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"
Comparative effects of Minjingu phosphate rock and triple super phosphate on residual P in an Ultisol
Abstract:
A glasshouse experiment was conducted at Sokoine University
of Agriculture to compare the effects of Minjingu Phosphate
Rock (MPR) and Triple Super Phosphate (TSP) on Residual
Phosphorus in an Ultisol. The soil was collected after seven
years since 480 kg/ha fertilizer application was stopped. MPR
and TSP fresh application increased significantly (P= 0.05) the
soil phosphorus, maize dry matter yield (DMY), P concentration
and uptake. Both residual P from MPR and TSP treated soil
were comparable in Bray I, maize DMY, and P uptake although
the values were lower than for fresh application. The values
were above the suggested critical concentration.
Une expérience de serre a été entreprise au sein de la faculté
d’agronomie de l’université Sokoine pour comparer les effets
du Phosphate Naturel de Minjingu (MPR) et du Phosphate
Super Triple (TSP) sur le phosphore résiduel dans un Ultisol.
Le sol a été rassemblé après sept ans puisque l’application
d’engrais de 480 kg/ha a été arrêtée. L’application fraîche de
MPR et de TSP a augmenté de manière significative (P= 0.05)
le phosphore du sol, le rendement en matière sèche de maïs
(DMY), la concentration en P et son absorption. Les phosphores
résiduels du sol traité avec MPR et TSP étaient comparables
dans le Bray I, le rendement DMY du mais et l’absorption du
phosphore P bien que les valeurs aient été plus inférieures que
pour l’application fraîche. Les valeurs étaient au-dessus de la
concentration critique suggérée.
