Abstract

The study investigated total carbon stocks in two Citrus sinensis (L) plantations at the Akpera Orshi Polytechnic, Yandev Gboko, Nigeria using a non-destructive approach. AGB of Citrus trees was determined using the allometric model AGB = Volume x Density while BGB was determined as 20% of AGB. Herbaceous and litter biomass were determined as oven dry weight /(1m2) quadrat. AGB and BGB varied among sampling plots in both plantations, with highest values in plantation 2(10.39 and 2.08). The TSC and SCO2E was highest in plot 1 (4.43 and 16.24) of plantation 1 and plot 3 in plantation 2(5.20 and 19.07). Total number of herbs was highest in plantation 1 (28 species, Shannon index, 3.1 4).  The highest herbaceous biomass (155.13 g) and plot 1 of Plantation 2 (140.20 g). Also, TSC and SCO2E were highest in plot 2 (77.57 and 284.66) of plantation 1 while in. plantation 2, both were highest in plot 1 (70.10 and 257.27). Litter biomass was highest in plot 2 of Plantation 1 (129.89 kg) and plot 3 of Plantation 2 (151.46). Similarly, TSC and SCO2E in herbs were highest in plantation 2, plot 3 (75.73 and 277.93). AGB correlates positively with DBH (P˂0.000, R = 0.857, Y=-4.98+2.79*X) and plant height (P˂0.000, R = 0.647, Y=-4.98+2.79*X), Suggesting, that AGB increases with increasing DBH and plant height respectively. The study reveals the importance of agroforestry in climate change mitigation.
