Answer the following:

Suggest measures to conserve water in agriculture.

Water is one of the basic need for the production of food ie agriculture. Agricultural practices utilize 70% of the total ground water. It is a constant threat to the environment and as such, it is of utmost importance to conserve the water and use it as efficiently as is feasible.

In order to address the problem one can look into the following:

1. Irrigation system in use. Efficient irrigation involves two factors:

1. Available water must be used as and when required

2. Energy efficient irrigation system also contributes to the proper management of water

3. Knowledge regarding the root system of the plant helps in devising proper irrigation pattern. This will result in saturation of the root zone preventing surface run off and percolation of the root zone.

These factors if taken into account will result in the judicious use of water.
