Yield Performance of Rice Hybrids Bred for Transplanted Condition under Puddled Direct Seeding

Abstract

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.
