Corn yield following a delayed application of nitrogen

Brian H. Yoder Illinois Digital Environment for Access to Learning and Scholarship (University of Illinois at Urbana-Champaign) 2018

Other claims from this paper (13)

Intervention effect In corn following soybean, delaying the second half of N to as late as R2 did not cause significant yield loss.
Intervention effect Corn with N applied at R3 yielded 92% of the yield of corn with the second application at V3.
Intervention effect Delaying all 224 kg N ha-1 through V15 reduced corn yield with application at VT, R2 and R3 (12, 19 and 37% less).
Intervention effect In corn following corn, delaying the second half of N to R3 gave 96% of the yield of the second application at V3.
Intervention effect In corn following corn, none of the delayed N timings significantly lowered yield.
Intervention effect Delaying all N to V9 did not significantly decrease corn yield.
Intervention effect Delaying all N to V12 reduced corn yield by 11% relative to earlier timings.
Intervention effect Delaying all N to R3 reduced corn yield by 42%.
Recommendation Without N at planting, N must be applied by mid-vegetative stages to prevent corn yield loss.
Intervention effect When half the N was applied at planting, delaying application until past pollination caused surprisingly little corn yield loss.
Observation Split-N corn treatments recovered healthy leaf color (SPAD) no matter how late N was applied.
Intervention effect With no N at planting, corn plants could not regain full leaf color or yield if N was applied later than mid-vegetative stages.
Recommendation If all N is delayed, application should be made before plants reach mid-vegetative growth stages.
