N2 - A field experiment was conducted at Crop Research Centre of the Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, during 1995-98, to study the effect of mulching (no mulch and trash mulch @ 6 tonnes/ha) and nitrogen doses (0, 75, 112.5, 150 and 187.5 kg N/ha) on growth and yield of sugarcane ratoon under foot-hill conditions of Uttaranchal. Trash mulching @ 6 tonnes/ha led to marginal improvement in shoot population, shoot height, shoot dry matter, cane length, cane girth and cane yield over no mulching. Individual cane weight exhibited significant increase with trash mulching (767 g) compared with no mulch (740 g) during 1996-97. Respective increase during 1997-98 was from 724 to 751 g. Improvement in yield attributes resulted in 3.2 and 5.8% increase in cane yield during the 2 seasons. All the growth parameters and yield attributes exhibited an increasing trend with increasing N level up to 187.5 kg/ha. Crop fertilized with 187.5 kg N/ha gave 4.5, 13.4, 21.0 and 43.1% more cane yield than that of 150, 112.5, 75 and 0 kg N/ha respectively.
