A field study was conducted to discover the effectiveness of a field water tube as a practical indicator for water management in lowland rice ( Oryza sativa L.). The field water tube was of 40 cm length and 15 cm in diameter so that the groundwater table could be easily visible.

The experiment was conducted in irrigated lowlands and followed alternate wetting and drying (AWD) practices by using field water tubes. The site had sandy clay soil. Grain yield was 6.0–7.2 t ha −1 with AWD irrigation and 7.5 t ha −1 with continuous submergence irrigation. Non‐significant ( P > 0.05) difference was registered in yield attributes and grain yield between continuous submergence of irrigation and I 5 (AWD irrigat...
