Increasing carbon dioxide (CO2) content in the atmosphere is the prime cause of global warming. Capturing this CO2 by agro-forestry systems through photosynthetic activity could be one of the ways to reduce its concentration in the atmosphere. Therefore, an attempt was undertaken to fix the atmospheric CO2 employing the mulberry plant as the sink considering its carbon sequestration potential. The experiment was conducted in a red sandy loam soil following conventional practices of mulberry cultivation along with and without reduced tillage and mulching and two levels of irrigation (furrow and drip). The experiment was laid out in split plot design with four different management practices each replicated six times. Initial soil samples before the imposition of treatments and final after harvesting of last crops of third year were collected for analysis of different soil properties and available nutrient status. Results showed that conventional practices with reduced tillage and mulching and drip irrigation improved the soil properties in terms of reducing bulk density, increasing water holding capacity and increase available nutrient status. The carbon sequestration potential (CSP) of mulberry was also found to be higher in the former ( t ha-1 year-1 ) compared to other management practices. The rate of carbon sequestration (Mg ha-1 yr-1 ) in soils followed the order of reduced tillage and mulching with drip irrigation ()> reduced tillage and mulching with furrow irrigation () > conventional practice with drip irrigation () > conventional practice with furrow irrigation. | Assessment of carbon sequestration potential of mulberry vis-à-vis soils under different cultivation practices
