| Abstract: |
In order to fmd out the appropriate time of planting to escape sunflower from Alternaria
blight (Alternaria helianthl) and head rot (Rhizopus sp.), Modem dwarf, SH-3322 & Hybrid
Indam varities of the crop were sown in two consecutive seasons on Feb. 7, 17 & 27 during
2011 and on 8, 17 & 27 during 2012 spring. In winter season of20 II the crop was sown on
Oct. 10, 20 & 30 in split plot design. Each variety and dates replicated thrice with a plot
size 9 m2 at NORP. Severity of Alternaria blight found higher in spring season compared to
winter season while head rot was found in moderate form in winter season. Modem dwarf
planted in second week of February produced the highest yield (651, 460 & 556) kglha with
highly significant treatment difference in the F.Y. 2010/11, 2011112 & in combination
respectively. whereas Hybrid indam yielded 1587 kg!ha followed by Modem dwarf {1336
kg/ha) in second week of October with highly significant difference among the treatments.
Therefore, planting f Modem dwarf in second week of February & October and Hybrid
indam in second week of October could be recommended for the cultivation under farmers
field condition. |
