Table 8: Mean± S.E values of AGB (Mg ha^-1), BGB (Mg ha^-1), AGB-C stock (Mg ha^-1) and BGB-C stock (Mg ha^-1).

Land Use	AGB	BGB	AGB-C	BGB-C
Open grazing land	12.60±6.20^b	3.15±1.55^b	5.92±2.91^b	1.66±0.82^b
Young age exclosure	22.81±5.26^b	5.70±1.31^b	10.72±2.47^b	3.00±0.69^b
Middle age exclosure	68.61±12.47^a	17.15±3.12^a	32.25±5.86^a	9.03±1.64^a
Old age exclosure	67.85±15.96^a	16.96±3.99^a	31.89±7.50^a	8.93±2.10^a
p-value	< 0.001	< 0.001	< 0.001	< 0.001
CV%	76.21	76.21	76.21	76.2

Means ±S.E. with different letters within a column are significantly different (p < 0.05) (Tukey’s test HSD).
AGB = Aboveground biomass, BGB = Belowground biomass, and C = Carbon.
