“…While, the wheat had a G of 22.25% and the white oat showed 47% of germinated seeds at the highest dose. Similar findings were reported by Erasmo et al (2004), who conducted a study in which a different species of velvet bean (Mucuna pruriens) was investigated, and a reduction in the number of weeds confirmed the control potential of this species.…”

Some plants can have a beneficial or harmful effect on the germination and growth of other plants. This is known as the allelopathic effect. The objective of this study was to evaluate the effect of different doses of velvet bean (Mucuna cineruim) aqueous extract on germination and initial seedling growth of three winter cereals: white oat (Avena sativa), rye (Secale cereale) and wheat (Triticum aestivum). The experimental design was a completely randomized design, with four replications of five doses of aqueous extract (0, 5, 10, 15 and 20%). Of the three cereals, rye had the greatest allelopathic effect on the test variables in the different aqueous extract concentrations, while the white oat had the highest mean germination time. Negative effects of velvet bean on the growth of wheat were observed only in the applications of high doses. It can be concluded that velvet bean exhibits great allelopathic potential to control the germination and seedling growth of the cereals. This effect was primarily observed in the white oat and rye under the applications of higher extract doses.

“…These results reinforce the importance of the presence of biomass on the soil surface, when sowing annual crops in the integrated weed management. Erasmo et al (2004) demonstrated the benefits of using biomass cover crops to control weeds within 60 days of desiccation, especially for Mucuna aterrima, and its effect as a physical and allelopathic barrier. (Figure 1), due to their high capacity to cover the soil and release allelochemicals, during the biomass decomposition.…”

Studies to identify potential cover crops species for the no-till system and minimal amounts of biomass required to reduce the emergence and development of weeds in cereal crop areas may represent an important tool in the integrated weed management. Thus, this study aimed at evaluating the inhibition of the emergence and growth of Bidens pilosa plants, using different cover crops biomass levels on the soil surface. The experiment was carried out in a greenhouse located in Bom Jesus, Piauí State, Brazil, from December 2011 to March 2012, in a randomized experimental blocks design with four replications, in a (5x6)+1 factorial scheme, consisting of six cover crop species and five biomass levels on the soil surface, plus a control with no soil cover. The species evaluated were Pennisetum glaucum (ADR 7010 and ADR 300 cultivars), Crotalaria ochroleuca, Urochloa ruziziensis (syn. Brachiaria ruziziensis), Crambe abyssinica and Fagopyrum tataricum, at five biomass levels corresponding to 4.0 t ha-1, 8.0 t ha-1, 12.0 t ha-1, 16.0 t ha-1 and 20.0 t ha-1. Urochloa ruziziensis and Fagopyrum tataricum were considered the best ones for controlling B. pilosa, with 4.0 t ha-1 of their biomass being sufficient to reduce the total number of emerged plants, germination speed index, shoot dry biomass, leaf area, root dry biomass and root volume of B. pilosa.

“…O intervalo de tempo entre a primeira e a segunda avaliação possibilitou o desenvolvimento vegetativo das plantas que já estavam emergidas na primeira avaliação, ampliando o seu acúmulo de matéria seca, assim como a emergência de novas plântu-las nesse intervalo de tempo. Na avaliação da interferência de oito espécies utilizadas como adubos verdes (Mucuna aterrima, Mucuna pruriens, Crotalaria ochroleuca, Crotalaria spectabilis, Canavalia ensiformis, Tabela 2 -Produtividade de matéria seca das culturas de cobertura (MSC), número total de plantas daninhas (NTPD) e matéria seca das plantas daninhas (MSPD) coletadas aos 15 e 30 dias após a emergência (dae) da cultura do milho, em resposta à presença Cajanus cajan, Pennisetum americanum e Sorghum bicolor, híbrido BR 304) sobre a comunidade infestante, verificou-se que C. spectabilis, S. bicolor, C. ochroleuca, M. aterrima e M. pruriens reduziram significativamente o número de plantas e o peso da matéria seca da população das plantas daninhas (D. horizontalis, H. lophanta e A. spinosus), principalmente as duas últimas (Erasmo et al, 2004).…”

RESUMO -O sombreamento do solo com cobertura morta proporciona redução na germinação das sementes e diminuição da população de plantas daninhas, possibilitando às plantas da cultura de interesse se desenvolverem sob efeito de menor competição inicial. Dessa forma, objetivou-se neste trabalho investigar o efeito do cultivo de leguminosas na evolução da comunidade de plantas daninhas na cultura do milho-verde cultivado em sucessão, num sistema orgânico. O ensaio foi realizado em delineamento em blocos ao acaso, com parcelas subdivididas e quatro repetições. Inicialmente, houve o plantio das leguminosas: feijão-deporco (Canavalia ensiformes), guandu (Cajanus cajan), mucuna-preta (Mucuna aterrinum), mucunaanã (Mucuna deeringiana) e crotalária (Crotalaria juncea); foi mantida uma testemunha sem cultivo em pousio. Anteriormente ao cultivo do milho, foi avaliada a produção de matéria seca de cada espécie de leguminosa. Em seguida, após a roçada das leguminosas foi semeado sobre a palhada o milho, cultivar HTMV 02. A amostragem das plantas daninhas foi realizada aos 15 e 30 dias após a emergência do milho, lançando-se de forma aleatória sobre cada parcela um quadro de 50 x 50 cm. As plantas daninhas dentro do quadro foram identificadas, pesadas e contadas por espécie, sendo posteriormente colocadas em estufa a 65 o C, por 72 horas, para determinação da matéria seca. As palhadas da mucuna-preta e da crotalária proporcionaram maior redução de matéria seca e população das plantas daninhas. A maior produtividade de espigas comerciais de milho-verde foi obtida na área de palhada de mucunapreta e crotalária.Palavras-chave: cobertura verde, cobertura morta, cobertura de solo, manejo cultural, Zea mays.ABSTRACT -Soil shading using mulch reduces weed seed germination and, consequently, weed population, allowing the plant of interest to develop free of the initial competition. Thus, the aim of this paper was to evaluate the effect of leguminous plant cultivation on the evolution of a weed community on green corn cultivated in succession under an organic system. The trial was conducted with leguminous plants during the 2007/2008 season, at the Embrapa Corn and Sorghum Field Center in Sete Lagoas-MG. The experiment was arranged in a completely randomized block design with split-plots and four replications, with five species of leguminous plants being evaluated: jack bean (Canavalia ensiformes), pigeonpea (Cajanus cajan), mucuna-black (Mucuna aterrinum), mucuna dwarf (Mucuna deeringiana) and Crotalaria juncea, plus a control, spontaneous vegetation of the area. On February/2008, the leguminous plants were cut close to soil and corn was planted over this mulch on March/06/2009. Weed samplings were collected at 15 and 30 days after corn emergence, which was randomly thrown on each plot framework, measuring 50 x 50 cm.. The weed plants within the framework were identified, weighed and counted. The results obtained showed that Mucuna aterrinum and Crotalaria juncea cover provided further weed biomass reduction during the two seasons eva...
