Report is based on a survey of 120 farmers in two
districts, 60 using SRI and 60 non-users, randomly sampled.
1. Among non-users, 87.5% reported
having heard about SRI, mostly from other farmers, and 75% reported
that they intended to practice SRI in the future (Tables 1 and 2).
2. The main reason given by non-users
for unfavorable attitudes toward SRI was "requires more labor
and effort" (54%). Other reasons ranged from 12 to 2%. Physical
impediments ("water shortages, lack of suitable field")
were mentioned by only 9%. 69% of non-SRI farmers reported a favorable
opinion toward SRI in their community; only 9% unfavorable.
3. Advantages reported by SRI users
included: saving seed (100%), more tillers (98%), reduced demand
for herbicide (92%), less lodging (91%), improved seed quality (91%),
saving of water (90%), less disease and pest attack (88%), reduced
need for organic fertilizer (86%), reduced input cost (85%), more
yield (83%), less labor for harvesting (80%), and more milling output
(77%).
4. Disadvantages reported by SRI
users included: water management difficulties (77%), more effort
required (75%), requirement of well-drained soils (69%), required
additional work days (65%), organic matter not available (58%),
does not work on flooded fields (56%), transport of organic matter
is problematic (51%), more labor input required (50%), transplanting
is difficult (37%), skilled labor required for management (32%),
transplanting requires special skills (25%).
5. When analyzing factors influencing
SRI adoption with an elaborate statistical model, labor availability
and years of schooling were the main factors identified statistically.
The analysis showed no significant difference in SRI adoption between
rich and poor farmers, going against some previous reports on SRI.
6. In a parallel analysis of disadoption,
yield obtained had a statistically significant correlation, but
was not significant in substantive terms (only -.002). Poverty group
membership was negatively and significantly correlated with disadoption,
meaning that once they start using these new methods, the poor have
a higher probability of continuing with them than do rich farmers.
7. SRI farmers used less inorganic
fertilizer and more organic fertilization, as expected. The report
said that a considerable number of SRI farmers abandoned the use
of inorganic fertilizers altogether. SRI farmers who did not apply
any form of inorganic fertilizer had significantly better or comparable
yields to those SRI farmers who applied up to 150 kg of fertilizer
in both maha and yala seasons. Herbicide use among SRI farmers was
73% less, while mechanical weeding was only 33% more per hectare
and hand weeding only 7% more.
8. Irrigation reduction in terms
of hours of irrigation was only reduced by 21% for SRI farmers,
but given the higher yield, water productivity was raised by 90%.
9. SRI yields were 50% higher,
averaging 5.977 t/ha in 2003. This is lower than reported from many
other countries, and from some other locations in Sri Lanka, so
there is potential for SRI returns to be even higher in the future.
10. Costs of production per unit
of paddy output were not reported in the draft, but they were said
to be considerably lower with SRI. The report did say that the estimated
profit for SRI was almost double that of conventional practice in
both seasons.
11. The incidence of net losses
among SRI farmers was substantially lower than for conventional
farmers, irrespective of season (Section 5.3). Given farmers need
and desire to reduce risks, this could become an additional motivation
for SRI adoption.
