“…Aguyoh & Masiunas (2003) reported that snap bean yield was reduced by 13%-58% at densities 0.5-8 of redroot pigweed plants per meter, respectively. Vogt et al (2013) reported that the losses of grain yield in black common bean genotypes due to weed interference ranged from 30.8% to 54.9%.…”

-To evaluate the effect of planting date and spatial pattern on common bean yield under weed-free and weed-infested conditions, an experiment was conducted in Kelachay, Northern Iran, in 2013. The experimental design was a randomized complete block in a factorial arrangement with three replicates. Factors were planting date (10 August and 20 August), spatial pattern (square and rectangular planting pattern, with a planting distance of 30 x 30 cm and 45 x 20 cm, respectively), and weed management regime (weed-free and weedy conditions, weeded and not weeded throughout the growing season, respectively). Results showed that the main effect of planting date was significant only for pod number per plant and seed number per pod. At the same time, pod number per plant, seed number per pod, pod length, and grain yield were influenced significantly by spatial pattern. Results of ANOVA have also indicated that all traits, except pod length, were influenced significantly by weed-management regimes. Moreover, effect of planting date and spatial pattern were nonsignificant for weed dry weight. Mean comparison has expressed a significant increment in seed yield for square planting arrangement (1,055 kg ha ). Weeding has also presented an overall 12% and 8% improvement in grain and pod yield over control (weedy check), respectively. Based on the results of this study, weed control, as well as square planting pattern, are recommended for obtaining the highest seed yield in common bean.

The common bean has been considered to have low biological nitrogen fixation capacity; however, this process can be made more effective with molybdenum (Mo) supplementation. The objective of this study was to evaluate the influence of Mo rates on the growth and biological nitrogen fixation by two Brazilian common bean cultivars using the 15N isotope dilution technique. The experiment was performed in 2014 in a completely randomized design arranged in a 5 x 3 factorial scheme, corresponding to 5 rates of Mo (control, 40, 80, 120 and 240 g ha-1), the common bean cultivars Aporé, Ouro Negro and NORH-54 (a non-nodulating common bean cultivar), and three replicates. The application of Mo and the inoculation with rhizobia strains contributed to improving nitrogen fixation and grain weight. The cultivar Ouro Negro showed a higher number and weight of nodules and a higher amount of nitrogen derived from the atmosphere than the cultivar Aporé. The biological nitrogen fixation of Aporé was more dependent on the application of Mo. These results indicated that inoculation with Rhizobium strains and Mo supply effectively contributed to biological nitrogen fixation and improving grain production.

“…Carioca and Preto beans correspond to around 85% of the Brazilian bean market (Ribeiro et al, 2014). Other types of beans are important regional foods, including the Fradinho bean (cowpea), which is popular in Northeastern Brazil, representing approximately 10% of the total Brazilian dry bean market (Vogt et al, 2011).…”

-Aspergilli are common contaminants of food and feed and a major source of mycotoxins. In this study, 87 Aspergillus strains were isolated from beans from 14 different cities in Brazil and identified to the species level based on partial calmodulin and β-tubulin sequence data. All green spored isolates belonged to section Flavi and were identified as A. flavus (n=39) or A. pseudocaelatus (n=1). All black spored isolates belonged to section Nigri and were identified as A. niger (n=24) or A. luchuensis (n=10), while the yellow spored strains were identified as A. westerdijkiae (n=7), A. ostianus (n=3), A. ochraceus (n=1) or A. wentii (n=2). The toxigenic potential of these Aspergillus strains from beans was studied by the prospection of genes in three of the major mycotoxin clusters: aflatoxin (seven genes checked), ochratoxin A (four genes) and fumonisin (ten genes and two intergenic regions). Genes involved in the biosynthesis of aflatoxin were only detected in A. flavus isolates: 17/39 A. flavus isolates proved to contain all the aflatoxin genes tested, the others missed one or more genes. The full complement of fumonisin biosynthesis genes was identified in all A. niger isolates. Finally, no genes for ochratoxin A were detected in any of the isolates. Our work suggests that aflatoxin production by some A. flavus strains and fumonisin production by A. niger isolates form the largest mycotoxin risks in Brazilian beans.
