| The silvicultural and economic potential of paricá (Schizolobium amazonicum) has encouraged the expansion of this crop, mainly in the northern region of the country, provoking the need for studies on the species. The objective of this study was to estimate paricá production in Paragominas region, Para State, Brazil, at 5, 6 and 7 years, in three classes of productivity considering five plant arrangements, being identified the main costs of production, in addition to those most affected by plant arrangements. The volumetric estimation was obtained by modeling in population level and the analysis of the costs, through the methodology of the operational cost. It was possible to infer that the arrangement of plants 3 m x 2 m was superior in volume, compared to... |

| This study results from a two years' intensive research into a hitherto unexplored area of irrigation management - the aspect of financing irrigation in some Asian countries. The authors have analyzed the relationship between investment costs, level of irrigation fees, cropping intensity, type of crop, and secondary income. The studies conclude that the quality of irrigation system operations and maintenance is affected not only by the amount of resources made available to operate and maintain systems, but also by the institutional arrangements under which they are provided. |
