5. Compute Indicators Using Indicators Calculator Tab
5.7. Yield
We'll calculate now the Yield.
1.
In the
Indicator Selection
dropdown, select
Yield
.
Formula
:
Y = HI * AOT * fc * (TBP / (1 - MC))
Parameters for Oued Hellal:
MC
: 0.15 (Moisture content, dry matter over fresh biomass)
fc
: 1.46 (Light use efficiency correction factor)
AOT
: 0.85 (Above ground over total biomass production ratio)
HI
: 0.48 (Harvest Index)
Note: These parameters are specific to the type of crops that are grown in the study area.
2.
In the
Formula Parameters
, select the
Total Biomass Production raster
(
WH_TBP_2022_10_01
).
3.
Enter the above parameters and name the output file
WH_Yield_2022_10_01
.
4.
Click
Calculate Indicator
. The output raster will be saved and loaded into QGIS.
