This study investigated the impact of transplanting density on the growth and yield characteristics of an extremely early-maturing rice variety that has a short vegetative growth period, as the limited growth period results in reduced tiller development and leads to a lower yield. The experiment was conducted in 2019 and 2020 at Chungcheongnam-do Agricultural Research and Extension Services in Republic of Korea, where various transplanting density treatments were tested using the Bbareumi rice variety with a vegetative growth period of less than 50 days. The results showed that the tiller number seedling−1 and spikelet number m−2 were influenced by the transplanting density and had a significant impact on the milled rice yield. Decreasing the tiller number seedling−1 by increasing the transplanting density led to an increase in the spikelet number m−2, which significantly improve the milled rice yield. Furthermore, the study identified the optimal transplanting density for maximizing yield as a transplanting distance of 30 × 12 cm, with 12 seedlings hill−1, which resulted in the highest milled rice yield of 5.64 ton/ha. These findings provide valuable insights for rice farmers and researchers regarding efforts to improve the cultivation practices of extremely early-maturing rice varieties.
