ABSTRACT
An experiment was laid out to assess the effect of depth
of planting on the survival and establishment of trees
in conditions at Rakh Dagar Kotli (Thal Desert) 200mm
av. annual rainfall and 45°C av.minimum and 45°C av. max
temperature. Pits were prepared having 0.5 meter
diameter and 0.2 meter deep. Plants were raised in 30 cm
and 15 cm long polythene tubes. Three tree species viz:
Acacia aneura, A. tortilis and Tecoma undulata were
planted at two depths i.e., 30 and 18 cm in July 1980.
After one and half year it was found that in deep planting 64%
plants of all species survived and in shallow planting
54%. In both depths maximum survival was of A. tortilis
being 75% followed by 58% of T.undulata and 44% of
A.aneura. In deep planting the average height of plants
was 76 cm and in shallow planting it was 60 cm. A.
tortilis showed better rate of growth as the average
height gained by the plants during the period was 102 cm
at both depths. While average height of T.undulata and
A. aneura were 54 cm and 49 cm respectively.
