The image above represents application efficiency for trickle irrigation.

To compute for application efficiency for trickle irrigation, two essential parameters are needed and these parameters are **Emission Uniformity (E _{u}) **and

**Application Efficiency for Sprinkler (E**

_{a}**).**

The formula for calculating application efficiency for trickle irrigation:

E_{ta} = E_{u} x E_{a} x 100

Where:

E_{ta} = Application Efficiency for Trickle Irrigation

E_{u} = Emission Uniformity

E_{a} = Application Efficiency for Sprinkler

Let’s solve an example;

Find the application efficiency for trickle irrigation when the emission uniformity is 32 and the applicatio efficiency for sprinkler is 4.

This implies that;

E_{u} = Emission Uniformity = 32

E_{a} = Application Efficiency for Sprinkler = 4

E_{ta} = E_{u} x E_{a} x 100

E_{ta} = (32) x (4) x 100

E_{ta} = 12800

Therefore, the **application efficiency for trickle irrigation **is **12800%.**

**Calculating for the Emission Uniformity when the Application Efficiency for Trickle Irrigation and the Application Efficiency for Sprinkler is Given.**

E_{u} = ^{Eta} / _{Ea x 100}

Where;

E_{u} = Emission Uniformity

E_{ta} = Application Efficiency for Trickle Irrigation

E_{a} = Application Efficiency for Sprinkler

Let’s solve an example;

Find the emission uniformity when the application efficiency for trickle irrigation is 60 and the application efficiency for sprinkler is 2.

This implies that;

E_{ta} = Application Efficiency for Trickle Irrigation = 60

E_{a} = Application Efficiency for Sprinkler = 2

E_{u} = ^{Eta} / _{Ea x 100}

E_{u} = ^{60} / _{2 x 100}

E_{u} = ^{60} / _{200}

E_{u} = 0.3

Therefore, the **emission uniformity **is **0.3%.**

**Calculating for the Application Efficiency for Sprinkler when the Application Efficiency for Trickle Irrigation and the Emission Uniformity is Given.**

E_{a} = ^{Eta} / _{Eu x 100}

Where;

E_{a} = Application Efficiency for Sprinkler

E_{ta} = Application Efficiency for Trickle Irrigation

E_{u} = Emission Uniformity

Let’s solve an example;

Find the application efficiency for sprinkler when the application efficiency for trickle irrigation is 48 and the emission uniformity is 4.

This implies that;

E_{ta} = Application Efficiency for Trickle Irrigation= 48

E_{u} = Emission Uniformity = 4

E_{a} = ^{Eta} / _{Eu x 100}

E_{a} = ^{48} / _{4 x 100}

E_{a} = ^{48} / _{400}

E_{a} = 0.12

Therefore, the **application efficiency for sprinkler **is **0.12%.**
