| The market for ornamental plants and flowers has been growing a lot in recent years, in the country, due to its importance in interior design. Petunias are seeded first in seedbeds and then replanted in plastic bags. In order to examine the potential use of biodegradable containers, an experiment was conducted at the experimental site of the Department of Natural Resources/Forestry Science, at Agronomics Sciences College of UNESP, Botucatu, São Paulo (Brazil), with common petunias (Petunia x hybrida) grown in greenhouses. The irrigation system used in the experiment was the spraying, without added nutrients. Four irrigations of approximately 15 minutes each were carried out every day, two in the morning and two in the afternoon, for irrigation. The... |

| A inoculação de culturas agrícolas com fungos micorrízicos arbusculares é uma prática agronômica promissora, que tem sido fortalecida pela recomendação de inoculantes recém-registrados no Brasil. A necessidade de entendimento de efeitos de diferentes formulações de inoculantes é, portanto, um aspecto fundamental para pesquisas de caráter básico e aplicado. O objetivo deste estudo foi avaliar o potencial de inóculo do fungo micorrízico arbucular Rhizophagus clarus cultivado no sistema de cultivo em vaso em relação ao sistema in vitro e testar o efeito de ambos no crescimento e produtividade da soja. O potencial de inóculo foi testado em condições de casa de vegetação, utilizando-se o milho como hospedeiro. Os valores de colonização radicular revelaram que o... |

| Located in western Paraná, the city of Palotina had begun it colonization in the late 50's and the city has undergone many changes where land with dense forest was almost totally occupied by crops. The increased population of approximately 4,000 people in 1960 to 30,000 in 2010 and currently has much of the economy based on agriculture and agribusiness. With the availability of climate data since 1972 the aim of this work was to identify changes and trends in the series of daily data of precipitation, air relative humidity, maximum, minimum and mean temperature, thermal amplitude and insulation in the city from 1973 to 2010. Linear regression and Mann-Kendall seasonal methods are applied. For the whole period can be inferred trend of decrease in relative... |

| The need to rationalize the use of fertilizers and other chemicals, and financial resources has generated, increasingly, research in order to describe the spatial variability of soil properties in crops. This study aimed to study the spatial organization of soil properties in a wheat seed production field in an area of 11 ha in Lavras do Sul, RS, Brazil. Collecting soil four subsamples for chemical analysis and 10 for compression using a 100m X 100m grid by sampling was performed. Descriptive analysis and geostatistical was performed to characterize the samples and identify the spatial dependence of the studied attributes. From the results obtained maps were drawn by "Agricultural System CR-Campeiro 7" software. The greater variability checked by... |

| The late season maize, intercropped with forage crops in tropical areas, is an alternative to grain production and straw maintenance in the no-tillage system. The objective of this study was to evaluate the agronomic performance of late season maize, intercropped with forage crops that were sown during the topdressing in phenological stage V5. The experiment was conducted in Sapezal, MT, (13º35'13'' S, 58º47'56'' W and altitude of 570 m). It was used a random block experimental design, with five treatments (monocropping of maize, maize + Urochloa brizantha Marandu, maize + Urochloa brizantha Piata, maize + Urochloa brizantha Xaraés and maize + Panicum maximum cv. Massai), with five repetitions. Plant height, height of insertion of the first spike, plant... |

O delineamento experimental utilizado foi inteiramente casualizado com quatro repetições. Os tratamentos constituíram-se das soluções de glyphosate (960 g ha-1) e 2,4-D (720 g ha-1) isolados e em mistura, além da adição dos adjuvantes Energic® e Joint Oil® nas concentrações de: 0; 0,1; 0,2; 0,3; 0,5; 0,75; 1,0; 1,5 e 2,0% (v v-1). Concluiu-se que o Energic® foi mais eficiente em reduzir a... |

