The present study investigated the effect of nitrogen management on wheatfodder cowpea crop sequence. Significantly higher wheat grain equivalent yield (9351 kg/ha) was recorded with the treatment combination of 75% RDN through chemical fertilizer + 25% RDN through vermicompost to wheat and 100% RDN to fodder cowpea (N2L3), which remained at par with the treatment combination of N3L2. At the same time, the highest net return (₹134939/ha) and benefit-cost ratio (BCR) (2.86) of wheat-fodder cowpea crop sequence were secured with the application of a recommended dose of fertilizer (RDF) (120- 60-00, NPK kg/ha + 25 kg/ha ZnSO4) to wheat and 100% of RDN to fodder cowpea (N1L3), which remained at par with the treatment combination of 75% RDN through chemical fertilizer + 25% RDN through FYM to wheat and 100% of RDN to fodder cowpea (N3L2).
