Efficacy of urea and ethrel on growth, induction of flowering, fruit-set, fruit retention, fruit quality and yield was evaluated under high density planting of guava cv. Allahabad Safeda. Urea (15%) increased plant height, length of longest shoot, leaves/plant, fruit retention and yield at 38 months old seedlings. Ethrel (1000 and 2000 ppm) and urea (20 and 25 per cent) caused dwarfing effect desirable for high density planting. Spraying of urea or ethrel did not influence fruit quality. However, ascorbic acid and acidity were increased by urea at 15 per cent concentration. The findings suggest the use of 15 per cent urea spray for early cropping under high density planting (2500 plants/ha).
