The experiment was conducted at the Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur, Bangladesh during November 2005 to April 2006 to study the seed production potentiality of BSMRAU developed open pollinated radish varieties (viz., BU Mula 1 and BU Mula 2) under two levels of root cutting (viz., one third and no cutup) and three levels of uprooting namely 30, 40 and 50 days after sowing (DAS). Results revealed that both root cutting and uprooting days significantly influenced most of the characters pertaining to seed yield per plant. Root cutting delayed the flowering, pod initiation, maturation of siliqua and reduced plant height, number of branches per plant, number of siliqua per plant, and number of seeds per siliqua. The yields were also impaired by root cutting. In general, the entire yield components and seed yield were highly affected with the one third root cutting. Various uprooting days also had influenced these characters. In case of treatment combination of no cut and 30 days of uprooting there was a significant difference between the varieties. The variety BU Mula 2 produced better seed yield per plot than BU Mula 1. Also in both the varieties the 1/3rd cut treatment with 30 or 50 days uprooting sequence showed unsatisfied number of seeds per siliqua in comparison to the no cut treatment except 40 days uprooting.
