Intermediate yield trial (IYT) and coordinated varietal trial (CVT) of maize (terai set) were
conducted at Regional Agricultural Research Station (RARS), Doti during summer season of
the year 2012 and 2013. Twenty one genotypes of maize were included in IYT whereas
fourteen genotypes were included in CVT for both years. The experiments were laid out in
randomized complete block design with three replications. Amongst the tested entries
included in IYT during 2012, Rampur S03F08 recorded the highest grain yield (3609 kg/ha)
followed by Across 9531 (RE) (3474 kg/ha) and RPOP-1 (3223 kglha). Statistically, the
difference in days to flowering, plant height, ear height and grain yield due to genotypes was
found significant at 5% level. Similarly, same genotypes were planted in the year 2013 . Out
of the tested genotypes, Phraphuttabat S003 1 recorded the highest grain yield (5389 kg/ha)
followed by CEL-OHGY A x CELOH (5351 kg/ha) & Rampur S03F02 (53 12 kg/ha).
Statistically, the difference in days to maturity, plant height, ear height and grain yie ld among
the tested genotypes were found significant. Combined analysis over year indicated that the
genotypes Rampur S03F08 (4251 kg/ha), Across 9531 (RE) (4219 kg/ha), RPOP-1 (4099
kg/ha) and BLSBS07 -F 12 ( 4087 kg/ha) were identified as promising genotypes of maize for
river basin agro-environment of far western hills. Similarly, coordinated varietal trial of
maize was also conducted at RARS, Doti during 2012 and 20 13 . Fourteen genotypes of
maize including standard and local checks were included in the experiment of both years. The
experiment was planted in RCBD and it was replicated three times. Out of the tested
genotypes, RPOP-2 produced the highest grain yield (2645 kglha) followed by RPOP-1 (2407
kg/ha) and RPOP-3 (2268 kg/ha) during 2012. Statistically, the difference in days to
flowering, plant height and ear height due to genotypes was fow1d significant at I% level
whereas the difference in grain yield due to genotypes was found non-significant. The same
genotypes were planted in the year 2013 also. Out of the tested entries, RPOP-3 recorded the
highest grain yield (4880 kglha) followed by RPOP-4 (4304 kg/ha) and RPOP-2 (3885 kg/ha).
Statistically, the differences in all the traits included in the experiment due to genotypes were
found significant at 1% level. Combined analysis over year identified RPOP-3 (3465 kg/ha),
RPOP-2 (3415 kg/ha) and RPOP-4 (3286 kglha) as the promising genotypes for river basin
agro-environment of far western hills. Statistically, effect of treatment, year and interaction
between treatment and year was found significant at 1%.
