The study of weed interference periods and the economic threshold level (ETL) weeds on crops allows adoption management methods rationalized use herbicides. objective this was to determine test mathematical models ryegrass in wheat crop. Two experiments were carried out a randomized block design with four replications. first experiment conducted 2014/2015 agricultural season. control studied wheat. and/or were: 0, 10, 20, 30, 40, 50 120 days after emergence (DAE). second 2016/2017 ETLs...
The crop yield is related to several factors, among these, soil tillage, compaction and rotation. This study aimed evaluate the winter cover crops rotation influence on physical properties grain of dry beans, maize soybean for two growing seasons. Three experiments were conducted, corresponding crops. It was used randomized block design with three treatments four replications consisted by 3 × 10 m plots. were: systems in no-till, control, consisting fallow conventional tillage. matter,...

Este trabalho apresenta uma análise de séries temporais dos dados temperatura mínima e máxima mensal da cidade Erechim, RS; apresenta-se comparação duas classes modelos tradicionais previsão, nomeadamente: classe ARIMA alisamento exponencial. Na foram selecionados, utilizando-se critérios informação, do tipo SARIMA, que consideram a característica sazonal ar; já para os exponencial utilizaram-se Holt-Winters aditivo, em as constantes são determinadas forma minimizar o erro quadrático médio...
The present study examined the influence of Hydroelectric Power Plant (HPP) Passo Fundo dam lake on local rainfall pattern. Daily data were obtained from National Water Agency for two different periods: prior to filling, 1960-1970 (pre-filling) and later 1971-1981 (post-filling). Statistical measures (mean, maximum, minimum, standard deviation coefficient variation) Student’s t-test applied both periods regarding monthly total. Student's was also days with cumulative greater than 1 mm, 10 20...
Este trabalho analisou o comportamento do fenômeno ENOS no Alto Uruguai gaúcho utilizando dados de precipitação dos municípios Erechim, Quatro Irmãos e Erebango. Foram utilizados pluviométricos diários da Agência Nacional Águas (ANA), Fundação Estadual Pesquisa Agropecuária (FEPAGRO) Instituto Meteorologia (INMET). As falhas existentes foram preenchidas com uso regressão linear simples, verificadas sua consistência pela Curva Dupla Massa. Os valores anuais comparados informações sobre a...
Currently the soybean crop is responsible for a great share of protein consumed by humans and animals, it also source oil renewable materials industry. Due to importance soybeans worldwide, especially genetically modified (resistant glyphosate - GR), improvement in yield indexes became targets promising research. The objective this work was evaluate responses “GR” as function herbicide foliar fertilizer, under soil without nutrient deficiency. experiment conducted randomized block design...
The crop systems adopted in the Amazônia region have been studied several times terms of variability and to indicate soil attributes more sensitive different crops. Thus, objective this work was apply multivariate techniques order identify chemical most environmental changes Western Amazonia, Brazil. research conducted five rural properties located Humaitá city region, There were selected four environments with natural characteristics (Native Forest - NF) cropping (Grazing, Cassava, Açaí,...
Uma série temporal consiste em um conjunto de dados qualquer fenômeno observados ordenadamente. Análise séries temporais aplicadas a meteorológicos tem atraído especial interesse nos últimos anos devido à influência exercida pelo clima, sobretudo na agricultura. O presente trabalho realizou estudo uma precipitação Erechim (RS) no período 2003 2011 buscando encontrar modelo mais adequado previsão. A inclusão covariáveis (temperatura máxima e mínima Normal Climatológica precipitação)...
Solanum americanum Mill. is a weed that occurs with number of crops, and it known for its high seed production staggered germination. The objective this work was to evaluate the germination behavior S. seeds under influence chemical environmental factors. In laboratory, we tested effect on (i) constant alternating temperatures, (ii) washing, (iii) exposure time concentration treatments (iv) seeding depth soil covered plant residue seedling emergence. variables analyzed were percentage, rate...
Lowlands have been cultivated with irrigated rice (Oryza sativa) in a monoculture cropping system for more than century southern Brazil. Shallow topsoil high bulk density and deficient water infiltration favors the of production paddy rice; however, this condition does not favor species non-tolerant to flooding or oxygen restriction. Thus, soil irrigation management may be necessary raise rice-soybean (Glycine max) rotation systems sustainable levels. We carried out two-year field experiment...

The seeds physiological quality is a fundamental characteristic to obtain competitive and productive plants, where treatment an important tool keep high-quality.The present study aimed evaluate chemical treatments storage period influence on quality.It was used factorial (4 x12) randomized complete block design, with eight replications.In factor A, the chemicals (thiamethoxam, metalaxyl + fludioxonil thiabendazole pyraclostrobin thiophanate-methyl fipronil) control.In B, treated periods (0,...
The soil and vegetation characteristics of the southern Amazonas region include highly weathered soils, high aluminum content some hydromorphic conditions, its is composed from grasslands to small isolated trees forest galleries along rivers streams. In this way, work aims characterize classify in areas clean field, dirty Humaitá AM. Soil trenches were opened environments, profiles morphologically characterized, samples collected their horizons. Physical analysis texture, dispersed clay...
