The study was conducted on raised bed (one pass) tillage system on the effect of fertilizer and irrigation levels at Wheat Research Centre, Nashipur, Dinajpur (25°38´ N, 88°41´ E and 38.20 m above mean sea level). Treatments were: T1; recommended fertilizer dose of N100 + P26.5 + K40 + S20 + Z4 + B1 with irrigation up to 75% field capacity, T2; recommended fertilizer dose with irrigation up to 100% field capacity, T3; recommended fertilizer dose with irrigation up to 125% field capacity, T4; 20% lower fertilizer dose than recommended dose with irrigation up to 75% field capacity, T5; 20% lower fertilizer dose than recommended with irrigation up to 100% field capacity, T6; 20% lower fertilizer dose than recommended with irrigation up to 125% field capacity. Irrigation water was applied at growth stages of 20, 55 and 75 days after sowing (DAS). Data on seasonal water use, yield and yield contributing characters of wheat were recorded during experimentations in raised bed cultivation systems. Results from this study indicated that the effect of fertilizer and irrigation level did not influence the grain yield and yield attributes of wheat under raised bed system. But, higher grain yield was found in the plots where recommended fertilizers were applied with irrigation up to 100% field capacity. Seasonal water was used by 211 – 231 mm and water use efficiency was found 1.53 – 1.78 kg m-3 by the treatments effect for one pass-tillage raised bed system. The short-term findings of this study raise the further crop physiological, fertilizer use efficiency and economics return study to confirm the results.
