Abstract

121 words

A study to evaluate the effects of rooting substrate and planting techniques on the rooting of Vitellaria paradoxa stem cuttings is being conducted at Ngetta Zonal Agricultural Research and Development Institute (Lira district-Northern Uganda). Between October 2011 and April 2012, coppice cuttings of both soft and recent growth have been evaluated under three different substrates and survival rate assessed using two planting techniques (planting singly in pots and placement in mass of substrate). Cuttings rooted in vermiculite produced a significantly higher number of rooted cuttings than those rooted in other substrates. Although pine bark supported formation of new shoots considerably, no rooting was observed in cuttings rooted in this medium. The placement of cuttings in pots significantly enhanced their survival rate.
