Seed yield in hybrid rice seed production plots depends, among other things, on the area under the female parent and the extent of seed set. Factors influencing seed set percentage on the female parent include row ratio, row direction, height of the pollen parent, weather conditions, particularly at the time of flowering such as wind velocity, pollen load, nature of the hybrid combination, and the adoption of practices that promote out-pollination such as proper application of GA3 and supplementary pollination.
