| ABSTRACT: The intensive use of plant protection products in rice paddy fields ( Oryza sativa L.) has caused concern about the environmental impact on communities of non-target organisms that are natural inhabitants in these agroecosystems. The purpose of this review is to analyze the data currently available in the literature about some important fungicides and insecticides (such as trifloxystrobin, tebuconazole, tricyclazole, lambda-cyhalothrin, and thiamethoxam), which are currently used to control pests and diseases in rice paddy fields, as well as their effects on the community of non-target aquatic organisms. |

| ABSTRACT Rice monoculture in lowlands can cause problems for management practices in crop fields, for example, in weed control. For this reason, corn in rotation with irrigated rice in lowlands may be advantageous, despite problems with soil compaction and water excess. The objective of this study was to evaluate soil physical properties and corn performance in soil management systems in an Albaqualf soil (lowlands). Two experiments were conducted in the field, in the 2013/14 and 2014/15 crop seasons. The experimental design was randomized blocks with two factors. There were three levels for the first factor, consisting of soil management practices: soil chiseling 45 days before sowing to a depth of 0.3 m; conventional tillage with two diskings to a depth... |

| Resumo: O objetivo deste trabalho foi avaliar o efeito de sistemas de plantio e irrigação suplementar em faixas sobre o rendimento de grãos de soja, em áreas com presença de camada compactada próxima à superfície do solo. Dois experimentos foram realizados em blocos ao acaso, em faixas, com quatro repetições, no Estado do Rio Grande do Sul. O experimento 1 foi realizado em Santa Maria, correspondente às safras de 2013/2014 e 2014/2015; e o experimento 2, em Formigueiro, na safra 2013/2014. Os tratamentos consistiram dos fatores A e D. O fator A considerou os seguintes sistemas de plantio: A1, semeadura com discos duplos desencontrados; A2, semeadura com disco ondulado de 12 ondas; A3, semeadura com haste sulcadora; A4, semeadura com haste sulcadora e um... |
