  • 3. Perspective Plan for Self-Sufficiency
    • The State Government formulated in 1999-2000 a Perspective Plan for achieving self-sufficiency in foodgrains.
  • 4. REQUIREMENT OF FOODGRAINS BY 2010 Year Projected population (in lakhs) Foodgrains requirement (in lakhs tons) 2007-08 35.40 7.98 2008-09 35.92 8.09 2009-10 36.44 8.22
  • 5. STRATEGY FOR ENHANCEMENT OF CROP PRODUCTION
    • Supply of certified seeds to the farmers
    • Balanced use of fertilizers
    • Improvement in irrigation water use efficiency
    • Improvement of cultural practices (SRI , hybrid varieties)
  • 6. STRATEGY (contd..)
    • Adequate flow of credit
    • Gearing up of extension activities
    • Ensuring people’s participation through Panchayati Raj institutions
  • 7. AGRICULTURAL MECHANIZATION
    • Encouraging farmers for more use of agriculture implements
  • 8. SEEDS
    • SEED PLAN:
    • Thrust given for certified seed production through Seed Village concept.
    • SRR increased from 2.8% in 1999-00 to an optimum level of 33% in 2006-07.
    • Hybrid paddy seed production in farmers’ fields and Govt. farms.
  • 9. SEEDS ( CONTD ..)
    • Self-sufficient in certified seeds for HYV paddy, rape & mustard.
    • Surplus paddy seeds are marketed through NSC .
    • Pulse & Oilseed seed production in farmers’ fields through Seed Village concept is progressing.
  • 10. FERTILIZERS
    • Per-hectare use of NPK has been increased from 25 kg (1990-00) to 47 kg (2006-07).
  • 11. Why SRI ?
    • In spite of all efforts, however, productivity of rice hovers around 2.5 tons/ha. To achieve the goal of self-sufficiency, we need to increase the productivity to at least the level of 3 ton/ha.
    • To attain a breakthrough and increase in rice productivity significantly, SRI method are being tried in farmers’ fields.
  • 12. Research activities on SRI
    • Initiated in the year 1999-00 in boro season
    • Evaluated the adaptability under Tripura conditions for 5 seasons, until 2001-02, covering both kharif (aman) and rabi (boro).
    • Results were encouraging, prompting the Government to extend its support.
  • 13. Large-scale SRI Demonstration
    • The Department initiated a large-scale SRI demonstration programme in farmers’ field during 2005-06 with a target of 16,000 hectares, of which 14,876 hectares was achieved, covering more than 74,000 farmers of Tripura state.
    • The Department provided assistance to farmers @ Rs.4,500/ha for popularization of SRI.
  • 14. Demonstration and Training
    • Demonstration in farmers’ fields was taken up from the crop year 2002-03 Kharif
    • 2002-03 – 44 farmers @ 0.2 ha
    • 2003-04 – 88 farmers @ 0.2 ha
    • 2004-05 – 440 farmers @ 0.4 ha
    • 2005-06 – 880 farmers @ 0.4 ha
    • 2006-07 – > 74,000 farmers @ 0.2 ha
  • 15. Farmers’ training
    • Extensive training on SRI techniques was organized for farmers at village level and up to the district level throughout the state.
  • 16. Uprooting of young seedling without any trauma and transplanting them into the main field within 30 minutes Method-I
  • 17. Uprooting of young seedling without any trauma and transplanting them into the main field within 30 minutes (another method) Method-II
  • 18. Uprooting of young seedling without any trauma and transplanting them into the main field within 30 minutes (still another method) Method-III
  • 19. ONE SEEDLING PER HILL
  • 20.  
  • 21. SPACING MAINTAINED THROUGH LOW-COST DEVICE DEVELOPED BY FARMERS THEMSELVES
  • 22. WATER MANAGEMENT SRI success is possible under rainfed as well as irrigated conditions
  • 23. No standing water at the time of transplantation. In muddy soil, spacing of the drainage left as it is, and a drain is then created during the first weeding at 10-12 DAT
  • 24. Drainage channel in the main fields
  • 25. 12 days after irrigation / watering
  • 26. Drainage channel of 25 cm. width and 25 cm depth
  • 27. 60 DAT 65 tillers per hill / per plant (MTU 7029)
  • 28. 75 DAT 80 tillers per hill / per plant (MTU 7029) No standing water near the base of the plant, so no hindrance in the aeration
  • 29. WEED MANAGEMENT
    • Minimizes weed - crop competition
    • Maximizes aerobic condition in the field
  • 30.  
  • 31. Weeding schedule: 3 weedings at intervals of 10 -12 days, 1 st weeding should be 10-12 DAT
