The experiment has been initiated at Wheat Research Centre, Nashipur, Dinajpur with wheat-mungbean-T. aman cropping pattern under old Himalayas piedmont plain in 2010-11. The soil was sandy loam in texture and soil was strongly acidic of the experimental site. The experiment was laid-out in a randomized complete block design with 3 replications and the lay-out kept undisturbed for the experimentation. There were 9 treatments of inorganic and bio-slurry in combination of inorganic fertilizers. The treatments for wheat were: T1 (Control), T2 ( 100% recommended chemical fertilizer), T3 (75% recommended chemical fertilizer), T4 (75% of RCF + 5.0 t ha-1 bio-slurry), T5 (75% of RCF + 7.5 t ha-1 bio-slurry), T6 (75% of RCF + 10.0 t ha-1 bio-slurry), T7 (75% of RCF + 5.0 t ha-1 bio-slurry in rice), T8 (75% of RCF + 7.5 t ha-1 bio-slurry in rice ) and T9 (75% of RCF + 10.0 t ha-1 bio-slurry in rice) . In case of rice, the treatments were: T1 (Control), T2 (100% recommended chemical fertilizer), T3 (75% recommended chemical fertilizer), T4 (75% of RCF + 5.0 t ha-1 bio-slurry in wheat), T5 (75% of RCF + 7.5 t ha-1 bio-slurry in wheat), T6 (75% of RCF + 10.0 t ha-1 bio-slurry in wheat), T7 (75% of RCF + 5.0 t ha-1 bio-slurry), T8 (75% of RCF + 7.5 t ha-1 bio-slurry) and T9 (75% of RCF + 10 t ha-1 bio-slurry). RCF means recommended chemical fertilizer. For rice, bio-slurry was excluded to T4, T5 and T6 to observe the residual effects in rice of different rates of bio-slurry. Again, the bio-slurry was included in the treatments T7, T8 and T9 to observe the direct effect of bio-slurry in rice and residual to wheat. The treatments T7, T8 and T9 for wheat and mungbean and T4, T5 and T6 for rice. In case of mungbean, only 20 kg N was received all treatments and kept in variation for mungbean same which were created in wheat and rice. The 100% chemical fertilizers for wheat was 100 kg N, 27 kg P, 50 kg K, 20 kg S and 1 kg B ha-1 and 70 kg N, 10 kg P, 40 kg K, and 10 kg S and 2 kg Zn ha-1 for rice. The source of N, P, K, S, B and Zn were urea, TSP, MoP, gypsum, boric acid and zinc sulphate respectively. Bio-slurry was spread to the plots and incorporated with soils before 7 days of crop planting for both wheat and rice. The fertilizer application and other management practices have been done following the recommendation for each crop to ensure normal growth. The variety, Prodip for wheat, BARI Mung 6 for mungbean and BRRI Dhan 39 for rice were used. Yield and yield contributing parameters were collected and analyzed in computer following MSTAT-C. Soils were collected initially from the experimental site and after each wheat and rice harvest from the individual plot and measured the soil pH in laboratory.
