| Abstract: |
A field experiment was conducted at the Regional Agricultural Research Station, Parwanipur,
Bara, Nepal during summer seasons of 2011 and 2012 to assess the performance of hybrid
rice under varying levels of spacing and nitrogen under irrigated transplanted condition. Nine
treatment combinations of three spacings viz. 20 x 15, 20 x 20 and 20 x 25 em and three
nitrogen levels i.e. 80, 120 and 160 kg N ha· 1 were laid out in factorial Randomized Complete
Block Design, replicated thrice. The two years result revealed that spacing of 20 x 20 em and
application of 160 kg ha·1 nitrogen recorded significantly higher grain and straw yield. The
yield attributes viz. panicle length, spikelets panicle- 1
, 1000-grain weight, weight of grains
panicle-1 and filled grains panicle·' varied significantly ampng the treatments. Likewise,
application of 160 kg N ha·' recorded significantly higher plant height, dry matter and tiller
planf1
• Spacing of20 x 25 em recorded higher plant height which was at par with 20 x 20 em.
Biomass and tiller planf1 were significantly higher with spacing of20 x 25 em. Highest mean
grain yield of 5.10 t ha· 1 was found in spacing of20 x 20 em and 5.33 t ha·1 in 160 kg N ha·'
followed by 4.6 t ha-1 in spacing of20 x 25 em and 4.72 t ha- 1 in 120 kg N ha- 1
