The study looked at how different planting methods and sowing dates affect the tillering characteristics and yield of hybrid rice. They found that primary tillers were the main contributors to yield, with mechanized direct-seeding having the highest yield from main stem. The tillering and panicle formation patterns varied between planting methods, with mechanized direct-seeding showing early and fast emergence of tillers. Artificial transplanting had a longer tillering time and more tillering leaf positions. The main stem and primary tillers in low and middle earbearing leaf positions had larger grain weight and yield. Overall, the study showed that planting method and sowing date can impact tillering and ultimately affect rice yield.
