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. Can you see the difference?
SRI: Growth more vigorous, plants taller, darker green, longer panicles
SRI - right / conventional - left SRI – left/ conventional - right

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. 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. Harvest -- Santa Rosa
Summary
SRI: 1,029 kg/ m2
x
Conventional : 0, 75 kg /m2
=
SRI increased the yield by 27,2 %

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. 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. 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. Iba SRI

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. 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. Osmenia/ Pananawan
Lesson learned:
Weeding makes a difference!

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. Osmenia/ Pananawan
Harvest
(data to be delivered)

16. New prospective SRI areas
For the next cropping season,
harvest is planned in barangays:
• Sawa
• New San Augustin
• Buenavista

17. Sawa
Mr. Paquito Mendova
The first beneficiary in barangay Sawa implementing SRI

18. New San Augustin
Cleaning the SRI area
More than 1 ha to be planted with SRI

19. Buenavista
New SRI area
Fields preparation/ ready for planting
