Conservation agriculture (CA) is being advocated as an alternative to conventional tillage based systems, as it not
only holds the potential to enhance soil biological properties, but could also sustain production in the long-run.
The impact of long-term tillage and nutrient management on soil biological properties, crops performance, yield
and returns were evaluated under maize-mustard rotation. Three tillage practices viz. zero tilled flatbed (ZTFB),
permanent bed (PNB) and conventional tillage (CT) along with three nutrient management practices; farmer’s
fertilizer practices (FFP), recommended dose of fertilization (RDF) and nutrient expert assisted: site-specific
nutrient management (NE®) were tested under the field conditions for six years (2013–2019). ZTFB produced
the highest average maize grain yield, which was statistically similar to PNB; however it was 28.4% greater than
CT. NE® and RDF recorded 27.4% and 24.8% higher yield over FFP, respectively. Similarly, ZTFB and PNB
produced 8.0% greater mustard seed yield than CT, while NE® and RDF had 23.5% and 22.3% greater seed yield
compared to FFP. Average of six years indicates, ZTFB and PNB produced 9.7% and 8.9% greater maize grain
equivalent yield (MGEY) than CT. Furthermore, NE® and RDF had similar MGEY, but 24.9% and 23% greater
than FFP. ZTFB and PNB gave the maximum economic benefits in comparison to CT plots. CT was 18.7% and
19.3% costlier than PNB and ZTFB, while RDF was more expensive than NE® and FFP. Plots under ZTFB and PNB
had 13.9% and 17.8% (0.0􀀀 0.15 m soil profile) and 14.6% and 12.5% (0.16􀀀 0.30 m soil profile) greater soil
organic carbon (SOC) than CT plots. These practices also had significant (p
