Abstract

ABSTRACT Dalbergia sissoo (Shisham) is the major species planted in the irrigated plantations and riverain forests over a period of time. It can be regenerated from root suckers, from coppice and by planting root-shoot cuttings. For the last one hundred years the tree has been planted at a conventional spacing of 6 x 10 ft. To release the congestion and depending on the condition of the crop, first thinning is done in the 6th year, the second in the 12th, another in the 18th year if need be, and the final felling at the age of 20-22 years. In order to find out the effect of spacing on the pattern of growth, a study was laid out in the Pakistan Forest Institute Research Garden in January, 1978.
