| Abstract:
Feasibility of high density orcharding in Dashehari mango was assessed in a field trial in which veneer grafts were planted in 1976 at two spacings : (i) 3.0 x 2.5 m (1333 trees/ha; high density); (ii) 12 x 12 m (69 trees/ha; low density). In July 1987, soon after crop harvest, ¾ of the canopy of trees in the high density orchard were dehorned and the remaining ¼th was deborned in July, 1988. Thus, the height and spread of the trees in high density were reduced to about half in the 10th year. Prior to pruning, trees in high density had more height but less stem diameter and spread as compared to trees in low density. Although per tree yield was more in low density than those of high density, the total yield was about 14 times more from the high density orchard. During 11th and 12th year of tree age, when height and spread of trees in high density was reduced to about half by dehorning, the yield per tree was also reduced by the same ratio. However, the total yield from high density plantation was about 10 times more than those planted at normal density during this period, when trees in high density were pruned. Thus, high density plantation of Dashehari produced more fruits (10–14 times) than those planted at low density. | |
