1601- SRI monitoring - Overview and preliminary results - Samar, Philippines

  1. 1. SRI monitoring an overview & preliminary results December 2, 2015 Barbora Chmelova
  2. 2. Santa Rosa (Balangiga) General information • 2 varieties observed: Red rice, Jasmine rice • Total area (2 fields): 340 sq meters (0,034 ha) • Slightly irrigated, well-drained • Organic fertilizer (vermicast) applied 2 times (@ land preparation + vegetative phase) • Date of sowing: July 9 • Date of transplanting: July 17 • Date of harvest: November 11
  3. 3. Can you see the difference? SRI: Growth more vigorous, plants taller, darker green, longer panicles SRI - right / conventional - left SRI – left/ conventional - right
  4. 4. Santa Rosa (Balangiga) Mr. Evina‘s family: the pioneers of SRI in barangay Sta Rosa From left side: SRI field in perfect condition/ Preparing the field identification signs / Four generations of farmers
  5. 5. Harvest -- Santa Rosa Comparison SRI x Conventional • Total area: SRI = 340 m2 (0,034 ha) Jasmine: 4 sacks=200 kg Red rice: 3 sacks= 150 kg Total: 350 kg (0,35 t) Total 1 ha: 1029 kg (1,029 t) ---------------------------------------------------- • Total area: Conventional field = 2000 m2 (2 ha) Filipino rice (local): 30 sacks = 1500 kg
  6. 6. Harvest -- Santa Rosa Summary SRI: 1,029 kg/ m2 x Conventional : 0, 75 kg /m2 = SRI increased the yield by 27,2 %
  7. 7. Harvest -- Santa Rosa Left = SRI: abundant, long roots, significantly higher number of tillers, long panicles Right = conventional rice Simple comparison of panicle volume per single hill: Left = conventional Right = SRI
  8. 8. San Miguel (Balangiga) • SRI field on left completely without any maintenance (no fertilizers, no weeding, almost no water) • Still, ‘some yield’ is expected • An interesting example, but definitely NOT recommendable
  9. 9. Iba SRI General information SRI field: Red Rice Total area: 17x30 Date of sowing: 30.8.2015 Date of transplanting: 10.9.2015 Organic fertilizer applied (vermicast) Rice-duck integration ---------------------------------------------------------------- Conventional field: Red Rice Total area: 22x25 Date of sowing: 30.8.2015 Date of transplanting: 23.9.2015
  10. 10. Iba SRI
  11. 11. Iba SRI x Conventional Comparing current data ( 5 field observations) SRI average plant height: 89,85 cm SRI average number of tillers: 10,14 X Conventional average plant height: 82,85 cm Conventional average number of tillers: 13,1 = SRI significantly higher plants, but fewer tillers (reason: high water level in SRI field that prevents tillering / the harvest data might be interesting)
  12. 12. Osmenia/ Pananawan • In total, 21 fields observed, 1 check • Total area: 4800 m2 (0,48 ha) • Red rice, Jasmine rice, Blonde rice • Fields in different stages: growth x harvest • Rice-duck integration • Monitoring and data processing in progress
  13. 13. Osmenia/ Pananawan Lesson learned: Weeding makes a difference!
  14. 14. Osmenia/ Pananawan Evidence of two extremes: left – SRI field completely damaged by weeds / right: well-managed SRI field, example of good practice Farmer‘s activity / proper care is crucial for achieving good yield!
  15. 15. Osmenia/ Pananawan Harvest (data to be delivered)
  16. 16. New prospective SRI areas For the next cropping season, harvest is planned in barangays: • Sawa • New San Augustin • Buenavista
  17. 17. Sawa Mr. Paquito Mendova The first beneficiary in barangay Sawa implementing SRI
  18. 18. New San Augustin Cleaning the SRI area More than 1 ha to be planted with SRI
  19. 19. Buenavista New SRI area Fields preparation/ ready for planting
  20. 20. Thank you for your attention!
