Verification and refinement of the System of Rice Intensification (SRI): 1st year trial monitoring report of BRAC sub-project areas
We conducted SRI trial in two Upazilas of Noakhali district. The farmers practiced both SRI and conventional cultivation at a time to compare the results regarding production cost, yield and net return. Farmers applied less chemical fertilizers in SRI plots compared to conventional plots, which i...

We conducted SRI trial in two Upazilas of Noakhali district. The farmers practiced both SRI
and conventional cultivation at a time to compare the results regarding production cost, yield
and net return. Farmers applied less chemical fertilizers in SRI plots compared to conventional
plots, which is expected. They did not use pesticides but adopted IPM cultural method for both
practices indicating no attack of pests. Per hectare irrigation cost was more or less same for
both practices though it was supposed to be less for SRI method. Water supplier might have
counted frequency instead of water volume or there might have been system loss of water in
SRI plots. SRI farmers drastically saved seed cost (67%) compared to conventional farmers.
Famers weeded their conventional plot by hand while they used hand and also could use the
rotary weeder for SRI plot due to wider spacing. It permitted soil aeration, better root
development, more effective tiller and more panicle, which ultimately increase the yield in SRI
method. During the last Boro season (2002-03) SRI farmers got 43% more yield than
conventional one. Yield of straw was 39% higher in SRI compare to traditional method. Per
hectare production cost in SRI was 9% less than conventional method. So higher yield and
lower cost of production in SRI increased their net return to around 103% over that of
traditional practice. Benefit - cost ratio was 2.87 and 1.84 for SRl and conventional method
respectively. |
