Abstract A field experiment was conducted during 1998–1999 to 2002–2003 at Sugarcane Research Station, Muzaffarnagar, Uttar Pradesh, India to find out the impact of various agro-technological manipulations on growth and yield of cane and sugar under multi-ratooning system. Combination of agro-techniques viz. dismantling of ridges, stubble shaving, subsoiling along stubble rows, ploughing in between stubble rows, trash mulching @ 3.5 tonnes ha−1, earthing up in July produced significantly higher values of growth attributes (number of shoots, leaf area index, dry-matter accumulation and net assimilation rate), number of millable canes and yield of cane and sugar as compared to rest of the agrotechniques assessed. This technique produced the highest cane yield of 81.48, 75.56 and 66.65 t ha−1, which was 31.68, 41.31 and 47.20% more than that obtained under farmers’ practice i.e., no cultural operation except trash burning during I, II and III ratoon, respectively. Application of any of the combination of agro-techniques, viz. dismantling of ridges, stubble shaving, sub-soiling, trash mulching or ploughing in between stubble rows proved advantageous in obtaining significantly higher yield of cane over farmers’ practice in multi-ratooning system.
