-The aim of this paper was to conduct the phytosociological survey of weeds in cultivated areas with common beans and castor beans in the municipality of Ipameri, in the Southeast region of the State of Goiás, considering intercropping and monoculture. The survey was conducted 20 days after emergence of the crop using the square inventory method. We evaluated the green and dry biomass of weeds, their leaf area, frequencies, density and absolute and relative dominance, relative importance and similarity index, expressed as a percentage. Sixteen weed species were identified, distributed into 10 botanical families. The most important weed species in the Southeast region of Goiás for the cultivation of common beans and castor beans were: Cenchrus echinatus, Euphorbia heterophylla, Alternanthera tenella, Eleusine indica and Urochloa decumbens. The weed community shows a high level of similarity between intercropping and monoculture for castor bean and common bean crops. Keywords: Phaseolus vulgaris, Ricinus communis, intercropping, phytosociology.

Resumo: A presença de animais nos sistemas de integração lavoura-pecuária (ILP) é causa de preocupação para produtores no que se refere à compactação do solo. Objetivou-se, com este trabalho, avaliar as características agronômicas da cultura de soja cultivada sob plantio direto em área de ILP preparada ou não com descompactador "matabroto". O experimento foi conduzido na safra agrícola 2013/2014, na área experimental pertencente à Fazenda Santa Brígida, município de Ipameri, Goiás. O delineamento experimental foi de blocos inteiramente casualizados com dois tratamentos e dez repetições. Os tratamentos estudados foram constituídos de dois métodos de preparo do solo (T1=sem matabroto e T2=com matabroto Ikeda 30 dias antes da semeadura, com profundidade de 35 cm). Foram avaliadas as seguintes características: estande final de plantas, altura de inserção da primeira vagem, altura das plantas, comprimento da raiz principal, número de vagens por planta, número de hastes por planta e produtividade. Os resultados obtidos foram submetidos à análise de variância e ao teste t de Student, a 5% de probabilidade. Os diferentes tipos de preparo de solo não surtiram efeito para as características de estande final, altura de inserção da primeira vagem, altura de planta, número de hastes por planta e número de vagens por planta. Entretanto, a utilização do matabroto promoveu incremento no comprimento da raiz principal, o que provavelmente resultou em melhor aproveitamento de água e nutrientes pela planta, proporcionando maior produtividade de grãos, quando comparada à não utilização do matabroto em área sob plantio direto.

The objective of this work was to evaluate the agronomic characteristics of soybeans cultivated under a no-tillage system in the crop-livestock integration area, which was prepared with and without the use of a "matabroto" decompressor. The experiment was conducted in the agricultural crop of 2013-2014, in the experimental area belonging to Fazenda Santa Brígida, in the municipality of Ipameri, Goiás, Brazil. The experimental design included completely randomized blocks with two treatments and ten replicates. The treatments were composed of two methods of soil preparation (T1=without matabroto; and T2=with matabroto Ikeda 30 days before sowing, with a depth of 35 cm). The following characteristics were evaluated: final plant stand, first pod insertion height, plant height, main root length, number of pods per plant, number of stems per plant, and productivity. The results were submitted to a variance analysis and Student's t-test at a probability of 5%. The different types of soil preparation had no effect on the characteristics of the final stand, first pod insertion height, plant height, number of stems per plant, and number of pods per plant. However, the use of matabroto promoted an increase in the length of the mai...
