Seed survial data of three crops - groundnut, soybean and wheat stored for 15 years at combinations of three different moisture contents (3%, 5% and 7%) and temperatures (0 °C, 10 °C and 25 °C).
seedsurvival
A data frame with 7 columns:
The crop name.
The moisture content (%).
The temperature (°C).
The period of storage, i.e. the year at which viability was recorded.
The replication.
The viability percentage value recorded.
The sample size used for estimating viability percentage.
