Effect of nitrogen fertilization on the growth of five perennial pastures in Ecuador.

Abstract:

Objective: To evaluate the effect of nitrogen fertilization on the growth and crude protein content of five perennial pastures of Ecuador. Materials and Methods: To evaluate the effect of nitrogen fertilization on the growth and crude protein content of the species Lolium perenne L. var. Alto, Lolium perenne x Lolium multiflorum var. Shogun, Festuca arundinacea Schreb var. Alta Barolex, Dactylis glomerata L. var. Quick Draw and Festuca arundinacea x Lolium multiflorum var. Premium, six progressive doses of nitrogen were applied (0, 70, 140, 210, 280 and 350 kg N [ha. sup.-1][year. sup.-1]). A split-plot design was used, where the species was placed in the large plot, and the nitrogen doses, in the small ones, with three repetitions. The variables biomass production, crude protein and normalized differential vegetation index, were evaluated. The data were analyzed through the statistical program INFOSTAT [R]. Results …
