| Estudaram-se características morfogênicas e estruturais de azevém (Lolium multiflorum Lam.) sob intensidades de pastejo. O delineamento experimental foi inteiramente casualizado, com quatro repetições (transectas) e três tratamentos constituídos por intensidades de pastejo: “Alta”, “Média”, “Baixa”, correspondentes ao desaparecimento de 61,0; 43,3 e 21,1% do valor da massa de forragem inicial, respectivamente. O pastejo foi intermitente, com borregas, e o intervalo entre pastejos correspondeu à soma térmica de 313 graus-dia. As intensidades de pastejo afetaram a morfogênese e estrutura de azevém apenas no primeiro período de avaliação, quando o azevém na intensidade “Média” apresentou as menores taxas de aparecimento e elongação foliar e os maiores valores... |

| This work was carried out in order to generate information on the tillering process and to contribute for the understanding of the defoliation process on Italian ryegrass (Lolium multiflorum Lam.) grazed by lambs under different herbage allowances: 6, 8 and12 kg of dry matter per100 kg of animal live weight per day. The grazing method was intermittent. The experimental design was completely randomized following a repeated measure arrangement, with three treatments and two area replications. The intensity of defoliation is greater at 6 and 9% herbage allowances. The defoliation interval is higher at 12% herbage allowance, intermediate at 9% and lower at 6%. The rates of tiller emergence, survival and death, stability index the tiller population are... |

| The objectives of this study were to evaluate morphogenetic characteristics and tillering dynamics in Tanzania grass fertilized and non-fertilized with nitrogen, under intermittent grazing, in the spring and the summer. The main plots were composed of four nitrogen rates (0, 100, 200 and 300 kg/ha) and the subplots were growth seasons: spring (October, November and December) and summer (January, February and March). The experimental design was of randomized block with plots subdivided by time (seasons of the year) and four replications. Urea was used as nitrogen supply and was divided into two applications: one in the spring and another in the summer. The experimental units fertilized with N rates of 200 and 300 kg/ha showed six cycles of pasture, with an... |
