Correct option is A
1.
CRI (Crown Root Initiation) – 20–25 DAS
2.
Tillering/Jointing (optional)
3.
Booting
4.
Flowering/Heading
5.
Dough stage
Most critical:
CRI > Flowering > Dough.
Why other options are wrong
· (b) Wheat has no panicle stage (rice term).
· (c) Heading–maturity misses the critical
booting stage.
· (d) Two irrigations are highly insufficient for wheat.
