The supply of nitrogen (N) to the carioca bean plant via inoculation with Rhizobium tropici can prevent competition with the weed community by allowing the crop to absorb the nutrient available in the soil. On this basis, this study proposes to examine the period before weed interference (PBI) in the carioca bean plant following inoculation with R. tropici or N topdressing. The experiments were carried out under field conditions during the summer seasons of 2014 and 2015. A randomized-block experimental design with four replicates was adopted, in a 2 × 11 factorial arrangement (common bean plant inoculated or topdressed with N × 11 periods of coexistence with weeds, namely, 0, 7, 14, 21, 28, 35, 42, 49, 56, 63, or 90 days after emergence [DAE]). Nitrogen topdressing increased the crop's tolerance to coexist with weeds from 6 to 14 DAE, compared with inoculation with R. tropici The PBI for the inoculated common bean plant was 24 and 16 DAE in the years 2014 and 2015, respectively. For the N-topdressed plant, the PBI was 30 DAE in both years.

TENSÃO DE ÁGUA NO SOLO E DOSES DE NITROGÊNIO PARA A CULTURA DO FEIJOEIRO COMUM   Márcio José de Santana1; Amanda Letícia da Silveira1; Carlos Roberto de Camargos2; José Carlos Braga21Instituto Federal de Educação, Ciência e Tecnologia, Triângulo Mineiro, Campus  Uberaba, Uberaba, MG, [email protected] Universitário de Patos de Minas, Faculdade de Ciências Agrárias, Patos de Minas, MG   1 RESUMO Este experimento foi conduzido no campus II do Centro Universitário de Patos de Minas, MG, com o objetivo de avaliar o rendimento do feijoeiro comum, submetido a diferentes tensões de água no solo e doses de nitrogênio. Os tratamentos constaram de quatro tensões de água no solo (10 kPa, 30 kPa, 50 kPa e 70 kPa) e quatro doses de nitrogênio (50 kgha-1, 100 kg ha-1, 150 kg ha-1 e 200 kg ha-1). O delineamento foi em blocos casualizados, em esquema fatorial de 4x4 com três repetições. Foram avaliados: produtividade, número de vagens por planta, número de grãos não colhidos, número de vagens verdes e a eficiência do uso da água. Dentre os resultados pode-se constatar que a maior produtividade física foi verificada quando a irrigação foi efetuada com tensão de 22 kPa e dose de N de 130,5 kg ha-1; a maior eficiência do uso da água foi verificada quando a irrigação foi reposta com a tensão de 37 kPa. UNITERMOS: irrigação, tensiometria, eficiência da água.  SANTANA, M.J. de; SILVEIRA, A.L. da; CAMARGOS, C.R. de; BRAGA, J.C. SOIL WATER TENSION AND NITROGEN LEVELS FOR THE COMMON BEAN PLANT  2 ABSTRACT             This experiment was conducted in the Campus II of the Centro Universitário de Patos de Minas, MG, with the objective of evaluating the yield of common bean plant, submitted to different soil water tension and nitrogen levels. The treatments consisted of four water tension in soil (10 kPa, 30 kPa, 50 kPa e 70 kPa) and four nitrogen (50 kg ha-1, 100 kg ha-1, 150 kg ha-1 e 200 kg ha-1). The experimental design was randomized blocks in factorial scheme of 4x4 with tree repetitions. Crop yield, number of pod per plant, number of unharvested grains, number of green pods and water efficiency cropping were evaluated.  Among the results the physical productivity was when the irrigation was effectuated by tension of 22 kPa and N of 130.5 kg ha-1; the greatest  value for water use efficiency was irrigation tension of 37 kPa. KEYWORDS: irrigation, tensiometry, efficiency of water.

Among the nutrients, nitrogen (N) is the element required in greater quantity by the bean plant. Depending on the cultivar, it has greater or lesser N-fixing capacity. The aim of this work was to evaluate the performance of two common bean cultivars under nitrogen topdressing in corn succession, on yield components and yield. The experiment was carried out in randomized blocks in a 2x5 factorial scheme, the first factor being the common bean cultivars (IPR Campos Gerais and BRS Estilo) and the second factor the nitrogen rates (0, 30, 60, 90 and 120 kg ha- 1), with four repetitions. At harvest, plants were collected in one meter, in the useful area of ​​each subplot to determine: number of plants per meter; number of pods/plant; number of grains/plant; number of grains/pods; mass of a thousand grains and productivity. The cultivars differed regarding the number of pods per plant, grains per plant and yield, but they were equivalent for the number of plants per meter, grains per pod and mass of a thousand grains. Comparing the production component number of pods per plant and grain yield, it is concluded that the cultivar that produced the highest number of pods per plant and showed the highest yield was BRS Estilo. There were differences between the treatments for the two cultivars, only in the yield obtained. The highest yield averages were obtained in treatments with doses above 60 kg ha-1 of N.

Commercial cultivars of common bean (Phaseolus vulgaris) were screened for resistance to Tomato yellow leaf curl virus (TYLCV). Fourteen-day-old bean plants were inoculated with TYLCV by means of the whitefly vector (Bemisia tabaci). Following inoculation, plants were sprayed with an insecticide, kept in an insect-proof greenhouse for 4 weeks, and monitored for disease symptom development. The presence of viral DNA in the inoculated plants was assayed by dot blot hybridization and by polymerase chain reaction. Out of the 42 cultivars that were tested, 24 were found to be susceptible: the plants exhibited severe symptoms and accumulated high levels of viral DNA. In all, 18 cultivars were found to be resistant to the virus: 1 cultivar showed mild symptoms while the other 17 showed no symptoms following inoculation. From the 17 symptomless cultivars, plants of 3 cultivars contained viral DNA while no viral DNA was detected in the plants of the other 14 cultivars. When the effect of bean plant age on viral inoculation by whiteflies was assayed, it was found that the success rate of TYLCV infection was highly dependent on bean plant age. When 14-day-old susceptible bean plants were inoculated, nearly 100% infection was achieved but, when 26- or 12-day-old plants of the same cultivar were inoculated, the infection rates were only 34 and 40%, respectively.
