Effect of different periods of irrigation on growth and yield of Cenchrus ciliaris at semi-arid zone of North Darfur State, Sudan

Buffel grass Cenchrus ciliaris L. (Poaceae) is recognized as one of Australia's most serious environmental weeds. This introduced grass has been associated with loss of native species and alteration of fire regimes. However, it is also highly valued as a pasture species for arid and semi-arid zones and its weed status is highly controversial. This study was conducted at the private farm, Southern part of Alfashir Airport, North Darfur State, Sudan. The objective was to evaluate the effect of different periods of irrigation (DPI) on growth and forage yield of Cenchrus ciliaris during years of 2018 and 2019. The experiment was laid-out in a randomized complete block design (RCBD) with four replicates, the plot size was 8x5 m. Data collected included plant density, plant ground cover, plant height and dry matter yield. DPI showed significant effect on plant density, plant ground cover, Plant height and dry matter yield. The study showed that irrigation every 7 days (Ir1) was suitable for buffel grass at semi-arid zone in Sudan. Quantitative studies are needed to determine its ecological effects.
