\textbf{Abstract}
\begin{abstract}
\normalsize{
In Sudan, forage production is very important for livestock production due to the facts that the Sudan has a huge number of animals. The main forage  grown under Sudan conditions is \textit{Sorghum bicolor} (var. Sudan grass),in This study  Two   experiments  were  carried  out  for   two seasons to measuring the  effect  of  organic  amendments  on  quality  of  (Sudan grass). Fodder quality is determined by characterisation of chemical composition and extent of digestibility.



All forages should be analysed for nutrient composition prior to feeding. An actual laboratory analysis is the only way to properly judge the quality or feeding value of forage. Forages should at least be analysed for dry matter (DM), crude protein (CP), fiber (acid detergent [ADF] or neutral detergent [NDF]).



in This study Generally, CP content is positively correlated with quality. In other words, high"=protein forages generally are high"=quality forages. The Neutral detergent fiber NDF value is the total cell wall, which is comprised of the acid detergent fiber (ADF) . ADF values are important in ration formulation because they reflect the amount of forage the animal can consume. As NDF percentages increase, dry matter intake will generally decrease. 



Also at two seasons organic amendment Chicken manure (CM), Farm Yard Manure( FYM) and CM+FYM  gave taller plants, higher number of green leaves, compared to the inorganic fertiliser (F) and control treatment. In general, plant height, increased with use of organic amendments and inorganic fertiliser at tow seasons. 



In general, all organic treatments and inorganic fertilisers had no significant effect on plant density.



Generally, at all organic amendments and inorganic fertiliser significantly increased fresh yield.



The data indicated that all fertilisers (organic and inorganic) were decreasing the NDF\,\% compared to control treatment. Generally all organic amendment gave lower (NDF) contents than inorganic fertilisers. 



The data also indicated that all organic amendment gave higher CP\% content compared to inorganic fertilisers and control. Generally all organic amendment (CM, FYM, CM+FYM) at first and second seasons were increased the CP\,\% content compared to inorganic fertilisers and control.
