Abstract : Effect of time of urea spray on irregular bearing of most commercial cultivars of mango (Chounsa, Dushehari and Anwar Ratool) of Pakistan was investigated. Various concentrations of low biurete urea (LBU) were sprayed in February, 2005 (before blooming) and September, 2005 (After harvest at flower bud differentiation) and its effect on blooming of tagged shoots was studied during on year 2005. Percentage of emergence of vegetative and flowering buds on shoots emerged during on year 2005 was recorded during off year 2006. Means and standard deviations of results reflected that there was significant effect of time and concentration of urea spray on blooming as compared to control. Significantly high blooming was recorded in off year on plants, received 3% urea compared with control.
