Description:	Abstract: The objectives of this study were to characterize how the water regime and the furrow and ridge environments affect the plant development stages (PDS) and how these stages relate to estimates of the App PlanejArroz. In the cropping season 1 – CS 1 (2021/2022), the PDS were obtained in three water regimes (water regime 1 – WR1; water regime 2 – WR2; water regime 3 – WR3). In the cropping season 2 – CS 2 (2022/2023), the water regime 4 - WR4 was included. The PDS were obtained through readings, twice a week, on the plants marked in the ridge and in the furrow. The results indicated that the number of days from emergence (ND) to reach the PDS was influenced by the water regime (WR), especially for stages R1 (panicle differentiation), R2 (booting) and R4 (anthesis), which showed differences between WR1 and WR3, respectively, of 7 , 6.3 and 7.9 days in the CS 1 and 4, 3.9 and 4.4 days in the CS 2. The results allow us to conclude that the irrigated rice PDS suffer delays in the furrow-ridge system and that the App PlanejArroz can be used to plan management practices in this system as long as corrections are made regarding the delay in the PDS.
