Dinámica del crecimiento de una pastura de agropiro alargado de acuerdo con la época de fertilización nitrogenada

Abstract

Tall wheatgrass Thinopyrum ponticum (Bark and Dewey) pastures in the Pampa Buenos Aires, in general,are considered crops that concentrate growth during late spring to midsummer, with poor forage productionand of low nutritional value for animal production. In the EEA INTA Balcarce two trials were conducted on a pasture of tall wheatgrass in order to evaluate the effect of nitrogen fertilization on the dynamics of growth and accumulation of forage d ring two seasons: autumn-winter and spring, using 6 doses of nitrogen (DN) N0to N250, with increments of 50 kgNha-1 and using urea as nitrogen source.
