Abstract: Rice-wheat cropping system being predominant system in the Indo-gangetic plains is facing several constraints with the traditional practice of rice and wheat like depletion of soil health, burning of residue and environmental pollution, which affects the sustainability of soil quality besides productivity of rice-wheat system. Thus, to improve the soil health and quality sustainably two years field study was conducted at N.E. Borlaug Crop Research Centre of Govind Ballabh Pant University of Agriculture & Technology, Pantnagar (Uttarakhand) during 2015 to 2017 with 5 establishment methods and 3 weed management practices under strip plot design with three replications. Comparatively higher soil organic carbon was recorded in zero till than conventional transplanted rice. Treatment zero till rice-wheat cropping system with residue retention-Sesbania brown manuring resulted in higher values of SOC with stock at 0-15 cm soil depth. Residue retention, brown manuring and zero tillage led to enhancement in SOC with stock. While, weedy check recorded higher values of soil organic carbon content and stock at different depths, after the harvest of rice and wheat crop, among weed management practices under rice-wheat system.
