cane: Sugar-cane Disease Data
Description
The cane data frame has 180 rows and 5 columns.
The data frame represents a randomized
block design with 45 varieties of sugar-cane and 4 blocks.source
The data were kindly supplied by Dr. C.G.B. Demetrio of Escola
Superior de Agricultura, Universidade de Sao Paolo, Brazil.Details
The aim of the experiment was to classify the varieties into
resistant, intermediate and susceptible to a disease called "coal of
sugar-cane" (carvao da cana-de-acucar). This is a disease that is
common in sugar-cane plantations in certain areas of Brazil.
For each plot, fifty pieces of sugar-cane stem were put in a solution
containing the disease agent and then some were planted in the plot.
After a fixed period of time, the total number of shoots and the number
of diseased shoots were recorded.References
