5 FUTURE SHOCK ! Source: National Commission on Integrated water resources development, GOI PROJECTED FOODGRAIN DEMAND AND IRRIGATED CROP AREA unit Food grain demandmillion t Net cultivated aream ha Total cropped aream ha Total irrigated crop aream ha

6 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

7 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 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. Reducing water use in irrigation by increasing use efficiency will generate more water for irrigating more land area. 6

8 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. 7

9 RICE STATUS Cultivated area of Rice43.79 m ha Irrigated area25.1 m ha (57%) Area of dry seeded rice12.26 m ha (28%) 8

10 9 YIELD STAGNATION IN RICE

11 WHY DRIP?? DRIP Irrigation conserves water by % besides increasing productivity across crops. Drip –fertigation enhances productivity by % Lessons from several crops. 10

12 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. 11

13 12 PADDY WITH DRIP at UDUMALPET, TAMIL NADU JAIN R&D FARM Method Yield ( t/ac) Water use (lac liter/ac) Power Use (units/ac) Flood Drip Difference%

14 13 "... 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. FOOD AND WATER SECURITY THRU DRIP

15 DRIP IRRIGATED RICE Farmer’s Field, Narsapur, AP YIELD UNDER DRIP 3.2 t/ac Incremental yield hike in Drip1.2 t/ac (60%)

16 DRIP IRRIGATED RICE Farmer’s field in Kota, RAJASTHAN YIELD UNDER DRIP 8.5 t/ha (Variety Pusa 1121) Incremental yield due to Drip 1.5 t/ha (21%) YIELD UNDER DRIP 9.0 t/ha (Variety Pusa 2) Incremental yield due to drip 1.0 t/ha (12.5%)

17 16 RICE YIELD IN A TRIAL, JALGAON, MS (t/ac) Variety Flood Drip + Poly Mulch Drip + Husk Mulch SBH P P MAS Try (R) BPT Pusa Sugandha

18 17 YIELD UNDER DRIP FROM DIFFERENT STATES RICE PRODUCTION SCENARIO IN DIFFERENT STATES OF INDIA States Rice (x 000 ha) Average Yield (t/ha) Yield under drip- fertigation in trials (t/ha) Andhra Pradesh t/ha ( Variety US 311) Maharashtra t/ha (several varieites) Punjab t/ha (Arize 6129) Rajasthan t/ha (Pusa -2) Tamil Nadu t/ha (ADT -45) Uttar Pradesh t/ha (Arise 6129)

22 21  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, EFFORTS BY JAIN IRRIGATION
