The study was conducted in N/Mecha district at Koga integrated research; technology transfer and community service center, kudmi site with objectives of studying the effect of sweet lupine (Vitabor) and hybrid Brachiaria Mulato II intercropping with on morphological characteristics, biomass yield, chemical composition, and silage quality of forage grown under irrigation condition. A randomized complete block design with four treatments and three replications was used for this experiment.(Treatment one;NPS fertilizer+ Brachiaria hybrid Mulato II grass intercropping with Sweet Lupin legume . Treatment two;Brachiaria hybrid Mulato II grass with Sweet Lupin legume without NPS fertilize. Treatment three;Brachiaria hybrid Mulato II grasswith NPS fertilizer.Treatment four;Brachiaria hybrid Mulato II grass sole ).Morphological characteristics such as plant height (PH), number of tillers per plant (NTPP),numbers of leaf per plant (NLPP), leaf length per plant (LLPP), number of roots per plant (NRPP), root length per plant (RLPP), leaf to stem ratio (LSR)and dry matter yield (DMY)) and chemical compositions of the Mulato II grass were recorded using the standard methods. The morphological characteristics of sweet lupine such as PH, number of the branch (NB), leaflet number (LN), number of nodes (NN), and nodule diameter (ND) were measured and counted using the standard methods. from each treatment were harvested, wilted, chopped, ensiled in a plastic bag, and silage was prepared after 21 days of anaerobic fermentation and displayed for sensory evaluation,chemical analysis and pH measurement. The sample was taken for analyses of chemical compositions of the forage such as dry matter content (DM); ash content, neutral detergent fiber content (NDF), acid detergent fiber content (ADF), acid detergent lignin content
