Abstract

Effect of double ditch method of planting on growth characteristics of some forest tree species.

Abstract

The double ditch method of planting is a new water conservation technique for use in low rainfall areas. The method involves digging up the soil around the plant (which is established in a pit) to 23 cm depth and using it to form a circular bund of 1 m diameter around the plant (with a mouth of 30-38 cm) and a middle bund across the circle (with the plant in its middle) which divides the whole surrounded pit into 2 ditches. The technique was tested in the forest ranges of Panna Forest Division, Madhya Pradesh using a selection of forest/multipurpose tree species. Growth data are presented for some of these (Dendrocalamus strictus, Tectona grandis, Phyllanthus emblica, Terminalia arjuna, Eucalyptus, Azadirachta indica, Dalbergia sissoo, Albizia procera) at 2 and 3 yr old. All the species grew better in the double ditch planting method than the control [normal pit planting method], with Tectona grandis, Dendrocalamus strictus and Phyllanthus emblica giving the most promising results.
