Field experiment was conducted to study the effect of planting material, cutting management and fertilizer levels on the growth, yield and quality of Bajra x Napier hybrid during 2009-10 to 2010-11. The quality parameters viz., DMY, CPY, CFY and silica were significantly higher with rooted slips planted at 90 cm x 60 cm, However, CPC, CFC, NDF, ADF, IVDMD, oxalic acid, ash, cellulose, hemi-cellulose and chlorophyll content were not influenced significantly due to different planting material used for propagation of Bajra x Napier hybrid. The quality parameters also differed significantly with various cutting management treatments. The quality parameters viz., DMY, CPY, CFY were significantly maximum with 60 days cutting interval, while the values of CPC, IVDMD, oxalic acid and ash were significantly higher at 45 days cutting interval. Whereas, CFC, NDF, ADF and ADL were found significantly higher at 75 days cutting interval indicating the inferior quality of green forage yield of Bajra x Napier hybrid. The significantly higher values of DMY, CPC, CPY, CFC, CFY, IVDMD, and silica content either at 45 days or 60 days cutting interval indicating desirable quality of GFY. Application of 150 % RDF registered significantly higher values of most of the forage quality parameters namely DMY, CPC, CFY, CFC, CFY, IVDMD, oxalic acid , ash, cellulose and hemi-cellulose content and chlorophyll content as compared to rest of the fertilizer levels. However, the maximum values of CFC, NDF, ADF, ADL and silica content was observed with 100 % RDF.
