The objective of this trial was to evaluate morphogenic response of Lolium multiflorum Lam. and Paspalum urvillei Steud., under levels of nitrogen fertilization (100, 200 and 300 kg/ha of N). Steers grazing this pasture received different energy levels supplementation (0.0, 0.4 and 0.8% of live weight [LW]), respectively, for the fertilization levels. A completely randomized design was used, where 90 tillers were evaluated by treatment (45 of each specie by replicate). Marked tillers were used to evaluate elongation, appearance and […]
