The effect on carbon sequestration under saffron (Crocus sativa) cultivation as influenced by different levels of organic manure and inorganic nitrogen was investigated in a field experiment at Dryland (Karewa) Agriculture Research Station, Budgam, Kashmir. The farm yard manure was applied at 0, 30 and 60 t ha-1 and inorganic nitrogen at 0, 45 and 90 kg ha-1, respectively along with Azotobacter. The organic carbon content was recorded at three stages, immediately after flowering (Oct-Nov), during vegetative growth stages in (Feb- March) and (April-May), respectively. The pooled data indicated that at stage I, there was a significant increase in the organic carbon in the soil with the application of maximum amount of FYM and nitrogen. The mean organic carbon content of the soil increased from 9.22 g kg-1 to 15.34 g kg-1 when FYM was applied in conjugation with inorganic nitrogen. However, the highest and significant organic carbon (17.50 g kg-1) was observed in the treatment in which nitrogen was applied at 90 kg ha-1 and FYM at 60 t ha-1 an increase of 156.9 per cent over the control (6.81 g ha-1). Similar trends were also observed at stage II and III, respectively. However, the effect of Azotobacter was found significant only at stage-III.
