Productivity, utilization and sward structure.h[electronic resource]  c2006  aThis study was carried out to evaluate the productivity, utilization and sward structure of a mixed massaigrass (Panicum maximum x P. infestum, cv. Massai) and forage peanut (Arachis pintoi Ac 01) pasture, intermittently stocked at three daily herbage allowance levels (9.0, 14.5 and 18.4% of live weight). In each grazing cycle, dry matter (DM) accumulation rates, defoliation intensity (%), grazing depth (%) and grazed horizon (cm) were evaluated. The structure of massaigrass tussocks was characterized in both dry and rainy seasons by measuring its pre-grazing morphological composition and postgrazing height and density (tussocks/m). Pastures submitted to higher herbage allowance (HA) levels showed higher productivity, but were less efficiently utilized. On average, over the experimental period, DM accumulation rates increased linearly from 56.8 to 81.3 kg/ha/day as HA levels increased from 9.0 to 18.4% of live weight. However, defoliation intensity and grazing depth declined linearly with increasing HA levels. During the dry season, pre-grazing morphological composition of massaigrass was characterized by 41% of green leaf blades, 10% of pseudostems and 49% of dead material, irrespective of HA levels. In the rainy season, however, it showed higher percentage of green leaf blades and lower percentage of pseudostems when submitted to lower HA levels, although there were not differences in relation to percentage of dead material. The structure of massaigrass tussocks tended to deteriorate at high HA levels.  aAgronomic traits  aArachis pintoi  aDefoliation  aDry matter accumulation  aForage legumes  aHybrids  aMixed grazing  aPlant morphology  aCaracterísticas Agronômicas  aDesfolha  aHíbrido  aLeguminosa forrageira  aMatéria seca  aMorfologia vegetal  aPastagem consorciada  aPastejo  aAcumulación de materia seca  aAmendoim forrageiro  aCapim massai  aDefoliación  aForage peanut  aGrazing depht  aHíbridos  aLeguminosas forrajeras  aMixed massaigrass  aMorfología de las plantas  aPanicum maximum x P infestum cv Massai  aPastoreo mixto  aProfundidad de pastoreo  aProfundidade do pastejo1 aGARCIA, R.1 aVALENTIM, J.
