作者： Amelia Henry Rice breeding Innovations department International Rice Research InstituteLos BanosLagunaPhilippines

Rice ratoon cropping,or the cultivation of tillers that have regrown from existing stem nodes of a harvested crop,is currently a hot topic in agriculture,and record-high ratoon crop yields have been achieved in China(Xu et al.,2021).Although rice ratoon cropping is most appropriate for certain agro-ecosystems with a suitable climate and cropping schedule,it is a promising strategy to simultaneously increase productivity while reducing inputs and *** ratoon cropping may thereby contribute to global food security and agro-ecosystem sustainability.
