SIDDIQUI, Tahir; FATTAKH NAWAZ, Muhammad  e  AHMED, Irfan. Effect of different pruning intensities on the growth of Acacia nilotica (Kikar). Agrociencia [online]. 2010, vol.44, n.1, pp.93-97. ISSN 2521-9766.

In many species, natural pruning is never a satisfactory option if production of clear wood is a management objective. Acacia nilotica is well adapted specie to the arid and semiarid climate of Pakistan and plays an important role in rural economy of the country. Traditional pruning is carried out to maximize the amount of clear-wood production but the effect of this practice on tree growth, still unknown. So a preliminary pruning trial was conducted at two different sites, UAF and PARS, in Faisalabad- Pakistan. All pruning treatments resulted in reduction in diameter growth. However, significant reduction in diameter growth was observed when crown removal was more than 40 %. A taper study was done by taking diameter measurements at different heights. The results revealed that pruning treatments have a significant effect on tapering of the stem. In general, there was a diameter decrease of 1 cm on every 1 m in height.
