Abstract:
A study was conducted to establish the contribution of Eragrostis
superba, Enteropogon macrostachyus and Cenchrus ciliaris in
improving soil hydrological properties in semi-arid Kenya.
Kamphorst rainfall simulator was used on bare ground and at
different grass stubble heights. The experiment was set up under
sprinkler irrigation system. Sediment production as a function of
runoff and infiltration capacity was significantly different (p<0.05)
at different stubble heights. Cenchrus ciliaris had the greatest
influence on improving soil hydrological properties followed by
Enteropogon macrostachyus and Eragrostis superba respectively.
An increase in grass height increased infiltration capacity, reduced
runoff and sediment production.
Une étude a été menée pour déterminer la contribution des
Eragrostis superba, Enteropogon macrostachyus et Cenchrus
ciliaris dans l’amélioration des propriétés hydrologiques des sols
dans les zones semi-arides du Kenya. Le simulateur de pluie
Kamphorst a été utilisé sur le sol nu et à différentes hauteurs
d’herbe chaume. L’expérience a été réalisée sous le système
d’irrigation par aspersion. La production des sédiments comme
une fonction de ruissellement et de capacité d’infiltration a été
significativement différente (p <0,05) à différentes hauteurs de
chaume. Cenchrus ciliaris avait la plus grande influence sur
l’amélioration des propriétés hydrologiques du sol, suivi par
Enteropogon macrostachyus et Eragrostis superba, respectivement.
Une augmentation de la hauteur de l’herbe a augmenté la capacité
d’infiltration mais a réduit le ruissellement et la production de
sédiments.

Notes:
"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 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. This record contains an extended abstract accepted under the theme soil science and water management".
