Question
The "Critical Stage" of irrigation in Wheat
is:Solution
CRI occurs about 21 days after sowing. Stress at this stage leads to a significant reduction in the number of tillers and overall yield.
A boat can cover 187 km in downstream in 11 hours and 180 km in upstream in 18 hours. Find the speed of boat in still water
The speed of a boat in still water is 20 km/hr. If the boat covers 90 km in upstream in 9 hours, then find the time taken by the boat to travel 150 km i...
