Modeling by multiple enchained imputation is an area of growing importance. However, its models and methods are frequently developed for specific applications. In this study the model for multiple imputation was used to estimate daily rainfall data. Daily precipitation records from several meteorological stations were used, obtained from system AGRITEMPO for two homogenous climatic zones. The precipitation values obtained for two dates (Jan. 20th 2005 and May 2nd 2005) using the multiple imputation model were compared with geo-statistics techniques ordinary Kriging and Co-kriging with the altitude as an auxiliary variable. The multiple imputation model was 16% better for the first zone and over 23% for the second one, compared to the rainfall estimation obtained by geo-statistical techniques. The model proved to be a versatile technique, presenting coherent results with the conditions of different zones and times. |

Soybean rust caused by Phakopsora pachyrhizi is one of the most important diseases in the world, being identified by the first time in Brazil in may/2001 at Paraná state. Since its occurrence in Paraná, soybean rust has spread very fast to other states of Brazil. During 2001/2002 summer crop, soybean rust was not identified at Federal District and Tocantins state, but it was identified at five counties at Goiás state. During 2002/2003 summer crop, soybean rust was identified at Federal District, Tocantins and in more than fifty counties of Goiás state. During 2003 winter crop Phakopsora pachyrhizi was identified at Formoso do Araguaia area (Tocantins state) in soybean fields irrigated by water table elevation, and at Goiás, Mato Grosso and Maranhão state under fields irrigated by central pivot. From 501 soybean cultivars and 2023 lines evaluated for resistance to Phakopsora pachyrhizi, none showed resistance to this fungus, but differences in severity were observed among lines and cultivars. |
