Vegetative Propagation of Vitellaria Paradoxa by Stem Cuttings: Effects of Rooting Substrate and Planting Technique

Abstract: 
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.
Une étude visant à évaluer les effets du substrat d’enracinement et des techniques de plantage sur l’enracinement des boutures de Vitellaria paradoxa est menée à l’Institut Zonal de Développement et de Recherche Agronomique de Ngetta (dans le District de Lira- au Nord de l’Ouganda). Entre Octobre 2011 et Avril 2012, les boutures en taillis de la croissance à la fois tendre et récente ont été évaluées dans trois substrats différents et le taux de survie évaluée à l’aide de deux techniques de plantage (le plantage séparément dans des pots et le placement dans la masse du substrat). Les boutures enracinées dans la vermiculite ont produit un nombre significativement plus élevé de boutures enracinées que celles fixées dans d’autres substrats. Bien que l’écorce de pin ait supporté considérablement la formation de nouvelles pousses, aucun enracinement n’a été observé dans les boutures enracinées dans ce milieu. Leplacement des boutures dans des pots a considérablement amélioré leur taux de survie.

The 2012 RUFORUM Biennial Conference is the third in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. The third Biennial Conference was attended by 657 participants.This record contains an extended abstract accepted under the theme of Crop Improvement
