Verification and refinement of the System of Rice Intensification (SRI): 1st year trial monitoring report of BRAC sub-project areas
Year: 2003
Type: report
Abstract: We conducted SRI trial in two Upazilas of Noakhali district. The farmers practiced both SRI \nand conventional cultivation at a time to compare the results regarding production cost, yield \nand net return. Farmers applied less chemical fertilizers in SRI plots compared to conventional \nplots, which is expected. They did not use pesticides but adopted IPM cultural method for both \npractices indicating no attack of pests. Per hectare irrigation cost was more or less same for \nboth practices though it was supposed to be less for SRI method. Water supplier might have \ncounted frequency instead of water volume or there might have been system loss of water in \nSRI plots. SRI farmers drastically saved seed cost (67%) compared to conventional farmers. \nFamers weeded their conventional plot by hand while they used hand and also could use the \nrotary weeder for SRI plot due to wider spacing. It permitted soil aeration, better root \ndevelopment, more effective tiller and more panicle, which ultimately increase the yield in SRI \nmethod. During the last Boro season (2002-03) SRI farmers got 43% more yield than \nconventional one. Yield of straw was 39% higher in SRI compare to traditional method. Per \nhectare production cost in SRI was 9% less than conventional method. So higher yield and \nlower cost of production in SRI increased their net return to around 103% over that of \ntraditional practice. Benefit - cost ratio was 2.87 and 1.84 for SRl and conventional method \nrespectively.
