- •
Nitrogen concentration of fodder beet assessed under variable water and N supply.
- •
The crop critical nitrogen (Nc) dilution curve was described by Nc = 4.9 W−0.52.
- •
Nitrogen Nutrition Index (NNI) of fodder beet ranged from 0.60 to 1.74.
- •
This model can be used to assess N status of fodder beet crops.
