Rice production in West Sumatra decreased due to the impact of climate change. One of the efforts to prevent water scarcity in the rice field is improving water management on the community scale. This study aimed to observe rice water management to prevent water scarcity. The research was conducted in the Tilatang Kamang subdistrict, Agam Regency, through field observation and interviews from November 2023 to April 2024. P3A Namuang Saiyo manages the water management for rice fields. Farmers used a rotational transplanting schedule to prevent water scarcity by cultivating rice 2-month intervals between the upstream, midstream, and downstream areas. The rice cultivated in 2023 shows yields in the areas of 3.48 t ha −1 , 3.88 t ha −1 , and 3.74 t ha −1 , respectively, using a conventional transplanting system (CU) of 37 x 37 cm. However, other conventional transplanting systems help farmers manage fertilizer with sizes 70 x 18 x 53 cm (M1) and 12 x 37 x 37 cm (M2). The results show that CU obtained a higher yield by 3.88 t ha −1 , followed by M2 (2.87 t ha −1 ) and M1 (2.23 t ha −1 ).
