Title
Corn Grain Yield and Nutrient Response to Foliar Fertilizer Applied during Grain Fill1
H. J. Harder; R. E. Carlson; R. H. Shaw Agronomy Journal 1982. doi:10.2134/agronj1982.00021962007400010027x
Other claims from this paper (9)
- Intervention effect Foliar fertilizer applied from 2 weeks after silking reduced corn grain yield by 6.4% in 1977.
- Intervention effect Foliar fertilizer applied from 4 weeks after silking had no significant effect on corn grain yield or yield components in 1976.
- Intervention effect Foliar fertilizer reduced mass per kernel in one corn hybrid in 1977.
- Intervention effect In the other corn hybrid, mean mass per kernel and kernels per plant were not significantly changed by foliar fertilizer in 1977.
- Intervention effect Foliar fertilizer reduced total grain yield in one corn hybrid.
- Association The difference in foliar fertilizer response between corn hybrids is related to the number of days after silking when the fertilizer was first applied.
- Mechanism Foliar fertilizer seemingly produced a stress on corn plants, and the stress was expressed through yield components determined when it occurred.
- Intervention effect Foliar fertilizer applications increased the nitrogen content (10%) of corn grain at harvest.
- Intervention effect Foliar fertilizer increased corn grain N yield (5.1%) despite a grain yield decrease in one hybrid.
