Conteúdo: |
Foram realizados estudos sobre o efeito do sulfentrazona no ganho de peso de ratas Wistar expostas a doses distintas do herbicida, durante períodos distintos de prenhez. As técnicas utilizadas para avaliar os efeitos dos fatores (fase de prenhez e dose de fungicida) e de suas interações na resposta foram modelo de medidas repetidas, LSD (Least Squares Difference) e técnicas de Comparações Múltiplas. |

Picture stories are being used for the most diverse purposes ranging from amusement to birth control. Their acceptance is admited to be very high, but only a few studies have tried to evaluate their potentialities as an aid for rural extension. The presente investigation employed picture stories to communicate technical information to small farmers, and also to determine what elements of presentation contribute to higher effectiveness. Among the independent variables were: age, education, prior experience with picture stories, literacy, and modernity of agricultural practices. The pictorial variables considered were background and illustration type. The dependent variable was recall. The basic assumption of the study was that the most effective illustration would be one that: (a) provides enough background to give the reader useful clues about the setting, but excludes background details that distract, confuse, and add no relevant information; (b) utilizes simple lines that are clearly defined, rather than gradations of tone and indistict boundaries. A picture story about seed quality on barley was developed and presented to 153 small farmers in eight localities of Hidalgo, Mexico, in one of the following treatments: (a) black and white photos with softened background; (b) black and white photos without background; (c) black and white line drawings; and (d) black and white shaded line drawings. Analysis of variance, correlation and regression analysis were performed and the results indicate that: (a) photos performed better than drawings; (b) photos with softned background got higher recall than photos without background; ;(c) simple line drawings did not differ statistically from shaded line drawings; (d) regardless of treatment, literacy level is the main variable "determining" recall; (e) age and ejidal area size were the other two variables affecting recall.
