Survival of budded seedlings in the field is important in the conservation of plant species, while girth size of rootstocks significantly influences percentage buddtake. Hence, the effects of six different media (TS, TS+GD, TS+CD, TS+OPS, TS+NPK and TS+Urea) on the development of Irvingia wombolu rootstock buddable within one year was investigated. Girth sizes of 1. wombolu root stocks grown for eight months in the five media showed variations, thus resulting in the emergence of two girth classes; buddable and difficult to bud girths. Rootstocks grown in TS+GD, TS+CD, TS+NPK and TS urea fertilizer media produced buddable girth range, 3.0-5.5cm, while TS, the control and TS+OPS media produced difficult to bud rootstock girths. Rootstocks grown in TS+GD medium produced rootstocks with the biggest girth, mean, 5.5 cm. Percentage budtake showed that rootstocks of big girths gave high percentage budtake (70-100%) as against rootstocks of thin girth (0.25%). Media percentage nitrogen contents strongly influenced rootstock girth increment. There is need for further studies on the survival of the eight months old budded seedlings in the field.
