Foram testados diferentes substratos, com o objetivo de verificar os que proporcionam melhores condições para o desenvolvimento do mandacaru (Cereus jamacaru P. DC.), o facheiro (Pilosocereus pachycladus Ritter), o xiquexique (Pilosocereus gounellei (A. Webwr ex Schum.) Bly. ex Rowl.) e a coroa-de-frade (Melocactus bahiensis Britton & Rose). O delineamento experimental utilizado foi em blocos ao acaso com cinco substratos (areia, solo, areia + solo, areia + esterco de bovino e solo + esterco de bovino, sendo as combinações em proporções de 50% de cada material) e quatro repetições. O trabalho foi realizado de setembro de 2004 a dezembro de 2005, em temperatura ambiente, na Embrapa Semi-Árido, em Petrolina, PE. Foram realizadas as avaliações aos 360 dias após o plantio. Em relação ao desenvolvimento do sistema radicular das cactáceas verificou-se que no substrato com aeia, todas as plantas apresentaram os maiores valores em termos de comprimento. O crescimento em altura das cactáceas foi influenciado pelos diferentes substratos analisados. Entre os substratos, o melhor foi o com solo + esterco de bovino, que provocou maior crescimento das plantas e a maior produção de matéria seca. |

The current Amazon landscape consists of heterogeneous mosaics formed by interactions between the original forest and productive activities. Recognizing and quantifying the characteristics of these landscapes is essential for understanding agricultural production chains, assessing the impact of policies, and in planning future actions. Our main objective was to construct the regionalization of agricultural production for Rondônia State (Brazilian Amazon) at the municipal level. We adopted a decision tree approach, using land use maps derived from remote sensing data (PRODES and TerraClass) combined with socioeconomic data. The decision trees allowed us to allocate municipalities to one of five agricultural production systems: (i) coexistence of livestock production and intensive agriculture; (ii) semi-intensive beef and milk production; (iii) semi-intensive beef production; (iv) intensive beef and milk production, and; (v) intensive beef production. These production systems are, respectively, linked to mechanized agriculture (i), traditional cattle farming with low management, with (ii) or without (iii) a significant presence of dairy farming, and to more intensive livestock farming with (iv) or without (v) a significant presence of dairy farming. The municipalities and associated production systems were then characterized using a wide variety of quantitative metrics grouped into four dimensions: (i) agricultural production; (ii) economics; (iii) territorial configuration, and; (iv) social characteristics. We found that production systems linked to mechanized agriculture predominate in the south of the state, while intensive farming is mainly found in the center of the state. Semi-intensive livestock farming is mainly located close to the southwest frontier and in the north of the state, where human occupation of the territory is not fully consolidated. This distributional pattern reflects the origins of the agricultural production system of Rondônia. Moreover, the characterization of the production systems provides insights into the pattern of occupation of the Amazon and the socioeconomic consequences of continuing agricultural expansion.
