A study was carried out to identify the best rotation age of Dalbergia sissoo (Shisham) trees growing at Chichawatni Irrigated plantation in Punjab, Pakistan during the year 2012.Three rotation options were studied viz. (1) 21 years rotation being practiced presently, (2) two rotations, first of 10 years and second\next of 11 years comprising a total of 21 years and (3) three successive rotations of 6 years each and last rotation of 3 years with a total span of 21 years. The data required for this study were collected from the office of Sub–Divisional Forest Officer, Chichawatni plantation. Trees of all age groups from year 1 to year 21 were present in the plantation. So, the data on the establishment cost and maintenance cost of the plantation from 1st to 21st year were collected. The data were discounted at 8 percent discount\interest rate. Results indicated that plantation of Shisham was in financial loss under all rotation options. However, maximum net present worth (Rs. –287485.73 ha 1) was obtained under third rotation option against minimum (Rs. 564408.12 ha 1) under first rotation system. Similarly maximum benefit cost ratio (0.77) and return on investment ( 22.48%) were also found in third rotation system against minimum (0.53 and –46.56% respectively) from first rotation system. The results further indicated that cultivation of Shisham under existing rotation of 21 years is unprofitable. However, the economic losses can be significantly reduced by adopting the third rotation option. It is recommended that other agro–forestry options including tree–livestock, tree–poultry farm, tree–farm crops etc. should be tested to see whether net present worth may be made positive or not.
