List of top Agronomy Questions on Irrigation Water Requirement Calculation

A sugarcane crop of 2 ha area was irrigated 5 times with 6 cm water in each irrigation. Work out the total quantity of water applied in cubic meter.
The crop coefficient (Kc) for major crops at harvest:
A. Maize
B. Sorghum
C. Soybean
D. Cotton
Match with the following Kc values:
I. 0.50 – 0.60
II. 0.55 – 0.60
III. 0.65 – 0.70
IV. 0.40 – 0.50
Choose the correct answer from the options given below:
Actual evapotranspiration equals maximum evaporation (ET0) when:
A. Soil moisture not constraint
B. Other factors not constraint
C. Both A and B
D. A but not B
Choose the correct answer from the options given below:
A wheat crop grown on two hectare area produced 10 ton grain and required 5 irrigations of 6 cm each, find out its field water use efficiency:
How much area can be irrigated with a flow rate of 30 liters per second for 10 hours a day when irrigation requirement of the 100 days duration crop is 50 cm?
The ratio of average depth of water stored in root zone soil depth during irrigation to the water diverted from the reservoir is known as:
The correct order of crops with respect to their water requirement is:
Water requirement satisfaction index (WRSI) can be computed using the information on seasonal actual evapotranspiration (AET) and seasonal crop water requirement.
