e0“The CA consistently enhanced canopy development, phasic biomass, and final yield versus CT and FP. Pooled grain yield was highest under zero-till and permanent beds (6118 kg ha -1 ), exceeding CT (5400 kg ha -1 ) and FP (5265 kg ha -1 ). The 125 kg N ha -1 produced yields comparable to 150 kg N ha -1 in CA, while additional biomass at 150 kg N ha -1 accrued largely as stover. Nitrogen uptake and efficiency were superior under CA (zero-till: 146 kg N ha -1 uptake), with NUEs peaking at 125 kg N ha -1 . CA enriched and stabilized mineral N in surface and near-surface layers, and improved soil water content across 0–30 cm. Net returns and benefit–cost ratios were highest under CA”

- Intervention effect Conservation agriculture improved maize canopy development, biomass and yield over conventional tillage and farmer practice.
- Intervention effect Zero-till and permanent beds had the highest pooled maize grain yield.
- Intervention effect In conservation agriculture, 125 kg N ha -1 gave yields comparable to 150 kg N ha -1.
- Intervention effect The 150 kg N ha -1 rate added biomass largely as stover.
- Intervention effect Conservation agriculture improved nitrogen uptake and nitrogen use efficiency.
- Intervention effect Conservation agriculture enriched and stabilized mineral nitrogen in upper soil layers and improved soil water content.
- Intervention effect Zero-till with 125 kg N ha -1 produced returns comparable to 150 kg N ha -1 with lower input cost.
- Observation Conservation agriculture nearly doubled topsoil soil organic carbon from the 2008 baseline.
