“…This decrease, although it has not been studied, can be explained by some adversity, especially by slip on the planter wheels in treatments with tillage. These results corroborate with those found by CRUZ et al (2009) that working with the cultivation of maize, single and intercropped with Brachiaria decumbens in tillage systems: conventional (double plow and double disking), minimum tillage (one plowing and one disking) and no-tillage (no soil mixing ), no significant differences in plant population was found.…”

“…ALMEIDA et al (2008) found, after three years of installation of soil management systems, the effects of rotation with green manure, corn or soybean (summer) and beans "winter", that systems of crop rotation, cover crops and management of the soil influence the physical and chemical properties of soil and crop productivity bean, corn and soybeans. Similar results were found by CRUZ et al (2009), obtaining better chemical soil conditions and higher grain yield of corn in minimum tillage and no-tillage systems.…”

ABSTRACT:The evaluation of technologies employed at the agricultural production system such as crop rotation and soil preparation, both associated with crop-livestock integration, is crucial. Therefore, the aim of the present study was to evaluate the incorporation of lime for three no-tillage systems and cultural managements in system of crop-livestock integration, with emphasis on corn grain yield. The experiment was conducted from January 2003 to April 2005 at Selvíria city, MS, in Dystroferric Red Latosol, clay texture. The experimental design was randomized blocks with split plots consisted of three main treatments, aimed the soil physics conditioning and the incorporation of lime: PD -No-no-tillage; CM -minimum no-tillage, and PC -conventional no-tillage; and of two secondary treatments related to the management: rotation and crop succession, with four replications. Data on agronomic traits of maize were analyzed: plant height, stem diameter, height of the first spike insertion, 100 grains weight and grain yield. The results showed that the maize produced under the system of croplivestock integration is quite feasible, showing that grain yields are comparable to averages in the region and the different soil physical conditioning and incorporation of lime did not influence the corn yield as well as the cultural managements, rotation and succession, did not affect the maize crop behavior after two years of cultivation.

“…In the present study, this is due to the use of reduced inter-row spacing (0.50 m) and the consequent early ground cover, which helped in the crop control of Brachiaria. These results are lower than those observed in other studies on maize and Brachiaria intercropping (Jakelaitis et al, 2005;Cruz et al, 2009;Adegas et al, 2011); however, they corroborate other research, in Table 2 -Number of plants, number of tillers and dry matter of shoot of the Brachiaria intercropped with maize and submitted to the application of glyphosate doses in stages of two and four tillers, compared to control without application…”

Glyphosate Herbicide Use in Urochloa brizantha Management in Intercropping With Herbicide-Resistant Maize

et al. 2016

The success of the intercropping among cultivated species depends on the adoption of practices that provide, in due course, greater competitive ability of a species over another. The objective of this study was to evaluate the use of glyphosate herbicide in the suppression of Brachiaria (signalgrass) intercropped with maize. The experiment was conducted in a randomized complete block design with four replications. The treatments were arranged in a 5 x 2 + 2 factorial arrangement, the first factor corresponding to the doses of glyphosate (48, 96, 144, 240, 480 g ha-1 of the acid equivalent (a.e)) and the second one to the vegetative stages of the signalgrass at the time of application (2 and 4 tillers). Two controls were added to the treatment list, comprising controls without herbicide application and hand removal of the signalgrass. The number of plants, tillers and dry matter of signalgrass was reduced with glyphosate. The increase of the glyphosate doses enhanced the injure to the forage plants, mainly when the compound was sprayed at the two-tiller vegetative stage. The dry matter of maize plants increased proportionally to the glyphosate dose. However, the height of the maize plants was not affected. The grain mass and productivity of maize grain increased with increasing dose of glyphosate. The maize yield was negatively influenced on the untreated control. Glyphosate at 96 and 144 g ha-1, when applied at 2 and 4 tiller stage, respectively, reduces the growth of signalgrass and does not affect the maize grain yield.

Este trabalho teve como objetivo avaliar os indicadores de eficiência técnica e econômica da produção de milho, em três variações de manejo em sistema plantio direto (lavoura com apenas adubação mineral -PDM; lavoura com adubação mineral e orgânica -PDO e integração lavoura e pecuária -PDI) e suas relações com os atributos físicos e químicos do solo. O estudo foi realizado em lavouras de sete municípios do Estado de Santa Catarina, determinandose os custos de produção e os indicadores técnicos e econômicos das culturas. Em cada lavoura selecionada, foram coletadas, em três pontos equidistantes, amostras para avaliações dos atributos químicos e físicos do solo na camada de 0-10 cm. Os dados foram submetidos a análises univariada e multivariada. Os resultados indicaram que o sistema PDM apresenta os maiores custos de produção, enquanto o PDO apresenta os melhores resultados econômicos e de eficiência de produção. Não foram observados efeitos significativos dos diferentes manejos, em sistema plantio direto, sobre os atributos químicos e físicos do solo. Contudo, a análise multivariada possibilitou mostrar, de modo mais amplo, as relações entre as variáveis estudadas e os diferentes manejos, em sistema plantio direto.Palavras-chave: custos de produção; adubação orgânica; integração lavoura-pecuária. This study aimed to evaluate the technical and economic efficiency indicators of the production of corn in three management variations in no-tillage system (tillage, with mineral only fertilization -PDM; tillage, with mineral and organic fertilizing -PDO; and integrated crop-livestock -PDI) and their relationship with physical and chemical attributes of the soil. The study was conducted in corn crops located in seven cities in the state of Santa Catarina, determining the cost of production and the technical and economic indicators of culture. In each selected crop, composite samples were collected, in three equidistant points, for the evaluation of chemical and physical attributes of the soil at a depth of 0-10 cm. The data were subjected to univariate and multivariate analyses. The results indicate that the PDM system presents the highest production costs, while the PDO offers the best economic results and productive efficiency. No significant effects were observed in the different managements in no-tillage systems on soil chemical and physical attributes. However, multivariate analysis made possible to show, more broadly, relations among the variables studied and different management in no-tillage systems.
