Validation and use of critical phosphorus concentration in maize

2020-10-01

Abstract excerpt

Plant-based indicators may have the potential to improve fertilizer phosphorus (P) recommendations for maize (Zea mays L.). Our objectives were (i) to validate existing models of critical P concentration (Pc) in maize shoot biomass during vegetative growth and (ii) to evaluate on farm the ability of the P nutrition index (PNI), a plant-based indicator derived from Pc, to predict a positive response to P fertilizat...
