The objective of this work was to evaluate the common bean response to N application timing, under no-tillage system, after single corn or intercropped with palisade grass. A randomized complete block experimental design was used in a split-plot arrangement, with four replicates. Plots consisted of: single corn crop or corn intercropped with palisade grass, in two summer cropping seasons precedent to common bean sowing. Subplots consisted of: 100 kg ha-1 N application in three times - before sowing, at sowing, and at side-dressing - and a control treatment without N application. Nitrogen fertilization on common bean increased leaf-N content, the number of pods per plant, and grain yield (33% in the average application timing), only in the cropping after single corn. By providing large mass production and by N cycling, the cultivation of palisade grass intercropped with corn reduced N requirement of common bean in succession, in comparison to previous sole corn cultivation. Early N application before or during common bean sowing time provides grain yield similar to the observed one in the side-dressing application.

Ocorrência de plantas daninhas em cultivo consorciado de café e nogueira-macadâmia

Arborization can benefit coffee plantations by reducing the wind speed and temperature variation in the crop. It is also possible that the incident radiation can affect the weed populations and reduce the need for their control. This study aimed at assessing the weeds population and distribution, in arabica coffee intercropped with three macadamia cultivars, six years after planting, in Dois Córregos, São Paulo State, Brazil. Treatments consisted of a 3x3+1 factorial scheme, i.e., coffee intercropped with three macadamia cultivars (HAES 816, IAC 4-20 and IAC 9-20) and three sampling positions of weeds in the intercropping (in the macadamia tree canopy projection, among the macadamia tree canopies projections and in the single rows), plus an additional treatment (sole coffee). The weeds incidence and control, as well as their phytosociological characterization, were evaluated. For coffee intercropped with macadamia, the weeds occurrence and number of species were smaller than for sole coffee. For the projection in the canopy and among canopies of macadamia trees, there was an average decrease of 82% in the occurrence of weeds, in comparison with the sole coffee. The IAC 9-20 cultivar was more efficient in reducing the occurrence of weeds, when intercropped with coffee, for presenting a taller canopy, with a larger diameter.

Prevalence and risk factors associated with wheezing in the first year of life

Objective: to investigate the prevalence and risk factors associated with wheezing in infants in the first year of life.Methods: this was a cross-sectional study, in which a validated questionnaire (Estudio Internacional de Sibilancias en Lactantes - International Study of Wheezing in Infants - EISL) was applied to parents of infants aged between 12 and 15 months treated in 26 of 85 primary health care units in the period between 2006 and 2007. The dependent variable, wheezing, was defined using the following standards: occasional (up to two episodes of wheezing) and recurrent (three or more episodes of wheezing). The independent variables were shown using frequency distribution to compare the groups. Measures of association were based on odds ratio (OR) with a confidence interval of 95% (95% CI), using bivariate analysis, followed by multivariate analysis (adjusted OR [aOR]).Results: a total of 1,029 (37.7%) infants had wheezing episodes in the first 12 months of life; of these, 16.2% had recurrent wheezing. Risk factors for wheezing were family history of asthma (OR = 2.12; 95% CI: 1.76-2.54) and six or more episodes of colds (OR = 2.38; 95% CI: 1.91-2.97) and pneumonia (OR = 3.02; 95% CI: 2.43-3.76). For recurrent wheezing, risk factors were: familial asthma (aOR = 1.73; 95% CI: 1.22-2.46); early onset wheezing (aOR = 1.83; 95% CI: 1.75-3.75); nocturnal symptoms (aOR = 2.56; 95% CI: 1.75-3.75), and more than six colds (aOR = 2.07; 95% CI 1.43-.00).Conclusion: the main risk factors associated with wheezing in Fortaleza were respiratory infections and family history of asthma. Knowing the risk factors for this disease should be a priority for public health, in order to develop control and treatment strategies. (C) 2013 Sociedade Brasileira de Pediatria.
