How to Calculate Water Requirement for your Crops while using Emitters/ Drippers in Drip Irrigation?
calculation for water requirement in drip irrigation drippers in drip irrigation emitters in drip irrigation formula to calculate water requirement in drip Irrigation water requirement for crops
First we need to calculate the total water required. Let’s seen an example:
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
So, we need 40m3 / hr water to irrigate 1.5 ha of cotton crop using emitters in drip irrigation.
