To maximize the contribution of biological nitrogen fixation in common bean, it is necessary to use bacterial strains that are more adapted, competitive, and efficient in the symbiotic process. In this regard, the aim of this study was to evaluate the agronomic efficiency (AE) of three bacterial strains isolated from acid soils with high Al content from the Amazon region in an Argissolo Vermelho Distrófico típico soil (Typic Rhodustults - USDA Classification) from the municipality of Formiga, MG, Brazil. We compared their AE to that of the reference strain CIAT 899T and of two controls without inoculation (one without and another with 80 kg ha-1 of N-urea). The results indicated that inoculation with the strains UFLA 02-100 and UFLA 02-127 provides grain yield equivalent to inoculation with the reference strain and to the control with mineral N. Thus, both have potential for recommendation as inoculants for common bean. © 2017 Instituto Nacional de Pesquisas da Amazonia. All rights reserved.

The objective of this study was to analyze technically and economically the irrigated ‘Gália’ melon (Hybrid Nectar), cultivated in greenhouse with and without using plastic mulch covering on the soil. Simultaneously, two experiments were conducted using a completely randomized design (CRD), in which melon plants were submitted to five water availability levels, defined by 50, 75, 100, 125, and 150% of crop evapotranspiration, with four replicates. The difference between experiments were only about the soil covering with plastic mulch: with (CC) or without (SC) plastic mulch. The economically optimal irrigation depths were 208.83 and 186.88 mm, resulting in yields of 50.85 and 44.51 t ha-1 for the experiments with and without mulching, respectively. The results showing the economically optimal irrigation depths were very close to those that produced the highest yield. © 2017 Departamento de Engenharia Agricola - UFCG/Cnpq. All rights reserved.

Arsenic (As) is the one of the main environmental pollutant and phytoremediation is an effective tool for its removal of the environment. In this study, Pistia stratiotes were exposed to seven As concentrations (0, 3, 7, 10, 13, 16 and 20 μM) and then, the influence of this metalloid on growth, mineral nutrition and photosynthesis were analyzed. It was observed that this species have a high affinity for As and pollutant uptake occurs rapidly. The uptake of Cu, Mn, Fe and P increased until the concentration of 13 μM, decreasing in higher concentrations.The Mg content also decreased from this same concentration. No effects were observed in the uptake of K, Ca and Zn. Growth rate and photosynthetic pigments content were negatively affected by As. Despite this decrease, the growth was maintained up to the concentration of 13 μM of As. The maintenance of growth and the change in nutrients uptake are probably related with the increase in antioxidant capacity of the plant, indicating resistance to the pollutant. In this way, P. stratiotes is probably an efficient phytoremediator of As, even when in concentrations up to one hundred times greater than those permitted in water for human consumption.

Some epidemiological aspects of leishmaniasis in the municipality of Formiga, Brazil, an important touristic site, were evaluated. Those included phlebotomine sand fly vectors, canine infection, and geoprocessing analysis for determining critical transmission areas. Sand flies (224 insects) belonging to ten different species were captured. The most captured species included Lutzomyia longipalpis (35.3%), Lutzomyia cortelezzii (33.5%), and Lutzomyia whitmani (18.3%). A significant correlation between sand fly densities and climatic conditions was detected. Serological diagnosis (DPP and ELISA) was performed in 570 dogs indicating a prevalence of 5.8%. After sequencing the main species circulating in the area were Leishmania infantum and Leishmania braziliensis. Spatial analysis demonstrated that vegetation and hydrography may be related to sand fly distribution and infected dogs. The municipality of Formiga has proven leishmaniasis vectors and infected dogs indicating the circulation of the parasite in the city. Correlation of those data with environmental and human cases has identified the critical areas for control interventions (south, northeast, and northwest). In conclusion, there is current transmission of visceral and canine human cases and the city is on the risk for the appearance of cutaneous cases. © 2015 Júlia Alves Menezes et al.

Introduction: Leishmaniasis represents an important burden of diseases in tropical countries, with significant levels of morbidity and mortality where they occur, including in Brazil. In this context, popular participation in prophylactic actions can be decisive for the success of the control strategies. Objective: For this reason, this study aimed at investigating the population’s knowledge concerning leishmaniasis and the occurrence of peridomiciliary risk factors associated with the population of Formiga, Minas Gerais. Methods: A household questionnaire with a sample of 427 individuals was conducted between May and July 2011. Results: Only 7.5% of the residents presented knowledge regarding leishmaniasis, most of them being women (OR = 3.15; 95%CI 1.30 – 7.65). The prevalence of peridomiciliary risks was 95%. A statistically significant association was found between higher education levels and less peridomiciliary risk factors (OR = 0.45; 95%CI 0.28 – 0.72) and between the place of residence and a higher number of risk factors (OR = 0.84; 95%CI 1.19 – 2.85). Conclusion: The results demonstrate that the population has low levels of knowledge about leishmaniasis. Moreover, the majority of respondents are subject to some peridomiciliary risk factor, which may contribute to the maintenance of the disease cycle in the city. © 2016, Assocaicao Brasileira de Pos, Gradacao em Saude Coletiva.

