Abstract: The present study was aimed at improving growth and development of two planting materials (bud chips and three budded setts) of sugarcane cultivar 2003T121 by pre-planting soaking in growth-promoting chemicals viz Cow dung slurry (20%), Ethereal (100ppm), Calcium chloride (2g/lit), CEPA (5ppm), Calcium chloride+CEPA, along with control and water soaking for 24 hrs. Treated planting materials showed better results in all growth and biochemical attributes. Leaf area index and crop growth rate were found to be more in water soaking (1.33,9.75) and CaCl2+CEPA (1.27,9.68) in three budded setts where as in bud chip raised seedlings LAI was recorded highest with water soaking (0.43) treatment, lowest values were seen in Cow dung slurry (0.22) CGR recorded highest with CaCl2+CEPA (2.61). Reducing sugars and brix values were also recorded high in CaCl2+CEPA (2.87) and T2 Water soaking (2.87) whereas lowest values were recorded in T1 (Control) (1.62)and T3 (Cow dung slurry) (1.74).
