About the RUFORUM 2010 Biennal Conference
"The 2010 RUFORUM Biennial Conference was the second 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 stakeholders 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. This record contains an extended abstract accepted under the theme of Natural Resource Management"
Phosphate sorption by andisols and ultisols, and its implication on phosphorus bioavailability in the wet tropics of Tanzania
Abstract:
Phosphorus (P) sorption and desorption behaviour of Andisols
of Siha - Kilimajaro and Ultisols of Magadu -Morogoro, Tanzania
was studied in pot experiments. This was to facilitate
development of P management strategies for enhanced maize
productivity as these areas have high P sorption capacities and
require high amounts of this nutrient for it to be available to
crops. Six P rates (0, 0.1, 0.2, 0.4, 0.8, and 1.0 mg P L-1) were
studied. There was a significant increase in maize dry matter
yield with addition of P at all rates. It is therefore recommended
that soils in the study areas be supplemented with P to improve
its availability to maize and thereby increase crop yield.
Le comportement d’absorption et de dégagement de Phosphore
(P) des Andisols de Siha - Kilimandjaro et des Ultisols de
Magadu-Morogoro, en Tanzanie a été étudié dans des
expériences en pot. Ce fut pour faciliter le développement de
stratégies de gestion du phosphore P pour la productivité du
maïs amélioré, car ces régions ont une grande capacité
d’absorption de phosphore P et nécessitent une grande quantité
de ce nutriment pour qu’il soit disponible pour les cultures. Six
taux de P (0, 0,1, 0,2, 0,4, 0,8 et 1,0 mg P L-1) ont été étudiés. Il
y a eu une augmentation significative du rendement en matière
sèche du maïs avec addition de P à tous les taux. Il est donc
recommandé que les sols dans les zones d’étude soient supplées
en phosphore P pour améliorer sa disponibilité pour le maïs et
d’augmenter ainsi le rendement des cultures.