Introduction: Children are always involved in physical activities and team sports. Thus, studies that combine physical performance and cardiorespiratory fitness are necessary to encourage and implement health promotion actions. Objective: To evaluate the response of physical performance and cardiorespiratory indicators in the spontaneous interruption of a maximum progressive test in children. Method: Prospective, analytical, observational and cross-sectional study. One hundred and six children with a mean age of 10.2 ± 1.1 years participated in the study. Weight and height were obtained to determine the body mass index and the cardiorespiratory fitness was evaluated by the maximum progressive Léger test. The observed variables were heart rate, respiratory rate, peak forced expiratory flow, maximum oxygen volume, and abdominal muscle strength. The children were divided according to their performance in the maximum progressive test, a group achieving up to 280 meters and a group achieving over 280 meters. Result: The mean value of body mass index was 17.8 kg/m2and the maximum oxygen volume was 40.5 mlO2/kg-1.min-1. The group that reached the greater distance in the maximum progressive test had a lower body mass index (p=0.002), a higher speed (p=0.000), a longer time in the physical effort (p=0.000), higher maximum oxygen volume (p=0.000), and a greater abdominal muscle strength (p=0.007). The variables heart rate, respiratory rate and peak flow had values expected for age with no difference between groups. The group that reached the greater distance had a correlation with speed (r=0.950, p<0.000) and with oxygen volume (r=0.740, p<0.000). In contrast, the shorter distance group had a higher correlation with body mass index (r=-0.475, p=0.000) and respiratory rate (r=0.585, p<0.674). Conclusion: Children with a lower body mass presented better performance in the maximum progressive test, and girls stood out for the greater time of physical effort without increasing the maximum oxygen uptake. © 2017, Redprint Editora Ltda.

Infusions of the leaves and seeds of Annona crassiflora Mart. are commonly employed in the treatment of diarrhoea, snakebites, tumours and disorders of the hair and scalp. The aim of the present study was to investigate the cytotoxic and genotoxic properties of ethanolic extracts of A. crassiflora by evaluating their effects on germination, root elongation, chromosome structure and the cell division of Lactuca sativa (lettuce). The experiment followed a randomized design involving the treatment of L. sativa seeds with ethanolic extracts from leaves and seeds of A. crassiflora applied at ten concentrations (0. 0125, 0. 025, 0. 05, 0. 1, 0. 2, 0. 4, 0. 6, 0. 8, 1. 0, and 1. 2 mg/L) and with five repetitions per treatment. Seeds of L. sativa exposed for 48 h to A. crassiflora leaf extract at concentrations ≥ 0. 1 mg/L, or to seed extracts at concentrations ≥ 0. 2 mg/L, showed germination percentages that were significantly (p < 0. 05) lower than those of seeds exposed to aqueous ethanol control. Exposure of L. sativa seedlings to leaf (but not seed) extracts of A. crassiflora produced significant (p < 0. 05) reductions in the mitotic indices of root meristem cells of lettuce and induced chromosome and nuclear abnormalities in the root cells. The presence of chromosome stickiness, bridges, fragments, laggard chromosomes and nuclear condensation were also observed. The cytogenetic effects observed suggest that folkloric medicines prepared with extracts of the leaves or seeds of A. crassiflora should be employed with caution. © 2013 Versita Warsaw and Springer-Verlag Wien.

Coffee Science | Year: 2016

The coffee yield is strongly influenced by adequate supply of water and nutrients to plants. Because not all soil is the ideal amount of nutrients for plant growth, fertilization is intended to supplement these nutrients. The nole of fertigation is to provide coffee the water volume to be supplied with nutrients and preventing entering the plant water stress and nutrition. This study was carried out in the experimental area of the Department of Agriculture, Universidade Federal de Lavras in coffee cultivar Catigua MG 3 plants spaced 2.5 × 0.60 m. We tried to raise the detachment force of fruit maturation in green and cherry fruit moisture, trying to verify if these parameters correlate with the status of plants, over the period of maturation and consequently the selective mechanical harvesting. It was concluded that the oscillations of the detachment force of the coffee cherry are related to variables of the soil. The alterations found in fruit detachment force are observed when changes occur in soil moisture and soil water tension. © 2016, Editora UFLA. All rights reserved.

Hydrological models have been increasingly employed for evaluation of pollution caused by diffuse sources in watersheds. In this study, the Soil and Water Assessment Tool (SWAT) was used to simulate streamflow and suspended sediment concentration (SSC) at the Lavrinha Creek watershed (LCW) outlet, which is situated in the Mantiqueira Range region in Minas Gerais State, Brazil. Temporal series associated with climatic variables, streamflow, and SSC were obtained from existing hydrological monitoring that has been conducted in the LCW since January 2006. Eight months (January 2006 to August 2006) were chosen as the warm-up period for the SWAT model, while two years (September 2006 to August 2008) were considered for model calibration and two years (September 2008 to August 2010) for model validation. A statistical index, Nash-Sutcliffe efficiency (NSE), was employed to evaluate the model performance. Streamflow simulations with SWAT on a daily basis resulted in NSE values of 0.81 and 0.79 for the calibration and validation periods, respectively; when simulating sediment concentration, the model resulted in NSE values of 0.68 and 0.75 for the calibration and validation periods, respectively. The SWAT model was considered adequate to simulate streamflow and SSC at the LCW outlet, thus constituting an important tool for water resources management in the Mantiqueira Range region. © 2013 American Society of Agricultural and Biological Engineers.
