Tres cultivares de Panicum maximum Jacq. foram avaliados ao longo do ano quanto ao tamanho de bocados, estimado utilizando-se bovinos esofago-fistulados e tambem por meio da divisao do consumo de forragem diario pelo numero de bocados realizados por dia. Os tratamentos constituiram em: 1) cv.Tanzaniacom adubacao nitrogenada, 2) cv Tanzaniza sem adubacao nitrogenada, 3) cv. Mombaca e 4) cv Massai, avaliadas em junho, setembro e novembro de 1998 e marco de 1999. Maiores tamanhos de boicados ocorreram no inicio do periodo chuvoso, associados a maiores proporcoes de folha verde e melhor qualidade do pasto. O tamanho de bocado foi em geral menor no trtamento cv. Massai, o que pode ser atribuido a maior proporcao de material morto e a distribuicao generalizada deste material ao longo do perfil da pastagem. Os valores para tamanho de bocado com o uso de animais fuistulados foram superestimados. |

Abstract. The severity of plant diseases, traditionally the proportion of the plant tissue exhibiting symptoms, is a key quantitative variable to know for many diseases and is prone to error. Good quality disease severity data should be accurate (close to the true value). Earliest quantification of disease severity was by visual estimates. Sensor-based image analysis including visible spectrum and hyperspectral and multispectral sensors are established technologies that promise to substitute, or complement visual ratings. Indeed, these technologies have measured disease severity accurately under controlled conditions but are yet to demonstrate their full potential for accurate measurement under field conditions. Sensor technology is advancing rapidly, and artificial intelligence may help overcome issues for automating severity measurement under hyper-variable field conditions. The adoption of appropriate scales, training, instruction and aids (standard area diagrams) has contributed to improved accuracy of visual estimates. The apogee of accuracy for visual estimation is likely being approached, and any remaining increases in accuracy are likely to be small. Due to automation and rapidity, sensor-based measurement offers potential advantages compared with visual estimates, but the latter will remain important for years to come. Mobile, automated sensor-based systems will become increasingly common in controlled conditions and, eventually, in the field for measuring plant disease severity for the purpose of research and decision making.
