Regional varietal trial (RVI') and Regional Farmers' Field Trial (RFFT) on potato were
conducted to find out the most suitable and high yielding varieties at the outreach research
(OR) site Hemja ( 1000 masl) and river-basins of westem hills during winter of 2001 and
2002. Seven genotypes were replicated three times in RVI' and si.t: times iiz RFFT.
Experiments were conducted in a RCB design with the plot size of 16.8m2 in RVI' and 21m2 in
RFFT. Spacing was maintained at 60cm x 25cnL Fertilizers were applied at the rate of 20 t/ha
FYM and /50:100:90 kg N: P20 5: K20/ha. Observations were recorded on yield and yield
contributing parameters. The pooled analysis of two-year RVI' data showed a significant
result on tuber yield per hectare. The maximum tuber yield (25.0 tlha) was recorded on
genotype 388764.26 LB and it was found at par. with NSI -17 (22.6 t/ha) and NSI-6 (22.5
t/ha). Where as the lowest yield ( 18.6 t/ha) was recorded in MS-42-3 and was found at a par
with NSI-3W (20.9), NS/-1 3 (21) and NS/-1 2 (20.2) t/ha, respectively. The weight and number
of under sized tubers and tubers/plam showed a significant and highly significallt effect.
Similarly, the pooled analysis of CFFT result showed a highly significant effect on tuber yield
due to genotypic effect. The highest yield (22.38 t/ha) was recorded on the NS/-17 and it was
found at a par with NS1-12, NSI-3W and NS/-6 where as the lowest yield (14.16 t/ha) was
recorded 011 local variety MS-42-3.
