years of data  Preliminary results ◦ no response to micros

 Preplant and early season irrigation  Seeding Rates – 40, 60 and 100 lbs seed/ac  N rates – 0, 60, 120 lb N/ac  Stand counts, head counts, NDVI, midseason biomass, final total biomass, grain yield

 Hollow Stem – 0, 40, 80, and 120 lbs N/ac  Flag Leaf – 40 lbs N/ac  Pre and post application NDVI, grain yield

 Surface, 3”, and 6” deep Sidedress N at V4  Rates of 40, 80, and 120 lb N/ac

Wheat y = 0.99x R 2 = 0.44 P = 0.34 Barley y = 1.15x R 2 = 0.80 P = 0.10
