yield_parameters {growR}R Documentation

Parameters for expected yields in Switzerland

Description

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.

Usage

yield_parameters

Format

A data.frame with 4 rows and 3 variables:

intensity

Management intensity

a

Offset a in t / ha

b

Slope b in t / ha / m

Details

Lookup Table of expected yield as functions of height and management intensity after table 1a in Olivier Huguenin et al.
