The field experiment was carried out in twotehsils namely Salumber and Sarada of Udaipur district situated in Humid Southern Plain Zone of Rajasthan (IVb) on 36 farmers’ fields from kharif 2007 to rabi 2009–10. Application of complete recommended package of practices i.e. improved varieties seeds, seed treatment with Azotobacter, recommended spacing and fertilizer doses, irrigations at critical stages, plant protection measures and weed management, resulted in significantly higher maize-grain equivalent yield (10.5 t ha⁻¹), net returns ( 85.7 × 10³ ha⁻¹), benefit: cost ratio (4.09) and maximum production efficiency (44.9 kg ha⁻¹day⁻¹) of maize-wheat cropping system over rest of the treatments. Hence, farmers should adopt complete recommended package of practices in maize-wheat cropping system for realizing sustainable production. However, resource-poor and marginal farmers who cannot afford to apply the full package should adopt at least one most critical yield limiting factor.
