Résumé : Plant structure components related to variation in yield between 25 cotton fields were investigated in the cotton growing area of Chaibadan District, Lop Buri Province during 1994 and 1995. Survival of P1 fruits (first flower bud appeared on a sympodium) of the first-ten fruiting nodes together with the change in Height to Node Ratio (HNR) were relevant criteria for analyzing yield differentiation. In a second step their relevance was validated with yield data from 75 plots surveyed in 1993. It showed that monitoring the production and survival of P] fruits, together with the changes in node number and height of the mainstem provided a meaningful appraisal of the origin and the cause of yield differentiation. From this type of monitoring, standards were generated with the aim of improving crop management through a better adjustment of inputs to actual plant structure.
