Abstract

ABSTRACT To test the efficacy of the pitcher irrigation for the establishment of tree vegetation in arid conditions, experiments were conducted at Rakh Dagar Kotli in 1980 and 1981. Acacia modesta and E. camaldulensis were planted around the pitchers at a distance of half a meter from the centre of the pitchers. Using diluted bitumen the pitchers were half surface painted,2/3rd surface painted and whole surface painted except four circular areas left on the four opposite sides to reduce the perculation rate of water. It was found that pitcher irrigation is a useful technique for the establishment of tree vegetation in the arid conditions. The results also indicated that the painting treatments to the pitchers could out prove effective to increase the survival percentage and growth rate of both the tree species.
