Optimal transplanting date for double-cropping late rice boosts yields significantly!
Double cropping late rice seedlings on dry land beds with Shanyou 64 is best done with 1.333kg/hm2 of seeds. Early transplanting with different seed quantities doesn't affect yield. Delayed transplanting and older seedlings lead to lower spike effectiveness and reduced yield. Transplanting late significantly impacts yield, with July 28 being the critical date.
