The field experiments were conducted to evaluate response of promising sugarcane genotypes to fertilizer levels during preseason of the years 2009-10 and 2010-11 at Central Sugarcane Research Station, Padegaon. The sugarcane genotype Co 310 produced significantly higher cane and CCS yield (132.26 and 18.62 t ha-1, respectively) than rest of genotypes tested. The application of 125 % recommended dose of nitrogen to preseasonal sugarcane produced significantly highest cane and CCS yield (132.92 and 18.79 t ha-1, respectively). Growth and yield attributes viz; millable height, girth and millable cane/ha were significantly highest with the genotype Co 310 irrespective of nitrogen levels. The fertilizer level of 125 % nitrogen to preseasonal sugarcane registered significantly highest growth and yield attributes viz; millable height, girth, no. of internodes/cane, millable cane/ha and weight/cane as well as quality paratmeters viz; brix, sucrose and CCS.
