Using informative Bayesian priors and on-farm experimentation to predict optimal site-specific nitrogen rates
(2023-05)
Precise site-specific nitrogen applications will reduce excess nitrogen fertilizer run-off and have corresponding environmental benefits. Adoption of site-specific nitrogen application technology has been slow, and many ...
By-plant Sidedress Nitrogen in Corn (Zea Mays L.) Based on Plant Height and Normalized Difference Vegetation Index
(Oklahoma State University, 2012-07-01)
Current methods of applying nitrogen (N) fertilizer do not treat small scale variability that is known to exist. Variations in corn grain yield can be found from one plant to the next. With knowledge that yield potential ...
Effect of the method and rate of planter applied nitrogen on corn and grain sorghum production
(2023-05)
In Oklahoma corn (Zea mays) and grain sorghum (Sorghum bicolor L) account for nearly 20% of all the total value of farmed cropland in the state. Fertilizer, specifically nitrogen (N) is one of the greatest input cost and ...
