unit 2010 2025 2050
Food grain demand million t 247 320 494
Net cultivated area m ha 143 144 145
Total cropped area m ha 193 204 232
Total irrigated crop area m ha 79 98 146
SCENARIO -PRODUCTION• Food production has to increase from 247 to 494 m MT
(AD 2050) to feed the ever increasing Population.
• Increase in cultivated area will not add much to this
requirement. (Possible increase only 2 m ha from the
present 143 m ha ).
• Converting rain-fed crops to irrigation cover (Partial or
Full) is the only way out (79 to 146 m ha).
5
SCENARIO- WATER • Gross Water Requirement increases to 1200 BMC from the
present 700 BMC.
• Available water remain at 1137 BMC
• Water deficit will force us to take extreme measures by 2030-2050.
• Before that happens conservation of water would help us survive better.
• Irrigation is the largest water user (+ 83%)
• Reducing water use in irrigation by increasing use efficiency will generate more water for irrigating more land area.
6
DRIP FERTIGATION TECHNOLOGY
• Drip Irrigation reduces water consumption• Drip-fertigation enhances for fertilizer use
efficiency.• Drip irrigation enhances yield.• Productivity increase with lesser and more
efficient resource use• This would be the Crux for future green
revolution and food security thru water and energy security.

RICE STATUS
• Cultivated area of Rice 43.79 m ha
• Irrigated area 25.1 m ha
(57%)
• Area of dry seeded rice 12.26 m ha
(28%)

WHY DRIP??
• DRIP Irrigation conserves water by 50-70 % besides
increasing productivity across crops.
• Drip –fertigation enhances productivity by 60-100%
• Lessons from several crops.

CHALLENGE
• As a country we should do things
OUT OF THE ORDINARY.
• One who dares wins
• We at Jain Irrigation have taken this
challenge.
• Field trials were conducted in
several states.

"... If a minimum ten per cent (especially rainfed area) of the total paddy area of 43.5 million hectares is brought under drip irrigation, then rice output can increase to 130 million tonnes by 2020,"
4.35 million ha under drip will result in irrigation water for an additional 4.8 m ha.

Jain Irrigation has been experimenting the concept of rice cultivation thru drip irrigation.
We work on our own: Experiments in Udumalpet, TN and Jalgaon, MS, farm
We work with farmers: In Rajasthan, AP, Chattisgarh, Tamil nadu, Maharashtra, Punjab.
We work with universities: Tamil nadu agriculture University
We work with International Institutions: IRRI,
