Old river bed lands in the NorthWest Himalayas have generally been utilized for
the production of fodder and firewood but its quantative biomass production and
resource (carbon and water) conservation potential have not been worked out.
Plantations of three tree species-Grewiaoptiva Drumm,Bauhiniavariegata L.
AndDalbergiasissoo Roxb.were raised during 1996, at 2x2m (close), 3x2m
(medium) and 4x2m(wide) spacings and were thinned mechanically at the age of
7, 12 and 15 years. The performance of D.sissoowas the best with trees attaining
an average height of 9.87 m and 10.3 m in the 7 year and 12 year, respectively.
G.optivatrees attained an average height of 5.67 m and 6.20 m at the same age.
Foliage (as fodder) availability from annual prunings inG.optiva declined from
the 11 year and woody biomass from the 8 year. More woody biomass was
obtained at medium spacing and that of foliage at close spacing. First thinning in
the 7 year yielded 54.70, 20.45 and 13.65 t ha of woody biomass at close spacing
inD.sissoo ,G.optiva andB.variegata , respectively, followed by production from
medium and wide spacing. During the 2 thinning at the 12 year, maximum
woody biomass (100.50 t ha ) was obtained fromD.sissoo at medium spacing
followed by 53.43 t ha from G.optivaat wide spacing and 34.94 t ha fromB.variegata
at medium spacing.Annual rate of increase of SOC in the 0-45 cm soil
depth ranged from 502 to 1410 kg C ha . The humification rate was determined to
be 0.195. Carbon sequestration rate varied from 1.32 to 0.55 t ha yr and followed
the trend of D.sissoo
