To investigate the effect of different mulches on the survival and growth of tree species and experiment was laid put at Rakh Dagar Kotli in Thal desert. Acacia modesta and A. torrilis were planted with plastic apron, stone pitching, and grass mulch and without mulch in March, 1981. Observations after one year and two months revealed that the mulches did not have any effect on the survival of plants. However, out of the lour treatments, plastic aprons were significantly effective in improving the growth rate of both the species; stone pitching and grass mulch had rather negative effect on growth.
