Enough water supply is vital for plant growth. There are two main ways that farmers get water to cultivate crops:

Rain-fed farming
Irrigation.

Rain-fed farming is simply natural supply of water to the soil rainfallwise. Rain-fed farming is continuously challenging and becoming unreliable due to climate change.

Farmers were particularly worse hit this year due to paucity of rainfalls and almost two months' droughts. A smart farmer thus needs to realize that farming is no longer business as usual.

Once rainfall is not sufficient, the plants need to survive on additional water via irrigation.

Selecting an appropriate irrigation system is a herculean labour. Irrigation styles are as varied as the people who use them. Different systems can be deployed to supply artificial water to the plants. Each system comes with its own merits and demerits.

However, the right selection depends on soil, water and climatic conditions as well as crop types, farmer's knowledge and preference, capital and operating costs, and existing farm infrastructure.

This post is mainly for the farmer who chooses to reap huge benefits from dry season farming and he/she has decided to irrigate and is in the process of making a decision on which type of irrigation system will best fit into his or her farm operation and setting.
