Part1 37 DAT| 79 Tillers/ Suwi/ Gipe LP Variety| Water Level Monitoring for less Nutrients Losses

WATER MANAGEMENT: Different crop establishment methods require different water management practices: After transplanting, water levels should be around 3 cm initially, and gradually increase to 5−10 cm (with increasing plant height) and remain there until the field is drained 7−10 days before harvest.  For direct wet seeded rice, field should be flooded only once the plants are large enough to withstand shallow flooding (3-4 leaf stage). Lowland rice is extremely sensitive to water shortage (below saturation) at the flowering stage. Drought at flowering results in yield loss from increased spikelet sterility, thus fewer grains.  Keep the water level in the fields at 5 cm at all times from heading to the end of flowering. In case of water scarcity, apply water-saving technologies such as Alternate Wetting and Drying (AWD) and consider changing planting method from puddled transplanting to non-puddled transplanting or dry-direct seeding.
