Groundwater is the primary source of water for agriculture in India, accounting for about 60% of the total water used for irrigation.

Drip irrigation is considered to be the most efficient irrigation method as it delivers water directly to the roots of the plants, minimizing water loss due to evaporation and runoff.

Fallowing is the practice of leaving fields fallow for a period of time, typically one or more growing seasons, to allow the soil to rest and restore its moisture and fertility.

Millet is a drought-tolerant crop that can thrive in dry conditions and requires minimal irrigation, making it a suitable choice for water-scarce regions.

Intercropping is the practice of planting crops in alternating rows with different water requirements, allowing for more efficient use of water and reducing the risk of crop failure.

Precision irrigation involves the use of sensors and automation to monitor soil moisture levels and adjust irrigation schedules accordingly, resulting in more efficient water use.

Mulching is the practice of covering the soil surface with organic matter, such as crop residues or compost, to reduce evaporation and improve soil moisture retention.

Contour farming involves planting crops along the contours of a sloped field to reduce soil erosion and water runoff, helping to conserve soil and water.

Conservation tillage involves using a minimum amount of tillage to prepare the soil for planting, helping to reduce soil erosion and conserve soil moisture.

Drip irrigation involves the use of perforated pipes or tubes buried underground to deliver water directly to plant roots, minimizing water loss due to evaporation and runoff.

Water conservation technologies involve the use of water-efficient appliances and fixtures to reduce water consumption in agriculture, such as low-flow irrigation systems and drip irrigation.

Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) is a government initiative in India that aims to promote water conservation and efficient water management in agriculture through various interventions such as micro-irrigation, rainwater harvesting, and watershed development.

Rainwater harvesting is the practice of storing excess rainwater for future use in agriculture, typically through the construction of storage structures such as tanks or reservoirs.

Sprinkler irrigation involves the use of large sprinklers to distribute water over a field, providing a more uniform distribution of water compared to flood irrigation.

Water-efficient crops are those that require less water for growth compared to traditional varieties, making them suitable for water-scarce regions.
