EVALUATING CARBON SEQUESTRATION, NUTRIENT USE EFFICIENCY, AND SOIL BIOLOGICAL PROPERTIES UNDER MAIZE-TULSI INTERCROPPING MODEL

Abstract

Improving carbon (C) sequestration has become a critical research priority for global agricultural sustainability. Carbon‐dynamics and their influences on microbial‐populations and crop‐productivity in maize‐tulsi intercropping system (MSI) remain unclear. Experiments were carried out at Renshou, Lezhi, and Yaan to investigate the carbon‐balance in terms of C‐sequestration across plants‐organs and its mechanistic influences on microbial‐populations and crop‐productivity in MSI. Tulsi was planted with maize in two different relay‐intercropping patterns (R11, 40:60 cm and R12, 50:50 cm) and the results compared against maize‐monoculture (MM) and tulsi‐monoculture(SM). Results showed that carbon‐accumulation in MSI was significantly (p < 0.05) higher than in sole‐cropping. Carbon accumulation was 5.96%, 23.9%, and 217.6% higher in MM, SM and R11 respectively, compared to the R12.
