Abstract: Irrigation is important in the agricultural production system to support the growth of plants, hence it can improve the crop. Rice as a staple food in Indonesia commonly requires more water than other plants. It is not only to support the plant growth but also to support soil cultivation and to reduce weed growth. This research aimed to analyze irrigation water requirements in the rice field according to the climate factor to determine the total amount of water and times. The observation was conducted in the rice field located at Kawangu village, Pandawai District, Sumba Timur Regency, East Nusa Tenggara Province, Indonesia. The rice (IF-16 variety) was planted in the field with different planting systems: (1) one seed per hole and (2) two-three seeds per hole. Further, the researchers also used two different spacing in planting: (1) 30×30 and (2) Jajar Legowo 2:1. The climate data such as wind speed, rainfall, temperature, humidity, and solar radiation were taken during the rice season by using Automatic Weather Station (AWS). The data was taken according to the growth of the rice season from May to August 2021. The clean water requirement (NFR) of the rice in the study site was calculated in accordance with evapotranspiration (ETc), water layer replacement (WLR), percolation (P), and effective rainfall (Re). The result showed that NFR was different during the growth of the rice season, which the maximum value was found on June and July (10.22 and 10.08 mm/day). The NFR value can be used as guidance for the stakeholders in the Sumba Timur irrigation system to increase the efficiency and effectiveness of the irrigation for the rice field.
