A field experiment was carried out during 2015–16 and 2016–17 on clay-loam soil of Rahuri, Maharashtra, to study the effect of drip fertigation as per soil test crop response (STCR) equation on system productivity and economics of maize (Zea mays L.)–onion (Allium cepa L.) cropping sequence. The experiment was laid in a split-plot design with 3 replications. The treatment consisted of 4 main plot treatments of fertigation levels based on STCR equation for 10 t/ha yield target [(100%, 75%, 50% of STCR and general recommended dose fertilizers) GRDF] for the rainy season (kharif) maize (grain) and same set of treatments based on STCR equation for 0.5 t/ha yield target (100%, 75%, 50% of STCR and GRDF) was applied for winter (rabi) onion (seed) as subplot treatments. Fertigation of N and K as per 100%, of STCR equation for 10 t/ha yield target with FYM to kharif maize followed by fertigation of N and K as per 100%, of STCR equation for 0.5 t/ha yield target with FYM in 4 equal splits at 15 days interval up to 60 DAS to rabi onion recorded significantly maximum maize grain yield (9.84 t/ha) during the rainy season and onion seed yield (0.54 t/ha) during rabi season. The system productivity (57.50 t/ha), production efficiency (190.96 kg/ha/day) and net monetary returns (541.82 × 103 `/ha) were also higher under fertigation of N and K as per 100% of STCR equation to kharif maize, followed by fertigation of N and K as per 100% of STCR equation in 4 equal splits at 15 days interval up to 60 DAS to rabi onion.
