Abstract : A field experiment was conducted in Pantnagar, Uttar Pradesh, India, to study the effects of crop density (400, 177, 100, and 64 trees/ha with corresponding spacing of 5.0×5.0, 7.5×7.5, 10.0×10.0, and 12.5×12.5 m) on the yield and quality of mango cv. Dashehari. Dashehari scions were grafted on seedling rootstocks in 1986. Growth (in terms of scion length, main scion stem diameter, and canopy circumference) and yield were evaluated from 1987 to 2000. Growth, which did not differ with crop density, was slow during the initial 5 years. Thereafter, growth had increased linearly before decreasing after year 10. Fruit yield per tree and fruit quality (fruit weight, volume, length, diameter, and total soluble sugar content) did not differ with density. After year 7, however, fruit yield per hectare increased with the increase in density. The highest yield (18 t/ha) was recorded during year 14 in plots with the highest density (400 trees/ha).
