| dc.description | Low sustainability and short persistence of renovated pastures are main issues for pastoral
production systems. Pasture establishment and the first year of production were evaluated
following different pasture improvement methods. On a degraded pasture (control),
treatments of fertilized naturalized pasture (FNP), cultivated pasture (CP: Lolium perenne
[Lp]) and Trifolium repens [Tr]), direct-drilled pasture (DP: Lp and Tr) and diverse directdrilled
pasture (DDP: Lp, Bromus valdivianus [Bv], Holcus lanatus [Hl], Dactylis
glomerata [Dg] and Tr) were evaluated within a completely randomized block design. The
trial was grazed by sheep. Soil fertility levels, seedling establishment and development,
pasture growth, herbage mass and botanical composition were analyzed using ANOVA and
LSD. After one year, soil aluminum saturation was low, Olsen-P medium and exchangeable
potassium high. At 110 days after sowing, Lp had greater tillering than other grass species
and its development at plant level was similar in all sowing methods. Sown species total
leaf area was similar for all sowing methods and the improved pastures had a greater
maximum pasture growth rate than NFP, but differed in their growth distribution across
seasons. The accumulated herbage mass was similar for all improved pasture treatments. In
conclusion, direct-drilling and pasture cultivation appeared to give a good pasture
establishment. At seedling stage, Lp was faster growing than neighboring species.
Increasing species diversity diminished seasonality of pasture growth. All the pasture
improvement methods gave a higher total yield than the degraded pasture. | |
