Question: Drip Irrigation and Fertigation Technology for Rice Cultivation

Answer: As the demand for water for domestic, municipal, industrial and environmental
purposes rise in the future, less and less water would be available for irrigation.
Water availability for agriculture in India which is 83.3% of total water used
today, will shrink to 71.6% 2025 and to 64.6% in 2050 (Min. Agriculture, GOI).
We are almost exhausting all of the irrigation water to increase any more land under
irrigation.
Rice is the main grain that is in demand in India and South Asian countries.
A hectare of rice in conventional puddle cultivation uses 1300–1600 mm per
season according to the literature. But in practice, farmers use much more water
(up to 2000 mm) in many delta areas in India. In Asia, 17 million ha of irrigated
rice will face “physical water scarcity” and 22 million ha may have “economic
water scarcity” by 2025 (Tuong and Bouman, 2001). The highest share of this
inadequacy will occur in India, the largest rice producer of the region.
