Introduction In the era of climate change, sugarcane used to face a problem associated with water shortage due erratic rainfall patterns and lowered tables. Improved use efficiency using innovative crop management strategy is needed for sustainable production. Trash mulching different irrigation regimes can effectively modify plant's hydrothermal micro-environment increasing cane yield productivity. Methods Keeping this in background, field experiment was conducted at Sugarcane Research Institute, RPCAU, Pusa, India, from 2016–17 2018–19 investigate effects trash on productivity, (WUE) soil properties planting systems. The comprised 12 treatments including four methods viz. conventional flat (CF; 75 cm row spacing) (6 t ha −1 ), CF (75 without paired trench (PT) (30: 120 PT ) three schedules consisted (IW); cumulative pan evaporation (CPE) ratio 0.60, 0.80, 1.00 laid out strip plot design replications. Results discussion (103.5 found significantly higher over method or mulching. Concerning IW/CPE ratio, it that 0.6 resulted 16.9, 13.3% water-use efficiency, 37.1, 40.7% productivity those under 0.8, 1.00, respectively. Furthermore, parameters like microbial biomass carbon (SMBC) dehydrogenase activity were increased by 12.5, 17.5 % as compared results suggest rows scheduling adoption practices effective profitability way also sustaining health.
