A biennial field trial was conducted on inceptisol of Pothwar, Pakistan to evaluate potential of five fertility treatments: no fertilizer; inoculation + Phosphorus and Potash (PK); Nitrogen, Phosphorus and Potash (NPK); poultry manure (PM) and half poultry manure + half PK + inoculation and to find out most promising combination maize-wheat; maize + black gram-wheat; maize + mungbean-wheat; black gramwheat and mungbean-wheat under diverse fertility sources. Results of the study revealed an increase of 12 % and 11% in grain yield of wheat after black gram and mungbean, respectively compared to wheat grown after maize. Black gram-wheat sequence gave 19 % higher water use efficiency compared to maize-wheat system. The yield of wheat increased by 20 % in plots previously treated with poultry manure @ 15 t ha-1 over no fertilizer. Plots amended with poultry manure in summer season registered 13 % higher water use efficiency of wheat over no fertilizer. Hence, legume-cereal (black gram-wheat) cropping sequence with poultry manure proved to be more productive and sustainable than cereal-cereal (maize-wheat) rotation.