| In commercial bananas there is an increasing increase for seedlings of high genetic quality and free of pathogens; thus, the use of micropropagation has been increasingly encouraged for the production of seedlings. However, the success of establishing these seedlings in the environment depends on several factors, in which, the substrate has a relevant role. The objective of this study was to evaluate the growth of micropropagated banana seedlings under the influence of different formulations of substrates based on soil, bovine manure and vegetable ash for organic production system. The experiment was carried out on a certified rural property under an organic production system in the municipality of Palmácia (CE). The experimental design used was completely... |

| The objective of this work was to study the consortium of corn with Brachiaria ruziziensis regarding the morphogenesis of the forage. The field experiment was conducted on November 2012 to April 2013, in an area of UNIOESTE, campus Marechal Cândido Rondon, Paraná State. The experimental design was randomized blocks in 2x3 factorial design, with three replications. The treatments consisted of two spacings (45 and 90 cm), conducted in three types of cultivation (B. ruziziensis; B. ruziziensis with corn in the row; and B. ruziziensis with corn between the row). The morphogenical characteristics evaluated were: rates of leaf appearance, leaf elongation, number of green leaves and leaf life span. The leaf elongation rate of B. ruziziensis cultivated alone was... |

| As cultivares de mandioca apesar de adaptarem-se aos mais diferentes ecossistemas, apresentam alta interação do genótipo com o ambiente. O seu cultivo restringe-se em grande parte em um sistema de revolvimento solo, que altera as propriedades físicas, química e biológica do solo. Diante do exposto, objetivou-se avaliar cinco cultivares de mandioca em dois sistemas de plantio, direto sobre palhada de aveia preta (SPD) e convencional com revolvimento do solo (SPC). O experimento foi conduzido durante a safra de 2016/2017 em Tuneiras do Oeste (Paraná). O delineamento experimental utilizado foi blocos casualizados, em esquema fatorial 5 x 2 [5 cultivares de mandioca, sendo IPR União, IAC 15, IAC 90, Baianinha e Olho Junto (Caiua) x 2 sistemas de plantio (SPD e... |

| Soil quality is a concern that every year becomes more and increasing current. With intensive farming worldwide, mainly in tropical countries, systems that aim at conservation of the chemical, physical and biological soil become a viable alternative for maintaining soil quality and sustainability of ambeinte. Thus, the objective of this work is to expose a revision that demostre the relationship of physical and chemical properties of soils that have different rates of organic carbon in the conditions of Cerrado in Brazil. For these environments the levels of soil organic matter - MOS and organic carbon - CO are associated and dependent on the rates of addition of waste and the intensity of the processes of decomposition of soil organic matter - MOS.... |

| This study aimed to evaluate the early growth stages of irrigated rice (Oryza sativa L.) seedlings from cultivars SCS-112, BRS-7 Taim, BR IRGA 410 and IRGA 417, under three different temperatures, i.e. 15, 20 and 25 °C, as a result of seed imbibition in a gibberellic acid (GA3) solution at concentrations of zero, 150, 300, 450, 600 and 750 mg L-1. The lengths of the shoot and the primary root of seedlings were recorded at three, seven and 21 days from sowings on germination paper. Interactions between the main factors were observed for all the response variables. Rice cultivars have differential sensitivity to variation in the concentration of gibberellic acid on seed treatment according to the temperature and the time of evaluation. Cultivar BRS-7 Taim... |

| O objetivo da pesquisa foi analisar a produção agrícola dos agricultores familiares do Assentamento Crajarí, que tem como principal característica, sistemas agroflorestais tradicionais ou técnicas agroecológicas. Esses sistemas são constituídos, na sua maioria, por cinco componentes: roça, capoeira (pousio), sítio (quintais), extrativismo e criação. A pesquisa foi desenvolvida no município de Benjamin Constant na região do Alto Solimões. Foi realizada no Assentamento Crajarí. Foram aplicadas vinte e duas entrevistas semiestruturadas, englobando aspectos: socioeconômicos, de produção, de comercialização e extrativismo. Os assentados possuem naturalidades diferentes, sendo a maioria do município de Atalaia do Norte. A mandioca (Manihot esculenta) é a espécie... |
