Abstract
This paper described the effects of local plant density on stubble lodging stability in the Direct Sowing on Moistened Paddy (DSMP) system. Plant density distribution and anti-lodging resistance were measured at the ripening stage. Plant density showed high values but small number of tillers per stubble at the site of lodging emergence. Voronoi diagram showed different from stubble concentration between lodging and non-lodging sites. Lodging resistance was low in the lodged site compared with the non-lodged ones. Plant stubble management needs localized control looking at every site of a couple of stubbles.
