Experiences with Remote Sensing for Preplant and Split Applications of N for Corn Gyles Randall and Jeff Vetsch University of Minnesota Southern Research and Outreach Center http://sroc.coafes.umn.edu/ 1/17/2019

Purpose To evaluate the GreenSeeker and SPAD meter as diagnostic tools for making in-season N applications to corn. 1/17/2019

N applied: 4/30 (PP), 6/28 (V8), 7/13 (V12) Sensing dates: 6/23 (V7), 6/28 (V8), 7/7 (V10), 7/12 (V12), and 7/26 (R1). 1/17/2019

Corn Grain Parameter Yield N Uptake ------ r value 1/ ------ INSEY (53), V7 0.56 0.41 INSEY (58), V8 0.72 INSEY (67), V10 0.62 0.64 INSEY (72), V12 0.74 SPAD, V8 0.85 0.75 SPAD, V10 0.83 0.77 SPAD, V12 0.95 0.89 SPAD, R1 0.96 0.93 1/ Statistically significant when r > 0.404 (0.05) and r > 0.515 (0.01), df=22. 1/17/2019

Conclusions Although statistical differences were not found among the PP, V8, and V12 N application times, grain yield was 10 to 12 bu/A greater when the 80-lb N rate was applied PP compared to split between 40 lb/A PP and 40 lb/A either at V8 or V12 in this wet year. Relative leaf chlorophyll at the R1 growth stage was considerably less for the PP+V12 split application compared to the single PP or split (PP+V8) applications. Grain yield was correlated better with relative chlorophyll at all growth stages (V8, V10, V12) than with INSEY. 1/17/2019

Conclusions cont. INSEY was minimally affected by PP N rates between 40 and 200 lb/A, suggesting that this diagnostic criteria may have limited value if some N has been applied preplant for corn after corn. If no N was preplant applied and the initial application was made at V8, corn yields would likely be reduced significantly. 1/17/2019
