Field experiments were conducted during rabi seasons of 1985–86 and 1986–87 on red sandy loam soil (Alfisol) to find out the effect of two irrigation schedules and three fertilizer levels on dry matter accumulation and growth attributes of potato cv. Kufri Jyotyi. Improvement in the growth parameters and dry matter accumulation was observed with the increase in frequency of irrigation and fertilizer levels. Under limited water availability, leaf area index (2.3), leaf area duration (48.8 days), dry matter accumulation (55.3 g/plant) and tuber yield (184 q/ha) were significantly higher in high frequency irrigation given in smaller quantity (20 mm) as compared to low frequency irrigation given in larger quantity (40 mm). Higher fertilizer level of 150: 150: 150 kg N, P2O5 and K2O per ha significantly increased the LAI (2.5), LAD (53.6 days), dry matter accumulation (52.6 g/plant) and tuber yields (175 q/ha) compared with other fertilizer levels.
