An agronomic experiment to study the effect of diverse production systems on growth, yield and economics of Indian mustard varieties was conducted in the research farm of Division of Agronomy, ICAR–Indian Agricultural Research Institute (IARI), New Delhi, India during rabi season of 2021. The field experiment was laid-out in split-plot design in fixed layout with three replications. The field experiment comprised four main plot treatments (Production systems: Organic Management System (OMS), Integrated Crop Management (ICM), Conventional System (CS) and Conservation Agriculture (CA) and three sub-plot treatments (Mustard varieties-PM 26, PM 28 and PDZ 1). The results revealed that the plant height (cm), Dry matter accumulation (DMA), Leaf area index (LAI) of different varieties of Indian mustard under diversified production scenarios was significantly (p<0.05) influenced at 30, 60 90 days after sowing (DAS). There was almost 14% increase in seed yield was recorded under ICM compared to CS. Among the mustard varieties, PM 26 resulted in maximum seed yield (2206 kg/ha), closely followed by PM 28 (2123 kg/ha), while least seed yield was recorded under PDZ-1. Under OMS and ICM higher harvest index i.e., 0.23 and 0.24 respectively was observed which was higher than CS (0.22) and CA (0.20). The maximum net return (NR) was obtained under ICM (Rs 76583/ha) and among the varieties, PM 26 gave maximum NR of Rs 76060/ha. ICM and CA resulted in higher B:C ratio (2.87 and 2.97 respectively) compared to CS and OMS, while among the varieties maximum B:C ratio was from PM 26 (2.87) and least was from PDZ-1 (2.18).
