| ABSTRACT This study aimed to evaluate the behavior of soybean plants subjected to irrigation management with controlled water deficits in different phenological stages. The research was conducted in an experimental area of the Federal University of Tocantins (UFT), in Palmas-TO, Brazil. The experimental design was randomized blocks with four replicates, and treatments arranged in a split-plot scheme. The plots consisted of irrigation levels that induced plants to water deficit in the vegetative stage, reproductive stage and throughout the entire cycle, based on potential crop evapotranspiration (ETpc). The subplots corresponded to two soybean cultivars (M9144RR and TMG1288RR). The following agronomic variables were evaluated: days until flowering, days... |

| Cultivares de soja (Glycine max (L.) Merril), mais utilizados no Rio Grande do Sul para produção de grãos, foram testadas visando a produção e qualidade do feno. O experimento foi estabelecido no Departamento de Zootecnia da UFSM, em solo pertencente a Unidade de Mapeamento São Pedro (Podzólico Vermelho Amarelo), textura média. As cultivares BR-2, Paraná, IAS-5, Planalto, IAS-4, CEP-12, Bragg, BR-4, Bossier, Santa Rosa, BR-1, Cobb, foram agrupadas em delineamento de blocos ao acaso com quatro repetições. O corte foi realizado no estádio de início de formação de grãos (R5), deixando as plantas no campo até murcha completa e, posteriormente, fenado a galpão. Foram analisados matéria seca (MS), digestibilidade in vitro da matéria seca (%DIVMS) e proteína... |

| ABSTRACT Plant Growth Promoting Rhizobacteria (PGPR) have different mechanisms of action in the development of plants, such as growth promotion, production of phytohormones and antibiotic substances and changes in root exudates. These help to control plant diseases. In order to evaluate the potential of microorganisms in the control of Meloidogyne javanica and Ditylenchus spp., five rhizobacteria isolated from rhizosphere of garlic cultivated in the Curitibanos (SC) region were tested. Hatching chambers were set on Petri dishes, in which were added 10 mL of bacterial suspension and 1 mL of M. javanica eggs suspension, at the rate of 4500, on the filter paper of each chamber. The same procedure was performed with 300 juvenile Ditylenchus spp. The... |

| ABSTRACT The objective of this study was to determine the dual crop coefficient of an early-cycle soybean cultivar for the city of Tangará da Serra, MT, Brazil, using high-precision lysimeters. The method used was the dual crop coefficient (dual Kc) of FAO Bulletin 56, constitued by soil evaporation coefficient (Ke), determined by microlysimeters, and by basal crop coefficient (Kcb), determined by weighing lysimeters. Reference evapotranspiration (ETo) was calculated using the Penman-Monteith equation. Soybean sowing and harvesting were performed in the 2015/16 season with spacing of 0.45 m between rows. The reference evapotranspiration (ETo) estimated for the cultivation period was 267.06 mm; the crop evapotranspiration was 323.61 mm throughout its cycle.... |

| Três experimentos de campo e um em vasos foram conduzidos com a cultura da soja 'Santa Rosa', para estudar os efeitos da aplicação de diferentes herbicidas, combinados com diferentes populações de plantas, sobre a nodulação, produção de grãos e teor de N em grãos. Utilizaram-se solos argiloso e muito argiloso no campo e argiloso e barrento em vasos. Os herbicidas aplicados foram o trifluralin a 0,96 kg/ha e o vernolate a 3,60 kg/ha, incorporados ao solo; alachlor a 2,40 kg; pendimethalin a 1,50 kg em dois experimentos e a 1,25 kg em um e o metribuzin a 0,63 kg em dois e a 0,53 kg em um em pré-emergência no campo. Em vasos, as doses foram as mesmas, exceto do trifluralin, que foi de 0,86 kg. Havia um tratamento sem herbicida em cada experimento. As... |

| The aim of this study was to assess the effects of the sources and levels of surface-applied (broadcast) phosphorus (P) when sowing the winter annual forages on phosphorus accumulation and yields of maize, soybean, black oat and annual ryegrass crops in a crop-livestock integration system over three years. The experiment was established in April 2009, in the municipality of Castro, Parana, Brazil. The treatments consisted of the broadcast application when sowing the winter forages of four doses (0, 60, 120 and 180 kg ha-1 year-1) of total P2O5 as triple superphosphate (TSP), rock phosphate (RP-Arad) and magnesium termophosphate (MTP). The dry matter yields of black oat (2009 and 2011), annual ryegrass (2010), maize (2009/10 and 2011/12) and soybean... |

| The effect of metolachlior [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-l-methylethyl) acetamide] at rates of 0.0, 1.5, 3.0, 4.5, and 6.0kg a.i./ha on the growth and nodulation of soybean cv. BR-4 cultivated on two substrata (soil and soil + sand) and inoculated with Bradyrhizobium japonicum (Kirchnea-1896) Jordan 1982, 137 (Denotes that this name has been validly published in the oficial publicadon, Intemational Joumal of Systematic Bacteriology), was studied under greenhouse conditions at Lages, SC, Brazil, in 1992-93. The experimental design was completely randomized with four replicates. The experimental unit was a container with two plants. Fifty-two days after the emergence (at R1 stage - beginning of flowering) the plants were harvested and... |

| This study aimed to characterize the harvest phenological stages of soybean cultivars intended for silage. Cultivars were evaluated for dry weight of the composite sample, branches, leaves and pods; wet mass of branches, leaves, pods and ground natural matter. This experiment was a 3 x 2 factorial randomized block design, with four replications each, where the first factor corresponds to the harvest stage: R4, R5 and R6; and the second factor refers to two soybean maturity groups (8.0 and 8.1). A significant interaction was detected only for ground natural matter. Higher values of most traits evaluated were observed for the R6 harvest phenological stage. The cultivar with maturity group 8.0 showed higher values for ground natural matter. |

| A soja constitui, atualmente, assunto de intensa atividade de pesquisa dirigida para a obtenção de informações que possibilitem aumentos de produtividade. Nesse contexto, a utilização de sementes de alta qualidade constitui-se em uma ferramenta de extrema importância para o agricultor. Com o objetivo de avaliar o efeito do vigor na produtividade da soja, seis lotes de sementes, três de alto e três de baixo vigor foram semeados, utilizando-se três densidades de semeadura, determinadas pela germinação do termo de conformidade, mais um fator de correção de 15% e pelo resultado da emergência no campo. A população de plantas após a emergência não foi alterada com desbaste, buscando assim, reproduzir as condições de campo que o agricultor enfrenta com a... |
