| Among studies focused on increasing soybean grain yield, the ones related to sowing process are the most significant. Considering that soybean has an epigeal emergence, it becomes difficult to hint at the length covered by hypocotyl up to soil surface, or the actual planting depth. This study aimed to find an indicator that allows the identification of an ideal soybean planting depth. For this purpose, two complementary assays has been carried out in a greenhouse. The first aimed to identify structures that could be indicators of seed planting depth, on a medium-textured soil from Campos Gerais region, in the state of Paraná, Brazil. Spring NK 8350 cultivar seeds were sown at five theoretical depths (1, 2, 3, 4 and 5 cm). As seedlings emerged, the... |

| Irrigation with domestic sewage effluent (DSE) has been recommended by subsurface dripping, as it can obtain a high rate of irrigation efficiency and faster use of salts in comparison with other irrigation methods. The study aimed at evaluating the area, the length and the effective depth of the root system of sugarcane irrigated with DSE by subsurface drip system and with different irrigation rates at depths of 0.00-0.20, 0.20-0.40, 0.40-0.60 and 0.60-0.80m. The experiment was carried out in the municipality of Piracicaba, in the state of São Paulo (SP), Brazil, in a sugarcane area irrigated with DSE in a completely randomized blocks set up in furrows, with three replications and four treatments, which are: one area without irrigation (AWI) and three... |

| Para controle do fungo Ganoderma philippi é essencial detectar-se as plantas doentes no estagio em que elas comecam a exibir os primeiros sintomas (amarelecimento parcial das folhas). Em caso afirmativo, remover o solo ao redor do coleto e base das raizes laterais para confirmara ocorrencia da doenca (presenca de micelio do patogeno). Caso afirmativo, cortar e retirar as raizes afetadas e pincelar as restantes com pasta contendo Tridemorph, betume e querosene. Fazer a mesma inspecao em torno das plantas vizinhas e, se apresentarem fontes de infeccao, os tecidos lesionados devem ser eliminados e queimados. As raizes tangenciais, em relacao a planta doente de todas as arvores vizinhas, devem ser cortadas para evitar o alastramento da doenca. A seguir,... |

| Recentemente, foi observada um enfermidade em plantas de guarana, identificada como podridao vermelha da raiz. De isolamentos feitos das raizes parciais ou totalmente apodrecidas, conseguiu-se isolar o fungo Ganoderma philippii. Para controlar essa doenca, devem ser feitas inspecoes periodicas aos plantios, a fim de se detectar plantas atacadas. Quando encontrada alguma com sintoma da doenca (amarelecimento generalizado das folhas), deve-se proceder um exame em suas raizes. Se a pivotante estiver atacada e morta, a planta nao se recuperara e deve ser arrancada. Mas, se ainda nao foi atingida, aplicar, nas raizes mais longas, a partir do tronco, uma pasta formada da mistura de Tridemorph, betumen e querosene. Efetuar o mesmo tratamento nas plantas que se... |

| Os resíduos do sorgo-sacarino, pela liberação de substâncias alelopáticas, podem afetar negativamente o desenvolvimento da cultura em sucessão. Nesse contexto, objetivou-se avaliar os efeitos dos resíduos de duas cultivares de sorgo-sacarino na soja Semeada em sucessão, em função de intervalos para semeadura após o manejo do sorgo. O experimento foi conduzido em casa de vegetação na Embrapa Agropecuária Oeste, em Dourados, MS, em vasos com capacidade de 14 litros. O delineamento utilizado foi inteiramente casualizado, em esquema fatorial 2x4, com quatro repetições. Os tratamentos foram constituídos por duas cultivares de sorgo (BRS 506 e BRS 511) e quatro intervalos para semeadura da soja após manejo da gramínea (0, 3, 6 e 9 dias). As plantas de sorgo... |

| The total soil organic carbon (C) is regulated by climatic factors, altitude, texture and soil depth. Due to higher storage in surface, it is common to observe the exponential model to adjust the C content in the soil profile. This study was carried out in order to study the influence of climatic factors, altitude and soil depth on the vertical distribution (0-100 cm) of C in five Cerrado fragments located in the municipalities of Januária and Bonito de Minas, Minas Gerais State, Brazil. Soil samples were collected in the following layers: 0-10, 10-20, 20-40, 40-60 and 60-100 cm. The maximum and minimum levels of C varied depending on the sampling site, fragment and soil layer sampled. Larger variations in the levels of C were noted for the 0-10 cm layer,... |

| ABSTRACT: Verbascum L. is the largest genus of the family Scrophulariceae and includes several species are of medicinal importance. The high morphological diversity among the species of the genus Verbascum causes problems in the delimitation of the species. In this study, morphological, anatomical, palynological and seed properties of Verbascum exuberans were investigated. It is a local endemic restricted to the provinces of Manisa and Izmir in West Anatolia. In the root cross-section, the xylem elements occupy a considerable area. The upper part of the epidermis cells in the stem cross-section is covered a distinct cuticle layer. The main vein of the leaf is shapped as bicollateral bundle. Idioblasts were not observed in the epidermis of the leaves of V.... |

| The reduction in herbicide use is one of the greatest interests for modern agriculture and several alternatives are being investigated with this objective, including the adoption of cultivars that suppress weeds. The objective of this study was to verify if maize cultivars develop differently, in competition with weeds, to produce green ears and grain. Randomized complete block design was used, with split-plots and five replications. Cultivars DKB 390, DKB 466, DKB 350, AG 7000, AG 7575 and Master, were evaluated in the plots, without weeding and two weedings (at 22 and 41 days after sowing) in sub plots. Twenty-one species were identified in the experimental area, the most frequent being Gramineae (Poaceae), Euphorbiaceae, Leguminosae (Fabaceae) and... |
