Nutrient use efficiency (NUE) and Factors affecting nutrient use efficiency

Nutrient use efficiency (NUE) :

NUE may be defined as yield per unit input. In agriculture this
is usually related to the input of fertiliser, whereas in scientific literature the NUE is often
expressed as fresh weight or product yield per content of nutrient.
The nutrients most commonly limiting plant growth are N, P, K and S. NUE depends on
the ability to efficiently take up the nutrient from the soil, but also on transport, storage,
mobilization, usage within the plant, and even on the environment.

Factors affecting nutrient use efficiency :

1. Type of soil
2. Climate
3. Type of fertilizer
4. Time of fertilizer application.
5. Method of fertilizer application.
6. Quantity of fertilizer.
7. Nutrient’s interaction. Etc
