Visitors received an
Farmer experiences: Mr. Vallab Debnath
In local govt area, 40 ha planted with SRI
  •   Practices under SRI:
      Seed rate – 2 kg/ac (conv. 20-25 kg/ac)
      Compost - 3 t/ac, NPK – 40 kg/ha
      (conv. applic. 70 kg/ac)
      8-10 day, single seedlings, gap-filling
      Water management – AWD
  Yield – 30-35 mond/kani (3 t/ac)
Field observations :
Bagabasa Gram Panchayat area
•    Swarna Mashuri and Pooja varieties
•    Square planting, 22 – 25 cm
•    Tillers per plant 25- 35 (ave. 30)
•    Water stagnation by rain but draining
•    First hand weeding by rotary weeder
2. Mr. Chowdhary (Sonapur)
Aman rice – planted with SRI methods
Seed rate – 2 kg/ac (conv. 25 kg/ac)
Seedling – single (conv . 5-6/hill), 10 d old
seedlings (conv. 30 days)
NPK fertilizer – 65 kg/ac (conv. 175 kg/ac)
Three rotary weedings – 12, 24 and 36 DAT
(conv. 2 hand weedings); AWD irrigation
No lodging; reach maturity 5-7 days earlier,
but pest attack is more in SRI
Paddy yield expected from present aman crop:
• 40 mond/kani - 3.8 t/ac (9.5 t/ha)

• Labour problem especially for weeding
• Time-bound operations
3. Mr. Amirthalal Das, Indhiranagar
10 d old seedlings, single seedlings,
square planting, 25 x 25 cm spacing
Rice yield
40 panicles/hill, 38 mond/kani – 3.8 t/ac
(conv. yield 1.8 t/ac -- 9.5 vs. 4.5 t/ha)
Yield >doubled; cost reduced; 15 days
earlier maturity; low pest pressure; good
grain filling; low chaff (few unfilled grains);
maximum tillering; only labour is a problem
    After the field visit, 6 presentations were
                made by delegates
