Description Usage Arguments Author(s) Examples

View source: R/LAI_function.R

Description

The LAI need in inputs the number of leaves, the leaf area (m^2),row distance (m) and in row spacing (m).

Usage

1
LAI_function(Number_of_leaves_by_plant, Leaf_Area, row_distance, in_row_distance)

Arguments

Number_of_leaves_by_plant

here need count the number of leaves of the plant.

Leaf_Area

here need calculate the leaf area, measured in m^2.

row_distance

the row distance of the orchard measured in meters.

in_row_distance

the in row distance or distance between plants of the orchard measured in meters.

## Should be DIRECTLY executable !! ----
## Here needed some inputs measured manually like leaf area (m^2) and number of leaves.
  number_of_leaves <- 420
  leaf_area <- 0.010 ## measured in m^2.
  row_distance <- 2.9 ## measured in meters.
  in_row_distance <- 1.4 ## measured in meters.

## The function is currently defined as
LAI_function <- function(Number_of_leaves_by_plant,Leaf_Area,in_row_distance){

 LAI <- Number_of_leaves_by_plant * Leaf_Area / in_row_distance

return(LAI)

  }
  LAI_function(number_of_leaves,leaf_area,in_row_distance)
