Abstract: Conventional practices has for many years resulted in the deterioration of soil quality through depletion of soil organic matter and nutrients. Maize based system is being recommended as an alternate to rice-based systems to address the issues of resource degradation. Therefore, a two year field experiment was conducted in farmer’s participatory strategic research mode at Taraori, Karnal, India to evaluate the effect of conservation agriculture (CA) and green gram integration with precise nutrient management on soil quality and carbon sustainability index (CSI). Four treatment namely conventional tillage (CT), conventional tillage with green gram (CT+GG), permanent bed (PB) and permanent bed with green gram (PB+GG)] layered with three nutrient management strategies [farmer’s fertilizer practice (FFP), recommended dose of fertilizer (RDF) and site specific nutrient management (SSNM)]. The PB+GG recorded 29.4% higher water stable aggregates and lower BD. In PB+GG soil penetration resistance was reduced and infiltration was increased compared to CT. Soil organic carbon was significantly higher under PB+GG. Available N and P was 4 and 14 percent higher at 0-15 cm soil depth as compared to CT. SSNM recorded 1.72 and 3.50 % higher SOC as compared RDF and FFP, respectively at 0-15 cm soil depth. PB+GG recorded 18% higher CSI as compared to CT. SSNM increased CSI by 20 and 25% as compared to FFP during 2012-13 and 2013-14, respectively.
