UPSC Civil Services Model Paper 4

Unlike flooded rice, irrigation, when applied is not used to flood the soil but to just bring the soil water content in the root zone up to field capacity.
So, it actually reduces water consumption, and the field is not flooded or saturated. So, statements 1 and 2 are NOT correct.
Aerobic rice is a production system in which especially developed "aerobic rice" varieties are grown. So, statement 3 is also NOT correct.
