Observations from Field Trip: SRI Practices and Farmer Experiences in West Bengal

On October 5, 2007, a field trip led by Dr. L.G. Giri Rao included 50 delegates visiting three villages in West Bengal to observe System of Rice Intensification (SRI) practices. Farmers shared insights on improved yields using SRI methods, contrasting traditional techniques. Key findings included reduced seed rates, effective water management, and the use of rotary weeders, leading to enhanced productivity. Despite challenges like labor shortages, farmers reported yields up to 3.8 t/ac. The trip emphasized the practical advantages of SRI over conventional rice cultivation.

  3. Visitors received an overwhelming reception

  4. 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)

  5. 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

  6. 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

  7. Paddy yield expected from present aman crop: • 40 mond/kani - 3.8 t/ac (9.5 t/ha) • Constraints: • Labour problem especially for weeding • Time-bound operations

  8. 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
