Abstract

Four experiments were conducted for two consecutive seasons (2009/2010 and 2010/2011) in a semi-arid Savannah zone, at the University of Zalingei perimeter, two kilometers east of Zalingei town Western Darfur State. The aim of the research was to assess the land equivalent ratio of two leguminous pastures species viz. Clitoria (Clitoria ternatea) and Siratro (Macroptilium atropurpureum) intercropping at various cultural practices and fencing under rained conditions. The influence of tillage (conventional and conservation tillage), weeding (mechanical weeds control) and enclosures versus open grazing system treatments was determined. The experimental design used was spilt-plot design with three replicates, in which mechanical weed control was assigned to the sub-plot and tillage systems (conventional and zero-tillage) to the main plots. Data were collected on forage yield (fresh and dry matter production) and land equivalent ratio. The results indicated that, cultural practices and enclosure significantly increased total forage yield (fresh and dry matter production) which was coupled with high land equivalent ratio (i.e. over 1.0)
