    abstract = {Rice cultivation in Asia including Nepal is
becoming most challenging due to excessive tillage and
unscientific use of resources like labor, fertilizers and
water. To address this problem and to observe
performance and profitability of rice over various SSNM
and crop establishment approaches, an experiment was
conducted on the silty loam soil with slightly acidic pH in
the research fields of CNRM, Puranchaur, Kaski. The
experiment was laid in Strip plot design consisting three
crop establishment methods (ZT-DSR, RT-DSR and TPR)
and four Site-Specific Nutrient Management (SSNM)
options (NE Model, LCC, CCM-200 and FFP) with three
replications in the fields where the initial crops were
mustard, potato and garlic, respectively. Khumal-4 variety
of rice, among the various SSNM options CCM-200
individually and its interaction with TPR, showed higher
LAI, above ground dry matter accumulation and growth
rate in many stages. The analysis of variance showed the
significantly highest grain per panicle (222.9) under TPR
but grain yield under ZT-DSR (4.11 t ha<sup>&#150;1</sup>) remained nonsignificant
with TPR (4.67 t ha<sup>&#150;1</sup>). CCM-200 performed
superior with significantly maximum effective tillers per
square meter (288.2), longest panicle (26.89 cm),
maximum number of grains per panicle (214), least
sterility (4.19%), comparatively higher grain (5.11 t ha<sup>&#150;1</sup>)
and straw yield (6.73 t ha<sup>&#150;1</sup>) and maximum economic
return with highest B:C ratio (2.24) which was
statistically at par with NE Model. Despite of the nonsignificant
interaction effect of crop establishment and
nutrient management on growth, yield and profitability of
rice, the combination of ZT-DSR and CCM-200 could be
more resource conserving and profitable.}
