appropriateness score three categories of appropriateness
were developed viz., ‘very appropriate’ (score more
than 2.4), ‘somewhat appropriate’ (score 1.8 – 2.4) and
‘less appropriate’ (score less than 1.8).
The data relating to the extent of adoption of CRRI
rice varieties by the farmers revealed that majority (88%)
of farmers adopted rice variety Pooja followed by Sarala
(84%) and Durga (24%). The extent of adoption in terms
of area was highest for Pooja (45.97%) followed by
Sarala (40.21%) (Table 46).
The findings on appropriateness of CRRI rice varieties
revealed that rice variety Pooja was found to be
most appropriate with score 2.83 among the three
widely adopted lowland varieties as perceived by the
rice growers (Table 47).
Further analysis revealed that the rice variety Pooja
was found to be ‘very appropriate’ as perceived by highest

whereas, in case of rice variety Durga highest percentage
(60) of farmers perceived it as ‘somewhat appropriate’
for their land situation. The variety Pooja was found
to be most appropriate CRRI variety as perceived by the
farmers under study.
Prediction of requirement of quality seeds of
rice by the farmers of different ecosystems in
India
In the second phase, the study was conducted by
gathering data on indirect preferences of farmers of
Chhattisgarh and Jharkhand under different ecosystems
for rice seeds.
Chhattisgarh State
During dry season, the single most preferred variety
of rice by the farmers was MTU 1010. During wet
season 2011-12, the preferred upland varieties of rice
by the farmers of Chhattisgarh in decreasing order of
