3.Irregularity of Rainfall:
4.Multiplicity of Crops
5.Speciality of Crops
6.Nature of the Soil:
1. Uncertainty of Rainfall:
The total amount of rainfall in India varies not only from place to place, but also from time to time. In many parts of India, the rainfall is highly variable, which leads to greater incidence of famines and droughts. Increased irrigation facilities can reduce the problem of droughts and thus protect agricultural crops.
3. Irregularity of Rainfall:
The main source of rainfall in our country is the southwest monsoon winds in the summer season. These winds are highly irregular and often cause a long dry spell during the rainy season. This creates water scarcity and failure of crops. This problem can be solved through effective and dependable sources of irrigation.
4. Seasonality of Rainfall:
The main rainy season in India is between June and October. The duration decreases from about 6 months in Assam to about 2 months in northwest India. About 90 per cent of the total annual rainfall is received during second half of the summer season. Thus, irrigation is needed to supplement the rain water to raise crops in the dry season.
5. Multiplicity of Crops:
India has three cropping seasons Kharif, Rabi and Zaid. The Kharif crops are fully dependent on monsoon rains. The Rabi crops are raised on the soil moisture left after the harvest of Kharif crops or grown in areas with assured irrigation facilities. Zaid or summer crops are exclusively irrigated crops. The pressure of growing population forces the farmers to raise all the three crops.
6. Speciality of Crops:
Different crops require different quantities of water for growth. Millets barley, pulses, etc., need less water, while rice, sugar cane, wheat, potatoes, etc., need more water. The high yielding varieties using heavy doses of chemical fertilizers require more moisture, which can be given only through irrigation.
7. Commercialised Crops:
Many of the commercial crops need assured irrigation to improve the quality and quantity of their production. These crops generally need frequent watering which can only be managed through an efficient and reliable system of irrigation.
8. Nature of the Soil:
The need of irrigation is linked with the nature of the soil. The sandy loams need frequent watering due to less retentive capacity of moisture. On the other hand, the clayey soils have higher moisture holding capacity, and thus need less irrigation.
