Irrigation is done after adding manure and fertilisers, so that along with water, minerals and fertilisers are also absorbed by the soil.

Farmers store grains in jute bags or metallic bins. Large scale storage of grains is done in silos and granaries.

The crops grown in the winter season are called rabi crops. Their time period is generally from October to March.

Poor quality seeds are hollow and light. Good quality seeds are clean and healthy.

The process of loosening and turning of the soil is called tilling or ploughing. This is done by using a plough.

Modern methods of irrigation help us to use water economically. Some examples are: (i) Sprinkler system (ii) Drip system

2, 4–D is a weedicide.

The process of separation of grains from chaff is called threshing. Farmers with small holdings of land do it by winnowing.

Fertilisers are inorganic and are produced in factories.

Grains are dried before storage so that they do not get spoilt or attacked by microorganisms.
