Description
The effect of winter nitrogen fertilization upon herbage accumulation during the winter-spring period on a natural pasture of the Flooding Pampa dominated by cool season annual (Lolium multiflorum) and perennial (Stipa neesiana) grasses was evaluated. The experiment was carried out from August to November in 1994 and 1995. Fertilization treatments were: 0, 50, 100, 150, 200 and 250 kgN ha- 1 (N0, N50, N100, N150, N200 and N250, respectively). The experimental plots were set out in three randomized blocks. In 1994, maximum forage accumulation was reached at N150, and no significant differences were found among N150, N200 and N250. In 1995, N250 showed the highest yield. No differences were found between N200 and N150, both being significantly higher than the rest of the treatments. In both years N0 showed the lowest forage yield. Though a 50% rainfall deficit during 1995 delayed forage growth initiation as compared to 1994, no significant differences in the total herbage accumulated in both years were registered.
