Run a first experiment of irrigation planning for a sugarbeet crop in Porto-Novo

[akouete-kpakpo]

I have this plot for the variety 601 of sugarbeet crop

Unsatisfying as:

• insensitivity to irrigation event date: when I change date of month for the only irrigation event, I have exactly the same plot, the difference between the 2 plots should start at event date with a lag, intuitively
• insensitivity to water volume: when I change the water volume from 0.01 cm to 10 cm, I have exactly the same plot
• I don't have the same level of leaf area index as in Allard's tuto: my LAI ranges in 0 - 0.2 whereas his lies in 0-7

Have to understand why

When i did my first simulation of sugarbeet based on the notebook of Allard I have the same level of leaf area index as Allard. I could say the fact that you don't have the same thing as Allard is due to the parameters of crop.

thanks for your suggestion @Ethel2003 . Indeed, my previous plot shows a sugarbeet simulation in Lome. But in Allard's tuto, the crop locates in Wageningen, Netherlands. This is what I have by fixing the location: now I have the same range of values for the leaf area index as in the tuto notebook

The difference is explained by the rain intensity during the crop (source of data plotted: NASA Power database)

Lome, Togo

Wageningen, Netherlands

I think that

root zone soil moisture

is more explicit than

Leaf area index

to correlate crop ecosystem evolution with irrigation events

[Ethel2003]

Okay. It is more comprehensible

solved in #36

it was a config bug. Now all good
