Abstract
Carbon sequestration through biotic technique has many advantages. Hence study has been taken up to understand the carbon sequestration in agricultural crops by considering the twenty-five agricultural crops grown in Tumakuru district. In the present study non-destructive method of estimation of the carbon sequestration was adopted with the help of thirty years taluk-wise data from 1986-87 to 2015-16 on area and production of different crops. To analyze the spatial and temporal disparity in carbon sequestration, twenty-five crops were grouped into six crop groups based on the similarities between
them and the study period was divided into three decades. Declining trend was observed in area and production of twenty-five crops considered for the district as a whole, however the estimates of carbon sequestration didn’t show the similar trend. Among the six crop groups considered in the study, cash crops showed high potential in sequestering the carbon, whereas, pulses and oil seeds were less potent in sequestering the carbon. Results clearly indicated the presence of disparity in the carbon sequestration among the crop groups over decades which were tested using the modified Friedman’s two-way analysis. An attempt was also made to analyse the spatial disparity using cluster analysis.
To identify the contribution of each crop groups for total spatial variability in carbon sequestration, factor analysis was adopted. Results revealed that, Madhugiri and Sira taluks have substantially contributed for higher carbon sequestration while Tiptur and Turuvekere were clustered under low carbon sequestering taluks based on the crops considered under the study.
