The study looked at how spraying a chemical called uniconazole on rice seedlings affects their quality and yield when they are transplanted mechanically. They found that spraying uniconazole improved seedling quality, increased transplanting quantity, and boosted grain yield by up to 32%. Seedlings sprayed with uniconazole had shorter plants, lower MDA content, and better root health. The effects of uniconazole varied depending on the concentration used and the age of the seedlings. Overall, using uniconazole can help improve the growth and yield of rice plants in paddy fields.
