The effect of different root pruning lengths on the number of new root developed and length of tap root extension were determined. The overall response of root growth (RG) as exhibited by the number of new roots and length of tap root extension was found to be significantly affected (P= 0.05) by different pruning lengths. A positive response was observed: RG increased with root pruning (that is treatments with root pruning produces more new roots and developed more tap root length extension compared to those of control treatment with no root pruning. The result of the study shows that root pruning before transplanting had positive impact on the seedlings in term of producing new roots and extension of tap roots.

Key words: Root growth (RG), root pruning, new roots, root length extension.
