Crop Production & Management Notes

• Water is important for proper growth and development of plants.
• The supply of water to crops at different intervals is called irrigation. The plant roots absorb water mineral and nutrients.
• To maintain the moisture of the soil for healthy crop growth, fields have to be watered regularly.
• The time and frequency of irrigation varies from crop to crop.

Sources of irrigation:

• The sources of irrigation are — wells, tube wells, ponds, lakes, rivers, dams and canals.

• The cutting of crop after it is mature is called harvesting.
• Harvesting is done manually by sickle or by a machine called harvester.
• In the harvested crop, the grain seeds need to be separated from the chaff. This process is called threshing.
• This is carried out with the help of a machine called ‘combine’.
• Farmers with small holdings of land do the separation of grain and chaff by winnowing.
