            i – immediately after sowing
            ii – crown root intiation : 15-20 das
            iii- active tillering stage : 35-40 das
            iv- flowering stage        : 50-55 das
            v- grain filling stage      : 70-75 das
            crown root initiation and flowering are the most critical stages. water stagnation should be voided at the time of germination.
