Abstract : Early blooming and flower malformation, the principal factors of crop failure, were corrected by spraying urea just before flower bud differentiation in mid-November. Urea sprays delayed time of flower bud opening, decreased the incidence of flower malformation, and affected the development of panicles by increasing the number of perfect flowers, improving pollen grain viability and increasing fruit set and fruiting. The best results were obtained by 1-2% urea which increased tree fruit productivity 8 times.
