The control of spontaneous plants is one of the biggest challenges faced by organic no-tillage system (NTS). Thus, the use of cultural practices that help on it becomes relevant. The objective of this research was to evaluate the population density, the level of infestation and fresh and dry weight of
spontaneous plants community of the green corn cultivated in organic NTS. The trial was conducted in a randomized block design, with six replications and five treatments, consisting of three soil coverings in the organic NTS and organic and conventional systems using intensive soil tillage without covering. For soil covered treatments was used millet as grass specie and sunn hemp as leguminous specie as well as the intercropping between both species. The green corn (AG 1051 hybrid) was sowed at 1.0 m. between rows and 0.20 m. between plants. Infestation, density and fresh weight and dry weight evaluations of spontaneous plants were performed on the V5 (five developed leaves) stage of corn. The use of single millet straw and intercropped straw provided a reduction of the infestation percentage and absolute spontaneous plants density. Both organic and conventional intensive soil tillage systems without covering showed higher relative density for the specie Galinsoga quadriradiata. The highest relative densities in organic NTS were attributed to Amaranthus spp., C. rotundus and Oxalis spp.. The percentage of infestation by spontaneous plants did not reach the level of economic damage in any of the treatments studied since the average productivity of ears without straw had been within the Brazilian average (9,000 to 15,000 Kg ha MenosThe control of spontaneous plants is one of the biggest challenges faced by organic no-tillage system (NTS).

O objetivo deste trabalho foi avaliar a resistência quantitativa de 13 genótipos de conilon que compõem a variedade clonal Conilon Vitória Incaper 8142 com a raça II de H. vastatrix. Três mudas de cada genótipo foram inoculadas com a raça II monopustular de H. vastatrix pelo método do pincel no delineamento inteiramente casualizado. Os seguintes componentes de resistência foram avaliados: 1) Período de Incubação (PI), 2) Período Latente (PL), 3) Produção de Esporos (PE), 4) Área Foliar Lesionada (AFL), 5) Produção de Esporos por Área Foliar Lesionada (PEAFL), 6) Área Foliar Esporulada (AFE), 7) Produção de Esporos por Área Foliar Esporulada (PEAFE), 8) Severidade da Doença (SEV), 9) Frequência de Infecção (FI) e 10) Número Total de Pústulas (NTP). A técnica estatística multivariada de Componentes Principais (CP) foi usada para interpretação dos dados. Com esta técnica foram definidos quatro grupos de resistência das plantas: resistentes, moderadamente resistentes, moderadamente suscetíveis e suscetíveis à raça II de H. vastatrix. As plantas mais resistentes a esta raça, avaliando conjuntamente os 10 componentes de resistência foram os clones 1V, 2V, 3V e 4V do Conilon Vitória.
The aim of this study was to evaluate the quantitative resistance of 13 genotypes conilon comprising the clonal variety Conilon Vitória Incaper 8142 with race II of H. vastatrix. Three seedlings of each genotype were inoculated with race II single-uredinial of H. vastatrix by the method of brush in a randomized design. The following components of resistance were evaluated: 1) Incubation Period (PI), 2) Latent Period (PL), 3) Production of Spores (PE), 4) Diseased Leaf Area (AFL), 5) Production of spores per injured leaf area (PEAFL), 6) sporulating leaf area (AFE), 7) Spore production by sporulating leaf area (PEAFE), 8) Severity of Disease (SEV), 9) Frequency of Infection (FI) and 10) Total Number of Pustules (NTP). The Principal Component Analysis (PC) was used for data interpretation. With this technique were defined four groups of plant resistance: resistant, moderately resistant, moderately susceptible and susceptible to race II of H. vastatrix. An overall analysis with the 10 components of resistance identified clones 1V, 2V, 3V and 4V of Conilon Vitória as the most resistants to this race.
