Determinação de área mínima para aquisição de colhedora para a cultura do arroz irrigado na fronteira oestes do RS

Abstract

Rice harvesting is one most important operation in agriculture due to its high cost and value added. In this sense, the present work has objective carrying out a study of minimum area for acquisition a self-propelled harvester for irrigated rice crop. The work was carried out in Itaqui municipality, West Frontier Rio Grande do Sul, from data provided by dealer’s harvesters, more commercialized at region, being different brands harvesters and models equipped with axial track systems and hybrid types. Fixed and variable costs were analyzed by means mathematical equations known in literature, considering parameters related to particularities crop and region for determining minimum area. Results obtained on study allow us to conclude that minimum area that makes possible acquisition harvester for irrigated rice cultivation in western border region on state is 118.91 hectares.
