Abstract
A study on susceptibility of promising sugarcane varieties to stalk borer, Chilo auricilius Dudgeon with different levels of nitrogen was conducted at PAU, Regional Research Station Gurdaspur during the year 2010–11 and 2011–12. The pooled mean of both the years showed that sugarcane variety CoJ 89 significantly had less (24.53%) incidence of stalk as compared to other two varieties i.e. CoH 119 (29.28%) and CoJ 85 (35.15%). The incidence of stalk borer increased from 3.70 t0 69.63 percent with increase in nitrogen level from 0 to 90 kg N/ac. The highest cane yield was obtained from the CoH 119 variety at 60 kg N/ac.
