yield_parameters {growR} | R Documentation |
The dataset contains the parameters a and b used to model the expected gross dry matter yield (in t / ha) as a function of altitude (in m.a.s.l.) as yield = a + b * altitude.
yield_parameters
A data.frame with 4 rows and 3 variables:
Management intensity
Offset a in t / ha
Slope b in t / ha / m
Lookup Table of expected yield as functions of height and management intensity after table 1a in Olivier Huguenin et al.
