Resources use efficiency in tall fescue and annual ryegrass pastures with different nitrogen nutrition (Humid Pampa,Argentina)

摘要：

The Humid Pampa pastures frequently grow under suboptimal N nutrition.The series of experiments presented here were designed to better understand the agronomical impact and the efficiency of N fertilization practices that are expected to have an increasing demand because of the eminent agriculture area expansion in the region.Results on radiation and N use efficiency for two conspicuous temperate forage grasses‐Festuca arundinacea Schreb.( FA ) or Lolium multi f lorum Lam.(LM) ‐under different N fertilization levels applied in late autumn (AUT) or in early spring (SPR) are reported.
