El presente trabajo presenta los esfuerzos hechos para la estructuracion de una Red de Informacion Forestal Nacional desarrollados en el ano de 1995 de acuerdo con las directrices senaladas durante la Segund Reunion de la Red de Informacion de America Latina y el Caribe, en Resistencia, Argentina. Una reunion sobre la estructuracion de la red nacional y un curso sobre AGRIS y la Agrobase contaron con la participacion de 8 instituciones, todas editoras de documentos forestales. Otras instituciones confirmaron la intencion de trabajar de modo cooperativo en el area de informacion forestal. Se presenta tambien un comentario sobre los servicios de informacion forestal ofrecidos a traves de Internet por otras instituciones brasilenas. |

Variation in rainfall affects crops; therefore, agricultural practices become essential for forage production in semi-arid regions. This study aimed to evaluate the influence of different agricultural practices on phyllochron, structural characteristics of forage cactus and millet, and their relations with crop yield using the principal component analysis (PCA). The design was in randomized blocks, with six treatments: sole cropped cactus without straw mulching, sole cropped cactus with straw mulching, sole cropped millet without straw mulching, sole cropped millet with straw mulching, and cactus intercropping with millet, with and without straw mulching, each with four replicates. There were three cactus cycles and nine millet cycles (three cycles of cultivars BRS1501 and six of IPA Bulk-1-BF). Biometric parameters were evaluated monthly, while yield was determined after the crop harvest. Phyllochron was determined with the regression analysis. The PCA was applied to structural characteristics and yield. The systems adopted did not influence the structural characteristics of cactus and millet (p > 0.05), except for cladode thickness, which increased with straw mulching. Phyllochron of the millet reduced when the crop was intercropped. The structural characteristics of cladode length, width, and thickness influenced crop yield, mainly in systems with straw mulching. Straw mulching and intercropping alter phyllochron of cactus and millet. The adoption of straw mulching has a more significant relationship with cactus yield, whereas biometric variables influence crop yield for millet, not the cropping system.
