Effectiveness of seed inoculation with Azotobacter for improving potato yield was assessed in pot and field experiments under optimum fertilizer application (NPK: 250-150-150 and 200-100-100 kg ha'. respectively). The data obtained from pot experiment revealed that inoculation significantly increased the tuber yield (up to 45.3 %), straw yield (UP to 61. 9 %) and the number of tubers plant ; (up to 82.4 %) compared with control (fertilizer appl ication alone). Similarly, inoculation was also _/'~ effective in enhancing the tuber yield (up to 32.3'1<1),straw yield (up to 15.9%) and the number of tubers plant' (up to 50.0%) compared wil1J controt, under ficJd cotuiuions.
