Abstract: Rice-wheat cropping system is the predominant and most profitable cropping system and emerges as the major cropping system in the Indo-gangetic plains, contributing more than 70 % of total cereal production in India. There are several constraints related to this system, like depletion of water resources, reduction in soil health, burning of residue and environmental pollution. Due to these constraints, the sustainability of soil health under rice-wheat system is great threat. Therefore, to enhance the soil physical properties for the sustainable soil health by alternative tillage practices a field experiment was conducted at N.E. Borlaug Crop Research Centre of Govind Ballabh Pant University of Agriculture & Technology, Pantnagar (Uttarakhand) during two consecutive years from 2015 to 2017. The experiment was conducted under strip plot design with three replications. Study revealed that bulk density was increased under zero till rice and wheat with Sesbania utilized as brown manure at 0-15 cm soil depth, while it was reversed at 15-30 cm soil depth during both the years. However, more soil moisture content was higher with zero till situation of both rice and wheat with retention of residues and Sesbania utilized as brown manure due to retention of residues that moderate the moisture fluctuations and thus reduce both evaporation and runoff. Among weed management practices, the higher values of soil bulk density and moisture content at different depths, after the harvest of rice and wheat crop were observed under weedy check, during both the years under rice-wheat system.
