    Several grasses have been evaluated, over the years, for formation of pastures, seeking, above all, high productivity and persistence. Among these, grasses of genus Brachiaria and Panicum are evaluated in other regions such as southeast for example, and in semi-arid region,the type of grass that most arouses curiosity for research is Buffel. For semi-arid regions, another highlight is cactus pear, which feeds and maintains livestock during long periods of drought. Thus, the objective of the present work was to evaluate structural and productive components in intercropping of cactus pear and grass cultivars under irrigated management. The experimental design used was in randomized blocks (DBC), three cultivars of palm in association with one species of grass, in six treatments, palm Nopalea cochenillifera Salm Dyck (miúda-MIU) intercropped with the species of grass and single, palm Opuntia stricta Haw (Orelha de Elefante Mexicana - OEM) intercropped with the species of grass and single, palm Opuntia cochenillifera (Gigante) intercropped with the species of grass and single, six treatments and four replications, totaling 24 experimental units. The rackets were planted densely (1x0.25m) and with buffel between lines. Based on results referring to the study of grass growth and cladode growth in cactus pears, the respective variables were estimated. Biomass production was calculated and, for the evaluation of the morphogenetic characteristics of the cactus pear genotypes, two plants were selected per plot of central line and, as cladodes appeared, they were quantified and marked, weekly, with threads of different colors , according to the order of appearance in cladode hierarchy. Thus, the cladode appearance rate (TApC, cladode/day) and phyllochron (day/cladode) of cladodes were calculated. Weekly, using a ruler and caliper, length, width and thickness of the cladodes were measured, which allowed estimating rates of cladode elongation (TAlC in cm/day), of cladode enlargement (TAC in cm/day), cladode thickening (TEC in cm/day), area expansion (TEA in cm2 /day) and volume expansion (TEV cm3 /day). The biomass production was calculated and bromatological composition was performed. It was verified with this work that consortium of palm OEM, GIG and Miúda with buffel grass can be an alternative for semi-arid region of Alagoas by increasing efficiency in land use.
