Project Summary

Though assumed to be 50% when making nitrogen recommendations, the actual Nitrogen Use Efficiency/percent N recovery found in Kansas varies widely from a low of <40% to over 60%. Quantitative knowledge of the expected NUE from alternative N management strategies, or changes in NUE that could be expected by adopting different strategies under different production environments, would allow adjustment in N application rate and have a positive impact on sorghum yield and profitability. This project proposes to systematically obtain that information across a range of environments, and develop a framework to incorporate that NUE information into the Kansas N recommendation system.
