In SRI, a single seedling is transplanted
per hill at a wider spacing and the hills are
also spaced more widely than usual, thus
reducing the density of seedlings needed
for planting ( from about 200per sq.m to
16/sq.m ) Thus only 5-7.5 kg seeds/ha are
required, instead of about 50 kg/ha in the
traditional method of rice cultivation. This
is more important in case of hybrid rice
where seed cost is very high. And the
farmers have to purchase seed every
year
