Forage yield gap analysis for tall fescue pastures in Argentina: A modelling approach por Insua, Juan Ramón, Machado, Claudio, Garcia, Sergio, Berone, German Dario

“…Darbysh.] under different growing conditions, using data from controlled field experiments; (a) use the evaluated model to predict the magnitude and time of the year that N or soil water would constrain tall fescue from attaining its potential growth rate in the south‐eastern Pampas of Argentina; and (c) quantify herbage production gains and temporal variability for a proposed improved management practice (IMP) of N fertilizer under different meteorological and soils scenarios. …”
