Can you see the difference?SRI: Growth more vigorous, plants taller, darker green, longer panicles

SRI - right / conventional - left SRI – left/ conventional - right

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 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!

Page 14: 1601- SRI monitoring - Overview and preliminary results - Samar, Philippines

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!
