Nitrogen, phosphorus, and potassium fertility requirements for optimizing protein levels in malting barley

For optimum economic returns, fertilizer applications should be managed to apply sufficient N to attain the highest possible yield, without increasing protein content beyond the acceptable levels. For optimum profitability, a fertilizer management system must consider the balance among the major nutrients rather than simply N and moisture in isolation.

IPNI-1990-CAN-MB4

This research project was designed with the following objectives: 1) To determine N, P and KCl fertilization which will optimize grain yield at various moisture levels, while maintaining protein content within required limits. 2) To determine the effects of N, P and KCl management on malting quality of barley. 3) To evaluate the effect of KCl fertilization on disease incidence in malting barley at varying levels of N, P and soil moisture.
