Abstract :

Jamun (Syzygium cuminii Skeels) is an important indigenous minor fruit of commercial value. Foliar application of growth regulators and macro nutrients are known to enhance the growth of seedlings of various fruit crops. The present investigation was carried out to reduce the time required to reach graftable size of jamun seedlings using growth regulators and macronutrients at Regional Horticultural Research and Extension Centre, Bengaluru during the year 2012–2013. The foliar application of GA3 at 300 ppm found to be beneficial to enhance the seedling height (57.66 cm), diameter (6.06 mm), fresh weight (94.66 g) and dry weight (35.86 g) and to reduce the number of days taken to reach graftable size (132.72 days) compared to control.
