10) What is arid region? :
The area where irrigation is must for agriculture is called arid region
11) What is semi-arid region? :
The area in which inferior crops can be grown without irrigation
12) What is crop period? :
The time period that elapses from the instant of its sowing to the instant of its harvesting is called crop period.
13) What is base period? :
The time between the first watering of a crop at the time of its sowing to its last watering before harvesting is called the base period
14) What is rotation period? :
The time interval between two such consecutive watering is called frequency irrigation.
15) Define duty of water? :
It is the relationship between the volume of water and the area of crops it matures is called duty of water.
16) Define delta of a crop? :
each crop requires a certain amount of water after a certain fixed interval of time, through its period of growth is called delta of a crop
17) What are the factors on which duty depends? :
1.type of crop
2.climate and seasons
3.useful rainfall
4.type of soil
5.efficiency of cultivation method
18) What are kharif crops? :
The kharif crops are rice,bajra,jawar,maize,cotton,tobacco, groundnut,etc.
19) What are rabi crops? :
Rabi crops are wheat,barley,gram,linseed,mustard,potatoes,etc
20) Define irrigation efficiency? :
It is the efficiency of water output to the water input,and is usually expressed as percentage.
