The researchers studied the structure of rice panicles to see how it affects yield. They found that panicles from primary tillers contribute the most to high yields, followed by panicles from secondary tillers, the main panicle, and third tillers. To achieve a yield of 11.62 tons per hectare, specific conditions are needed: a planting density of 256,800 hills per hectare, 13.9 effective panicles per hill, 3.56 million effective panicles per hectare, 45.6 grams of grain weight per hill, 171.5 grains per main panicle, 130.5 filled grains per panicle from primary tiller, 88 grains per panicle from secondary tiller, and an average of 130 grains per panicle and 3.63 grams of grain weight per panicle.
