**5. Carbon stock contribution by crop in agroforestry across altitudes**

Forty crops species associated in agroforestry systems were observed in the district. Out of forty, maximum biomass carbon containing crop species are *Solanum tuberosum* (4.49%), *Curcuma longa* (4.43%), *Tetricum estivum* (4.01%),*Ehinochloa frumentacea* (3.98%)*, Amarnathus blitum* (3.78%), *Fagopyrum esculenta* (3.56%), *Eleusine coracana* (3.4%)and *Glycine max* (3.33%) and rest of the species contributes (55.74%) biomass carbon stock (**Figure 3**). In the present study *Solanum tuberosum* contributed maximum biomass as compared to other crop species. It may be attributed that *Solanum tuberosum* had maximum leaf area and dry weight as compare to other crop species. Due to large leaf area, it is capable for absorption of maximum sunlight and has a maximum amount of CO2 fixation [51, 52].
