Above ground biomass produced by D. asper at two aspects varied. Biomass produced in two years after the<br />
plantation was 17 per cent higher at the hill top as compared to river bank on the fresh weight basis. Average<br />
biomass produced was 542.24 kg ha -1 <strong>and</strong> 450.06 kg ha -1 at ARS Majhera <strong>and</strong> Jarmila, respectively. Dry weight<br />
was recorded approximately 63 per cent less than the fresh weight (Table 2). Average biomass on the basis of<br />
dry weight was 208.43 kg ha -1 at ARS Majhera which was 19.8 per cent higher than Jarmila (166.99 kg ha -1 ).<br />

Soil carbon concentration in both the aspects was estimated up to 20 cm depth. Soil carbon of the hill top was<br />
found higher than the soil carbon of river bank. Negative correlation was found between the per cent soil carbon<br />
<strong>and</strong> radial distance from the centre of the plant (Table 3). Per cent soil carbon increased by 64-70 at ARS<br />
Majhera <strong>and</strong> 32-60 at Jarmila due to litter deposition (leaf fall) as compared to control.<br />

There are few studies on biomass production by D. asper. Mathematical regression models are commonly<br />
practiced in determining the biomass of forest all over the world because it does not damage the growth of the<br />
