In 2022WS, we tested 22 experimental and released hybrids developed by IRRI and other private companies to check for their productivity versus 2 inbred released varieties under puddled direct-seeded conditions. Direct seeding technology is a viable, alternative way of cultivating rice because it requires less water and when combined with mechanization, reduces labor and other expenses. IR139526H yielded the highest with 6.9 tons/ ha compared to the best inbred check, IRRI 201 which yielded 5.2 tons/ha, for a 33% yield advantage. We also found that Productivity Per Day (PPD) for IR139526H was 73 kg/day as compared to IRRI 201 which was 55kg/day. In 2023DS, we planted 25 hybrids and 2 inbred checks to measure their yield performance under the same wet direct-seeded culture. IR137395H was the top yielder with 9.6 tons/ha while the best inbred, IRRI 154, gave 7.5 tons/ha, for an advantage of 27% higher yield by the hybrid. PPD was 90kg/day for the hybrid and 69kg/day for the inbred. PPD is a simple yardstick to gauge a variety's value and usefulness especially when early maturity or a short growth duration is an ideal factor.
