| O presente trabalho teve o objetivo de avaliar o comportamento de cultivares de arroz de sequeiro em diferentes modalidades de preparo de solo e lâminas de água aplicadas por aspersão, no Município de Selvíria, MS. Os tratamentos consistiram na combinação de três cultivares de arroz (IAC 201, Carajás e Guarani), três sistemas de preparo do solo (arado de aiveca + grade niveladora, escarificador + grade niveladora e grade pesada + grade niveladora) e três níveis de irrigação por aspersão (sequeiro e duas lâminas de água), com quatro repetições. O uso da irrigação por aspersão reduziu o número de dias para o florescimento e o ciclo da cultura. A cultivar Carajás apresentou a maior produtividade de grãos e praticamente ausência de acamamento em relação às... |

| Dockage levels in U.S. wheat exports have been a continuing concern. Recent proposals have focused on changes in U.S. grain standards that would include dockage limits. In this report, dockage trends and practices were documented and effects of prospective changes evaluated. Results indicate the marketing system is currently working effectively with costs of extra cleaning being borne partly by buyers, elevators, and to some extent farmers. Suggested mandates would increase cleaning and result in increased costs (ultimately discounts to growers) and potentially in shifts in grades purchased. Proposed changes in grain standards are also a departure from the generally followed approach to regulation in the United States. In this case, a regulation is... |

| The 1986 U.S. Grain Quality Improvement Act introduced an explicit, economic purpose for grades-that they transmit information about end use value-but provided little guidance about what factors to include in grades. We determined which quality characteristics best reflect the processed value of U.S. corn in the case of a Japanese wet miller. Foreign material is the only grade factor closely related to processed value, but a large number of nongrade attributes, many of which reflect the intrinsic properties of corn, are found to vary substantially across shipments and to provide extensive information about value. Recommendations for U.S. grades are made. |

| Questions have emerged in the United States and Canada regarding the role and function of quality in international markets. One has been the definition and composition of different market segments, with a particular focus on higher quality customers. In this study, trends in U.S. wheat exports are analyzed by class, grade, protein, and market segment. Analysis shows trends toward increases in exports of higher grades of Hard Amber Durum (HAD) and Hard Red Spring (HRS); whereas, exports of higher quality grades for Hard Red Winter (HRW) appear to be moderate. Exports of HRS, HRW, and HAD show increases in proportion of exports shipped at higher protein levels and increases in the proportion of exports where protein is specified. Cluster analysis for... |
