Effect Of Late Nitrogen Fertilization On Grain Yield And Grain Filling In Corn, J. A. Fernandez, I. A. Ciampitti
Effect Of Late Nitrogen Fertilization On Grain Yield And Grain Filling In Corn, J. A. Fernandez, I. A. Ciampitti
Kansas Agricultural Experiment Station Research Reports
For decades, yield improvement in corn has been accompanied by an increase in plant nitrogen (N) uptake. Modern hybrids are absorbing more N during reproductive stages, while delaying N remobilization to the grain for later in the growing season. To evaluate the effect of late-season N applications in distinct corn genotypes, grain yield and grain filling parameters were evaluated in field experiments under early and late N regimes during 2017 and 2018 growing seasons. Hybrids with different release years (3394, 1990s; P1151, 2000s; and P1197, 2016) and contrasting N application scenarios (including a zero-N control) were evaluated at the Kansas …

The aim of this study was to evaluate different management strategies for improving yield productivity in corn (Zea maysL.) and soybean [Glycine max(L.) Merr.] rotation systems. During the 2018 season, a long-term corn-soybean experiment was continued in Scandia, KS, evaluating five management strategies under rainfed and irrigated conditions. For corn, average yields were 146 bu/a and 172 bu/a under rainfed and irrigated conditions, respectively. For soybean, rainfed and irrigated average seed yields were similar (47–50 bu/a), attributed to herbicide injury on the irrigated plots. For both crop and water scenarios, intensifying the crop management (by modifying …
