The main objective of present study was to determine the effect of different levels of nitrogen and plant spacings on yield of Mott grass (Pennisetum purpareum Schum) at different cuttings. Plant spacings (inter row and intra row spacings) are S1 = 45 x 45 cm, S2 = 60 x 60 cm and S3 = 75 x 75 cm and nitrogen levels included N0 = 0 (control), N1 = 100 kg, N2 = 200 kg, N3 = 300 kg and N4 = 400 kg ha-1. Production potential of Mott grass was determined on the basis of green fodder and dry matter yield. Application of N at different plant spacings increased both green fodder and Dry matter yield significantly over control in all the three cuttings. Crop fertilized at 300 kg N ha-1 produced the maximum green fodder yield 509 t ha-1 and Dry matter yield (97 t ha-1) of all the three cuttings at the spacing pattern of 45 x 45 cm.
