ABSTRACT: The morpho-physiologic characteristics of common bean plants can affect their competitive ability with weeds. The objective of this work was to evaluate the competitive ability of black bean genotypes with weeds. An experiment was carried out in the 2010/ 11 cropping season in Papanduva, SC, southern Brazil, in order to verify the variability of some plant characteristics among genotypes of common bean. The randomized block design was used, with four replications. Seven cultivars underwent the treatments: BRS Campeiro, CHP 01-238, CHP 01-239, Diamante Negro, BRS Supremo, BRS Valente, IPR Uirapuru, FTS Soberano, IPR Graúna, IPR Tiziu e IAC Diplomata. At 6, 14, 18, 25 and 32 days after emergence (DAE) were evaluated plant height, ground cover by common bean plants, dry biomass of stems and leaves, and grain yield. In the 2011/12 cropping season the same cultivars were grown in the presence or absence of weeds, adopting similar methodology to the 2010/11. The losses of grain yield in black common bean genotypes due to weed interference ranged from 30.8% to 54.9%. There was a positive correlation between yield reduction promoted by the weed infestation and dry biomass produced by the weeds. In addition, there was a positive correlation between percentage of yield reduction due to the weed infestation and grain yield without weed interference. The characteristics evaluated did not estimate the competitive ability of black common bean genotypes with weeds. RESUMO: As características morfofisiológicas de plantas de feijão podem afetar a habilidade competitiva com plantas daninhas. Neste trabalho, objetivou-se avaliar a competitividade de genótipos de feijão do grupo ?Preto? com plantas daninhas. Inicialmente, foi conduzido um experimento na safra 2010/11 em Papanduva, SC, para verificar a variabilidade entre genótipos de feijão-preto quanto a algumas características da planta. Foi utilizado o delineamento experimental de blocos casualizados, com quatro repetições. Os tratamentos foram constituídos pelos seguintes genótipos: BRS Campeiro, CHP 01-238, CHP 01-239, Diamante Negro, BRS Supremo, BRS Valente, IPR Uirapuru, FTS Soberano, IPR Graúna, IPR Tiziu e IAC Diplomata. Aos 6, 14, 18, 25 e 32 dias após a emergência (DAE) foram determinadas altura das plantas, cobertura do solo pelas plantas de feijão, massa seca de hastes e folhas e, ao final do ciclo, a produtividade dos grãos. Na safra 2011/12, os mesmos genótipos foram avaliados na presença ou ausência de plantas daninhas, adotando metodologia similar à da safra 2010/11. As perdas de produtividade de grãos dos genótipos de feijão avaliados, em razão da interferência de plantas daninhas, variaram de 30,8 a 54,9%. Houve correlação positiva entre porcentagem de redução de produtividade em razão da infestação e a massa seca acumulada pelas plantas daninhas. Também houve correlação positiva entre porcentagem de redução de produtividade em função da interferência de plantas daninhas e a produtividade sem infestação. Não foi possível identificar características de plantas que afetam significativamente a habilidade dos genótipos de feijão em competir com plantas daninhas.

The soymilk is a ready-to-eat, nutritious and naturally cholesterol-free product. Several soybean specialty cultivars were developed in Brazil in order to increase the human consumption of soybean products. The aim of this work was to evaluate the nutritional composition and consumer acceptance of soymilk from three soybean cultivars with special features such as high-protein and isoflavone contents, mild flavor and lipoxygenase-free compared to three conventional ones. The soymilk was obtained after blanching with a bicarbonate solution, grinding, centrifugation and pasteurization. The physicochemical and nutritional evaluation data were analyzed using Analysis of Variance (ANOVA) and Tukey?s test to check differences among means, and the consumer data through cluster analysis and internal preference mapping. The lipoxygenases were inactivated after thermal processing. There were significant differences among soybean cultivars and soymilks related to the protein, isoflavones, oil, and sugar contents and soymilk yield (p < 0.05). The BRS 133 and BRS 284 cultivars and soymilks presented the highest total isoflavone content (p < 0.05). Regarding the overall consumer acceptance, there were significant differences among cultivars (p < 0.05) with means ranging from 5.9 to 6.7 and the lower score was obtained by BRS 267. However, the cluster analysis identified three consumer segments according to preference similarity. The cultivars BRS 284 and BRS 267 reached the highest mean among the consumers of segment 1 (6.8 and 6.7 respectively). The consumers of segment 2 preferred the cultivar without lipoxygenases, BRS 213 (mean of 7.5) while segment 3 preferred the BRS 133 (mean of 7.4). The process of blanching of soybean with bicarbonate solution, grinding with boiling water and pasteurization mitigated the differences between conventional and specialty cultivars and the six cultivars evaluated were suitable for soymilk production.
