Abstract

Nitrogen and potassium were applied with and withoult phosphorus to rubber seedlings at various rates and intervals prior to and after root stock pruning in an attempt to observe budding uniformity and stunting. The use of fertilizers pos-grafting was effective in promoting seedling growth and vigor. Uniformity, vigor and precocity of first whorl was related to fertilizing stocks 15 days prior to pruning, but the better at the 2nd whorld stage was obtained in stocks receiving NPK 30 days after pruning.
