Other claims from this paper (14)

Intervention effect Fruit circumference growth increased linearly with TAW level in phases 2 and 3.
Observation Most total fruit growth was completed during phase 2.
Observation Most shoot extension growth was completed during phase 1.
Intervention effect Shoot growth was more vigorous at 85% TAW than 25% TAW during phase 2.
Observation At 85% and 65% TAW, trunk growth was completed mainly at the end of phase 2.
Observation At 45% and 25% TAW, trunk growth was completed by the end of phase 1.
Association Trunk growth correlated positively with water application in phases 1 and 2 and slightly in phase 3.

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 did not decrease corn yield significantly.
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 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.

Cover crops did not change optimal corn nitrogen rate over three variable precipitation seasons in the Western Corn Belt

Tauana Ferreira de Almeida; Lucas Pecci Canisares; Emily Robinson; et al. Agronomy Journal 2025. doi:10.1002/agj2.70129

Other claims from this paper (7)

Intervention effect Cover crops did not decrease corn grain yield at the AONR.
Intervention effect Cover crops did not increase the AONR compared with the no-cover crop treatment.
Observation In 2021, with near-normal precipitation, corn yield at the AONR and the AONR were the highest of the three years.
Observation In 2022, with about half the 30-year average rainfall, yield at the AONR decreased across treatments.
Intervention effect In 2023, cover crop treatments had no significant effect on the AONR.
Mechanism Weather was the dominant factor driving the AONR.
Recommendation The results do not support the need for higher N rates after winter cover crops.
