Farmers‟ perception evaluation on SRI as shown in Table 4 that most <strong>of</strong> the respondents knew about SRI<br />

from NGO personnel and still learning about it in details. All participating farmers also reported that 100% <strong>of</strong><br />

their lands were brought under Boro rice cultivation using irrigation water from STW. Forty percent <strong>of</strong> the<br />

Boro rice area was cultivated by SRI method and the adopters <strong>of</strong> SRI have earned extra benefit <strong>of</strong> about Tk<br />

4000/bigha 12 over the conventional method (CM). All adopters opined that SRI method is really a good<br />

practice for rice cultivation which resulted in higher yield as well as higher return.<br />

Comparative scenario <strong>of</strong> seedbed management<br />

Table 5 showed comparative scenario <strong>of</strong> seedbed management for SRI and CM. <strong>The</strong> findings revealed that<br />

the land requirement for seed bed <strong>of</strong> SRI technique (1 decimal <strong>of</strong> seedbed for transplanting 33 decimal land<br />

area) is significantly less than that <strong>of</strong> conventional method (4 decimal <strong>of</strong> seedbed for transplanting 33 decimal<br />

land area). Quantity <strong>of</strong> seed required for raising seedlings <strong>of</strong> SRI method is only 2 kg/bigha whereas it was<br />

much higher (10-12 kg/bigha) for CM. Total labour requirement for seedbed management in SRI method was<br />

substantially less compared to that <strong>of</strong> CM. Water and fertilizer requirement was also less in SRI method<br />

compared to CM. <strong>The</strong> level <strong>of</strong> insect-pest infestation was very low in SRI plot compared to CM.<br />
