How to Calculate Water Requirement for your Crops while using Emitters/ Drippers in Drip Irrigation?


First we need to calculate the total water required. Let’s seen an example:
How to Calculate Water Requirement for your Crops while using Emitters/ Drippers in Drip Irrigation?

Consider we have 1.5 ha area and going to grow a cotton crop in the spacing of 1.5 m x 0.50m.  We are going to use inline dripper having a discharge capacity of 2 LPH (litres per hour so how to calculate the water requirement in drip irrigation?

Taking the given parameters,

We need to calculate how many plants are there in a given area?

Convert ha to sq.meter

1.5 x 10,000 = 15000 Sq.meter

Then,

=15000 / 1.5 x 0.5 (crop spacing)

= 20000 plants can be planted in the field

Now,

We are going to provide 2 litres of water to each plant, so
Total Water Requirement = 20000 x 2 (Total plants x dripper discharge )
=40000 litres or 40 m3/hr
