Abstract
An experiment was conducted in Shambat (2016-2017) in the demonstration farm of the College of Agricultural Studies, Sudan University of Science and Technology to study the effect of variety and nitrogen fertilization on the quality performance of Rhodes grass. Two Rhodess grass varieties (Fine Cut and Reclaimer) and three nitrogen levels (60kgN/ha, 120kg N/ha and Control= 0.0kgN/ha) were investigated across seven cuts. The treatments were studied as factorial arrangement in Completely Randomized Design. Proximate analysis for Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF) and Crude Protein(CP) was carried out.
Highlights
Rhodes grass (Chloris gayana Kunth) has become one of the major forage crops throughout the tropical and sub-tropical World
The effects of nitrogen and cutting age were significant for Neutral Detergent Fiber (NDF) and Acid Detergent Fiber (ADF) whereas the effect of variety for both traits was not significant
The effect of nitrogen dose x cutting age was significant for NDF and ADF whereas the effect of dose x variety was significant only for ADF
Summary
Rhodes grass (Chloris gayana Kunth) has become one of the major forage crops throughout the tropical and sub-tropical World. It is a perennial C4 grass originated in Africa where it was first cultivated in 1985 (Loch et al, 2004; Ubei et al, 2001). It can be grazed, cut for hay or used as deferred feed, with moderate to high feed quality (Cook et al, 2005). Based on total seed imported up to 2017 the area cropped to Rhodes grass in Sudan could be estimated around 32000 ha
