Abstract : An experiment was conducted in Rajendranagar, Hyderabad, India, to determine the effect of pre-sowing treatments on germination, growth and vigour of mango during 2010-2011. Significantly higher values for all growth attribute parameters were recorded with the treatment (T9) i.e. extracted kernel pre-treated with KNO3 @ 0.5 per cent found to be sound integrated practice, where it recorded maximum germination percentage (64%), seedling diameter (7.10 mm), number of leaves (10.90), leaf length (15.83 cm), leaf width (8.00 cm), root length (23.40 cm), root spread (8.66 cm), root to shoot ratio (0.807), vigor of seedling (1094.33) and vigor index (1517.30) over all the other treatments. Whereas maximum seedling height (24.13 cm) and internodal length (3.66 cm) was recorded in extracted kernel pre-treated with GA3 @ 500 ppm.
