Question

why drip irrigation is not used by all farmers

Answer 1

drip irrigation is not used by all farmers because it is very costly and it it's want a lot of labour to fix all the pipe in the field as well as it needs a proper tank setup to give water to the plants

Answer 2

The reasons why farmers use one irrigation system over another are varied and sometimes complex. Each form of irrigation has pros and cons that make it more or less appropriate for any particular farm and any given crop. It's worth a look at different irrigation systems to understand why drip systems, despite their reputation for water efficiency, aren't always appropriate for every situation.
