1. In which of the following types of irrigation systems hydroelectric power can be generated?
a) Storage Irrigation
b) Perennial Irrigation
c) Flood Irrigation
d) Lift Irrigation
Explanation: Dams are constructed in this type of irrigation system, which leads to formation of reservoir on the upstream side of the dam. The hydroelectric power is generated when water is released through the dam for irrigation, or any other multipurpose, or when reservoir is full.
2. What type of irrigation system is based merely on gravitation?
a) Flow Irrigation
b) Direct Irrigation
c) Lift Irrigation
d) Storage Irrigation
Explanation: Flow irrigation is the type of irrigation in which supply of irrigation water is merely conveyed onto the land by the gravity flow or gravitation. In other words, water is supplied from higher grounds to lower grounds.
3. What type of irrigation method is also called as trickle irrigation?
a) Sprinkler Irrigation Method
b) Furrow Irrigation Method
c) Drip Irrigation Method
d) Check Flooding
Explanation: In this type of method, it involves laying a system of head, mains, sub-mains, laterals, and drip nozzles. From these nozzles, water oozes or trickles out at a small rate into the plant roots area. Hence the name trickle irrigation method
4. Drip irrigation method is a type of lift irrigation system.
a) True
b) False
Explanation: This method of irrigation contains a pump to lift water so as to maintain a desired pressure, for ensuring proper flow of water through the system.so, as it contains a mechanical means to supply water, it comes under lift irrigation system.
5. What is the quality of a good irrigation method from the following?
a) Soil Erosion
b) Drainage Troubles
c) Leached Fertilizers
d) Increased Yield
Explanation: Because good irrigation has uniform water distribution for both light irrigation and heavy irrigation. It also reduces conveyance and labor losses. It also facilitates mechanized farming. So, these advantages lead to increased yield.
6. In which type of irrigation method wasteful use of water happens?
a) Wild Flooding
b) Check Flooding
c) Furrow Method
d) Free Flooding
Explanation: This type of method is used in an inundation irrigation system in which water is forced to spread or flooded on a flat land, without much control or prior preparation. This leads to wasteful use of water.
7. Which type of irrigation method can be used for both flat lands and relatively steep lands?
a) Free Flooding
b) Basin Flooding
c) Furrow Method
d) Drip Irrigation Method
Explanation: Irrigation by this type of method is done, by dividing the entire land to be irrigated into a number strips called laterals. These laterals may be perpendicular to the sides of the field or perpendicular to the contour lines. So, as this method uses contour lines of field it is suitable for both flat lands and steep lands.
8. Which type of irrigation method uses supply ditch, borders, ridges
a) Border Flooding
b) Check Flooding
c) Basin Flooding
d) Drip Irrigation Method
Explanation: This type of method uses borders to divide the land into strips of with 10 to 20 meters, 100 to 400 meters in length each. Ridges are provided between borders so as to prevent overtopping during irrigation. Supply ditches run perpendicular to borders either on one side of the field to provide water for irrigation.
9. What kind of irrigation method uses artificial rain to irrigate the land?
a) Sprinkler Irrigation Method
b) Drip Irrigation Method
c) Furrow Method
d) Border Irrigation Method
Explanation: In this method, water is applied to the field through a network of pipes connected to sprinklers of different types, and through these sprinklers, water comes out as artificial rain and waters the crops in the field.
10. What type of irrigation method is considered as the most advantageous method?
a) Drip Irrigation Method
b) Sprinkler Irrigation Method
c) Furrow Irrigation Method
d) Border flooding
Explanation: This type of method can be used for any kind of crops, for all kinds of soils, and for widely different topographies and slopes. It can also be used in places of low or scarce availability of water, and also where water table is high. So, therefore it is the most advantageous method.
