SRI management practice using 30 x 30cm spacing gave high yields and<br />
is cheaper than the currently recommended spacing <strong>of</strong> 20 x 20 cm, both in<br />
terms <strong>of</strong> seed requirement and labor cost for transplanting (Table 19).<br />

Transplanting at 20 x 20cm spacing with tiny seedlings is very tedious and<br />
time consuming; however, at 30 x 30 cm spacing, transplanting is much faster,<br />
and farmers prefer this spacing because yields are high and <strong>production</strong> cost<br />
significantly lower.<br />
