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
Can you see the difference?SRI: Growth more vigorous, plants taller, darker green, longer panicles
SRI - right / conventional - left SRI – left/ conventional - right
Santa Rosa (Balangiga)Mr. Evina‘s family: the pioneers of SRI in barangay Sta Rosa

Harvest -- Santa RosaComparison 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
Total 1 ha: 750 kg (0,75t)
Harvest -- Santa RosaSummary
SRI: 1,029 kg/ m2x
Conventional : 0, 75 kg /m2=
SRI increased the yield by 27,2 %
Harvest -- Santa RosaLeft = SRI: abundant, long roots, significantly higher number of tillers, long paniclesRight = conventional rice
Simple comparison of panicle volume per single hill: Left = conventionalRight = SRI
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

Iba SRI
Iba SRI x Conventional
Comparing current data ( 5 field observations)SRI average plant height: 89,85 cmSRI average number of tillers: 10,14
XConventional average plant height: 82,85 cmConventional 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)
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
Osmenia/ PananawanLesson learned:
Weeding makes a difference!
Osmenia/ PananawanEvidence of two extremes: left – SRI field completely damaged by weeds / right: well-managed SRI field,
example of good practiceFarmer‘s activity / proper care is crucial
for achieving good yield!

(data to be delivered)
New prospective SRI areas
For the next cropping season, harvest is planned in barangays:
• Sawa• New San Augustin• Buenavista
SawaMr. Paquito Mendova
The first beneficiary in barangay Sawa implementing SRI
New San AugustinCleaning the SRI area
More than 1 ha to be planted with SRI
BuenavistaNew SRI area
Fields preparation/ ready for planting
Thank you for your attention!
