Water Management

Aerobic rice can be rainfed or irrigated. Irrigation can be applied through flash-flooding, furrow irrigation (or raised beds), or sprinklers.

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.

Irrigation:

IW/CPE ratio of 1.0 with 3 cm depth of water – total water requirement of 650 mm.

Surface drip fertigation:

Under aerobic rice conditions, schedule surface drip irrigation (with the lateral distance of 80 cm) at 125 % Open Pan Evaporation (PE) for clay soil / 150 % PE for sandy soil along with fertigation .

Sub-surface drip biogation:

Under aerobic rice conditions, schedule sub-surface drip fertigation (laterals concealed at 10 cm soil depth at a distance of 80 cm) scheduled at 125 % Open Pan Evaporation (PE) for clay soil / 150 % PE for sandy soil along with fertigation.
