Management information for BRILHANTE wheat trials in Brazil

A dataset with management information derived from EPAMIG experimental trials in Brazil, filtered for the cultivar BRILHANTE. These data were processed in `data-raw/reference_egypt.R`.

Usage

management_brazil

Format

A data frame with one row per planting period × year, containing:

crop

character. Crop name (always `"wheat"`).

variety

character. Cultivar name (always `"BRILHANTE"`).

sowingDOY

integer. Sowing date expressed as day-of-year (DOY).

year

integer. Growing season year.

planting_period

integer. Planting period index within each year.

Details

These records were derived from EPAMIG trial data (`data-raw/data_epamig.csv`) by summarising heading, harvest, disease severity, and yield across replicates, then extracting only the sowing information relevant for management simulation.
